Big banks block outside AI agents from customer accounts. Payments firms are defining who authorizes agent-led purchases.
Financial firms are moving from AI experiments to access control. The near-term winners will be banks, card networks, and insurers that can prove consent, limit automated actions, and keep people accountable for consequential decisions.
Inside
- Banks restrict outside agents from direct account access.
- Payments firms build rules for agent-authorized purchases.
- Regulators focus on AI control, recovery, and consumer harm.
- Insurance keeps human judgment around pricing and claims.
- AI shows narrow workflow gains, not yet clear bankwide returns.
