Bank of America (BAC) Q3 2026 Earnings: NII Up 8%, Operating Leverage Turns Negative

Summary
Bank of America's Q3 2026 NII rose 8% and 2027 guidance is 8% or more, but a $1.2 billion penalty and higher costs turned operating leverage negative and cut CET1 to 10.9%.
Bank of America's third-quarter 2026 earnings showed stronger net interest income but negative operating leverage. The company reported results for the quarter ended September 30, 2026 in an 8-K earnings release on October 14, 2026: interest income from loans and deposits kept improving, while a regulatory penalty and higher costs weakened how much revenue turned into profit [1].
Going into the quarter, four questions mattered. Could net interest income (NII) growth land at the upper end of the company's 6% to 8% full-year guidance, and could full-year operating leverage reach the 300 to 400 basis points management had guided to [2]? How much of the fee revenue was repeatable? Could capital keep supporting buybacks of about $6 billion a quarter while loans grew? This quarter confirmed the NII outlook, trading and underwriting revenue fell back, operating leverage turned negative and the common equity tier 1 (CET1) ratio dropped 37 basis points. The way the bank makes money has not changed. What changed are the parameters: NII is growing faster, the expense base now carries compliance remediation costs and the capital cushion is smaller.
Bank of America reports through four segments: Consumer Banking, Global Wealth and Investment Management, Global Banking and Global Markets [3]. It earns money mainly from the spread between loans and deposits, from fees on client assets it manages, and from fees and trading revenue in its corporate and institutional businesses.
Operating leverage turned negative, and costs beyond the penalty did not fall with revenue
Expenses grew much faster than revenue in the third quarter. Revenue was $30.119 billion, up 3.2% from a year earlier, while noninterest expense was $19.722 billion, up 13.8%. The efficiency ratio rose to 65.48% from 58.72% in the second quarter [4]. Expenses included a $1.2 billion non-tax-deductible civil money penalty tied to regulatory consent orders on the company's anti-money laundering and economic sanctions compliance programs [1].
Operating leverage was still negative after excluding the penalty. Adjusted noninterest expense was about $18.5 billion, up about 7% from a year earlier [5]. Management attributed the increase to wealth management incentives, transaction costs in the equities business and investment in technology and brand [6]. Headcount was 209,911, down about 3,500 from a year earlier [4], which management attributed to automation and AI.
The penalty reduced earnings per share by $0.17 [1]. Management expects to return to positive operating leverage in the fourth quarter and kept its medium-term target of 200 to 300 basis points, but it did not repeat the full-year guidance of 300 to 400 basis points [6]. Excluding the penalty, operating leverage for the first nine months was about 1.9 percentage points. Management said remediation costs of several hundred million dollars a quarter are already in the run-rate expense base; it has not said when they will decline.
Trading and investment banking revenue fell from second-quarter highs
Noninterest income fell 13% from the second quarter, showing that a large part of the earlier growth was not repeatable. It was $13.509 billion in the third quarter, compared with $15.561 billion in the second quarter. Investment banking fees were $1.799 billion, down 11% year over year [4]. Sales and trading revenue excluding the DVA accounting adjustment was $5.055 billion, compared with $7.155 billion in the second quarter, and down 5% year over year [1]. Management attributed the decline in fixed income to slower client activity after interest rates rose about 85 basis points in the quarter [6].
Asset management fees, the repeatable part of fee income, kept growing. They were $4.630 billion, up 17% year over year, and assets under management had net inflows of about $20 billion in the quarter [4]. That growth limited the year-over-year decline in noninterest income to about $0.3 billion. About half of the growth in assets under management came from higher market values, so this support would weaken if markets fell.
Progress: roughly 8% NII growth confirmed
Net interest income rose sequentially for the second quarter in a row. Third-quarter NII was $16.610 billion, up 8% from a year earlier, and net interest yield was 2.16%, 8 basis points higher than in the second quarter [4]. Average loans grew 6% year over year and have grown sequentially for 10 consecutive quarters [1].
Management reaffirmed NII growth of about 8% for 2026 and expects growth of 8% or more in 2027. That outlook assumes three more 25 basis point rate increases through June 2027 [6]. The rate paid on Consumer Banking deposits rose to 0.51% from 0.48% [5], so deposit costs during a rate-hiking cycle still need to be tested.
The capital cushion narrowed while credit kept improving
The CET1 ratio fell to 10.9% from 11.2%, while buybacks stayed at $6 billion [5]. Risk-weighted assets rose by about $31.7 billion and CET1 capital fell by about $3.2 billion [4]. Management said the penalty pushed earnings below shareholder distributions and that about $1.8 billion of securities losses from higher rates also reduced capital. CET1 remains about 90 basis points above the regulatory minimum, and management said buyback plans depend on final capital rules [6].
Credit moved the other way. Net charge-offs were $1.349 billion, and the net charge-off ratio fell to 0.44% from 0.47% in the second quarter. Reservable criticized commercial exposure fell to $19.906 billion, its second straight quarterly decline [4].
Conclusion
The third quarter strengthened Bank of America's growth engine and weakened profit conversion and capital room. Loan and deposit growth support the NII improvement, but the 2027 outlook depends on the rate-hike assumption. The penalty will not recur, yet expenses excluding it still grew faster than revenue, so whether operating leverage turns positive in the fourth quarter is the direct test of cost discipline. Final capital rules will determine the CET1 cushion and room for buybacks.
