Please note that starting 1 January 2020, as per Central Bank regulation, we have begun reporting results applying hyperinflation accounting pursuant to IFRS rule IAS 29. For reasons of comparability, 2020 and 2021 figures have been restated to reflect the accumulated effect of inflation adjustment for each period through 30 September 2021. Now, let me turn the call over to Inés.
Thank you, Belén, and thank you all of you for joining us on our Q3 2021 conference call. Conflicts and drawbacks generated by the COVID-19 pandemic began to cease during the Q3 of 2021, thanks to the progress in vaccine campaigns and decline in cases. Nonetheless, the uncertainty of the current political scenario remains in the middle of an electoral process and definitions to be taken regarding the so necessary economic plan linked to negotiations with International Monetary Fund. BBVA Argentina's operating income in the Q3 of 2021 was the product of an improvement in the net interest and fee income, offset by higher administrative expenses that took place in the quarter. Meanwhile, the bank actively monitors its business, financial conditions, and operating results in the aim of keeping a competitive position to face contextual changes.
Regarding digitalization, our service offering has evolved in such way that by the end of September 2021, digital clients penetration reached 74% from 71% a year back, while that of mobile clients reached 63% from 59% in the same period. Trend aims towards a certain stabilization considering that the pandemic has caused an important shift towards the adoption of digital channels by clients. Lastly, in terms of responsible banking within the context of its compromise with UN Sustainable Development Goals, BBVA Argentina has begun participating in the Consejo Empresario Argentino para el Desarrollo Sostenible, the local division of the World Business Council for Sustainable Development. I will now comment on the bank's Q3 2021 financial results.
BBVA Argentina Q3 2021 net income, including inflation adjustment effects, totaled ARS 3.4 billion, falling 57.1% quarter-over-quarter and 37.6% year-over-year. Quarterly results are mainly explained by greater operating expenses related to higher administrative and personal benefits expenses. The contraction is offset by a better net operating income enhanced by higher net fee income and interest income, in addition to a lower result from the net monetary position. The accumulated net income for the first nine months of 2021 was ARS 14.9 billion, 1.1% above the accumulated net income for the first nine months of 2020, or ARS 14.7 billion.
The accumulated ROE as of the Q3 of 2021 is 14%, while the accumulated ROA is 2.1%. Excluding the effects of the reversal of the provisions on the tax line in connection with the repayment of income tax inflation adjustments for 2017 and 2019 fiscal years for a total of ARS 4.7 billion at current values, the Q1 of 2021 net income would have been ARS 3.6 billion. As of the Q3 of 2021, a lower quarterly fall of 6.7% would have been observed instead of 57.1%.
The accumulated net income for the first nine months, net of the effects of actions of the clarity judgment on the tax plan, including effects in the Q1 of 2021 for ARS 1.4 billion at current values, would have been ARS 9.5 billion, decreasing 35.6% versus the accumulated net income from the first nine months of 2020. This would have meant an accumulated ROE on the Q3 of 2021 of 8.9% and accumulated ROA of 1.4%. In the Q3 of 2021, interest income totaled ARS 52 billion, increasing 9% compared to the Q2 of 2021 and 30.7% compared to the Q3 of 2020.
In the Q3 of 2021, interest income increased above interest expenses, mainly due to a greater position in central bank liquidity bills, also called LELIQs, and higher interest from repo transactions, both explained by a greater liquidity derived from a lower credit demand. Interest expenses totaled ARS 22.8 billion pesos, denoting a 7.9% increase quarter-over-quarter and a 58.2% increase year-over-year. Quarterly growth is described by an increase in checking account expenses, partially offset by lower expenses by UVA adjustment derived from time deposits linked to such indexes due to the lower increase in the UVA index quarter-over-quarter. Interest from time deposits and investment accounts explain 71.5% of interest expenses versus 73.9% on the previous quarter.
Net fee income as of the Q3 of 2021 totaled ARS 6.2 billion, growing 4.3% quarter-over-quarter and 35% year-over-year. In the Q3 of 2021, fee income totaled ARS 10.3 billion, marginally decreasing 0.8% quarter-over-quarter and increasing 8.2% year-over-year. The quarterly decrease is mainly explained by contracting effect against the previous quarter since commercial credit card benefits were recognized in the Q2 of 2021 and offset by fee links to liabilities, the latter impacted by an increase in prices of ATMs and bundled products and a greater activity in the wholesale segment.
Regarding fee expenses, this totaled ARS 4.2 billion, contracting 7.5% quarter-over-quarter and 16.6% year-over-year. Lower expenses are partially explained by lower digital sales expenses in the Q3 of 2021, which have been reclassified to administrative expenses, offset by the positive effect in the Q2 of 2021 of the redemption of miles purchased in 2020 within the LATAM program linked to the foreign exchange rate. During the Q3 of 2021, personal benefits and administrative expenses totaled ARS 16.2 billion, growing 21% or ARS 2.8 billion compared to the Q2 of 2021, and 18.7% or ARS 2.5 billion compared to the Q3 of 2020.
Personal benefits grew 6.2% quarter-over-quarter and 5.6% year-over-year. The quarterly increase is partially explained by an increase in variable compensation and social contributions. As of the Q3 of 2021, administrative expenses increased 37% quarter-over-quarter and 32.4% year-over-year. The quarterly increment is explained by the previously mentioned reclassification of key expenses on digital banks into advertisement expenses and higher cost of service outsourced through the Spanish parent company. The accumulated efficiency ratio as of the Q3 of 2021 was 69.7%, improving versus the 70.1% and deteriorating versus the 62.3% reported in the Q2 of 2021 and the Q3 of 2020 respectively.
The quarterly improvement is explained by higher percentage increase in the denominator income considering monetary position results than the numerator expenses, which has been positively affected by an improvement in net fee income and net interest income. Excluding inflation adjustments considered in the income from the monetary position line item. In the Q3 of 2021, accumulated efficiency ratio would have been 49.7%, deteriorating compared to the 48.5% of the Q2 of 2021, and improving versus the 50.3% in the Q3 of 2020. In terms of activity, private sector loans as of the Q3 of 2021 totaled ARS 339.9 billion, decreasing 2.8% quarter-over-quarter and 13.8% year-over-year.
Loans to the private sector in pesos increased 2.4% in the Q3 of 2021, and decreased 11% year-over-year. During the quarter, growth is especially driven by a 61% increase in overdraft, mainly through corporate clients, and 7.9% in discounted instruments, mainly with SME clients. Loans to the private sector denominated in foreign currency fell 37% quarter-over-quarter and 35.4% year-over-year. Quarterly decrease is mainly explained by a 40.1% fall in pre-financing and financing of exports and a 46.1% fall in other loans. These loans, measured in US dollars, fell 38.9% quarter-over-quarter and 50.2% year-over-year.
The depreciation of the Argentine pesos versus the US dollar was 3% quarter-over-quarter and 22.8% year-over-year. Decline in both retail and commercial portfolios and in the total loan portfolio are mainly explained by the effect of inflation during the Q3 of 2021, which reached 9.3%. In nominal terms, the retail, commercial, and total loans portfolio all increased 8.3%, 3.1%, and 6.5% respectively during the quarter, yet unable to offset the impact of inflation during the same period. BBVA Argentina consolidated market share of private sector loans reached 8.08% as of the Q3 of 2021, from 8.27% a year ago.
In the Q3 of 2021, total loans to deposit ratio reached 54.5% from 65.5% a year ago. In the Q3 of 2021, NPL ratio reached 2.54% compared to the 2.49% recorded in the Q2 of 2021. The increase is mainly explained by the subtle increase in retail non-performing loans, given the unification in non-performing loans grace periods, in addition to a reduction both in total retail and commercial portfolios. The coverage ratio was 181.66% in the Q3 of 2021 versus the 187.89% recorded in the Q2 of 2021.
The change in the ratio reflects the greater reduction in allowances over the contraction in the total non-performing loan portfolio, mainly due to the update in macroeconomic projections used in impairment loss models, enhanced by the effect of inflation adjustments from previous quarters. Cost of risk reached 2.8% as of the Q3 of 2021, higher than the Q2 of 2021, 2.61%. This is mainly explained by the greater reduction in the loan portfolio, in contrast to the increase in loan loss allowances in real terms. The increase in write-off is explained by the unification of non-performing loans deferral linked to the measures taken by the central bank during the pandemic, mainly related to credit cards.
In the Q3 of 2021, exposure to the public sector, excluding central bank instruments, reached 6.9% from the 6.5% recorded in the previous quarter. On the funding side, as of the Q3 of 2021, total deposits reached ARS 630.8 billion, declining 5.2% or ARS 34.9 billion quarter-over-quarter, and increasing 3.5% or ARS 21.5 billion year-over-year. Private non-financial sector deposits in the Q3 of 2021 totaled ARS 620.4 billion, decreasing 5.6% quarter-over-quarter, and increasing 3.5% year-over-year.
Private non-financial sector deposits in pesos totaled ARS 455 billion, falling 5.8% compared to the Q2 of 2021, and increasing 6.8% compared to the Q3 of 2020. The quarterly decrease is mainly affected by the decline in sight deposits, especially checking accounts, interest-bearing, and savings accounts. This was partially offset by a 16% increase in investment accounts. Private non-financial sector deposits in foreign currency expressed in pesos fell 65.1% quarter-over-quarter and 4.6% year-over-year. Measured in U.S. dollars, these deposits fell 8% quarter-over-quarter and 26.4% year-over-year.
As of the Q3 of 2021, the bank's transactional deposits, checking accounts and saving accounts represented 63% of total non-financial private deposits, totaling ARS 391 billion versus 65.4% in the Q2 of 2021. The bank's consolidated market share of private deposits reached 7.02% as of the Q3 of 2021 from 7.41% a year ago. In terms of capitalization, BBVA Argentina continues to show strong solvency indicators in the Q3 of 2021. Capital ratio reached 23.5%. Tier 1 ratio was 22.9%, and capital excess over regulatory requirements was ARS 88.5 billion or 187.7%. The bank's aim is to make the best use of this excess capital.
The bank's liquidity ratio in pesos and dollars remained healthy at 72.2% and 91.5% of total deposits as of 30 September respectively. Lastly, on 3 November 2021, the shareholders meeting approved the distribution of cash dividends in the amount of ARS 6.5 billion. The distribution of the dividend is subject to the central bank's prior authorization, which has not been granted yet, and is suspended until 31 December 2021. The total amount of accumulated cash dividends pending distribution is ARS 28 billion, considering dividends of ARS 14.5 billion for 2019 results and ARS 13.5 billion for 2020 results.
