Briefing
- The BoE's willingness to ease its stablecoin framework materially improves the economics for would-be sterling stablecoin issuers, reducing the risk that GBP tokens are issued from competing jurisdictions such as Dublin instead.
- Under the November 2025 consultation, individuals would have been capped at £20,000 in systemic stablecoin holdings and businesses at £10 million, while issuers would have been required to place at least 40% of reserves at the BoE interest-free.
- At short-dated gilt yields of approximately 4%, the 40% non-interest-bearing reserve floor would cost a UK issuer roughly £11.2 million per year for each £1 billion in circulation, according to Range CEO Andres Monty.
- Deputy Governor Sarah Breeden told the Financial Times the central bank would "look hard to see if we have been overly conservative in our thinking" on reserve requirements, citing SVB-era liquidity stress as the original rationale.
- Coinbase Europe policy head Katie Haries said "a cap on stablecoin holdings is a cap on innovation, with real and significant risks for UK competitiveness."
- The BoE is expected to publish revised draft rules before the end of June, with a final framework later in 2026; separately, BoE Governor Andrew Bailey has warned of a potential conflict with Washington over international stablecoin standards.
Analysis
- Removing the 40% non-interest-bearing reserve floor eliminates approximately £11.2 million in annual carry cost per £1 billion of GBP stablecoin in circulation, making UK-domiciled issuance economically viable for the first time. At current short-dated gilt yields near 4%, this cost was a direct subsidy to euro-denominated competitors operating from Dublin or Frankfurt. Issuers such as Circle and any prospective sterling stablecoin entrant now face materially lower barriers to UK licensing, reducing regulatory arbitrage pressure that had favoured offshore domicile.
- The BoE's regulatory relaxation, combined with Bailey's concurrent FSB warning about US stablecoin divergence, creates a two-speed dynamic: the UK competes for issuer domicile by easing reserve costs, while simultaneously resisting US-standard redemption terms that Bailey warned could trigger systemic run risk. Issuers seeking both UK and US distribution must now maintain parallel compliance structures, as Bailey's 'wrestle' framing signals the FSB will not converge down to GENIUS Act or CLARITY Act standards.
- The £20,000 individual holding cap, if retained in revised form, directly constrains GBP stablecoin utility for retail payment flows and limits network effects that drive stablecoin adoption. Even with reserve cost relief, a binding holding cap keeps UK-issued sterling stablecoins sub-scale relative to dollar equivalents with no comparable restriction, sustaining dollar stablecoin dominance in cross-border commercial flows that touch UK counterparties.
Historical Context
- Mar 2023
Silicon Valley Bank's collapse triggered a 72-hour $42 billion deposit run, the specific liquidity stress event Deputy Governor Breeden cited as the original rationale for the 40% non-interest-bearing reserve floor. The BoE now judges that floor was calibrated to SVB-era tail risk that may not apply uniformly to stablecoin reserve structures.
- 2022-2023
The EU's MiCA regulation established a reserve and holding-cap framework for euro-denominated stablecoins, prompting issuer domicile decisions across the UK-EU border. The BoE's original restrictive framework risked replicating MiCA's effect of concentrating issuance in Dublin and Luxembourg rather than London.
- 2021
China's DCEP rollout demonstrated that state-backed digital currency infrastructure can displace private stablecoin adoption domestically. The BoE cited similar concerns about systemic displacement risk when designing its original restrictive framework, a rationale now being partially unwound.

BoE Governor Bailey warns of regulatory conflict with US over stablecoin rules
BoE Governor Bailey's FSB warning that US stablecoin redemption terms could trigger systemic run risk in the UK directly tensions this regulatory easing: the BoE is simultaneously reducing issuer costs and resisting US-standard product terms, forcing cross-border issuers into dual compliance structures.
US Senate Banking Committee to mark up crypto CLARITY Act on May 14
The US Senate Banking Committee's May 14 markup of the CLARITY Act, which includes a provision banning yield on stablecoins, sets a divergent US product standard at the same moment the BoE is revising its own framework, compounding the compliance fragmentation Bailey warned about.

JPMorgan Asset Management's second tokenized money market fund launch on Ethereum, investing in US Treasuries and repo, illustrates the institutional infrastructure competing for the short-duration reserve asset flows that a viable GBP stablecoin market would require as backing collateral.
