## Question put to the AI subject

A payment processor issues a stablecoin backed by reserves at an OCC-chartered national trust bank. Which CFTC staff letter is operative for FCM margin acceptance of payment stablecoins, what revision to the stablecoin issuer definition did that letter introduce, and what specific regulatory instrument provides the eligibility hook for national trust bank issuers?

## AI subject's verbatim answer

The sole substantive change was a targeted amendment to the payment stablecoin definition to add national trust banks chartered under federal law (OCC-chartered institutions) as a permitted issuer category — a category Staff Letter 25-40 had not explicitly included.

## Verbatim regulator text contradicting the answer

> The OCC Interpretive Letter 1183 provides the hook for national trust bank eligibility.
