Every month you don’t refinance, don’t catch the late fee, and don’t move the cash idling in checking, you pay a tax no government collects. The Journal calls it a laziness tax, and the bill is bigger than it sounds: about $7.12 trillion sits in consumer and business checking accounts, per the St. Louis Fed, much of it earning little or nothing. For banks, that inertia isn’t a flaw in the system. It is the system — cheap deposits in, loans out, the spread kept.
Now the bots have noticed. Torsten Slok, chief economist at Apollo Global Management (APO), raised the prospect of an “AI-induced bank run” — assistants that quietly sweep a household’s cash into whatever pays more, no branch visit required. The line got around on X, Jasmine Li reports, and it opened a bigger ledger: AI that disputes fees, renegotiates bills, and watches mortgage rates. Morgan Stanley (MS) Research estimates AI could double the share of borrowers who refinance or prepay. United Wholesale Mortgage already runs software that spots a client who’d save money on a refi — and calls them. Harvard economist John Campbell told the paper that consumer inertia has been one of the most powerful forces shaping the industry. Translation: the business model is you, not noticing.
Markets did notice. Financial stocks, consumer banks included, slid last week after Meta Platforms (META) released Muse, an assistant pitched as an instant money saver. It can act on your behalf — flag the subscriptions you forgot, haggle the utility bill — though it can’t yet move account balances on its own.
Why the run probably walks
The Journal’s skeptics make a fair case. Corporate treasurers already sweep cash daily — they never needed a chatbot. Many household accounts hold a few thousand dollars, so the prize per family is modest. Trust is sticky: Crane Data’s Peter Crane notes people won’t hand savings to a bank they’ve never heard of. And a bot’s recommendation is only as clean as whoever built it — blind spots included.
Our read
Cash Flow (M5) and Time Value of Money (M3): the laziness tax is already optional, which is the point everyone skips. A three-month Treasury bill paid about 4.20% at Wednesday’s close; the checking account holding your float likely pays nothing. That gap is the whole tax. Our desk parks cash in Treasury bills and floating-rate paper (SGOV, USFR) for exactly this reason. You don’t need a bot — you need one afternoon: list every account, write its yield next to it, and move whatever you won’t touch for sixty days into something that pays. Set the refi alert too.
An assistant that sweeps your cash in 2027 is a fine idea. A household that swept it this weekend is a better one — and if you’d like a second set of eyes on where your cash actually sits, that review is quicker before the rain starts than after.
