OCC’s Stablecoin Trust Bank Charters Violate “Major Questions Doctrine,” ICBA Suit Argues - Fintech Business Weekly | Jason Mikula

The Independent Community Bankers of America has filed suit challenging the Office of the Comptroller of the Currency's authority to grant national trust bank charters to stablecoin issuers, arguing the approach runs afoul of the "major questions doctrine." That legal principle holds that agencies need clear congressional authorization before taking actions of major economic or political significance.

At issue is whether the OCC can extend its chartering power to firms whose business centers on stablecoin issuance, or whether that step requires explicit legislation from Congress. The outcome could shape which firms may operate under a federal banking framework and how they are supervised.

For markets, the case adds a layer of regulatory uncertainty around stablecoin oversight at a time when stablecoins are increasingly woven into trading, payments, and collateral flows. What to watch: how courts interpret the scope of the OCC's chartering authority, whether Congress advances its own stablecoin legislation, and how any ruling affects the supervisory status of existing or pending charter applicants.
