Big Banks Just Made a Lot More Money. Here's Why It Might Not Last

JPMorgan and Goldman Sachs earned higher profit on Oct. 13, 2026, to start earnings season for the biggest U.S. banks. The Wall Street Journal Fees from Wall Street trading and deals drove the beat. Income from loans hit a new high. Higher rates still made the outlook less clear.

Analysts already expected a jump. In an Oct. 8 preview on rates, deals and outlook, they thought earnings for the largest U.S. banks would rise up to 20% from a year ago. The focus was JPMorgan, Goldman Sachs, Citigroup and Wells Fargo, the group that usually reports first. Reuters

Net interest income does the heavy lifting

Three of the biggest U.S. banks set a record for loan profits in the third quarter of 2026. Bloomberg Think of it like a shop markup. Banks collect interest on loans and pay interest to savers. The gap is their loan profit. Higher rates widened that gap.

Bank of America expected its full-year 2026 loan profit to grow at the top end of its 6% to 8% forecast range. What it pays savers had not caught up with higher earnings on loans and bonds. Reuters

Rates are not moving down in a straight line. Australia's central bank raised rates three times this year to 4.35% through July. That was then the highest among big rich economies. Reuters

The broader context here is that higher-for-longer rates help and hurt. They help banks earn more when old loans reset at higher rates. They hurt because banks must fight harder for deposits, face paper losses on bonds, and see some borrowers struggle to pay. That tradeoff affects shareholder returns, payouts, and how much banks can save for bad loans while still building capital.

Trading and the investment banking rebound

Worldwide fees for advising on deals and selling stocks and bonds reached $61.4 billion in the first half of 2026. That was up 24% from a year earlier, according to Dealogic data. That built a pipeline of work heading into the third quarter. Stock and bond trading also gained from swings around the rate outlook. Reuters

U.S. News reported on Oct. 13 that the biggest banks had another strong quarter as people kept paying bills and businesses spent on AI. That AI spending supported cash handling, use of credit lines, and stock and bond sales. Most of that work goes to the largest banks. U.S. News

The broader context here is about what lasts. When trading, client work and deal fees fire together, profit before setting aside for bad loans can cover weak spots. The question for the fourth quarter is how many announced deals close and pay fees, the risk of holding loans for buyouts, and whether gains come from many deals or just a few giant ones.

Credit holding, guidance cautious

The broader context here is that record loan profit late in a high-rate cycle is good news and a warning. It shows banks kept deposit costs in check. It also warns that extra profit increasingly comes from stressed borrowers, not cheap deposits. For savers, that can mean better savings rates if banks compete. For borrowers, it can mean tighter terms. Watch late payments, loan losses, stressed loans, backup savings for bad loans versus loan growth, office and credit card stress, and paper losses if long-term rates rise further. High inflation also keeps pay, tech and legal costs high.

In my view, differences between JPMorgan, Goldman Sachs, Citigroup and Wells Fargo matter more than the average. A broad 20% rise says less than the split between trading returns and basic lending returns, and less than how each bank prices deposits. If records rest on costly borrowing or wide loan markups while loans sour, future profit quality is weaker. If lasting fees and careful savings do the work, payouts have more room even if lending stays slow.
