Now let me turn the call over to Lee.
Thanks, Ashley. Good morning, everyone and thank you for joining our third quarter earnings call. As I take part in my last Tradeweb earnings call, I sit back and reflect upon this startup that I co-founded over 25 years ago with $10 million in capital. The core approach was simple. Listen to our clients and build services, products, protocols and functionalities that enhance their trading workflows. Over those 25 years, the talented Tradeweb employees have grown this institutional U.S. Treasury startup into a global multi-asset class, multi-client and multi-protocol business. One of the crowning achievements was the 2019 IPO, followed by the tremendous growth the team has produced as a public company. In fact, from 2004 through 2021, we've averaged 12.9% annual revenue growth.
In the first three quarters of 2022, we generated revenues of $896 million, up 55% from the first three quarters of 2019 or an average growth of 16% per year, despite the material FX headwinds we're currently facing in 2022. The lion's share of this growth has been organic as a result of relentless focus on innovation and collaboration that continues to be the North Star of our company as we help clients trade as efficiently as possible. This strategy sounds simple, yet success requires perseverance. Our team has dedicated the time and focus to link different liquidity pools and markets to deliver holistic, global, multi-asset class solutions, something we call connecting the dots.
This incessant focus on moving markets forward has allowed us to develop a diversified business model that allows the company to drive strong revenue growth, even when facing a challenging macro environment in some of our products and client channels. I'm thrilled to pass the baton to my longtime friend and partner, Billy. I'm excited to see him, Tom, Sara and Enrico Bruni, who's the head of Asia and Europe, Chris Allen, who built our institutional U.S. Credit business, Justin Peterson, our Chief Technology Officer and the entire Tradeweb team as they continue to build upon our competitive advantage, our people, network and technology. I'm excited to watch the team capitalize on the long-term growth runway ahead and most of our markets still trading over the phone.
Turning to slide four, record third quarter revenues of $287 million were up 8.2% year-on-year on a reported basis. The underlying strength in the business was even better. Stripping out the 490 basis points of FX headwinds that have been the most severe since we went public, we generated strong revenue growth of 13.1% on a constant currency basis and another double-digit revenue growth quarter. The revenue growth and the resulting scale translated into improved profitability relative to full year 2021. As our year-to-date adjusted EBITDA margin increased by 83 basis points to 51%. Adjusted earnings per share saw a healthy growth of 15% year-on-year. Turning to slide five. The diversity of our growth was on display once again this quarter, marked by double-digit constant currency growth across all of our asset classes.
Rates and credit continue to lead the way, accounting for 40% and 27% of our revenue growth respectively, while equities provided 22% of the growth, a high-water mark in terms of growth contribution. Specifically, rates posted its best third quarter revenues ever, driven by our continued growth across global government bonds and swaps. In cash rates, U.S. Treasury revenues were up nearly 10% year-on-year, given the acceleration of our retail business due to the higher rate environment. Swaps produced another strong quarter with positive market share growth, while mortgage revenues declined given the challenging rate backdrop. Credit posted another strong quarter driven by strong munis, U.S. corporate credit and CDS trading. Equities posted its highest third quarter revenues ever, driven by institutional ETFs and our effort to diversify and grow our other equity products.
Money markets set a new record fueled by growth in our retail CD franchise and continued organic growth in institutional repos. Finally, market data revenue growth was equally split across our Refinitiv contract and our proprietary data products, which continue to enjoy robust growth. Moving on to slide six, I will provide a brief update on two of our main focus areas, U.S. Treasuries and ETFs and turn it over to Billy to dig deeper into U.S. Credit and global interest rate swaps. Starting with U.S. Treasuries, our market share fell slightly to 19.6% of the U.S. Treasury market. The slowdown that we saw in the second quarter within our institutional asset manager and hedge fund clients as they moved to the sidelines and trimmed risk as volatility spiked persisted into July.
Activity started to improve exiting July, with both August and September registering month-over-month increases. The leading indicators of the institutional business remained strong. We gained market share versus Bloomberg and client engagement was good, with the number of users increasing by 10% year-on-year and 3% quarter-over-quarter. On the other hand, our wholesale performance was mixed as our legacy streaming offering saw a positive revenue growth while our CLOB underperformed as elevated volatility benefited the incumbent. Recall when we acquired NFI, the first phase of our integration plan was focused on expenses, consolidating broker-dealers and technology platforms and migrating the data center. We will be consolidating the broker-dealer shortly and plan to migrate data centers during the first half of 2023.
After we migrate the data center, we expect that to be a catalyst for revenue growth as we rebuild the liquidity pool. On the whole, we believe the U.S. Treasury business is in a unique position with deep retail, wholesale and institutional liquidity pools, giving us the ability to continue to grow and capitalize on any potential market structure change. Finally, within equities, institutional ETFs produced strong quarterly revenue growth, with average daily volume up 43% year-on-year, driven by new client wins and strong industry volumes. The client pipeline remains strong as the benefits of our electronic solutions continue to resonate. Structurally, we are seeing an increase in cross-asset trading, whereby ETF RFQs are being placed by both fixed income and equity trading desks.
Our other initiatives to expand beyond our flagship ETF franchise are also bearing fruit, with momentum continuing in the equity options, convertibles and ADRs. We look forward to crossing the $100 million annual revenue mark in the coming quarters and we believe we remain well-positioned to benefit from the secular growth in the ETFs and our other growth initiatives scaling. With that, I'll turn it over to Billy.
Thanks, Lee and congratulations on a terrific run at Tradeweb. As Lee highlighted in his opening, we have methodically grown our asset class, geographic and client footprint over the last 25 years. One thing that has been constant at Tradeweb is our singular focus on collaborating with our clients to drive change in the fixed income markets. Despite all the success we've had to date, I believe the best is yet to come. In fact, we just completed an offsite where we gathered our senior leaders and discussed our growth outlook for the next few years. The energy and optimism around the durability of our growth was remarkable. We expect credit and swaps to continue to be the backbone of our growth but we'll also be expanding our EM and muni footprint in a meaningful way.
As you might expect, we are also working on a few more initiatives that we will reveal in due course. I am truly excited about the team that we have assembled and our ability to deepen our competitive advantage across our people, network and technology. On that note, I'd like to officially welcome Tom Pluta, who joined as president-elect at the beginning of the month and I believe he will be a valuable addition as we look to grow Tradeweb's footprint over the coming years. Turning to slide seven for a closer look at credit. We quite often talk about the diversity of the business across asset classes but the diversity within each asset class shines in moments like this.
Corporate credit faced a mixed industry volume backdrop given the elevated volatility, continued fee per million pressures across institutional IG due to a reduction in duration and tougher market share conditions across high yield. However, the elevated volatility and wider spreads continued to boost our CDS business and the higher rates helped drive nearly 90% year-over-year revenue growth in our muni and retail and middle market credit businesses. The product of this was a healthy quarter with 12% year-over-year constant currency revenue growth. It's amazing to see our growing credit business now annualizing over $300 million in revenues led by U.S. Credit. We have a differentiated strategy in U.S. Credit and we continue to work on building out that puzzle, expand our client network, grow our all-to-all volumes and develop our integrated strategy across client channels.
Electronically, credit is a young market with plenty of potential for further innovation and we believe that our holistic credit approach and strong feedback loop with clients will continue to help us expand our network. We are excited to hit new fully electronic market share records in IG and we believe further investments in high yield can lead to a similar outcome in the coming quarters and years. Our institutional volume growth continues to be underpinned by growth in RFQ and portfolio trading. Our third quarter RFQ average daily volume grew 14% year-over-year, driven by investment grade. RFQ remains the main protocol in the U.S. Credit market but we realize that the protocol hadn't evolved very much over the last 15 years.
Rather than imitate, we reimagined the RFQ protocol to create a differentiated client trading experience and we are excited about the initial positive results that we have achieved over the past few quarters. Expanding our RFQ presence across IG and high yield remains our biggest opportunity and we continue to see great success cross-selling the innovations we have brought to the credit market to gain wallet share. Despite the continued increase in spreads and volatility, we also continue to see strong portfolio trading activity on the platform, with average daily volume growing 13% year-over-year and September being another record month. The underlying trends remain impressive globally. The number of users are up 15%, while the line items traded were up over 35% year-over-year. In the quarter, our largest trade was greater than $2 billion.
Behavior change takes time but clients are increasingly using our market-leading portfolio trading solution to access greater liquidity, minimize information leakage, improve certainty of execution, trade less liquid instruments more efficiently, trade credit portfolios at the close and reduce workload and operational risk. The strength in RFQ when portfolio trading was matched by the strong growth of our anonymous liquidity solution, AllTrade, which saw nearly $100 billion in volume, with average daily volume increasing 12% year-over-year. Our all-to-all liquidity volume saw positive year-over-year growth across IG but faced tougher client conditions within high yield. While high yield volumes were down year-over-year, the number of high yield all-to-all responders increased by 12% year-over-year and is up 40% since the beginning of 2021, giving us confidence that we can continue to deepen our liquidity pool moving forward.
Session volume saw double-digit volume growth led by IG, while high yield faced tougher hit rate conditions given more one-way submission flow. Finally, we remain laser-focused on maximizing the value of sessions liquidity uploaded on our platform through newer protocols like Rematch, which accesses our all-to-all liquidity. Our Rematch average daily volume was up nearly 80% in the third quarter. Turning to the non-U.S. Credit business, revenue grew 17% year-over-year and continued to perform well in the current market environment. Our muni business achieved record third quarter revenues as the retail market sprung back to life and the institutional business, which grew more than 150% year-over-year, continues to attract new clients. We'll be leveraging our leading presence in the tax-exempt muni space to expand our institutional offering to include taxable munis soon.
Our recent rollout of our Ai-Price for munis has gone well and we recently partnered with SIX Financial to redistribute our muni data. Another area of focus over the coming years is emerging market credit. Our current EM portfolio trading offering continues to scale and we are methodically expanding our presence across all rates and credit products. We believe our position as a global multi-asset class firm gives us a unique one-stop shop proposition, being able to offer EM products across swaps, CDS, credit and China bonds to our clients. The continued volatility in the market boosted our CDS revenues, which grew 45% year-over-year, with strong growth across regions. Finally, we are excited about our collaboration with S&P Global Market Intelligence to introduce electronic connectivity between primary and secondary markets across European credit, covered sovereign, supranational and agency bonds.
In sum, it was another solid quarter for credit and we continue to see a lot of opportunity in credit as our institutional and wholesale platform continues to scale and the retail business continues to thrive. Moving on to swaps, the multi-year growth story continues as swaps registered another strong quarter, aided by rebounding industry volumes and market share gains. Our variable swaps revenue grew 23% year-over-year, driven by strong growth across tenors and market share climbing to 15.2%. Since the beginning of 2019, the swaps industry has fluctuated from high growth to negative growth, high rates to zero rates and now back to higher rates and fluctuating volatility.
Over those 15 quarters, our swaps business has produced an average of 30% year-over-year revenue growth, a testament to the resiliency of our market-leading swaps business and the strong growth opportunity that we feel is underappreciated. Our momentum in major currencies continues, with record year-to-date share in dollar, euro, pound and EM-denominated swaps. We believe the LIBOR transition is progressing well. 50% of our year-to-date volumes came from SOFR trades, up from 14% in the year-ago period, with 95% of our dollar swap clients having executed a SOFR-based trade since the start of the year. Inflation and upward pressure on commodity prices have shown little sign of abating. Central banks continue to raise interest rates to help counter rising inflation. However, such uncertainty means market participants have had to make longer-term decisions about how they hedge their exposure to inflation.
Since executing our first cleared inflation swap transaction in 2017, Tradeweb has carved out a leading position in the electronic execution of inflation swaps. Just another example of us helping our clients improve their execution experience. Year-to-date inflation swaps volumes are up 60% year-over-year. Beyond the risk-free rate transition and inflation swaps, we continue to respond to structural changes in the swaps market, making strong advances in cleared EM swaps and RFM protocol adoption. We saw record EM share in the first nine months of the year, with revenue increasing by over 100% year-over-year. We believe if we increase our market share by an incremental 10% of the cleared EM market, that could add up to an additional $15 million in variable revenues, assuming current market average daily volumes. The long-term opportunity is even larger.
Since 2017, Clarus EM IRS average daily volumes have increased at an average of 24% per year. Finally, we also saw record RFM activity as we continued to onboard dealers and deepen our liquidity pool globally. Looking ahead, we believe that the long-term swaps revenue growth potential is meaningful. With the market still only 30% electronified, we believe there remains a lot that we can do to help digitize our clients' manual workflows while the global fixed income markets and broader swaps market grow. With that, let me turn it over to Sara to discuss our financials in more detail.
Thanks, Billy and good morning. As I go through the numbers, all comparisons will be to the prior year period, unless otherwise noted. Let me begin with an overview of our volumes on slide nine. We reported record third quarter average daily volume of nearly $1.1 trillion, up 14% year-over-year and up 12% when excluding short tenor swaps. Among the 22 product categories that we include in our monthly activity report, 10 of the 22 product areas produced year-over-year volume growth of more than 20%. Areas of strong growth include European government bonds, global swaps, US investment-grade credit, munis, credit swaps and global ETFs. Slide 10 provides a summary of our quarterly earnings performance. The third quarter volume growth translated into gross revenues increasing by 13.1% on a constant currency basis, continuing our track record of double-digit revenue growth.
FX headwinds of 490 basis points led to reported growth of 8.2%. We derived approximately 36% of our revenue from international customers and recall that approximately 30% of our revenue base is denominated in currencies other than dollars, predominantly in euros. Our variable revenues increased by 14.8% and our total trading revenue increased by 8.6%. Total fixed revenues related to our 4 major asset classes were down 5.1% but were flat on a constant currency basis. Rates fixed revenues were down given the migration of certain European government bond clients from fixed to variable contracts at the end of last year and the impact of FX. Money markets fixed revenue growth was driven by global repos. Other trading revenues were down 2%.
As a reminder, this line does fluctuate as it is affected by periodic revenues tied to technology enhancements performed for our retail clients. Market data increased by 3.4% due to growth in Refinitiv and our proprietary data products. This quarter's adjusted EBITDA margin of 51% increased by 86 basis points on a reported basis and 130 basis points on a constant currency basis relative to the third quarter of 2021. Similarly, our adjusted EBITDA margin for the first nine months of 2022 increased by 83 basis points on a reported basis and 109 basis points on a constant currency basis from the full year 2021. We remain committed and on track to deliver annual margin expansion in 2022 and there's been no change to our philosophy of balancing revenue growth with margin expansion.
All in, we reported adjusted net income per diluted share of $0.45. On slide 11, we contextualize the impact of FX on our historical results. The key takeaway here is the extreme moves in FX this year are unprecedented and are masking the strength and consistency of our constant currency revenue growth. Specifically, the third quarter FX headwinds of nearly 500 basis points were driven by a 14% decline in the euro relative to the US dollar, which is the highest decline we have seen year-to-date and remains in October. That said, when you compare our constant currency growth rates versus prior years, you can see the continued momentum across our business. This is a testament to the diversity of our business model across asset classes, protocols, geographies and client channels.
This diversity allows us to uniquely navigate different macro environments while the secular story of electronification unfolds. As Billy highlighted, we are excited about the growth potential that lies in front of us and we believe we have multiple significant initiatives that will help us to continue to drive double-digit revenue growth over the long term. On top of our own initiatives, as yields increase across fixed income, we expect the interest from clients investing and trading in fixed income products to continue to increase. Moving on to fees per million on slide 12. The trends I'm about to describe are driven by a mix of the various products within our four asset classes.
In sum, our blended fees per million increased 1% year-over-year, primarily as a result of stronger growth in higher fee per million rates derivatives and cash equities. Excluding lower fee per million short tenor swaps and futures, our blended fees per million were up 3%. Let's review the underlying trends by asset class, starting with rates. Average fees per million for rates were up 4%. For cash rates products, fees per million were up 14%, primarily due to a positive mix shift towards higher fee per million U.S. Treasuries and the migration of certain European government bond clients from fixed to variable contracts at the end of last year. For long tenor swaps, fees per million were down 7% primarily due to lower duration, while we continue to see growth in EM swaps and RFM.
In other rates derivatives, which includes rates futures and short tenor swaps, average fees per million increased 34% due to a shift towards rates futures, which carries a higher fee per million than the group average and a core increase in OIS fee per million. Continuing to credit. Despite the higher fee per million across cash credit derivatives and electronically processed U.S. cash credit, average fees per million for credit decreased 17% due to relative product mix, with stronger volume growth in lower fee per million credit derivatives and electronically processed trades. Drilling down on cash credit, average fees per million increased 4% despite the continued U.S. high-grade fee pressures due to stronger growth in U.S. high-grade and munis, which both carry a higher fee per million than overall cash credit.
Notably, our fully electronic U.S. high-grade volumes were a record in the third quarter. Looking at the credit derivatives and electronically processed U.S. cash credit category, fees per million increased 3%, driven by stronger growth in European index CDS, which carries a higher fee per million than the group average. Continuing with equities, average fees per million for equities were up 23%. For cash equities, average fees per million increased by 20% due to an increase in fees per million within U.S. ETFs, which was driven by a decrease in notional per share traded. Recall in the U.S., we charge per share and not for notional value traded. Equity derivatives average fees per million increased 1% due to an increase in convertibles fee per million. Finally, within money markets, fees per million increased 2%.
This was primarily driven by a mix shift towards U.S. CDs, which offset a decrease in our U.S. repo fees per million. In addition, the higher fee per million retail money markets business continues to improve given the higher interest rate environment. Slide 13 details our expenses. Adjusted expenses for the third quarter increased 6.8% and 10.4% on a constant currency basis. Recall that approximately 15% of our expense base is denominated in currencies other than dollars, predominantly in sterling. The third quarter of 2022 adjusted operating expenses were higher as compared to the third quarter of 2021, primarily due to increased employee compensation, technology and communication and G&A. Compensation costs increased 4.6% due to higher headcount.
Adjusted non-comp expense increased 11.1%, primarily due to technology and communications, G&A, D&A and professional services but were helped by favorable movements in FX. Adjusted non-comp expense on a constant currency basis increased 16.1%. Specifically, technology and communication costs increased primarily due to higher clearing and data fees as a result of higher credit AllTrade volumes and streaming U.S. Treasury volumes, which continue to grow. In addition, this quarter also saw the continued impact of our previously communicated investments in data strategy and infrastructure. Adjusted general and administrative costs increased primarily due to an increase in travel and entertainment as we recover from the pandemic. Favorable movements in FX resulted in a $2.2 million gain in the third quarter of 2022 versus a $900 thousand gain in the third quarter of 2021.
Professional fees increased 6.4% mainly due to higher legal costs. Slide 14 details capital management and our guidance. First, on our cash position and capital return policy. We ended the third quarter in a strong position, holding $1.1 billion in cash and cash equivalents and free cash flow reached $555 million for the trailing twelve months. We have access to a $500 million revolver that remains undrawn as of quarter end. CapEx and capitalized software development for the quarter was $12.3 million, an increase of 23% year-over-year. We continue to expect capital expenditures and capitalized software to be in the range of $62 million-$68 million for the full year. With this quarter's earnings, the board declared a quarterly dividend of $0.08 per Class A and Class B share. We spent $11.3 million offsetting equity dilution during the quarter.
Specifically, we spent $9 million under our regular share buyback program, leaving $9 million for future deployment as of the end of the quarter. In addition, we withheld $2.3 million in shares to cover payroll tax obligations related to equity compensation. In October, we exhausted our $150 million share repurchase authorization, which expires at year-end. Given our historical philosophy of using share repurchases to offset the impact of our annual equity grants, we will be discussing with our board renewing our buyback program, as well as other typical aspects and strategies within our capital management framework. Turning to other guidance items for 2022. We are now tightening our adjusted expenses to range from $620 million-$640 million, which incorporates the benefits from FX movements mainly related to sterling.
For forecasting purposes, we continue to use an assumed non-GAAP tax rate of 22% for the year. Finally, on slide 15, we've updated our quarterly share count sensitivity for the fourth quarter of 2022 to help you calibrate your models for fluctuations in our share price. Now I'll turn it back to Billy and Lee for concluding remarks.
Thanks, Sara. Following the positive third quarter results, we believe we are on track for another great year at Tradeweb and for our 23rd consecutive year of record revenues. That level of consistent absolute revenue growth speaks to the resilience of our business model and the team remains laser-focused on things in our control, maximizing the power of our network to drive further innovation into the marketplace. While the ongoing FX environment acts as headwinds to the core growth and earnings power of the business, we believe our competitive position has never been stronger, a testament to the impressive talent and network we have at Tradeweb.
With a couple of important month-end trading days left in October, which tend to be our strongest revenue days, we are seeing double-digit volume growth across credit, equities and money markets relative to October 2021. The diversity of our growth remains a theme as we continue to see double-digit average daily volume growth across U.S. high-grade credit, munis, CDS, global ETFs, equity derivatives, repos and retail certificates of deposit. We are seeing record average daily volumes in our muni business. Our IG share is in line with third quarter levels, while high-yield share is stronger than Septe mber levels. I would like to conclude my remarks by thanking our clients for their business and partnership in the quarter. I wanna thank my colleagues for their efforts that contributed to the record quarterly revenues and volumes at Tradeweb.
As I sign off for my last earnings call, I wanna also thank all the investors and sell-side analysts that I have had the great pleasure to meet over the last few years. With that, I'll turn it back to Ashley for your questions.
Thanks, Lee. As a reminder, please limit yourself to one question only. Feel free to hop back in the queue and ask additional questions at the end. Q&A will end at 10:30 A.M. Eastern Time. Operator, you can now take our first question.
Thank you. To ask a question, you need to press star one one on your telephone. Please stand by while we compile the Q&A roster. First question comes from the line of Richard Repetto from Piper Sandler. Your line is open.
Good morning, Lee, Billy and Sara. First, Lee, I just want to congratulate you. You've had a great run. You've been resilient and unflappable. I think I've used that word to describe you before but well-deserved, you know, great run. My question is, what are you gonna do now? Now, my question is actually for Billy and you as well. As you go through this transition, you know, what will be your focus, Billy and what things are you taking from Lee to as really the mantra to lead Tradeweb going forward?
Great question, you know, Rich. You know, thank you for asking. Lee's obviously been great through this transition. I'm looking forward to working with him as Chairman of the board. I would probably be a little bit more emotional and flowery in terms of what I was saying if, like, every analyst in the community plus all of these people weren't dialed in at this exact moment. I'll leave that sentiment between Lee and me kind of closed, you know, closed doors. You know, the groundwork has already obviously begun and we're kinda hitting the ground running. I referenced this in my prepared remarks, Rich. We had an excellent management offsite meeting at the end of the summer. When you have, you know, real engagement, you feel it.
I think that the team is obviously very charged up for the opportunities that lie ahead for the company. My areas of focus, I think, you know, obviously you would understand exceptionally well, it's gonna be, you know, talent development. Both myself and Lee have always kind of historically talked about, like, the power and the importance of the people. We're gonna make sure that, you know, talent development stays first and foremost, as a priority. You know, installing an executive leadership team, you know, from my perspective, deepening our network with partnership and acquisitions, these are like, you know, major priorities. It is obviously, from my perspective, a great moment to have, you know, Tom Pluta on board. He'll be President of the company as of 1 January .
We both Lee and I have a long history and relationship with Tom. He's gonna be an excellent addition to the management team. It's always sort of awkward saying nice things about people while they're kind of looking across from me. Sara has been a, like, absolutely strong partner and an amazing CFO. I feel personally, you know, really good about kinda where we are at this moment in time. To your great question about, like, what I'm going to kinda take from Lee, as much as I can.
You know, at the end of the day, obviously we're all kind of different people and different personalities, so I'm gonna be myself as, you know, as the next CEO of the company in a way that I think will make Lee proud and the company proud and we're gonna move on into this next chapter and succeed and do our best. I appreciate your question, Rich. I think one thing for us to sort of determine is how I'm gonna still participate in your infamous kind of president's panel. You know, maybe Tom and I can kind of arm wrestle and figure out who's gonna be the one that participates in that, 'cause I know that's like a big kind of historic ratings hit. We appreciate your question always, Rich, so thank you.
I think you move up a slide, Billy. Anyway, Lee, great run and congrats. Thank you.
Thanks, Rich. I'm just gonna say something really quickly and that is, I think, you know, the company is in such good hands. I think the investors have a lot to look forward to. This is, you know, under Billy's leadership with Tom joining and Sara being here and the rest of the team, it's incredibly well-positioned. Aside from the, you know, the sort of opportunity of the company, the people who are in place are the same people who've been running this business for decades. You know, Tom's new, Sara's relatively new but I think we are so well-positioned and I'm excited to watch them excel and grow the business and grow as leaders. Thanks for the kind remarks.
Thank you.
Thank you. One moment for our next question. Our next question comes from the line of Kyle Voigt from KBW. Your line is open.
Hi, good morning. Maybe a question for Billy. You know, there's been a sizable buy-side market participant in the U.S. Treasury market that's been very vocal about wanting an all-to-all solution for the market. Can you just talk about the concept of all-to-all in U.S. Treasuries and how you see the market structure potentially changing over time from what is still a relatively bifurcated market structure today?
Yeah, sure. Great question, Kyle. How are you? It's a good question, just like as a quick kind of point of kind of context to make a sort of strong point and kind of an important one. Obviously, the U.S. Treasury market is different than the credit market. You know, it's significantly more electronic. We have the estimates of the government bond market at around 60% versus kind of credit, which is around 45%. I would say kind of more importantly, 80% of the activity in government bonds kind of happens in like seven of the most actively traded issues versus credit, which you know well. Kyle has, I think, like something like 13,000 CUSIPs, right? There's a significant difference between those two businesses. You know, that being said, I think you kind of nailed it in your question.
You know, first of all, the PIMCO kind of. The white paper that they wrote, I think was, like, significantly important. You know, PIMCO is a very influential, very important customer. It was a very thoughtful and very well-written white paper on some liquidity challenges in the government bond market. You know, we're going to be in a way that you would expect, like, exceptionally responsive. I think we have a team literally at PIMCO, kind of as we speak, we're gonna engage with them directly, get their perspective on things. If we were gonna kind of chart out some of, you know, our views on the evolution of it all, I think, you know, there's absolutely an aspect of all-to-all trading that makes sense in the sort of deeper areas of the off-the-run marketplace.
We can also kind of imagine a world, I think, pretty easily, where more and more of the buy side has access to what we describe as the central limit order book world, which is why it's been very important for us from a strategic perspective to be in that business. We feel like we are kind of really well set up around this evolution. You know, there's an interesting kind of back and forth debate on this. I think ultimately, at the end of the day, as we move forward around this, it's important to remember that there's not necessarily at all kind of one trading protocol that fits one marketplace.
We do feel like there's a role potentially for all-to-all trading and government bon ds, just like there's obviously always going to be a significant and sizable role around RFQ trading, request for quote trading, disclosed streaming trading. There are a bunch of very important protocols in the government bond market that will make this a continually vibrant and important marketplace. This is a topic that fits us like a glove and we're gonna play a leadership role around it, I think, in a way that you would expect us to. Thanks very much for the question.
No, thank you.
One moment for our next question. Our next question comes from the line of Craig Siegenthaler from Bank of America. Your line is open.
Hey, good morning, everyone. I don't know if you guys heard but it's Craig Siegenthaler from Bank of America. It cut out on me.
Hi, Craig.
Hey, Craig.
My question is on portfolio trading. What were the major drivers of the sequential decline in international portfolio trading other than FX? Also, can you just put this in the context of the longer-term growth trajectory of portfolio trading adoption outside of the U.S.?
Yeah. I mean, I think portfolio trading is gonna fit really well into that European community and credit. They tend to be very focused on, I think two of the most important kind of principles around portfolio trading, you know, which is, from our perspective, information leakage and certainty of execution. The feeling that we have is that it's gonna become more and more of a risk transfer trading tool for those European customers. There's gonna be kinda ebbs and flows on a month-to-month basis around some of these market share numbers. General feeling, obviously, is that portfolio trading works better and right now has more, what we would describe as sort of straightforward acceptance in high grade than sort of the less liquid areas of the credit market.
This is a fundamentally important protocol in the credit markets globally and we feel like the European community is generally very supportive of what we're building and where we're arriving with our portfolio trading. Thanks very much for the question.
Craig, I'd just add that obviously, as you alluded to, FX does play a role just in terms of that comparison. Whether you're looking at, you know, the year-over-year period, third quarter to third quarter or nine months, FX, you know, particularly the euro, is down quite a bit.
Thank you. One moment for next question. Our next question comes from the line of Michael Cyprys from Morgan Stanley. Your line is open.
Great. Thanks. Morning. Hey, just curious your perspectives on the SEC's recent proposal for the central clearing of Treasuries. What sort of potential impact could we see in the marketplace? What sort of opportunity do you see in this for Tradeweb? How you might sort of quantify that and what sort of actions might you need to take to best capture the opportunity?
Yeah, it's a great question. You know, it's interesting. I mentioned the PIMCO white paper and I do think it resonated really strongly within the community. It's interesting. They're not a proponent really of central clearing. I mentioned that because you do really get a sort of like interesting kind of debate back and forth around the benefits. Our general perspective is, you know, it's good for our business. You know, in a straightforward way, it reduces our capital requirements. We have learned a bunch of lessons around how central clearing was applied to the global swaps market and how that accelerated the electronification of that market from really sort of a little bit of a negotiated back alley market into this really strong electronified market that exists today. We're proponents of it.
What we would say is, as the first question I got around government bonds was really about the liquidity of the market. We wanna be exceptionally thoughtful that by embracing central clearing, we are not affecting the liquidity of the government bond markets, where there can be a perspective that certain players who are important in the market today would find an expense level too high to be as active participants in a market going forward. We wanna be thoughtful about how this winds up getting applied. We're gonna be kind of heard on this issue, I think, in a way that you would expect us to be heard. We have a lot of credibility, obviously, as the leading, you know, the leading electronic venue in government bonds.
We're gonna come out with our own, I think, strong view. It's gonna take into effect a lot of the nuances that I was kind of mentioning before. General feeling is like it's good for us and we're set up well for it. I think the debate on this will continue for a little while. Thanks for the question.
Thank you. One moment for our next question. Our next question comes from the line of Andrew Bond from Rosenblatt Securities. Your line is open.
Hey, good morning. Following up on not portfolio trading, September was a record month for portfolio trading at Tradeweb despite some concerns that higher levels of volatility would limit growth and more volume would shift to all-to-all protocols. Do you think portfolio trading can continue to grow meaningfully if markets remain highly volatile or is there a limit to some of the growth in this environment?
No, it's gonna keep growing, right? It's getting more applied for sure into the IG world, into the investment-grade world than high yield, which, you know, still has, I think, some of the history and some of the behavior habits around the all-to-all kind of trading style. I think the one thing that we have, I think, decided in a pretty strong way is that the all-to-all environment is not necessarily the most conducive environment for real kind of risk transfer trades. One of the things I think that makes us, you know, really strongly positive on the value of portfolio trading is the way that portfolio trading has, from our perspective, become a real risk transfer mechanic or mechanism around that and that's important. We feel like it behaves really well in volatile markets.
Right now, it's kind of being applied more to IG than high yield. Some of that is behavior. As you know, the behavior change kind of takes time. I think some of the behavior around high yield still goes into that all-to-all environment, if that makes sense. Thanks for the question.
Thank you.
Thank you. One moment for our next question. Our next question comes from the line of Alex Blostein from Goldman Sachs. Your line is open.
Hey, good morning, guys. Thanks for taking the question. Hey, Billy, I wanted to spend a couple of minutes maybe on some of the competitive dynamics in credit trading and really just kind of maybe zoning in on some of the convergence we're seeing between different protocols that you and MarketAxess are starting to zone in on. On the one hand, you guys have been leading in portfolio trading. MarketAxess now doing more portfolio trading, as you guys are pushing more aggressively into RFQ with some of the innovation you mentioned, as well as all-to-all. As these two kind of Venn diagrams start to converge, what are your views on pricing? Is it reasonable to think we'll start to see more pricing pressure in the space or really more competitive dynamics on pricing, I guess?
Just a reminder, how do you guys compare to the incumbent in the space in terms of apples to apples kind of comparison on pricing, whether or not you guys will be willing to kind of lean into that a little bit more?
You know, it's a great question, Alex. You know, thanks very much. I kind of have made this point before, you know, pretty strongly that, you know, as we have entered into the credit space and shown our ability to really compete in the credit space at a very high level, we've never kind of led with price. You know, I think that's an important thing. We've led with innovations and creating efficiencies, you know, for our clients. We feel in a very strong way that the market is really supportive and wants kind of this competition in a way that you just described because they benefited from it. I've always been, I think you know, in a, in a very straightforward way, like complimentary of MarketAxess from the perspective of having gotten, you know, a lot of things right.
I think they were, you know, a little bit late around portfolio trading and have done a very good job recently of understanding how important that protocol is and doing better in it. One of the things for sure that we found is, as we've delivered innovations into our customers, specifically speaking around portfolio trading or around Net Spotting and Net Hedging, we're able to get more of their kind of traditional RFQ business as a consequence. In the exact way that you described, I do think there's some convergence of where we're all competing. You know, that being said, again, high level and in a really important way, the market really does want to support and have this kind of competition in the space.
As you know exceptionally well, we grew up competing in a lot of the markets that we're in, Alex, with Bloomberg from essentially day one. That competitive dynamic has kind of existed for us always and I think it makes, you know, both firms better and I think the clients wind up winning as we continue to innovate. I don't know, Sara, if you wanna add any comment around kind of pricing.
Yeah. I would say, look, we were a newer entrant into the credit space. I think generally it's hard to do apples to apples but generally apples to apples, I think our pricing is a little bit lower. But as Billy said, I think the more important point is we compete through innovation and we compete differently. You know, our business mix in terms of different client channels is also a differentiator between retail, institutional and wholesale.
Thanks for the question, Alex. Good to hear your voice.
Thank you. One moment for our next question. Our next question comes from the line of Daniel Fannon from Jefferies. Your line is open.
Thanks. Good morning. I had a question on high yields and just kind of the market share dynamics, more recently. Can we ascribe it more to some of the volatility? Just trying to think about the longer term trajectory of, as you think about market share, is there something structurally different about this market and your ability to kind of grow share over time versus, say, high grade? Talk a little bit more specifically about some of the nearer term dynamics.
I think, you know, I think it's a combination really of sort of volatility in the market. It's a good question. I think it's a combination of sort of volatility in the market at a moment in time, plus the reality that high yield tends to be, you know, ultimately less liquid, that tends to have strong behavior in that marketplace around all-to-all trading. Our network has come a long way from when we were first answering these questions from you guys, thoughtful questions from you guys back in March of 2020, around our high yield responder network. But at the end of the day, MarketAxess still has the sort of default liquidity in that high yield network. As that market kind of stays all to all a little bit, they wind up winning.
That being said, we had an excellent, you know, month so far, in our market share around, portfolio trading, specifically speaking in high yield. These things kind of have their own life form and can kind of turn pretty quickly. We're really strong on selling the benefits of portfolio trading to our clients, around maintaining their relationship with the market makers, the benefits around cost, the benefits around information leakage, minimizing information leakage and, the benefit around, executable trading, on one level. We feel really good that that message continues to resonate. At the end of the day, that's kind of what we care about. I think we're well positioned there.
Thank you. One moment for our next question. Our next question comes from the line of Gautam Sawant from Credit Suisse. Your line is open.
Hey, good morning and thank you for taking my question. Can you please share your perspective on the impact the rise of fixed income ETFs is having on industry market structure and fixed income turnover velocity? Can you touch upon your future growth initiatives within the ETF marketplace and how the Tradeweb platform is positioned relative to competitors?
I mean, I think in the most straightforward way, right, we have a, you know, exceptionally strong ETF business both in the U.S. and Europe. We have this great global ETF business that has had exceptional success throughout this year and specifically speaking over the last quarter. One of the things I think that's really important is that the, you know, traditional ETF market makers are playing a larger and larger role around market making in credit. We do feel like that has given us a little bit of an advantage as we've continued to kind of march forward in our credit offering, as these significant kind of ETF players also become standalone important market makers in credit.
That kind of helps kind of round out or kind of put the pieces of the puzzle together for us around ETFs and credit. Our perspective is this ETF business is gonna continue to grow. It's obviously benefited in a very strong way from the volatility in the equity markets and we have a really strong team globally around our ETF business. We feel really good about how we are positioned in ETFs and also feel really good about how that has given us an edge in terms of how we've built out our credit business as well. Thank you. Thanks a lot for the question.
One moment for our next question. Our next question comes from the line of Alex Kramm from UBS. Your line is open.
Yeah. Hey, good morning, everyone. Not to be too overly focused on the monthly minutiae but when you gave your update for October, I know with a couple of days left, the one business that was noticeably absent, which is your biggest business, is interest rate swaps. Just trying to get a feel of what's happening there. I mean, if you look at some of the data that we track intra-month, it looks like that business is actually down year-over-year. Some of this may be FX but after seeing a nice trajectory during the third quarter, we're kind of hoping 4Q could kind of reaccelerate here. Just wondering if anything is weighing on this and what needs to change for that business to kind of accelerate to historical growth rates again. Thanks.
No. Hey, Alex. It's Billy. You know, you're allowed to get into the minutiae in any way that you want. We really appreciate the question. Like, the European swap story for us has been like a significant success, right? It's been really kind of the lead horse for us in our entire rates complex. To your exact and specific question, it's taking. You know, the European swaps market's taking a little breather, you know, in these few weeks in October. So the volumes are down a little bit. I think it's been through obviously, you know, significant amount of volatility. Some of the players who have been, like, actively involved, you know, throughout this year are taking a little bit of a half a step back.
Big picture, we feel exceptionally strong about how we're positioned in that business. We have built out really important protocols around request for quote, which have landed squarely with our most important hedge fund clients in Europe. There's going to be a continued sort of onboarding of clients into the MiFID world in Europe and we feel really strongly that we're positioned, you know, very well around our European swaps business going forward. You're correctly identifying something but I wouldn't read too much into it, Alex. Completely, you know, appreciate your question and your attention to detail. Thank you.
Sir, will you be taking more questions at this time?
Yeah. We'll take two more.
Okay. One moment for another question. Our next question comes from the line of Ken Worthington from JPMorgan. Your line is open.
Hi. Thanks for squeezing me in. You talked a lot about innovation and I think Lee kicked off with listen to your clients, build products, connect the dots. What happens to innovation at Tradeweb in more challenging or more extreme environments like we've seen in recent months and quarters? Do you get more actual ideas and more opportunity to execute? Is this really the time when innovation takes off or is it the opposite and things start to stall because you're too busy? And then you highlighted swaps and credit as the backbone for growth and EM and munis is having a lot of opportunities. Where does new innovation really need to be for you to deliver on these growth opportunities?
Good question, Ken. You know, you in a very sort of reasonable way, in a way that you're describing, you have to be sort of aware of the environment. I'm gonna say that in a very clear way. You have to have kind of good core awareness. When you know, to make an obvious point, you know, when the long bond is up a point or two points, you have to be a little bit careful around your 3:30 P.M. meeting that is scheduled, right? We thrive on these kind of, you know, sort of one-on-one meetings and this sort of, like, approach around the whitepaper and let's ideate and let's solve things. You have to be aware, to your question, around the moment in time in the marketplace and I think we're really good at that.
We're really good at understanding what our clients are going through and what their lives, what their business lives are like. That being said, in a really interesting way to your question, I think the stakes get really high around the innovations, right? A tweak here or a tweak there around how portfolio trading works or a tweak around the response time around requests for markets that I talked about around European swaps, these have, like, real market and real life consequences at a point in time where the markets are extremely volatile and challenging. I think the stakes get higher. I think our credibility of kind of having been that partner around innovation, I think matters more when the markets get more challenging. Our pipeline is as strong as ever. The idea generation kind of continues.
You are right. You have to be kind of aware that there are moments where, you know, a Friday morning is free and then all of a sudden it's not free. You have to pick and choose your spots when you're dealing with and talking with high-level market professionals. The team's really good at that and really good at understanding that. That's how I would kind of understand. That's how I would describe that point to you.
Can I just chime in? I think kind of a complement to that mindset, which is we have a really strong track record of continuing to make investments in all market conditions. You mentioned EM and muni and I think it's not a need to invest in those initiatives. That's just our core philosophy on innovation and growth. We've been able to do that. This year is a really good example. We've been able to invest in these new areas, in our technology, in our data and infrastructure, while also delivering margin improvement.
Part of the beauty of the operating model is that strategy of constantly being close to your clients to innovate in the near term around acute volatility, in the long term around having fundamental growth drivers is something that we've had a really good, strong track record on.
Thank you.
Thanks for the question, Ken.
One moment for our next question. Our next question comes from the line of Chris Allen from Citi. Your line is open.
Morning, everyone and thanks for taking my question. Maybe just following up on Sara's comments around delivering margin improvement. Can you maybe talk about your ability to manage expenses and provide some detail on some of the puts and takes related to FX, travel, entertainment, inflation and variable comp, moving forward?
Sure. Thanks. That's a great question. I think at the highest level, I think a really helpful way to think about it in sort of a rule of thumb, about 50% of our overall expense base is either variable or discretionary. But the highest level, we have a real amount of flexibility in terms of how we manage our expenses through various market conditions and be able to still deliver margin expansion. Obviously, we've talked about a very consistent philosophy of balancing that margin expansion with driving and investing in long-term revenue growth. You asked specifically, which is like a more near-term question around puts and takes, you know and where we're managing inflation. I think this year is a really good, you know, sample set. Inflation for us really comes down to people costs.
You know, the vast majority of our expense base is people and we feel like we've done a really effective job in managing those trends while still investing in hiring and being able to compete really effectively for talent while still delivering on the margins. We expect to continue to do that. The last piece is FX, which is obviously not completely in our control. I wish it was. FX has been a headwind. You know, this quarter is somewhat unprecedented and we put in the earnings deck, I think it's page 11, to break it out a little bit in terms of how FX moves on the revenue line. On the expense line, roughly the rule of thumb there is about 15% of that expense base is correlated to sterling.
Sterling, if you looked at this quarter, is down 14% versus the dollar. That has a positive impact on the quarter. Overall, in that same time period, euro, which is much more of a correlation on revenues, that's a 30% correlation and that's also been a drag. Net-net, you know, FX is diluted to our EBITDA margin. We do have a hedging strategy that dilutes that impact and that volatility quite a bit on the cash flow. But FX, you know, certainly has offset and sort of dampened the expense growth from a reported basis.
Overall, as we view, you know, with, I think, the comments that we've made, we like our flexibility, we like our ability to make consistent and continuous investments to overall make sure that we're making smart decisions that help support that double-digit revenue growth opportunity over the long term. It won't be linear but I think that consistent philosophy has really served us well.
Thank you. One moment for the last question. Our last question comes from the line of Brian Bedell from Deutsche Bank. Your line is open.
Great. Thanks so much for squeezing me in. I appreciate it. Question for Billy. Maybe talk about the interest rate swap market. I mean, that and credit, obviously, you've identified as the two biggest growth areas. You did say the interest rate swap market for Tradeweb is an underappreciated growth story. Maybe just your credit business obviously gets all the hype, given we can see your direct competitor there. Maybe talk about what you see between those two businesses as sort of the better, say, five-year growth opportunity for Tradeweb in particular and why that, you know, why that would be the case for any?
Yeah. I mean, you know, there's an interesting story around interest rate swaps and it's a great question, right? The interest rate swap market historically was sort of the most resistant towards the electronification of markets, kind of any of the markets that we ever got into. Not to bring Lee down memory lane as the call is ending but he remembers that the best. So, you know, part of our success there came with a lot of hard work around behavior change. The other part of our success there came really around playing a leadership role around regulation as that market obviously went electronic around Dodd-Frank in the US and then kind of MiFID in Europe.
I would argue the combination of the dollar swap market and the European swap market are two of the most important markets in the world, in terms of everything that's been happening, you know, in the rates complex, over the past, you know, over the past six months. We feel exceptionally good around how we're positioned kind of competitively in that space and we also feel exceptionally good around the kind of wallet that's historically been attached to that space. We love the fact that our clients are getting more sophisticated using our products like AiEX more frequently and we kind of click, I think, really, really well in that marketplace. Obviously, considering we've had this leadership role in global government bonds, TBA mortgages for a long time. It fits us like a glove.
Our general feeling is this marketplace is gonna continue to be exceptionally important going forward and we're gonna have that leadership role and that's some of the kind of foundation about why we feel very confident there. Thanks a lot for the question, Brian.
Now I turn this call over to Lee Olesky for any closing remarks.
Okay. Yeah, thank you. Let me just say quickly, I really wanted to thank all of the investors and analysts, anyone who's still on the line, for all the support, you know, over the years. Our interactions have always been great. I'm so proud really of the team. I think you can hear it in the remarks today. I feel like I'm going out leaving you in the best possible hands with Billy and Sara and the rest of the team here and Tom, who's still in the room. We're gonna let him talk maybe next time. You know, have a great day. Obviously, if you have any questions, don't hesitate to reach out to Ashley or anyone on the team, Samir. Thanks a lot for joining. Thank you.
This concludes today's conference call. Thank you for participating. You may now disconnect. Everyone, have a great day.
