Jim Bianco: Banks Block AI Agents to Protect Deposit Profits

Bianco frames the restriction as a business-model question, not a security one: idle deposits are a revenue source, and AI agents capable of moving that cash threaten the spread banks earn on it. That puts agent access to banking rails in the same category as other channel conflicts, where incumbents control the interface to defend economics. The open question is whether blocking external agents becomes an industry norm or stays a single-bank posture, and whether customers treat the restriction as protection or as a cost.
