Why This Week's Bank Results and Inflation Report Matter for Your Money

JPMorgan, Goldman Sachs, Citigroup and Wells Fargo were set to report third-quarter 2026 results in the week starting October 9, with bank earnings and inflation data leading the market calendar while the S&P 500 hovered near records. The S&P 500 is a list of about 500 large U.S. companies that many savings and retirement accounts follow.

The big, everyday banks and the Wall Street trading firms were first to report. JPMorgan and Goldman Sachs were among the banks due that week, when earnings and inflation data were expected to drive prices. A separate preview listed JPMorgan, Goldman Sachs, Citigroup and Wells Fargo as the reporters in focus for the quarter. Reuters

Expectations were high. Analysts polled by FactSet expected the five biggest Wall Street banks to grow earnings per share by an average of 20% from a year ago. Earnings per share means profit divided by each share of stock. Analysts on average expected S&P 500 earnings to jump over 30% ahead of the third-quarter earnings season starting with reports from large U.S. banks. Reuters

Trading income was the swing item. The Wall Street Journal published an article titled "Wall Street's Trading Desks Come Down From a Record High" on September 30, framing the quarter around a return to normal after a very strong run. Investment-banking revenue reached $61.4 billion in the first half of 2026, up 24% from a year earlier, according to Dealogic data. The Wall Street Journal

This pattern was familiar. In its July 13, 2026 stock-market live coverage, the Journal noted investors were gearing up for a busy week of bank earnings and key inflation data, the same earnings-plus-CPI test as the October week. CPI is the Consumer Price Index, a monthly check on what households pay. The Journal published an article titled "October: A Time for Investors to Reap…and Sow" on September 29.

The broader context here is that trading was cooling while fees held up. Like a shop after a holiday rush, the quarter comes down to two lines: trading results and fee income from underwriting plus advice on deals. The 20% bank target sits below the 30%-plus target for the wider market. With stocks near records and an inflation report in the same week, a simple beat may not be enough if the mix is weak.

In my view, savers should watch differences between banks, not the average. The 20% figure covers five banks with different mixes of trading, advice, deal fees and lending. A beat from one-time items like reserves and taxes is different from a beat from client business. Early bank reports set the mood but do not decide the whole season.
