JPMorgan Chase has blocked AI agent access to customer accounts, according to crypto analyst @biancoresearch. The restriction took effect this past week and prevents users from connecting AI tools to their Chase banking data. The move suggests banks are concerned that customers using AI agents to optimize yields could threaten traditional revenue models built on passive deposit balances and fee structures. By cutting off programmatic access, financial institutions may be attempting to limit automated strategies that could shift capital toward higher-yield alternatives more efficiently than manual banking allows.
