Does a spending limit belong to the agent or to the principal
Card networks are building ways for a merchant to recognise an agent, and bankers are calling for transaction limits on agents. Nobody has settled whether a limit attaches to the agent, so it holds across every account it touches, or to the principal's account, so a second agent can spend the same money again.
The verdict
Open question
No settled answer exists. The ledger poses the question, links the live debate, and does not answer it.

- The Visa Trusted Agent Protocol addresses recognising an approved agent and its intent, and does not itself carry a spending ceiling.
- Press reports attribute to the State Bank of India's chairman a call for transaction limits as part of a know your agent discipline.
- The Agent Passport System Internet-Draft treats spend as one of the constraint dimensions a delegation chain may not widen, and it is not an adopted standard.
- No published rule states whether two agents acting for the same person share one limit or hold one each.

Limits. Stated means the document you can open below says it; silent means the ledger read the document and it does not.

- Whether a spending ceiling is a property of the agent or of the account it draws on is unsettled, and the two answers give very different exposures.IETF Datatracker, draft-pidlisnyi-aps-03, primary source, 18 July 2026.
What it changes
For a team deploying an agent
Until this settles, set the limit in both places. Cap the agent in its own configuration and cap the account or card it draws on, because a control that exists only inside the agent is a control the agent can be talked out of by text it reads on a web page.
