Treasury's proposed GENIUS Act implementing rules would, by July 18, 2028, bar US-regulated 'digital asset service providers' from offering or selling payment stablecoins issued by any non-qualifying foreign issuer to American customers. The broader regime takes effect Jan. 18, 2027, requiring issuers to be inside the GENIUS framework to issue into the US, with the distribution ban closing the back door eighteen months later. The public has until Oct. 19 to comment before Treasury finalizes definitions and diligence standards.
Why it matters
The proposal draws the regulatory border not at the blockchain but at the regulated business. Self-custody, peer-to-peer transfers, and software that simply holds assets stay outside the framework, so an American can still hold or receive an offshore token after the cutoff. What they cannot do is buy, swap, or deposit that token through a covered exchange, custodian, or hosted wallet without the issuer clearing Treasury's foreign-issuer route under Section 18. That route requires a comparable home regime, OCC registration, and proof the issuer can comply with lawful US orders, including freezing or burning tokens at specific addresses. Treasury rejected a temporary safe harbor for smaller foreign stablecoins, accepting market concentration as an explicit cost.
Market impact
The asymmetry between the three largest dollar tokens is large. USDT, at roughly $183 billion in market cap, dominates offshore dollar liquidity and currently trades on major US venues including Coinbase and Kraken. USDC ($73.3B) and PYUSD ($2.9B) approach the 2028 deadline from inside the US: Circle has final OCC approval for a national trust bank, and PYUSD is issued by Paxos Trust. Tether holds El Salvador licenses, has demonstrated it can freeze addresses for US authorities, and has launched USA₮ as a federally regulated dollar token. Liquidity providers may need separate US and offshore inventories, users may have to convert one token to another before depositing to a US exchange, and trading pairs may split by region. A $183 billion market cap will not, by itself, keep USDT on an American menu in 2028.
Frequently asked questions
-
What does Treasury's proposed GENIUS Act rule ban?
By July 18, 2028, US-regulated exchanges, custodians, and hosted wallets could not offer or sell payment stablecoins from non-qualifying foreign issuers to American customers. Self-custody and peer-to-peer transfers stay outside the framework.
-
Why does the rule target exchanges rather than the blockchain?
A regulated exchange or custodian is easier to supervise than millions of direct blockchain transfers. Treasury's proposal makes those businesses verify each stablecoin issuer's legal status, leaving the protocol free to process transfers that happen without them.
-
What does Tether need to do to keep USDT on US exchanges in 2028?
Tether must clear Section 18's foreign-issuer route: a home regulator comparable to US rules, OCC registration, and proof it can comply with lawful US orders including freezing or burning tokens at specific addresses. It can also redirect demand to USA₮.
-
Can US customers still hold or receive USDT after the 2028 cutoff?
Yes. Self-custody, peer-to-peer transfers, and asset-holding software sit outside the framework, so an American can still hold or receive an offshore token. The friction begins when they try to buy, swap, or deposit it through a covered exchange or custodian.
-
How do USDC and PYUSD differ from USDT under the proposed rule?
USDC ($73.3B) and PYUSD ($2.9B) approach the 2028 deadline from inside the US: Circle has final OCC approval for a national trust bank, and PYUSD is issued by Paxos Trust. USDT ($183B) is issued from El Salvador and must clear the Section 18 foreign-issuer route to keep a US menu spot.
