Bank of England Reconsiders Stablecoin Caps as GBP Tokens Face Dollar Competition

The Bank of England is rethinking parts of its stablecoin framework after crypto firms argued the original rules could smother pound-backed tokens before they get a fair run. The central bank is now weighing whether temporary holding caps and heavy reserve demands are too restrictive for a market it says it still wants to keep safe.

• BoE review: softer stablecoin rules are being considered
• Holding caps questioned: £20,000 per person, about $13.5 million for firms
• Reserve rules challenged: 40% at the BoE, earning no interest
• Global pressure: U.S. stablecoin policy is moving faster
• Big stakes: GBP stablecoins could help payments — or get steamrolled by dollar tokens

For anyone not living and breathing crypto jargon, a stablecoin is a digital token designed to hold a steady value, usually by being backed one-to-one with a fiat currency like the pound or the dollar, or by short-term government debt. In plain English: it’s money on blockchain rails, built to move fast without the wild price swings that make Bitcoin a terrible coffee token but an excellent long-term monetary asset.

The Bank of England originally proposed temporary holding caps on sterling stablecoins during an initial transition phase. Individuals would be limited to £20,000 in a single UK stablecoin, while corporate users would face a cap of around $13.5 million. The central bank’s logic was straightforward enough: if stablecoins became widely used for payments, deposits could pour out of commercial banks too quickly, creating stress in the banking system.

That fear is not imaginary. If a large chunk of everyday and business payments migrated from bank deposits to stablecoins overnight, commercial banks could lose a cheap funding source and face a messy adjustment. Regulators remember what happens when money rushes for the exits. Nobody wants to be the one standing next to a bank run muttering, “We should have seen that coming.”

But the crypto industry has pushed back hard, and the objections are not just ideological whining. Firms argue that holding caps would be difficult, if not outright impossible, to enforce across wallets, exchanges, and trading venues. Crypto does not run through one tidy central database where a regulator can flick a switch and say, “You’ve had enough stablecoin for today.” The whole point of the system is that it doesn’t work like that.

The reserve requirements have also drawn fire. The original consultation suggested issuers should keep at least 40% of reserves in non-interest-bearing deposits at the Bank of England, with the rest held in short-term UK government debt. On paper, that sounds conservative and clean. In practice, it means locking up a large chunk of customer funds at the central bank where it earns nothing. That is the kind of setup that can crush profitability and make a pound-backed stablecoin look less like a viable product and more like a regulatory museum exhibit.

That matters because stablecoin issuers still need a business model. If the rules make the product too expensive to issue or too awkward to operate, the serious players will go elsewhere. And if you make a market hard enough to use, guess what happens? Users don’t heroically suffer through it for the sake of national policy virtue. They route around it. Capital is rude like that.

Sarah Breeden, the Bank of England’s deputy governor, is now reviewing whether the holding caps are necessary and whether the reserve rules are too restrictive. Breeden has long been viewed as one of the more cautious voices on stablecoins, arguing they should meet standards comparable to traditional payment systems. That is a defensible position. Stablecoins can be useful infrastructure, but they are also money-like instruments that can create real risk if designed badly or left to scam artists and spreadsheet cowboys.

Still, caution is only useful if it doesn’t turn into self-sabotage. The Bank of England is trying to walk a narrow line: protect financial stability without making sterling stablecoins commercially dead before they even start. That’s a harder trick than central bankers usually admit.

The broader market backdrop makes the stakes obvious. Reuters cited CoinGecko data putting the global stablecoin market at more than $317 billion, and dollar-backed stablecoins still dominate that market by a mile. That is the uncomfortable truth for the UK: if pound-backed stablecoins are too difficult or expensive to launch, businesses will default to U.S. dollar stablecoins instead. They already have liquidity, scale, and a large user base. Money tends to go where the friction is lowest.

That is why the debate is about more than crypto trivia. Stablecoins are increasingly being used for payments, treasury management, and settlement. Treasury management means companies using digital assets to manage cash more efficiently. Settlement means the final transfer that actually completes a transaction. These are not moonboy use cases or speculative trading toys. They are the plumbing of modern finance, and whoever controls that plumbing gets a serious strategic advantage.

UK lawmakers are also examining how stablecoins should be regulated alongside future crypto legislation and possible plans for a digital pound. That raises a bigger question: does the UK want to encourage privately issued pound tokens, build a state-backed digital currency, or try to do both without tripping over itself? The answer will shape not just crypto policy, but the future of retail payments and cross-border money movement in Britain.

Andrew Bailey, the Bank of England governor and chair of the Financial Stability Board, has warned that global stablecoin oversight could trigger a difficult clash with the U.S. He said global payment use cases would require international standards and described the coming discussions with Washington as a “coming wrestle.”

“Coming wrestle.”

That’s a blunt way of saying the transatlantic policy gap is getting real. The U.S. is moving ahead with a more permissive stablecoin approach, including the GENIUS Act, which supports issuer regulation and broader stablecoin expansion. The Trump administration has also signaled support for stablecoins as part of America’s financial and geopolitical strategy. Translation: Washington seems more interested in shaping the market than strangling it.

The UK, by contrast, risks becoming the place where good ideas arrive wrapped in red tape and then quietly die in a committee room. That would be a bad outcome not just for crypto firms, but for British fintech, payments innovation, and the country’s long-term competitiveness. If sterling stablecoins can’t function at scale, then the pound loses another slice of relevance in the digital economy while the dollar extends its reach through blockchain rails.

There is also a deeper policy tension here that regulators keep running into. They want the benefits of innovation without the disruption, the safety of central control without the fragility of old infrastructure, and the competitive upside without any of the mess. Nice dream. Not how markets work. If the UK over-engineers this framework, the market will not politely wait. It will simply use dollar stablecoins, foreign issuers, or other jurisdictions with fewer handcuffs.

That does not mean the BoE should throw caution out the window and let any clown with a whitepaper issue a sterling token. Stablecoins absolutely introduce reserve risk, redemption stress, consumer protection issues, and the possibility of contagion if things are designed badly. The 2022 implosions across the broader crypto sector were a reminder that not all “innovation” deserves a medal. Some of it deserves a tombstone.

But there is a difference between smart guardrails and policy malpractice. If the UK wants a meaningful share of the stablecoin market, it needs rules that preserve trust without making issuance commercially pointless. A framework that is too restrictive may protect the incumbents in the short term while handing the future of digital payments to U.S. dollar tokens. That would be a very British own goal: cautious, polished, and deeply unhelpful.

For Bitcoiners, the takeaway is familiar. Stablecoins are not Bitcoin, and they are not supposed to be. BTC remains the cleanest sound-money asset in the room. Stablecoins, by contrast, are payment rails — useful for transfers, settlement, trading, and treasury operations, especially in markets that need speed and familiarity with fiat value. They each serve different niches. The real mistake is pretending one can replace the other.

What happens next may determine whether GBP-backed stablecoins become a useful part of the UK’s financial infrastructure or end up as a niche product while dollar stablecoins keep eating the market. The Bank of England is right to worry about systemic risk. It would be even wiser to worry about what happens if overcaution leaves the UK standing on the sidelines while everyone else builds the next layer of money.

What is the Bank of England reconsidering?
It is reviewing whether temporary holding caps on sterling stablecoins and the proposed reserve requirements are too strict.

Why were the holding caps proposed?
To reduce the risk of deposits leaving commercial banks too quickly if stablecoins became widely used for payments.

Why are issuers objecting to the reserve rules?
Because they would need to keep a large share of reserves at the Bank of England where the money earns no interest, which hurts profitability.

What would the reserve structure have looked like?
At least 40% of reserves would be held in non-interest-bearing deposits at the Bank of England, with the rest in short-term UK government debt.

Why does this matter for GBP stablecoins?
If the rules are too restrictive, pound-backed stablecoins may struggle to compete with dollar-backed stablecoins in payments and settlement.

How big is the global stablecoin market?
Reuters cited CoinGecko data valuing it at more than $317 billion.

What is the U.S. doing differently?
The U.S. is moving toward a more permissive framework, including the GENIUS Act, which supports stablecoin expansion.

Where does Bitcoin fit into all this?
Bitcoin is still the strongest decentralized monetary asset, while stablecoins are useful as fiat-denominated payment and settlement tools.
