Agentic commerce creates a new payments problem: the customer may authorize an AI agent without explicitly choosing the final transaction. When something goes wrong, proving intent may matter as much as proving identity.

Sponsor banks are not just payment plumbing. They are risk partners, and they do not like discovering late that your merchants, volume, fraud, chargebacks, ACH returns, vendors, or product roadmap have drifted outside the story they approved. If you depend on a sponsor bank, clear communication, real controls, clean reporting, and early escalation are not optional.
