UK and EU Rework Stablecoin Rules as Dollar Dominance Forces a Policy Reset

The UK and EU are both reworking stablecoin regulation as they try to keep innovation alive without handing the keys to the payments system to a handful of private issuers.

• UK and EU regulators are softening some of their toughest stablecoin proposals.
• Ownership caps, reserve rules, and yield bans are all under review.
• The U.S. is setting the pace, forcing Europe and Britain to rethink their positions.
• Christine Lagarde still distrusts stablecoins, but likes the blockchain rails underneath them.
• Euro stablecoins remain tiny, but bank-backed projects are pushing ahead anyway.

The stablecoin policy fight is getting sharper on both sides of the Channel. The Bank of England and the European Commission are revisiting parts of their frameworks as regulators try to balance financial stability, digital asset innovation, and the awkward reality that dollar stablecoins already dominate the market. Nobody wants a wild west money experiment, but nobody wants to be left using fax machines while the U.S. builds the next payments stack either.

UK stablecoin rules may be softened

The Bank of England is expected to publish draft rules for “systemic” stablecoins next month, with final rules due by year-end. Systemic stablecoins are the big ones — the kind that could affect the wider financial system if they fail or scale too quickly.

One of the most notable changes under discussion is the possible removal of ownership caps that had been floated at £20,000 for individuals and £10 million for businesses. Instead of limiting how much stablecoin someone can hold, the BoE is considering temporary guardrails on the total amount of a coin that could be issued.

“temporary guardrails on the total amount of a coin that could be issued”

That’s a major shift. Ownership caps were designed to stop stablecoins from growing into a shadow banking system overnight, but they also raised a very practical question: how do you enforce those limits without building a giant compliance machine that turns everyday payments into a bureaucratic slog?

The BoE is also considering whether banking groups should be allowed to issue stablecoins through non-deposit-taking, insolvency-remote entities — meaning legally separate structures designed to keep the stablecoin business insulated if the parent bank runs into trouble. In plain English: if the bank blows up, the coin business should not automatically get dragged under with it.

Reserve rules are also in flux. The BoE had previously floated a 40% reserve requirement held in unremunerated central bank accounts. That proposal was partly shaped by the 2023 collapse of Silicon Valley Bank and the temporary depeg of USDC, Circle’s dollar-backed stablecoin. When SVB failed, USDC briefly lost its peg because a chunk of its reserves were sitting at the bank. That was a neat little reminder that “stable” is a promise, not a law of physics.

Bank of England Deputy Governor for Financial Stability Sarah Breeden has described the goal as building “a multi-money system that promotes competition and choice between robust forms of money.” That sounds reasonable, and it is — provided the “competition and choice” part doesn’t become a polite way of saying “we’ll let innovation happen after we’ve wrapped it in enough tape to smother it.”

BoE Governor Andrew Bailey has been even more blunt. He warned of a “coming wrestle” with the U.S. over stablecoin standards, while also arguing that if global standards are aligned, the market can develop without fragmenting into regulatory chaos.

“a pound is a pound, whoever issues it.”

That line sums up the central bank mindset: if private money is going to circulate like money, it had better behave like money. Bailey’s warning about a “coming wrestle” is not dramatic theater either. The U.K. Treasury and U.S. Treasury have already launched a Transatlantic Taskforce on capital markets and digital assets, which tells you both sides know stablecoin policy is about to become a geopolitical tug-of-war.

EU stablecoin rules are under review too

The European Commission is also taking another look at MiCA, the EU’s Markets in Crypto-Assets Regulation. A public consultation is open until August 31, and it includes a review of some of the framework’s most controversial stablecoin provisions.

Those include the 60% local-bank reserve requirement for systemic stablecoins, the ban on stablecoin “interest or interest-equivalent remuneration,” and possible rules for stablecoins issued outside the EU. That last point matters because Europe does not want foreign-issued coins flooding the market without a clear legal footing. It’s a fair concern, but it also shows how much the bloc is trying to protect its monetary perimeter while the market keeps moving around it.

MiCA was supposed to give Europe a clear regulatory edge. Instead, the question now is whether the rules are too rigid for a market that is already being shaped by U.S. policy and by the sheer dominance of dollar-based stablecoins.

The market numbers are brutal. According to Artemis, USD stablecoins had a market cap of $322 billion in April, accounting for 99.76% of the total stablecoin market. Euro stablecoins, by contrast, were about $619 million in total — roughly 0.21% of the market. EURC accounts for about two-thirds of euro stablecoin supply, which means the euro’s digital money ambitions are still very much in the “startup with a dream” phase.

That imbalance is exactly why regulators are nervous. If the next generation of payment rails is overwhelmingly dollar-denominated, Europe risks ceding monetary influence to U.S.-linked infrastructure. That’s not just a crypto issue; it’s a sovereignty issue.

Christine Lagarde still wants the rails, not the coin

ECB President Christine Lagarde remains skeptical of stablecoins themselves, even while supporting the blockchain infrastructure that could support them. Her basic argument is simple: if the real benefit is fast, programmable, digital settlement, then do we actually need stablecoins to get there?

“do we actually need stablecoins to obtain the benefits they are said to provide?”

Lagarde has warned that stablecoins can suffer from “runs and redemption spirals,” which is central banking language for a very old and very ugly problem: if everyone rushes to redeem at once, the system can crack fast. She also said stablecoins may weaken monetary policy transmission, meaning central banks could lose some of their ability to influence the economy through interest rates and liquidity tools.

Her preferred alternative is tokenized commercial bank deposits for many wholesale use cases. Those are digital versions of bank deposits that can move on blockchain-style rails while staying inside the regulated banking system. That’s a much more ECB-friendly setup because it preserves control, oversight, and the traditional plumbing of finance.

“to pay with tokenized bank deposits, regulated stablecoins and, potentially, a retail central bank digital currency”

That line reflects the ECB’s broader vision: a mixed system of tokenized deposits, regulated stablecoins, and maybe a retail central bank digital currency down the road. In other words, the blockchain rails may be welcome, but the money still needs a chaperone.

There is also a devil’s-advocate case here. Regulators are not wrong to worry. Stablecoins can be useful, but they are not magic. They rely on reserve quality, redemption confidence, and market trust. If any of those wobble, the “digital cash” label can turn into marketing fluff very quickly.

Christoph Hock, digital assets chief at Union Investment, put it even more sharply. He said stablecoins “resemble hedge funds more than safe cash-like instruments” and warned of “catastrophic risk” for institutional investors if a major failure occurs.

“stablecoins resemble hedge funds more than safe cash-like instruments”

“catastrophic risk”

That may sound harsh, but the underlying point is real. Many stablecoins are backed by short-term assets and depend on redemption rights working smoothly under stress. If a large coin loses confidence, the run risk is not theoretical. It is the whole game.

Europe’s bank-backed euro stablecoin push is still alive

Despite the ECB’s skepticism, one major euro stablecoin effort is moving ahead. Qivalis, a bank-backed consortium, has expanded from 12 to 37 banks across 15 countries. Its members now include ABN Amro, Bank of Ireland, Spuerkeess, BNP Paribas, ING, and Raiffeisen Bank.

The group plans to launch its euro-denominated token in the second half of 2026, pending approval from De Nederlandsche Bank, the Dutch central bank. That is not a side project. It is a clear signal that major European banks do not want the future of digital payments left entirely to Tether, Circle, and a few crypto-native issuers.

“the case for promoting euro-denominated stablecoins is far weaker than it appears”

That skeptical view is easy to understand. If tokenized bank deposits can serve many of the same wholesale use cases, then why create another private token layer? But Qivalis is making a broader argument about control and infrastructure. Europe does not just want to copy someone else’s system; it wants to build its own rails.

“our task is not to replicate instruments developed elsewhere, but to build the foundations and the infrastructure that serve our own objectives”

“not just building a euro stablecoin; we are laying the European financial rails of the future.”

That is the real fight. Not just stablecoins, but who owns the rails beneath digital commerce. If U.S. stablecoins continue to dominate, Europe risks becoming a follower in a market that will shape payments, settlement, and perhaps even broader monetary influence. If Europe overcorrects with heavy-handed rules, it may choke off the very innovation it wants to protect. Pick your poison.

Why this matters for crypto and payments

Stablecoins are one of the few crypto products with obvious real-world utility. Traders use them to move quickly between exchanges. Businesses use them for settlement. Some people use them for payments and remittances because they are faster and often cheaper than traditional banking rails. That is why regulators care so much: stablecoins are not just a crypto side quest anymore. They are starting to look like financial infrastructure.

The problem is that financial infrastructure attracts financial regulation, and for good reason. The UK and EU are not banning stablecoins. They are trying to contain them, shape them, and prevent a future in which a privately issued token becomes too important to fail without any of the safeguards that traditional money has accumulated over decades.

That balancing act is messy. Too strict, and innovation gets pushed offshore. Too loose, and a bad reserve structure or a confidence shock could create a run that spills into the wider system. The Silicon Valley Bank episode showed how quickly confidence can evaporate. If the next crisis hits a much larger stablecoin, the consequences will not be funny, no matter how shiny the logo is.

The U.S. matters here because its more permissive stance is becoming the practical baseline for the market. If Washington sets a friendlier tone, stablecoin issuers and users may simply route around stricter jurisdictions. That is the “coming wrestle” Bailey is talking about, and it is not really about ideology. It is about where the liquidity, users, and standards end up.

For bitcoiners, there is a familiar lesson in all of this: the more permissionless and neutral the rails, the better. Bitcoin itself does not need a corporate issuer, a reserve manager, or a central bank to tell it what counts as sound money. But that does not mean stablecoins are useless. They fill a niche BTC was never designed to fill, especially in trading, settlement, and short-term digital liquidity. The problem is when those niche tools start pretending they are safe cash substitutes with no real trade-offs. That’s where the bullshit begins.

Key questions and takeaways

Are the UK and EU easing stablecoin rules?
Yes. Both are reconsidering some of the stricter ideas on ownership caps, reserve requirements, and yield restrictions.

Why are regulators worried about stablecoins?
Because large stablecoins can trigger runs, redemption stress, and wider financial instability if reserves or confidence break down.

Why does the U.S. matter so much?
The U.S. is setting a more permissive baseline, and that pressure is forcing the UK and EU to stay competitive or risk losing market activity.

Are euro stablecoins a serious market force yet?
Not yet. They are tiny compared with dollar stablecoins, but bank-backed efforts like Qivalis are trying to change that.

Does the ECB actually like stablecoins?
Not really. Christine Lagarde seems far more interested in blockchain infrastructure and tokenized deposits than in privately issued stablecoins.

Could tokenized bank deposits replace stablecoins?
In some wholesale use cases, yes. That is one of the main alternatives regulators are considering.

Will regulation kill innovation?
It could, if the rules get too heavy. But no serious stablecoin framework can ignore reserve risk, redemption rights, and the possibility of a run.

What is the biggest issue here?
Control of the payments layer. The fight is not just about stablecoins; it is about who sets the standards for digital money.

The UK and EU are trying to write rules that encourage useful digital payment systems without letting a new form of private money outrun the safeguards built around traditional finance. That may sound cautious, but in stablecoin land caution is not the enemy. Dumb complacency is. The next few months should show whether Europe and Britain can shape the market without smothering it — or whether the dollar stablecoin machine keeps eating everyone else’s lunch while regulators draft memos.
