Bank of England and FCA Set Out Joint Systemic Stablecoin Supervision Framework

The Bank of England and the Financial Conduct Authority have published their approach to the joint regulation of systemic stablecoin issuers in the United Kingdom. The document clarifies how the two authorities will coordinate supervisory responsibilities when a sterling-backed stablecoin achieves systemic scale, triggering dual oversight under the regime that came into force earlier this year.

The framework addresses division of labour: the Bank leads on prudential standards, liquidity backstops, and operational resilience, while the FCA remains primary for conduct, consumer protection, and anti-money laundering. A formal coordination mechanism is described for enforcement action, variation of permissions, and crisis intervention, with no single authority holding veto power. The approach applies only to issuers deemed systemic; smaller stablecoins remain under sole FCA supervision.

The publication moves systemic stablecoin regulation from theoretical possibility to supervisory reality. Any issuer approaching the systemic threshold now faces two sets of demands in parallel, with overlapping reporting calendars and no guarantee that both authorities will interpret the same risk event identically. The joint framework also implies that a systemic designation is a one-way door, since once triggered, the issuer remains under dual scrutiny even if market share subsequently contracts.
