For years, stablecoins have enjoyed the luxury of being everything to everyone. To crypto traders, they are chips at the casino. To emerging-market users, they are digital dollars in the pocket. To regulators, they are either a nuisance, a threat or a payments innovation, depending on the meeting. To bankers, they are a product they dismissed until it became clear that someone else might own the rails.
In the past weeks, the polite fiction began to wear thin. Stablecoins are no longer being treated as a clever bit of crypto plumbing. They are being dragged, slowly but unmistakably, into the argument about money itself.
The most important signal came from the UK. On 15 April, the FCA published its consultation on the perimeter guidance for the new cryptoasset regime, with applications expected to open from September 2026 and the regime taking effect from October 2027. The framework is not designed to flatter the industry. It is designed to domesticate it. Qualifying stablecoin issuers will have to be UK-established, fully backed, subject to statutory trust arrangements and capable of redemption on a tight timetable. That is not the language of crypto exceptionalism. It is the language of prudential regulation.
But the more interesting part sits one tier above. If a sterling stablecoin becomes systemic, it moves into the Bank of England’s orbit. The Bank’s proposal would require at least 40 per cent of backing assets to be held as unremunerated deposits at the Bank, with up to 60 per cent in short-term UK government debt. In other words, the UK is not merely asking stablecoin issuers to behave better. It is offering them a route, at scale, into the central bank balance sheet.
That is the quiet revolution. The UK is building the only G7 stablecoin regime that treats stablecoins not simply as payment instruments, but as a form of money that may one day need central bank support to be credible. Andrew Bailey has been sceptical of crypto for years, but his position on widely used stablecoins is more subtle: if they are to function as money, they must be regulated like money and have access to the institutional machinery that gives money its authority.
This is not the American approach. The US model, under the GENIUS Act, is more commercially attractive. Issuers can earn yield on Treasuries and other approved reserves. Nor is it quite the European approach. MiCA brings stablecoins inside a regulated perimeter, but it does not integrate them into the ECB’s balance sheet in the same way. The British model is sterner and less lucrative. A 40 per cent unremunerated reserve requirement is a brutal tax on issuer economics. But that is precisely the point. The Bank of England is not trying to create the cheapest stablecoin regime in the world. It is trying to create the most credible one.
For the more excitable corners of the industry, this will feel like a missed opportunity. Why would an issuer choose London when other jurisdictions offer faster approvals, wider margins and less central bank interference? The answer is that London is not competing for every issuer. It is competing for the issuer that wants to be treated as serious financial infrastructure. It is a regime designed to repel the lightly capitalised, the overpromotional and the merely opportunistic. That is not a bug. It is the filter.
The timing matters because the old stablecoin story is starting to fray. The headline numbers still look enormous. Stablecoin transaction volumes reportedly reached around $33 trillion in 2025. That sounds like an alternative financial system has already arrived. But a closer look is sobering. Retail velocity remains tiny, with one recent analysis putting stablecoin retail velocity at just 0.08 compared with 1.65 for traditional M1 money. Stablecoins move vast sums, but much of that movement still happens inside the crypto machine: exchanges, DeFi, arbitrage, treasury management and cross-border settlement. They are useful. They are growing. But they are not yet buying the weekly shop.
This is the great contradiction of stablecoins. They are systemically interesting before they are socially ordinary. They matter to markets before they matter to consumers. They are not yet money in the everyday sense, but they are already beginning to behave like a macroeconomic force.
That is especially true outside the rich world. Dollar stablecoins are increasingly a shadow channel for dollar demand. In countries where local currencies are weak, banking systems are fragile or capital controls are inconvenient, stablecoins offer a synthetic offshore dollar account. That may be useful for individuals and businesses. It may also be destabilising for domestic monetary systems. The more attractive the private digital dollar becomes, the more pressure it can place on local bank deposits, FX markets and sovereign monetary control.
This is why the regulatory conversation has hardened. The question is no longer whether stablecoins are innovative. Of course they are. The question is whether they are becoming important enough to require the old disciplines of money: backing, redemption, legal certainty, supervision and, eventually, public-sector anchoring.
Europe has drawn its own conclusion. The expansion of Qivalis, the bank-backed euro stablecoin consortium, shows that traditional finance no longer wants to watch from the balcony. The consortium plans to launch a MiCA-compliant euro stablecoin in the second half of 2026, with major European banks behind it and Dutch central bank supervision in view. This is not a crypto-native rebellion against the banks. It is the banks deciding they would rather build the stablecoin than be disintermediated by one.
That is an important shift. Stablecoins are not just tokens. They are a stack: fiat rails, custody, compliance, liquidity management, blockchain settlement, wallet infrastructure and distribution. The visible token is the least interesting part. The real battle is over who controls the orchestration layer beneath it.
The same logic is showing up in tokenised collateral. The fashionable language is about blockchain, but the institutional interest is far more practical. Banks, asset managers and market infrastructure firms are not mainly dreaming of decentralised utopia. They are trying to make collateral move faster, settle cleaner and work harder across fragmented markets. This is not the romance of crypto. It is the dull, lucrative business of reducing friction in financial plumbing.
There is a temptation to call all of this the maturation of digital assets. That is partly true. But it is also their absorption. The anarchic promise of crypto was that money could escape the state. The stablecoin reality is that the most successful private monies are now seeking recognition from it. They want banking access, regulatory legitimacy, institutional counterparties and, in the UK’s case, perhaps even a place on the central bank balance sheet.
That does not make stablecoins less important. It makes them more important. The future of digital assets may not be a world in which money floats free from public authority. It may be one in which private issuers, banks and central banks negotiate a new hierarchy of money, with stablecoins sitting somewhere between deposits, money market funds and settlement assets.
The UK has made its bet. It is not trying to win the stablecoin race by being the easiest jurisdiction. It is trying to win by being the one that institutional money can trust. That may look slow. It may look expensive. It may even look boring.
But in finance, boring has a habit of winning.
