Regulation – and sovereignty – loom large
Technical interoperability will help determine the success of tokenised finance. But regulation and sovereignty may ultimately determine who shapes it.
In this context, the most important recent development in digital assets is the 2025 Genius Act, which has created a regulatory framework for payment stablecoins. The Clarity Act, which has advanced through the Senate Banking Committee but still requires further action in Congress, is aimed at providing greater clarity for cryptocurrencies and other digital assets. Together, they reduce uncertainty by outlining clearer rules for issuers, exchanges and brokers.
The US previously lagged other jurisdictions on regulation related to digital assets but new rules strike a different tone – far more market-led and encouraging experimentation. At the same time, questions remain around how these frameworks will interact internationally, with a risk that differing approaches could increase fragmentation and limit interoperability.
The stakes are high because the Genius Act, in particular, could accelerate a broader recalibration of default currencies. If US dollar-denominated stablecoins – backed by US Treasuries – become the dominant global format, the implications go far beyond payments. The US could reinforce dollar dominance and fund itself more cheaply, while other economies might face higher borrowing costs and potential constraints on fiscal sovereignty.
The opportunities, however, are also significant. Stablecoins create new flexibility in how legitimate actors transmit value across borders. In a fragmented geopolitical environment, some countries will not want every transaction to depend on rails shaped primarily by US priorities. There may be growing demand for robust alternatives – including digital euro or sterling-denominated rails – but those alternatives will only become contenders if they can work across systems, jurisdictions and use cases.
For guidance, regulators should look to past successes – such as the UK’s approach to fintech over a decade ago – to get the balance between safety and innovation right. The UK, the EU and other financial centres around the world need to play an important role in the digital asset era. But they need to collaborate on common standards and innovation-friendly regulation that allows tokenised finance to develop without becoming fragmented.
The digital asset debate has moved on. Tokenisation is not a sideshow to crypto. It is part of the long-term evolution of money – and an infrastructure question that could help define the next era of finance.
