What happened
Bailey's intervention, reported Saturday by Crypto Briefing, focuses on a structural mismatch. The largest stablecoins in circulation are dollar-pegged and issued by firms based in the US or offshore, while a meaningful share of trading, custody, and payments flow runs through London. If reserves at a major issuer hit a stress event, the run dynamic plays out across jurisdictions, and the BoE inherits second-order damage through UK-domiciled market makers, exchanges, and custodians it does supervise.
Bailey called for global regulatory coordination to mitigate that contagion risk, framing the issue as a financial stability question rather than a punitive one. The remarks raise the temperature on a debate UK regulators have been managing in writing for the better part of two years.
Why it matters
The UK has spent the past two years drafting a domestic stablecoin regime, with the Treasury, the Financial Conduct Authority, and the Bank dividing oversight between systemic and non-systemic issuers. That framework assumed the supervisory contour ends at the British perimeter. Bailey is saying it doesn't.
Most stablecoin volume touching London is denominated in dollars and regulated under US or offshore rules, which leaves the UK exposed to issuer failures it cannot directly police. The Bank's lender-of-last-resort role applies to UK institutions. It does not extend to a US issuer's reserve manager, custodian, or banking partner.
That gap is what Bailey's warning is built around. The political read: Bailey wants coordination, not a ban, but he is staking a UK position with weight at a moment when dollar stablecoins have more federal cover in Washington than at any prior point.
