Deep Dive

In a September 15, 2026 speech, Carolyn Wilkins used historical lessons from private money to argue that stablecoins can work at scale only with credible redemption, high-quality reserves, a consistent regulatory perimeter, and crisis liquidity arrangements. She previewed the Bank of England's stricter framework for systemic sterling stablecoins, due to be finalized at the end of 2026, and described the financial stability and geopolitical implications of dollar stablecoin growth. Compliance teams with stablecoin exposure should treat this as a signal of supervisory expectations on liquidity, reserves, and cross-border governance.

The key regulatory content concerns divergence between the US and UK regimes. The US GENIUS Act (July 2025) requires at least one dollar of eligible reserves per dollar issued, including Treasury securities, bank deposits, and other short-term liquid assets. It also strengthens disclosure and gives holders priority in insolvency. Wilkins notes that the Bank of England's framework for systemic sterling-denominated stablecoins is more demanding. It is more restrictive on reserve assets and places more weight on liquidity contingency planning, payment-system access, and failure arrangements. It also allows for central bank liquidity under appropriate conditions. The framework applies only to systemic stablecoins and will be finalized at the end of 2026. She also flags that the Federal Reserve's proposed limited-purpose account would give no access to emergency borrowing, and that consistency across US federal and state regimes remains an implementation challenge.

For compliance teams, the main exposures are cross-border and market-linked. A stablecoin may be issued in one jurisdiction, hold reserves in another, use a custodian in a third, and serve holders in many more. Redemption rights, insolvency treatment, supervision, and crisis responsibilities do not automatically travel with the token. About 98 percent of stablecoin value is dollar-denominated. USDT and USDC held almost USD $150 Billion of Treasury bills at the end of 2025, with net purchases of about USD $33 Billion that year. Wilkins warns that simultaneous redemptions could force reserve sales and amplify Treasury market stress, as seen in the 2022 UK LDI episode. She says the sector is not currently large enough to pose a material financial stability risk in the UK, but a major de-pegging could damage confidence in regulated stablecoins generally.

Recommended actions:
- Map stablecoin exposures, including issuer, reserve composition, custodians, banking partners, and redemption terms.
- Stress test liquidity and redemption assumptions.
- Monitor the Bank of England's final framework and compare it with GENIUS Act requirements to identify gaps for dual-jurisdiction activity.
- Update third-party and concentration risk assessments for issuers and reserve custodians.
- Review sanctions, AML, and operational resilience controls for payment flows that use alternative or digital rails.
- Brief senior management and risk committees on the speech's signals.

Impact is moderate and forward-looking. Near-term obligations are unchanged, but the end-2026 finalization date and the stated preference for stricter standards point toward higher expectations for UK-systemic stablecoin arrangements and for firms that rely on them.
