The Commodity Futures Trading Commission (CFTC) has revised its staff letter 25-40 as of February 6, 2026, to officially recognize national trust banks as issuers of stablecoins. According to NS3.AI, the initial framework released in December 2025 had inadvertently excluded OCC-chartered trust banks from eligibility to use margin collateral associated with stablecoins. This amendment eliminates the previous two-tier system, ensuring consistent regulatory treatment for stablecoin issuers across trust banks.
