Stablecoins Just Got Their First Real Federal Rulebook

The GENIUS Act, the first comprehensive federal law regulating stablecoins, passed in 2025. But a law that sets up a licensing framework isn't the same as a functioning regulatory regime — that requires actual rules from the agencies responsible for enforcing it. Throughout 2026, Treasury, the Office of the Comptroller of the Currency, and the FDIC have been publishing those rules, piece by piece, and the emerging picture is less about reserve requirements than most crypto coverage assumed.

What the law actually created

The GENIUS Act establishes a category called "permitted payment stablecoin issuers" (PPSIs) and sets baseline requirements — reserve backing, redemption rights, disclosure — for any company that wants to legally issue a dollar-pegged stablecoin in the U.S. Multiple regulators share jurisdiction depending on an issuer's structure: the OCC for federally chartered issuers, the FDIC for insured-depository-affiliated issuers, and state regulators for others, with Treasury coordinating the anti-money-laundering side across all of them.

The part getting less attention: AML, not reserves

The specific rule Treasury proposed in 2026 doesn't primarily address how much cash or Treasury bills a stablecoin issuer has to hold — the Act itself already sets that baseline. It instead subjects permitted payment stablecoin issuers to Bank Secrecy Act obligations, treating them as financial institutions for anti-money-laundering purposes and requiring an "effective sanctions compliance program." Treasury's stated intent is rules that are "fit for purpose" and that "minimize unnecessary burden" while still giving law enforcement the tools it needs — a middle path between full bank-style regulation and the largely unregulated status stablecoins operated under previously.

The emerging picture is less about reserve requirements than most crypto coverage assumed — it's about treating stablecoin issuers as financial institutions for anti-money-laundering purposes.

Why this matters for tokenized assets generally

Stablecoins are the settlement layer underneath most of the broader tokenization trend, including the tokenized Treasury market we've covered before — a market that depends on stablecoins as the actual medium of exchange moving in and out of tokenized positions. A clear federal compliance framework, even a demanding one, is generally viewed by institutional players as preferable to regulatory ambiguity, because ambiguity is what kept banks and asset managers on the sidelines for years.

What issuers actually have to do next

Once these rules are finalized, PPSIs will need to register with the relevant supervisor, stand up a documented sanctions and anti-money-laundering compliance program modeled on existing bank requirements, and maintain records to the same standard banks already do. That's a meaningfully higher operational bar than most stablecoin issuers operated under previously, and it's likely to accelerate consolidation toward issuers large enough to absorb real compliance costs.

The honest caveat

As of September 2026, these are still proposed rules open for public comment, not final regulations — the rulemaking process typically takes months to finalize after a comment period closes, and the specifics can and do change in response to industry pushback. The GENIUS Act itself is settled law; the operational rules that determine exactly what compliance costs an issuer will actually bear are still being written.
