Wu said that the CFTC reissued Staff Letter 25-40 on February 6, with limited revisions to the definition of "payment stablecoins," clarifying that national trust banks can serve as compliant issuers; the letter was originally issued on December 8, 2025, taking a no-action stance on futures commission merchants accepting non-security digital assets, including payment stablecoins, as customer collateral, and holding some of their own payment stablecoins in customer segregated accounts. This update aims to prevent the previous definition from unintentionally excluding national trust banks and to expand the scope of qualified issuers.
