Fifth Third CEO says online-only banks face most AI cash-sorting risk

For the head of consumer deposits at a regional bank

Fifth Third CEO Tim Spence said on Oct. 19, during the Cincinnati-based bank's third-quarter earnings call, that online-only banks that compete on pricing alone face the most risk from AI-driven cash optimization tools such as Meta's Muse.14

The launch of Meta's AI assistant Muse has renewed concern among lenders that agentic AI could sort cash toward higher yields and threaten deposit businesses, according to Banking Dive.1 Spence said history shows firms hit hardest by platforms that reduce friction or increase transparency are those whose only value proposition is price, and that Fifth Third will build Muse-style services such as subscription review and budgeting into its own apps.41

CFO Bryan Preston said on Monday that concerns about AI-driven cash optimization are "likely overblown" and that adoption timelines probably accelerated, but that the $301 billion-asset bank is not dismissing the issue, according to Banking Dive; he also said Fifth Third's median household checking account balance is $3,000, so there is little excess that might be moved in search of higher yield.1

Preston said Fifth Third does not currently allow AI agents to initiate transactions in customer accounts and that accountability questions need to be settled first; he also said commercial deposits are largely operational.1

According to Banking Dive, citing the Financial Times, Citi and Bank of America have joined JPMorgan Chase in blocking customers' external AI agents from accessing bank accounts; Schwab CEO Rick Wurster told Bloomberg his firm is also blocking them, per The Verge.13

Third-quarter deposit costs rose 10 basis points to 1.64%, and Preston said deposit competition has been more intense this year than in the last few years, according to Banking Dive; average core deposits grew 3% sequentially to $236 billion, per the bank's earnings release as cited there.1

Why it matters

Large banks are blocking external agents, while Fifth Third is betting on copying agent features inside its own apps and on sticky checking balances. Deposit pricing pressure is already showing in costs, so executives should test whether their own balance profile and product bundles hold up if agents become common.

From the brief

Our take. Fifth Third calls agent cash sorting overblown because its median checking balance is $3,000. Yet its deposit costs rose 10 basis points last quarter with agents barred from initiating transactions. The rate pressure your board should price is already human.

Action. Digital banking: Confirm whether third-party agents or aggregators can initiate transfers from consumer accounts, and document the policy for the board.

What our records say

Fifth Third's AI strategy is built around what its CIO calls "enterprise-viable AI": tools that survive a regulated bank's controls and show returns, deployed while the bank absorbs its $10.9 billion Comerica acquisition.
