Bank of England sets $52B stablecoin cap

TLDR

The Bank of England has set a temporary issuance cap of about $52.8 billion per systemic sterling stablecoin, while scrapping earlier plans to limit how much each user can hold.

1. The new regime replaces per?user holding caps with a 40 billion (about $52.8 billion) issuance limit per systemic GBP stablecoin and relaxes reserve rules for issuers.
2. The cap is meant to manage bank funding risk while allowing households and businesses to use GBP stablecoins freely and making issuer business models more viable.
3. The framework targets final rules by late 2026 and a 2027 launch, and its impact will depend on which coins are deemed systemic and whether the cap is later lifted.

Deep Dive

1. What The Cap Actually Does

The Bank of England has abandoned earlier proposals to limit individuals to 20,000 and businesses to 10 million of a given sterling stablecoin, after strong industry pushback. Instead, it will impose a temporary issuance guardrail of 40 billion per systemic stablecoin, equivalent to roughly $52.8 billion, according to the draft Code of Practice and policy statement published on 22 June 2026.

Systemic stablecoins are defined as pound?pegged tokens widely used in payments that could threaten UK financial stability if they failed, and they will sit under BoE oversight, while non?systemic tokens used mainly for crypto trading stay with the Financial Conduct Authority. Multiple reports, including Bloomberg and Cointelegraph, confirm the new 40 billion ceiling and the removal of user?level caps as the core change in the UKs design for regulated GBP stablecoins.

2. Why It Matters For Stablecoin Issuers And Users

The BoE simultaneously relaxed reserve rules, letting issuers hold up to 70% of backing assets in short term UK government debt and the remaining 30% in non?interest?bearing central bank deposits, up from a previous 60:40 split. This makes it easier for issuers to earn some yield while still keeping reserves highly liquid, which several analyses highlight as important for commercial viability.

For users and businesses, the removal of wallet?level caps means they can hold large GBP stablecoin balances for payments, settlement and collateral without monitoring regulatory limits on each address. However, the issuance cap still prevents any single sterling stablecoin from growing beyond roughly $52 to 53 billion in supply, unlike US rules that avoid explicit caps on domestic?currency stablecoin issuance.

3. Timeline And What To Watch Next

The BoE describes the 40 billion issuance guardrail as temporary and plans to review it periodically, with an explicit aim to remove it once concerns about large deposit outflows from banks are addressed. The current timetable targets consultation through September 2026, final rules by the end of 2026, and the first regulated systemic GBP stablecoins operating in 2027.

Key open questions include which issuers HM Treasury designates as systemic, whether GBP stablecoins will be allowed for wholesale market settlement, and how quickly the cap might be raised or removed if adoption remains modest. Industry figures, including major exchanges, have welcomed the changes but warn that if the cap lasts too long, UK?issued stablecoins may lag dollar and euro competitors despite the friendlier reserve mix.

Conclusion

The Bank of Englands $52.8 billion issuance cap per systemic GBP stablecoin trades off growth in sterling stablecoins against protection of the traditional banking system. By scrapping user holding limits and easing reserve rules, the UK has made its framework more usable for both issuers and large users, while still keeping a hard ceiling on any single tokens size. The eventual importance of this move will hinge on whether UK regulators later relax the cap or keep it as a permanent brake on sterling?denominated stablecoin scale.
