Bank of England sets $53B stablecoin cap

TLDR

The Bank of England will allow regulated pound stablecoins to grow up to about $53 billion each, while scrapping earlier limits on how much any one user can hold.

1. The new framework replaces wallet-level caps with a temporary 40 billion (around $53 billion) issuance ceiling per systemic GBP stablecoin.
2. Issuers get more flexible reserves and yield, but GBP stablecoins still sit below top dollar rivals and face a hard growth guardrail.
3. The regime is set to go live around 2027, and future reviews of the cap and use in wholesale markets will decide how competitive UK stablecoins become.

Deep Dive

1. What Exactly The BoE Decided

The Bank of Englands June policy statement introduces a temporary issuance limit of 40 billion per systemic sterling stablecoin, roughly $52.853 billion at current rates, while deleting earlier per-user caps of 20,000 for individuals and 10 million for businesses. Instead of tracking every wallet, supervisors will monitor the total supply of each designated systemic pound token as a simpler stability tool. Multiple reports summarize the move as a shift from user caps to a system-wide issuance guardrail that can be reviewed and eventually removed as risks to bank credit are better understood.

2. Impact On Issuers And Market Structure

The cap only applies to sterling tokens judged systemic in payments, not every experimental or trading-focused stablecoin, giving room for smaller issuers while constraining the largest. The rules also relax reserves: issuers can hold up to 70% of backing assets in short-term UK government debt, with the rest in non-interest-bearing central bank deposits, improving business viability while keeping high-quality backing. Still, a single GBP stablecoin capped near $53 billion would remain far smaller than major dollar stablecoins such as USDT and USDC, so the framework permits meaningful growth but deliberately avoids a pound token matching the largest dollar coins in size.

3. Timeline And What To Watch Next

The BoE aims to finalize the rulebook by late 2026, with systemic sterling stablecoins operating under the new regime from 2027, alongside parallel oversight by the Financial Conduct Authority. Comment periods and industry lobbying could influence how temporary the 40 billion guardrail really is, whether the ceiling is raised, and whether these tokens can be used for wholesale settlement in core financial markets. If UK demand for regulated pound stablecoins ever approaches the cap, you could see either pressure to lift it, multiple GBP tokens sharing the market, or continued dominance of offshore dollar stablecoins.

Conclusion

By swapping individual holding caps for a roughly $53 billion issuance ceiling per token, the Bank of England is signaling that it wants serious, regulated pound stablecoins, but not without size limits. The balance between innovation, bank funding stability, and competitiveness with dollar and euro stablecoins will depend on how quickly demand grows and whether regulators ultimately relax or harden this temporary cap.
