The FCA set stablecoin capital at 1%, half MiCA's 2%. Systemic issuers must hold 30% at the BoE and 70% in short gilts. The safety bet is reserve composition, not equity.
Alpha Score of 57 reflects moderate overall profile with strong momentum, weak value, strong quality. Based on 3 of 4 signals — score is capped at 90 until remaining data ingests.
The FCA finalized a 1% own funds coefficient for regulated stablecoin issuers on June 22. EU rules under MiCA set the equivalent at 2% for asset-referenced tokens and e-money tokens. The gap is deliberate. London wants to attract issuance without diluting safety, the FCA said.
The Bank of England published its own framework the same day. Systemic sterling stablecoins must hold 1:1 reserves. At least 30% of that pool has to sit as deposits at the central bank. Up to 70% can go into short-term gilts with maturities of six months or less. A 5% excess buffer is allowed to cover daily redemption noise.
For own funds on systemic issuers, the floor is the highest of a £350,000 minimum, three months of fixed overheads, or 1% of coins in issue, called the K-SII factor, the joint BoE-FCA approach document said.
How Reserve Composition Replaces the Capital Gap
The headline gap between 1% and 2% attracted the most attention. A stablecoin's safety depends more on what the reserves are made of than on how much equity stands behind them. Central bank deposits convert to cash instantly. Short gilts can be sold or repoed quickly even in stressed markets. The 5% buffer absorbs timing mismatches when redemptions cluster.
MiCA asks for higher capital. It does not force the same reserve composition. The UK regime locks issuers into instruments that settle inside the state's balance sheet or within a hair of it. Capital is a second layer. Liquidity is the first.
One nuance hides below the percentage headlines. The UK capital calculation uses "coins in issue" as the base. The EU uses "average reserve assets." For a fully-backed stablecoin the two converge. The base matters if an issuer runs any gap between reserves and coins. The UK closes that gap by demanding 1:1 reserves before the capital floor applies.
Issuer Economics and the Operational Test
The immediate beneficiaries are prospective sterling stablecoin issuers. A 1% capital charge means roughly half the trapped equity compared to a MiCA launch. Several fintech wallets said they had been modelling with a 2% drag and recalculated when the 1% number landed. The gap between the two regimes is wider than the coefficient alone suggests, once the reserve requirements and redemption timelines are factored in.
Users could benefit if competition passes savings through as lower fees or better on-ramp pricing. That outcome depends on how many credible issuers enter and how distribution channels develop.
The real vulnerability is operational. Redemption speed, attestation cadence, and treasury scaling when flows spike on a risk-off day are the failure modes no capital ratio prevents.
What Would Confirm or Weaken the Setup
The UK approach works if a redemption under stress goes smoothly. A delay would weaken the case. Between those two outcomes, a few operational details determine the path. Redemption speed depends on whether gilts can be sold or delivered in hours, not days. Attestation frequency shapes whether users trust the reported reserve numbers. Regulatory coordination determines who responds first when a systemic issuer hits trouble.
The FCA oversees conduct and prudential compliance for non-systemic issuers. The BoE oversees systemic ones. Two rulebooks apply to one coin when a systemic issuer is active. The joint framework does not make explicit who calls the trigger during a run.
The Timeline from Here
The policy framework was finalized in late June. Implementation includes transitional arrangements that differ between the FCA and the BoE. Firms should confirm go-live dates against specific application milestones with both regulators before building a launch calendar.
The first systemic sterling stablecoin application has not been filed. The FCA and BoE said they will publish a list of authorised issuers as applications are approved.
None of this is financial advice. Stablecoins trade at par until the day they do not. Size for tail risk.
