U.S. and UK Seek to Open Cross-Border Stablecoin Payments and Securities Settlement
On July 14, the U.S. Treasury and the UK Treasury issued a joint statement saying they will promote the use of compliant stablecoins for cross-border payments and settlement in securities and commodities markets, and explore a regulatory path for stablecoins issued in each country to enter the other’s market.
On July 14, the U.S. Treasury and the UK Treasury jointly placed stablecoins at the center of discussions on cross-border financial infrastructure. The two countries issued a joint statement proposing support for the use of compliant stablecoins in cross-border payments, securities settlement, and capital markets transactions, and exploring a clear path for stablecoins issued in the two countries to gain access to each other’s markets.
This is not yet an effective market-access rule, but it is a signal of policy coordination. Its significance lies in the fact that stablecoins are no longer described only as a settlement tool for crypto trading, but are being placed within the payment, custody, and securities settlement chains between the U.S. dollar and sterling financial systems.
What happened
The U.S. Treasury and the UK Treasury released two documents under the framework of the “Transatlantic Taskforce for Markets of the Future”: one was ten recommendations on digital assets and capital markets cooperation, and the other was the joint stablecoin statement.
The joint statement proposed that stablecoins can be used for cross-border payments and capital markets settlement; private digital currency forms such as stablecoins and tokenized deposits can coexist in a multi-currency ecosystem. The two countries also said that for stablecoins “used as money,” reserve assets should at least be backed one to one by high-quality, highly liquid assets, and emphasized reserve segregation, custody, redemption rights, and the legal claim rights of holders in the event of an issuer’s bankruptcy.
More notably, the two sides support the use of compliant stablecoins in securities and commodities markets as a settlement tool, while planning to explore a formal mechanism for stablecoins from the two countries to cross-border enter each other’s markets. The accompanying recommendations also include establishing a one-year working group led by the private sector to test cross-border applications of tokenized assets, and studying the finality of tokenized securities settlement and whether stablecoins or tokenized money market funds can serve as collateral for central counterparty margin.
Why it matters
The real competitive arena for stablecoins may not be coin-to-coin trading on exchanges, but rather how money moves in financial markets. If stablecoins can be used compliantly for securities delivery, margin, and cross-border payments, the waiting time for funds in transaction chains, the number of bank intermediaries, and friction in cross-border flows all have a chance to decline.
For issuers, the policy focus is also shifting from “whether they can issue” to “whether they can enter financial institutions and market infrastructure.” The statement explicitly supports compliant stablecoin issuers and users in accessing banking and other financial services on a risk-based basis, sending a clearer commercial signal to custody, market-making, clearing, and payment service providers.
For market structure, the U.S. and UK are trying to place different forms of digital money under the same regulatory logic: similar risks should face similarly outcome-oriented requirements, while avoiding overly localized reserve and liquidity conditions on each side. If implemented, stablecoins could become an intermediate layer connecting tokenized securities, bank deposits, and traditional clearing networks, rather than just an independent crypto asset class.
But this is still a coordination agenda, not an indication that the two countries have already completed legal mutual recognition, nor does it mean all stablecoins will be able to enter securities markets. The statement repeatedly uses terms such as “propose,” “explore,” and “support,” and the final outcome will depend on legislation in the U.S. and the UK, regulatory details, and whether financial institutions are willing to connect.
What to watch next
First, how the two countries will define compliant stablecoins eligible for settlement, and whether requirements for reserve assets, redemption, and bankruptcy segregation can truly be made compatible. Second, whether the SEC, the CFTC, the UK Financial Conduct Authority, and the Bank of England will turn the policy language into pilots, exemptions, or formal rules. Third, whether stablecoins can enter central counterparty margin systems, which will directly determine whether they upgrade from a payment tool to a market liquidity tool.
It will also be important to watch the actual response from banks and payment institutions. Regulatory documents can reduce legal uncertainty, but they cannot automatically solve fragmented liquidity, foreign exchange conversion, on-chain compliance, and operational risk. The next stage of the U.S.-UK statement is not another principles paper, but whether verifiable cross-border trading, settlement, or tokenized asset pilots can emerge.
