Q3 Bank Earnings Preview: Profit Path Uncertain

Big banks kick off third-quarter earnings season on Tuesday with a solid 2025 track record. The steeper yield curve and a heavy dose of summer investment banking activity suggest global U.S. banks remain on solid footing but face possible challenges. One of which is how to follow up a second quarter where sweeping market volatility sent Wall Street trading demand soaring, much to the big banks' benefit.

"After a strong post tariff-tantrum rally that lasted through the summer, performance has stalled over the last month with the S&P financials sector being one of the worst performing over that time period," said Alex Coffey, senior trading and derivatives strategist at Schwab. "While this could be tied to uncertainty around macroeconomic trajectory and monetary policy, it is more likely due to many of the big banks seeing a short-term peak in earnings growth last quarter and a notable deceleration expected in the coming quarters."

One factor behind the possible earnings deceleration could be Federal Reserve policy because expected rate cuts can dent banks' profitability. Banks also face tough comparisons to past earnings results, which could slow profit growth year over year in the coming quarters. But during the third quarter, the sector seemed to be in a sweet spot of relatively high rates and an improved climate for investment banking that could likely support earnings for companies most exposed to initial public offerings (IPOs) and mergers and acquisitions (M&As).

Banks often profit most when they can borrow at low rates and lend at higher ones, and that's exactly what the current Treasury yield curve allows. Long-term rates now hold a solid premium to short-term ones, a scenario that provided strong momentum for bank shares since the April "Liberation Day" market dive. Momentum slowed slightly in the third quarter, but the Nasdaq Bank Index (BANK) still rose 3%.

Last month's rate cut kept pressure on short-term Treasury note yields, while long-term yields—less influenced by Fed policy—are below summer peaks. Still, the 10-year Treasury note yield remains above 4%, which is relatively high. Falling yields can stimulate more investment banking activity, and the slight drop in yields approaching the Fed meeting possibly accounted for some of the resurgence in IPOs and M&As.

The futures market dials up more rate cuts ahead, but what the market wants and what it ultimately gets aren't always the same. The 10-year Treasury note yield rose 100 basis points from its lows a year ago as the Fed cut rates—not necessarily what investors had expected. Yields initially rose again in September after the first rate cut of 2025. The flip side of a steeper yield curve for banks is the negative impact it can have on consumer borrowing for mortgages and furniture and on business borrowing for heavy equipment and new manufacturing facilities.

The summer featured record highs for major U.S. indexes and saw M&As and IPOs surge to levels last seen in the post-pandemic go-go year of 2021, when some crypto and tech IPOs soared.
