Bank of England caps sterling stablecoin issuance

TLDR

The Bank of England will let users hold unlimited pound stablecoins but is capping each systemic token's total issuance at 40 billion under new rules.

1. The new framework replaces per?wallet limits with a temporary 40 billion issuance cap per systemic sterling stablecoin and eases reserve rules.
2. The cap is designed to prevent rapid deposit flight from UK banks while still making sterling stablecoins commercially viable and more competitive globally.
3. For crypto users, this opens the door to serious GBP stablecoins from around 2027, but growth is constrained if any coin ever nears the cap.

Deep Dive

1. What Exactly The BoE Has Changed

The Bank of England has dropped earlier plans to cap individual holdings at 20,000 per person and 10 million per business, and instead set a temporary 40 billion issuance cap for each systemic sterling stablecoin.

Issuers of these pound tokens can now hold up to 70 percent of reserves in short term UK government debt, up from 60 percent, with the remaining 30 percent as non interest bearing deposits at the Bank.

The rules apply only to systemic payment stablecoins that could matter for UK financial stability, while trading focused tokens stay under the Financial Conduct Authority. A final rulebook is targeted for late 2026, with launches expected from 2027, according to draft UK guidance.

2. Why The BoE Is Capping Issuance

The BoE frames the cap as a guardrail to stop very large pound stablecoins from draining deposits out of commercial banks too quickly, which could hurt credit and raise funding costs.

At the same time, removing user level limits and allowing more reserves in interest bearing gilts improves economics for issuers and makes sterling stablecoins more usable for payments and collateral.

Today, GBP stablecoins are less than 0.5 percent of global stablecoin supply, so the 40 billion ceiling mainly anticipates future growth rather than constraining the current market.

3. How This Affects Crypto Users And What To Watch

For users and businesses, the big win is unlimited balances, which removes a major obstacle to using GBP stablecoins in payments, on exchanges, and eventually in DeFi liquidity pools.

If demand for a regulated pound token ever pushes up against the 40 billion cap, scarcity effects could emerge, and the Bank has hinted it would review and possibly lift the ceiling once stability risks are addressed.

Key things to watch are which issuers seek systemic status, whether GBP stablecoins are allowed in wholesale settlement and major DeFi protocols, and whether the BoE actually relaxes the cap after the first phase.

Conclusion

The United Kingdom is moving from theory to a concrete regime where pound stablecoins can be large, fully regulated payment instruments, but not large enough to destabilize banks.

For crypto users, this sets up a credible GBP on chain option from around 2027, with clear rules on reserves and size. The long term impact will depend on whether the temporary cap is lifted as adoption grows.
