Apollo Economist Warns AI Agents Could Trigger Bank Deposit Flight

An artificial intelligence agent that automatically shifts a saver’s cash toward the highest-yielding account may sound like a convenience. Torsten Sløk, chief economist at Apollo, says it could also become a structural threat to the way American banks fund themselves. In a note issued Sunday, September 27, 2026, Sløk warned that AI agents such as Meta’s newly launched Muse could siphon deposits out of low-yield checking and savings accounts and into higher-paying alternatives, en masse and without friction.

The concern is not hypothetical laziness on the part of consumers, which has long kept trillions of dollars parked in accounts paying next to nothing. It is the removal of that laziness by automation. If software can do in seconds what a human saver never bothered to do — compare rates across thousands of institutions and move money accordingly — the inertia that banks have quietly relied on for decades could evaporate.

Why cheap deposits matter to banks

According to FDIC data cited in Sløk’s note, the national average rate on a checking account sits at just 0.1%, while savings accounts average 0.4%. By contrast, a range of fintech and online accounts he tracked pay between 3.3% and 5%, with Adelfi topping the list at 5% and SoFi offering 4.5%. The arithmetic is stark: $10,000 sitting in an average checking account earns roughly $10 a year in interest, while the same sum in a top-yielding alternative could generate $500.

That gap has existed for years, but most depositors have not acted on it, whether from inertia, loyalty, or simple lack of time to shop around. Banks use this cheap, stable deposit base to fund loans — mortgages, auto loans, credit lines — at a profitable spread. If AI agents make rate-shopping instantaneous and effortless, that spread narrows or disappears, and the cheap-money engine that underpins lending starts to sputter.

Meta’s Muse and the plumbing behind it

The trigger for Sløk’s warning is Muse, an AI agent Meta launched on September 8, 2026. Muse is integrated with Plaid, the financial data network that connects more than 12,000 US institutions and apps, giving the agent visibility into balances and account data across a huge swath of the banking system. Notably, Plaid’s own announcement does not confirm that Muse can actually initiate transfers of funds between accounts — only that it can access financial data. That distinction matters: an agent that can see everything but move nothing is a rate-comparison tool, not a deposit-draining mechanism. Whether Muse or its successors cross that line is the open question at the center of the debate.

Wall Street, for its part, is not waiting to find out. JPMorgan recently raised its price target on Meta, citing Muse’s growth potential — a signal that at least some analysts see the agent’s financial integration as a business opportunity rather than a systemic wrinkle, or perhaps both at once. Commentators including Mike Zaccardi and Nate Geraci have amplified Sløk’s warning, framing it as a preview of how AI could reshape retail finance faster than regulators can respond.

A parallel fight over yield in Washington

The episode lands amid a separate but related fight in Washington over who gets to offer yield on digital dollars. The Clarity Act, a crypto market structure bill that would have set rules for stablecoins and digital assets, failed a Senate procedural vote on September 15, 2026. Part of the dispute centers on whether stablecoin issuers should be allowed to pay yield directly to holders, competing even more directly with bank deposits. Coverage of that collapse, including the Senate crypto bill’s collapse amid a Trump ethics fight and the broader Senate deadlock pushing crypto rules into regulators’ hands, underscores that the yield question is not confined to AI agents and fintech apps — it is a live regulatory battle with stablecoins on one side and bank deposits on the other.

What to watch next

For now, Sløk’s warning is a forecast of a mechanism, not a documented run on deposits. Several concrete developments will determine whether it becomes more than that:

• Whether Meta or other AI developers confirm that agents like Muse can execute transfers, not merely display balances and rates.
• Whether banks respond by raising rates on checking and savings products to retain deposits, narrowing the yield gap that makes automated switching worthwhile.
• How regulators, including the Federal Reserve, address deposit stability as fintech and AI tools proliferate — a question that echoes the compliance pressure already visible in the Fed’s new 392-page stablecoin rule with its 48-hour reserve-gap countdown.
• Whether Congress revisits stablecoin yield rules in a future version of market-structure legislation, given the Clarity Act’s failure.

None of this guarantees a crisis. But it does suggest that the boundary between banking, fintech, and AI is thinner than regulators assumed, and that the next stress test for deposit stability may not come from a market shock at all — it may come from a piece of software doing exactly what it was designed to do.
