The Bank of England has scrapped strict limits on how much retail investors can hold in stablecoins, replacing them with a £40 billion aggregate cap on total issuance. The move, paired with sweeter yield terms for token issuers, lays groundwork for a regulated stablecoin market the central bank plans to launch in 2027.
Why the cap replaces retail limits
Earlier proposals would have capped how many stablecoins any single user could hold — a restriction the BoE has now abandoned. Instead, the regulator will enforce a system-wide ceiling of £40 billion on all stablecoin issuance. That means no individual holding limits, but the total supply of regulated stablecoins cannot exceed that number.
The change is a clear shift in approach. The BoE is betting that a single, high aggregate cap is easier to police and less likely to stifle adoption than per-user limits. It also signals a broader willingness to let market forces determine distribution, as long as the overall size stays in check.
A $50 billion discrepancy
Confusion crept into early reports when some outlets, including the article that first flagged the news, pegged the cap at $50 billion. The official figure from the Bank of England is £40 billion — roughly equivalent at current exchange rates, but a different number nonetheless. The discrepancy appears to stem from a conversion used in the headline of an earlier report, not from any change in the policy itself.
The BoE has not commented on the mix-up. But the £40 billion figure remains the binding constraint for issuers looking to enter the UK market.
What sweeter yield terms mean for issuers
Alongside the cap, the central bank improved the economic conditions for stablecoin issuers. The details are sparse, but the move is widely read as an effort to attract serious players — banks, fintechs, and existing crypto firms — to build compliant stablecoins under the new framework.
Better yield terms could mean issuers are allowed to earn more on the reserves backing their tokens, or that they face lower capital requirements. Either way, the BoE is trying to make the math work for issuers who might otherwise prefer less regulated jurisdictions.
Timeline to 2027
The BoE says the new stablecoin market will go live in 2027. That gives the industry roughly three years to develop infrastructure, apply for licenses, and ensure their products meet the central bank's standards. The exact regulatory milestones between now and then have not been spelled out, but a consultation on final rules is expected within the next year.
For now, the message is clear: the UK wants a stablecoin regime that is big enough to matter but capped enough to contain risk. Whether £40 billion is the right number — and whether 2027 is realistic — are questions the market will test soon enough.
