Apollo economist warns AI agents could trigger an 'agentic bank run' on cheap bank deposits

Apollo chief economist Torsten Slok's thesis: US checking accounts average just 0.1% APY while banks earn 4-5% net interest margins on that cheap deposit base. Personal AI agents (like Meta's Muse) with account access could shift idle cash to high-yield options in milliseconds at scale, draining bank deposits and forcing either higher rates or a liquidity crunch. Coinbase's x402 protocol even enables agents to make instant stablecoin micropayments without card networks.

The poster adds a practical angle: at small scale this is easy to grasp — thousands of agents querying balances, transferring, and changing auto-payments all in the same second. For individuals, setting spending limits isn't enough; you also need defaults for over-limit/anomalous/batched actions (block or allow?) and a way to be woken up when things stop.
