Major US Banks Restrict AI Agent Access Using Customer Credentials

Several major US banks, including Morgan Stanley, JPMorgan, Bank of America, and Wells Fargo, are restricting external AI agent access that uses customer-provided credentials, violating bank policies requiring personal account holder logins. Morgan Stanley already blocks AI agents entirely, and JPMorgan, Bank of America, and Citi are implementing similar restrictions, with most banks preferring read-only access due to high security risks and uncertainty over whether agents act on user instruction or autonomously.
