Wells Fargo's CFO Flags Sharp Slowdown in Late-September Trading

Wells Fargo's chief financial officer told investors that trading activity at the bank slowed "sharply" in the final weeks of September, according to remarks circulated by TradingView. The disclosure lands ahead of Wells Fargo's third-quarter earnings release and offers an early read on Wall Street's late-summer pulse.

For practitioners running bank earnings models, the comment reframes a quarter that had been tracking ahead of consensus through August. A late-quarter deceleration is exactly the soft signal that doesn't always show up in the sell-side previews, because trading desks build their forecasts off mid-quarter client surveys rather than the closing weeks.

Why does the late-September weakness matter?

The CFO's "sharply" framing is the operative word. Trading revenue books in real time, and the final ten sessions of September typically set the tone for the print that lands in mid-October. A pullback noticeable enough for the bank's finance chief to flag suggests client orders slowed enough to show up on the desk-level P&L.

Capital markets revenue is also the swing variable in Wells Fargo's non-interest income mix — the line corporate clients watch when they underwrite debt or handle stock buybacks. Lighter trading flow now would dent the recovery narrative at the moment Wells Fargo's asset cap is being relaxed and the bank resumes capital returns to shareholders.

What's the broader backdrop?

U.S. equity volumes spent most of August running ahead of their five-year averages, while the Cboe Volatility Index drifted to multi-month lows. Low realized volatility typically pulls institutional order flow off the wires and onto passive vehicles, which don't generate trade tickets for bank desks.

September is historically the S&P 500's weakest calendar month, posting an average loss in most years since 2000. A crowded macro calendar landed inside the same window this quarter, and "thin and cautious" became the operational default at most trading desks.

That makes the CFO's tone consistent with what brokers already suspected about the month. The incremental information is the timing: the slowdown came late enough to dent full-quarter revenue, not just early-September softness.

What does this change for traders and analysts?

The practical question, for anyone with a bank book heading into earnings season: how much should Q3 trading-revenue estimates come down? Probably a few percentage points at Wells Fargo, and possibly more if peers confirm the pattern over the next two weeks.

Three things to watch:

• Mid-quarter commentary from JPMorgan and Citigroup, both of which run larger trading desks.
• The September ISM Manufacturing and Nonfarm Payrolls prints as read-throughs for client risk appetite.
• The corporate-deal calendar — a fresh wave of M&A or bond issuance would signal corporate clients are still willing to lean in.

Until the Q3 prints land, the CFO's word is one data point. But for traders recalibrating fourth-quarter assumptions right now, it's a useful early signal that the street's hot summer didn't carry into autumn.
