TLDR
The Bank of England proposed a new regime for sterling?denominated systemic stablecoins with reserve rules, temporary holding caps, and split oversight between the BoE and FCA, now out for consultation. See the outline in a detailed coverage.
- Temporary caps per coin: 20,000 for individuals and 10 million for businesses, intended to be lifted as risks subside, per a report.
- Reserves split: at least 40% as non?interest deposits at the BoE, up to 60% in short?term UK government debt, with a launch allowance up to 95% gilts, per coverage.
- Scope and timing: applies to systemic GBP payment coins while trading?use tokens stay under the FCA; consultation runs to 10 Feb 2026, per this summary.
Deep Dive
1. Holding Caps
The BoE proposes temporary per?coin limits of 20,000 for individuals and 10 million for businesses to manage deposit?flight risk in the early adoption phase, with exemptions for large operational users and plans to lift caps once stability risks fade, per a report.
- The caps are framed as transitional safeguards during a shift to digital money rather than permanent constraints, according to the same report.
- Media also note these caps and the BoEs softer stance than in 2023, while still more conservative than the U.S., per coverage.
Users may need to spread balances across coins or venues during the transition. Large businesses could seek exemptions to avoid operational friction.
2. Reserve Backing and Liquidity
Issuers of systemic GBP stablecoins must hold at least 40% of liabilities as unremunerated BoE deposits and up to 60% in short?term UK government debt, with a temporary allowance up to 95% gilts for early scaling, per coverage.
- The BoE is considering liquidity backstops for systemic issuers in stress as a market backstop, according to a separate summary.
- This represents a moderation from earlier ideas that leaned toward 100% central?bank deposits, as noted in multiple reports.
Issuers economics will rely on gilt yield net of the 40% non?yielding BoE portion, which could shape fees, spreads, and which firms can viably launch GBP payment coins.
3. Scope, Oversight and Timeline
Only systemic GBP stablecoins used at scale in UK payments fall into the BoE regime; HM Treasury designates systemic status, the BoE handles prudential and stability risks, and the FCA handles conduct, per this outline.
- Non?systemic stablecoins used mainly for trading (for example, USDT or USDC on exchanges) remain under the FCA and are not subject to the new caps, per the same outline.
- Consultation runs to 10 Feb 2026 with final rules expected in H2 2026, per a separate summary. Industry reaction sees progress but still calls the stance cautious, per commentary.
Trading?focused stablecoin use in the UK should be largely unchanged near term, while GBP payment stablecoins face a clearer but stricter path to scale under BoE oversight.
Conclusion
The BoEs proposal blends caution with pragmatism. Caps reduce early?phase deposit?flight risk, while a 40% BoE deposit plus 60% gilt reserve model and potential liquidity backstops aim to keep systemic GBP stablecoins safe at scale. For most crypto users focused on trading pairs, near?term effects look limited as those tokens remain under the FCA, but GBP payment coins will operate under tighter, bank?like standards once the rules are finalized.
