Good afternoon, everyone. This is Priscilla, welcoming you to the ING 4Q 2022 credit update call. Please note today's conference is being recorded. Before handing this conference call over to Mr. Jaap Kessens, Global Head of Bank Treasury of ING Group, let me first say that today's comments may include forward-looking statements such as statements regarding future developments in our business, expectations for our future financial performance, and any statement not involving a historical fact. Actual results may differ materially from those projected in any forward-looking statement.

Furthermore, nothing in today's comments constitutes an offer to sell or a solicitation of an offer to buy any securities. Good afternoon, Mr. Jaap Kessens. Over to you.
Thank you, operator. Welcome all, and thank you for joining us today for the ING credit update call of the 4Q 2022 figures. My name is Jaap Kessens, and since July, I'm the Group Treasurer of ING Group, but I've been in the bank for the last two decades. Today, I'm here together with Mark Milders, Head of Investor Relations. In this call, we will take you through the high level 4Q 2022 results, ING's capital position and issuance plan for the coming year. At the end of the call, we will have some time for Q&A. Before we get started, I would like to point out that the credit update slides to accompany this call are available for download from our website. After the presentation, we'll be happy to take your questions. With that, let me hand over to Mark.
Thank you very much, Jaap. Good afternoon all. Allow me to take you through a couple of slides. I understand there's another call coming in Frankfurt. Let me take you through some of the slides and some of the highlights of today's result presentation. Starting with Page 2. Again, after two years of pandemic dominating the headlines, 2022 was again a turbulent year with events that we would not have been able to foresee or talk about before that. Primary customer growth, however, if you look at it, even at the low savings rates, that was very successful again in 2022, with more than half a million of new primary customers. You see that our channel, our cheapest channel, the mobile-only, is growing.
End-to-end digitization, as we explained at the investor update, which is a driver of efficiency, is growing. Volume mobilized is the amount of money that we are able to enable our customers to invest in a transition, is growing. On top of that, the hot topic, of course, with the current rate environment and the increases is growing NII and our distribution to shareholders over 2022 of EUR 4.8 billion. Moving on to Slide 5. Our targets, which we communicated at the investor update, we are on track to meet those, especially on the back of improved outlook on interest income. We upgrade our total income growth target from the previous 3% to a new range of 4%-5%. This is based on the CAGR for the period 2021, 2025. It is not linear.
As 2023, we'll see more than 10% increase in total income with the shape of the curve, a lowering of the growth in the outer years coming to a CAGR of 4%-5%. On the cost side, we expect to see some pressure from the full year effect of inflationary pressures, we continue to invest in our business and to execute our strategy. We look to improve our cost income ratio in 2023 and expect to land between 55% and 56%.
Moving to Slide 11, where we highlight our funding profile, which is well known to you, but clearly, the return to positive interest rates in 2022 demonstrates the benefit of our funding profile with a high share of sticky retail deposits and a relative limited dependence on the more volatile wholesale funding. After years of significantly compressed deposit margins, we're now seeing a swift normalization. We're not yet there, as I'm pointing to the middle graph, but we are pleased with the progress. These developments are also visible when we look at total income, which grew by EUR 1 billion in 2022 when correcting for the net TLTRO impact and the Polish mortgage moratorium. On to expenses on Slide 13. Expenses were well contained in a high inflationary environment.
While we continue to invest in our customer experience, our basis for future growth, excluding regulatory costs and incidental items, expenses increased over 2022 by 2.3%, compared to just in the Eurozone already of a larger than 8% inflation. Looking ahead, we expect to see some cost pressure in 2023, and we'll continue to focus on cost control to keep our expenses contained, delivering an improvement of the cost income ratio in 2023 as mentioned. Regulatory expenses came in slightly lower in 2022, and we expect another slight decline in 2023. Note that we will still foresee regulatory costs to decrease by EUR 400 million by 2025 compared to the levels of 2021, which is coming from the finalization of the buildup of the resolution fund and the European DGS.
Skipping quite a few slides to Slide 23 on, for our bank, the important risk section. Again, we reiterate the strength of our loan book, the high quality of our loan book. This quarter included a further release of EUR 112 million Stage 2, mainly related to our Russian exposure, which we reduced again this quarter, and the EUR 46 million release of management overlays for potential impact of second order effects of the current macroeconomic environment. In total, we have built up EUR 453 million in management overlays at the end of 2022. In the graph in the middle, you notice that the Stage 2 ratio increased. In the previous quarter, this was caused by stricter PD backstop methodology.
This quarter, you also see an increase, but that is driven by the denominator as we repaid EUR 29 and a half billion of our TLTRO funding, which was included in credit lending outstandings. Overall, in absolute amount, Stage 2 actually declined. I would like to hand over back to Jaap to take you through the capital and funding.
Thanks, Mark. Maybe turn to the slides on our capital ratio on Slide 26. There we see the bar chart that shows the development of our CET1 ratio, which remains strong at 14.5%. The additional distribution of EUR 1.5 billion as announced on the 3rd of November has been completed. The impact of this was partially offset by the inclusion of EUR 500 million of interim profits and by lower RWA. The RWA decreased by EUR 7.1 billion, mainly reflecting the FX impact on credit RWA caused by the depreciation of the dollar as visible on slide 25. With a 1.9% AT1 ratio and a 3% Tier 2 ratio, ING is fully benefiting from the CET1 capital relief provided by Article 104a.
Turning to Slide 29 on TLAC and MREL. Let me start with TLAC on the left. ING Group meets the end state TLAC requirements with a TLAC ratio of 30.4% of RWA and 9.5% of TLAC leverage. However, for ING, the most constraining requirement is the MREL target as a % of RWA, which we show on the right of this slide. As you can see, we have met our intermediate MREL requirements, while we also amply meet the MREL requirement of 28.71% per the June 2024. This is including the announced CCyB increases. Our current MREL capacity is over EUR 100 billion, with an approximate surplus of EUR 10 billion based on RWA.
Before we open the floor for Q&A, I will elaborate on our issuance plan for 2023 on Slide 30. We have done some pre-funding late last year, allowing us to stay sidelined in our very short issuance window early January, which proved to be a very crowded period. This year, ING plans to issue around EUR 7-EUR 9 billion of Holdco Senior, subject to our balance sheet developments, of course, and this is slightly lower compared to last year, where we issued around EUR 11 billion. The planned Holdco Senior issuance is driven by the refinance of EUR 1.6 billion of our Holdco redemptions in 2023 and of course, potential RWA growth on the back of high risk migration due to the current macroeconomic environment. Building of internal buffers is also playing a role on MREL, taking average volatility and market access into account.
The aim to optimize our MREL stack by replacing the CET1 surplus with Senior Holdco over time is obviously the last target. AT1 and Tier 2, we strive towards optimization of our capital structure. We feel comfortable with the current AT1 ratio of 1.9% and Tier 2 ratio of 3%. Several Tier 2 instruments totaling EUR 3 billion have a call or maturity date coming up in 2023. The first upcoming call date for AT1 instruments is only in April 2024. We expect that covered bond activity through bank and subsidiary will pick up in 2023 to prepare for further TLTRO repayments. We expect to issue EUR 4 billion-EUR 7 billion in secured format from various ING entities. We still see a limited need to issue Opco Senior due to the current overall liquidity position of the bank.
If need be, we will also look at that funding source. I suggest I stop talking now and open the floor for some questions. Operator, back to you.
Thank you. Ladies and gentlemen, if you would like to ask a question, please press star one on your telephone keypad. In the interest of time, we kindly ask each analyst to limit yourself to two questions only. Thank you. Once again, ladies and gentlemen, if you would like to ask a question, please press star one on your telephone keypad. We'll just wait for a moment to allow opportunity for everyone to signal for questions. It appears there is no further questions at this time. I would like to turn the conference back to you for any further instruction. Thank you.
Thank you, operator. I think we've been very clear, so thanks everyone for joining us today and success with your call with Christine Lagarde in Frankfurt. The investor relation team is obviously available for your follow-up questions. Just reach out and obviously have a very nice day. Bye-bye.
Thank you for joining today's call. You may now disconnect.
