Stablecoin oversight is becoming a dollar funding problem

Stablecoin oversight has become a dollar funding problem. The Treasury has proposed the first formal GENIUS Act definitions for determining who must license a stablecoin issuer. A BIS-IMF working paper finds that stablecoin purchases in non-dollar economies spill into traditional currency markets and raise dollar funding costs for banks and corporates that never touched crypto. Put the two documents side by side and the stablecoin debate becomes a question of which institutions absorb dollar liquidity pressure.

The Treasury definitions carry the institutional stakes. Tether's treatment is unresolved, and a congressional rewrite hangs over a January 18 deadline. The definitional choices will determine whether a stablecoin issuer like Tether sits inside the US regulatory perimeter or outside it. A definition that reaches issuers by economic substance pulls it in; one that stops at legal domicile leaves it out.

The BIS-IMF paper explains why the perimeter matters. A buyer in a non-dollar economy who wants a dollar stablecoin sells local currency to get dollars. That trade lands in the foreign exchange market, and the paper finds the resulting dollar demand spills into traditional currency markets, tightening funding conditions for banks and corporates with no crypto exposure. The transmission runs through dollar funding costs, not through crypto balance sheets.

Stablecoin issuance is therefore a dollar funding business even before it is a payments business. The issuer collects dollar claims; its users in non-dollar economies generate the FX bid. Regulatory treatment decides whether that funding activity carries capital, liquidity and custody requirements or none at all.

The first GENIUS Act rule has Tether as its test case. The treatment of the stablecoin issuer is unresolved, and Congress is rewriting the definitions before the deadline. If the final language captures issuance by economic substance, Tether would be inside the perimeter, facing licensing, reserve custody and redemption requirements. If the language turns on legal domicile, Tether remains outside, but the dollar demand its users create still flows through currency markets and still lands on the funding costs of banks and corporates.

The same deadline means the definitions are not final. A congressional rewrite can sharpen them or dilute them. The Treasury's proposal is the starting point; markup decides the end. For an RIA or family office deciding where to park short-term dollars, that end point determines whether a stablecoin amounts to a supervised money market instrument or an unregulated claim on the dollar system.

The rest of the digital-asset agenda is moving slower. The SEC postponed Regulation Crypto without setting a new date. The tokenized-stock exemption Chair Paul Atkins has talked up is not on the agency's agenda. The stablecoin lane is moving while the broader SEC agenda is parked, and the mix looks deliberate: an execution problem with tokenized stocks stays contained to trading venues, while a stablecoin dollar-funding problem can reach banks and corporates through the FX market.

That ordering lines up with the BIS-IMF channel. Postponing Regulation Crypto holds the broad market-structure fight in place. Moving the stablecoin definitions forward puts the dollar funding question first. Regulators schedule what they think can break something; the BIS-IMF paper says stablecoin demand qualifies.

Franklin Templeton's tokenized money fund shows what the inside looks like. SEC staff no-action relief puts FOBXX under Rule 17f-2's cash and collateral framework, giving the onchain fund a custody home and making it a practical institutional cash tool. That is the closest regulated analog to a licensed stablecoin: a dollar token backed by assets that fit Rule 17f-2's cash and collateral rules, held under SEC custody, with redemption obligations.

For RIAs, the distinction is not regulatory theory. The choice between a stablecoin and a tokenized money fund is a choice about what stands behind the token and who supervises it. The Treasury's definitions decide which dollar tokens carry a money-fund-style backstop. The BIS-IMF paper says the demand itself moves dollar funding markets; the definitions decide whether that demand is supervised.

January 18 carries the yes or no. If the Treasury's definitions reach offshore issuance, stablecoin dollar funding moves inside the perimeter and Tether becomes a supervised dollar book. If they do not, the funding demand stays offshore and the spillover keeps showing up in dollar borrowing costs for banks and corporates that never touched crypto. The definitions in the rule will say more than any SEC agenda item.
