TLDR
The Bank of England is designing limits on stablecoin use to protect the banking system while still trying to keep the UK attractive for digital finance.
- Early proposals used strict per-user caps, but the Bank is now leaning toward temporary guardrails on total stablecoin issuance instead of hard limits on each wallet.
- The rules focus on sterling payment stablecoins, with tight reserve and volume controls that could make UK tokens safer but less profitable than rival US dollar stablecoins.
- Draft rules are due soon, so issuers, exchanges, and DeFi builders should watch how far the Bank softens caps and reserve requirements, and how it coordinates with the FCA and Treasury.
Deep Dive
1. From Wallet Caps To Issuance Guardrails
The Bank originally floated caps of about 20,000 per person and 10 million per business in UK sterling stablecoins to avoid large deposit shifts out of banks during stress, drawing on lessons from past bank runs and liquidity crises. Multiple consultations describe these limits as temporary and aimed at systemic payment coins, not speculative trading tokens.
After strong industry criticism that such per-user caps would be operationally complex and stifle real-world use, Deputy Governor Sarah Breeden has signaled that the Bank is now considering temporary guardrails on the total volume of stablecoins that can be issued instead of per-holder caps, which could achieve similar risk control at lower cost to firms.
The core idea is not going away, but the form is changing from hard wallet ceilings toward system-wide issuance limits that are easier to supervise.
2. Impact On Issuers And Stablecoin Economics
Alongside caps, the Bank has pushed for conservative reserves. Current consultation language would require a large share of backing assets parked as non-interest-bearing deposits at the Bank, with the rest in short-term UK government debt, which industry argues makes UK stablecoins uneconomic compared with USDT and USDC that invest more heavily in Treasuries.
If the Bank sticks to high non-yielding reserve floors plus any hard issuance limits, pound-backed stablecoins will likely be safer but much less profitable to issue, so many firms may keep focusing on dollar tokens and offshore structures instead of launching fully onshore GBP stablecoins.
UK-focused payment and DeFi projects may get a clear, relatively safe regime, but the deep liquidity is still likely to sit in dollar stablecoins unless economics improve.
3. Timeline And What To Watch Next
Officials have said a refreshed draft rulebook for systemic stablecoins will be published in the near term, with final rules targeted around the end of 2026, alongside broader UK crypto and payments legislation.
Key variables to watch are:
- whether per-user caps are dropped entirely in favor of issuance guardrails,
- how low the non-interest-bearing reserve requirement is set, and
- how responsibilities are split between the Bank (systemic payment coins) and the FCA (other stablecoin uses).
For exchanges and protocol builders, those details will determine whether UK-regulated GBP stablecoins are viable for payroll, corporate settlement, and DeFi collateral, or remain a niche product.
Conclusion
The Bank of England is not backing away from controlling stablecoin risk, but it is pivoting from very rigid per-user caps toward more flexible issuance-based limits and revisiting harsh reserve rules. The eventual balance between safety and profitability will decide whether pound-backed stablecoins become a serious payment and DeFi rail in the UK or whether liquidity continues to concentrate in more lightly constrained dollar stablecoins overseas.
