The AI ‘scare trade’ is finally hitting banks. Bargain hunters should take note.

Banks have benefited in recent years from a simple dynamic: when rates rise, lenders can earn more on loans while continuing to pay depositors very little on checking accounts. Customers often leave those balances in place because of convenience and easy access to cash, even when better yields are available elsewhere. That reluctance has supported bank profits.

Now the so-called AI "scare trade" is reaching the sector, suggesting investors are rethinking how durable those deposit advantages may be. The concern is not a single event but a shift in sentiment: if technology makes it easier for customers to compare and move money, or changes how banks compete, the value of sticky, low-cost deposits could come under pressure.

What to watch is whether deposit costs rise, how quickly customers respond to better alternatives, and whether banks can offset margin pressure through other revenue. For observers, the key question is whether this is a lasting repricing of bank earnings power or a temporary swing in market mood.
