Mike Santomassimo
Chief Financial Officer at Wells Fargo & Company
Thank you, Charlie, and good morning everyone. Net income for the third-quarter was $5.8 billion or $1.48 per diluted common share both up from the second-quarter a year-ago. Our third-quarter results included $349 million or $0.09 per share of discrete tax benefits related to the resolution of prior-period tax matters. Turning to capital and liquidity on slide 3. Our CET1 ratio increased to 11% in the third-quarter, 2.1% points above our new regulatory minimum plus buffers, effective on October first. This was up from 10.7% in the second quarter as higher earnings to be approximately 14 basis-point benefit from the sale of certain private-equity investments and lower-risk weighted assets were only partially offset by share repurchases, and dividends.
During the third-quarter, we repurchased $1.5 billion in common stock. Our strong capital levels position us well for the anticipated increases related to the Basel III Endgame proposal released in the third-quarter. Based on where we end the quarter, we estimate that our CET1 ratio would be 50 basis-points above the fully phased in and require minimum if the proposed rules implemented as written after factoring the growth in RWAs and the resulting decline in our stress capital buffer as well as the impact of the new G-SIB buffer calculation changes. Importantly, this is an early estimate subject to change and is before any actions we may take to mitigate the impact of the new rules.
Looking-forward, we expect to continue to have capacity to increase our CET1 ratio while we plan to continue to repurchase shares as we wait for the capital rules to finalize. Turning to credit quality on slide five. As we expected, net loan charge-offs continued to increase, up 4 basis points from the second quarter to 36 basis points of average loans. Commercial net loan charge-offs declined modestly from the second quarter to 13 basis points of average loans, as lower losses in our commercial and industrial portfolio were partially offset by $14 million of higher losses in commercial real estate. We had $32.2 billion of office loans, down 3% from the second quarter, which represented 3% of our total loans outstanding.
Vacancy rates continue to be high and the office market remains weak. Our CRE teams continue to focus on monitoring and derisking the portfolio, which includes reducing exposures. As we highlighted in the past, each property situation is different and there are many variables that can determine performance, which is why we regularly review this portfolio. As expected, consumer net loan charge-offs continued to increase and were up $98 million in the second quarter to 67 basis points of average loans.
Residential mortgage loans continued to have net recoveries, while our other consumer portfolios all have higher losses with the largest increase in our auto portfolio, which was up from the second quarter seasonal lows. Non-performing assets increased 17% in the second quarter as growth in commercial real estate non-accrual loans more than offset the decline in commercial and industrial, as well as modest declines across all consumer portfolios. The decline in commercial and industrial non-accrual loans was primarily due to pay offs and pay downs, which is a good reminder that the resolution of non-performing assets doesn't always result in charge offs.
The increase in commercial real estate non-accrual loans was driven by a $1.3 billion increase in the office non-accrual loan. Moving to Slide 6. Our allowance for credit losses increased to $333 million in the third quarter primarily for commercial real estate office loans as well as for higher credit card loan balances which was partially offset by a lower allowance for auto loans. Since the composition of our office portfolio is relatively consistent with what we shared with you in the past few quarters we did not include a separate commercial real estate slide this quarter. However, we did update the table showing the allowance for credit losses coverage ratio for commercial real estate, including the breakdown of the office portfolio. We have not seen significant increases in charge-offs in our commercial real estate office portfolio yet. However, we do expect higher losses over-time and we continue to increase the coverage ratio in our commercial -- in our CIB commercial real estate office portfolio from 8.8% at the end of the second quarter to 10.8% at the end of the third quarter. On Slide 7, we highlight loans and deposits. Average loans were down modestly from both the second quarter and a year ago. While we continued to have good growth in credit card loans from the second quarter, most other portfolios declined.
I'll highlight specific drivers when discussing our operating segment results. Average loan yields increased to 195 basis points from a year ago and 24 basis points from the second quarter due to the higher interest rate environment. Average deposits declined 5% from a year ago, predominantly driven by deposit outflows in our Consumer and Wealth businesses, reflecting continued consumer spending and customers reallocating cash into higher-yielding alternatives. Average deposits also declined in Commercial Banking, while they stabilized in corporate and investment banking. As expected, our average deposit costs continued to increase, up 23 basis points from the second quarter to 136 basis points with higher deposit costs across all operating segments in response to rising interest rates.
However, the pace of the increase has slowed and our percentage of average non-interest-bearing deposits decreased modestly from the second quarter to 29%, but remained above pre-pandemic levels. Turning to net interest income on Slide 8. Third quarter net interest income was $13.1 billion, up 8% from a year ago as we continued to benefit from the impact of higher rates. The $58 million decline from the second quarter was due to lower average deposit balances, partially offset by one additional day in the quarter and the impact of higher interest rates. Last quarter, we increased our expectations for full year 2023 net interest income growth to approximately 14% compared with 2022, which was up from our expectation of 10% growth at the beginning of the year.
We now expect full-year 2023 net interest income growth to grow by approximately 16% compared with 2022, with the fourth quarter 2023 net interest income expected to be approximately $12.7 billion. We expect a decline in net interest income in the fourth quarter is primarily driven by our assumption for additional deposit outflows and migration from non-interest-bearing to interest-bearing deposits, as well as continued deposit repricing, including continued competitive pricing on commercial deposits.
Turning to expenses on Slide 9. Non-interest expense declined from a year ago, driven by lower operating losses and increased 1% in the second quarter driven by higher operating losses, severance expense, and revenue-related comp. Last quarter we updated our expectations for full-year 2023 non-interest expense, excluding operating losses to approximately $51 billion. We now expect it to be approximately $51.5 billion, or approximately $12.6 billion in fourth quarter. The increase reflects additional severance and other one-time costs, revenue-related compensation and some lags and realized inefficiency [indecipherable].
We reduced headcount every quarter since the third quarter of 2020, it was down 3% in the second quarter and 5% from a year ago. We believe we still have additional opportunities to reduce headcount and attrition has remained low, which will likely result in additional severance expenses for actions in 2024. We are working through our efficiency plans now as part of the budget process. Additionally, the FDIC deposit special assessment related to the events from earlier in the year is finalized in the fourth quarter, it would increase our expected fourth quarter expenses.
And finally, as a reminder, we have outstanding litigation, regulatory, and customer remediation matters that could impact operating results.
Turning to our operating segments, starting with consumer banking and lending on Slide 10. Consumer, small and business Banking revenue increased 7% from a year ago, as higher net interest income, driven by the impact of higher interest rates was partially offset by lower deposit-related fees, driven by the overdraft policy changes we rolled out last year. Charlie highlighted the investments we're making in our Chicago branch network, we're also making investments in refurbishing branches across our existing network.
Additionally, we are bringing our digital onboarding experience through our branches, creating a fast and easy experience for our customers. At the same time, we have reduced our whole number of branches by 6% from year ago. Home lending revenue declined 14% from a year ago due to a decline in mortgage banking income, driven by lower originations and servicing income, which included the impact of sales and mortgage servicing rights. We continue to reduce headcount in home lending in the third quarter, down 37% from a year ago, and we expect staffing levels will continue to decline. Credit card revenue increased 2% from a year ago due to higher loan balances, partially offset by introductory promotional rates and higher credit card rewards expenses.
Payment rates have been relatively stable over the past year and remained above pre-pandemic levels. New account growth continued to be strong, up 22%[phonetic] from a year ago, reflecting the continued success of our new products and increased marketing. Importantly, the quality of the new accounts continued to be better than what we were booking historically, while the majority of new cards were to existing Wells Fargo customers, we are increasingly attracting more customers that are new to Wells Fargo. Auto revenue declined 15% from a year ago, driven by continued loan spread compression and lower loan balances.
Personal lending revenues up 14% from a year ago due to higher loan balances. Turning to some key business drivers on Slide 11. Mortgage originations declined 70% from a year ago and 18% in the second quarter. We continued to make progress on strategic plans we announced earlier this year, including focusing on serving Wells Fargo Bank customers as well as borrowers in minority communities. We did not originate or fund any corresponding mortgages in the third quarter. The size of our auto portfolio has declined for six consecutive quarters and balances were down 9% at the end of the third quarter compared to a year ago.
Origination volume declined 24% from a year ago, reflecting credit-tightening actions as well as continued price competition. Our origination mix continued to shift towards higher FICO scores, reflecting the credit-tightening actions we've taken over the past year. Debit card spend increased 2% from a year ago, with growth in those categories offsetting clients in fuel, home improvement, and travel. Credit card spending continues to be strong, it was up 15% from a year ago, all categories grew from a year -- a year ago, including fuel, which rebounded after declining in the second quarter.
Turning to commercial banking results on Slide 12, middle market banking revenue increased 23% from a year ago due to the impact of higher interest rates and higher loan balances. Asset-based lending and leasing revenue increased 3% year-over-year due to higher loan balances as well as higher revenue from renewable energy investments. Loan balances were up 7% in the third quarter compared to a year ago, driven by growth in asset-based lending and leasing. Average loans were down 1% in the second quarter due to declines in middle-market banking. After the increase in the first half of the year, revolver utilization rates declined in the third quarter to level -- to levels similar to a year ago.
Turning to corporate investment banking on Slide 13, banking revenue increased 20% from a year ago, driven by higher lending revenue, stronger treasury management results, reflecting the impact of higher interest rates, and higher investment banking revenue, reflecting increased activity across all products. As Charlie highlighted, we continued to hire experienced bankers helping us deliver for our clients and positioning us well when markets improve. Commercial real estate revenue grew 14% from a year ago, reflecting the impact of higher interest rates, and higher revenue in our loans and housing business, partially offset by lower loan and deposit balances.
Markets revenue increased 33% from a year ago, driven by higher revenue in structured products, equities, credit products, and foreign exchange. We've had strong trading results for three consecutive quarters, as we benefited from market volatility and the investments we've made in technology and talent to grow this business. Average loans were down 5% from a year ago, driven by Banking, reflecting a combination of slower demand, payoffs, and modestly lower line utilization, average loan balances were stable with the second quarter. On Slide 14, Wealth and Investment Management revenue increased 1% compared to a year ago, driven by higher asset-based fees due to the increased market valuations.
Net interest income declined from a year ago, driven by lower deposit balances as customers continued to reallocate cash into higher-yielding alternatives as well as lower loan balances. While average deposits were down compared with both the second quarter and a year ago, the pace of decline slowed in the third quarter. As a reminder, the majority has been -- Wealth and Investment Management advisory assets were priced at the beginning of the quarter so third quarter results reflected market valuations as of July 1st, which were higher from a year ago. Asset-based fees in the fourth quarter will reflect market valuations as of October 1st, which were also higher from a year ago, but were lower from the third quarter pricing date.
Average loans were down 4% from a year ago, primarily due to a decline in securities-based lending. Slide 15 highlights our Corporate results. This segment includes venture capital and private equity investments, including investments in funds that we sold in the third quarter. The sale had a nominal impact on the third quarter net income. Revenue declined $345 million from the year ago, reflecting assumption changes related to the valuation of our B2B common stock exposure as well as lower venture capital revenue.
In summary, our results in the third quarter reflect a continued improvement in our financial performance. During the first nine months of this year, we had strong growth in revenue, pre-tax provision profit and diluted earnings per share compared to a year ago. As expected, our net charge-offs have continued to slowly increase from historical lows and we increased our allowance for credit losses by over $1.9 billion this year, primarily for CRE office loans and higher credit card loan balances. We are closely monitoring our portfolios and taking credit-tightening actions where we believe are appropriate. Our capital levels have increased and we expect to continue to return excess capital to shareholders. We will now take your questions.
