The Financial Stability Board has warned G20 finance ministers and central bank governors that cross-border arrangements for overseeing global stablecoins remain immature and largely untested in a severe market crisis or insolvency. In a letter and accompanying report published on October 12, 2026, the watchdog called for enhanced information sharing, monitoring and advance planning for distress or failure of these tokens.

FSB Chair Andrew Bailey submitted the materials ahead of the G20 finance ministers and central bank governors meeting scheduled for October 15. The board said global stablecoins, whose value is pegged to a fiat currency, operate across multiple jurisdictions and sectors, yet national regulatory frameworks are advancing at uneven speeds.

Multi-Issuer Structures and Spillover Risks

A central concern centers on arrangements in which affiliated companies jointly guarantee or issue the same stablecoin. In such cases, redemption demand could concentrate on a single issuer while the reserves that back the token sit in different jurisdictions. This mismatch would complicate any emergency response and could delay holders’ ability to redeem at par.

The FSB also noted that stablecoin markets trade continuously while the markets for the underlying reserve assets follow conventional schedules. During stress, the timing gap could accelerate forced sales of those assets. Pseudonymous transactions add a further obstacle by making it harder for authorities to identify holders, liabilities and the relevant jurisdictions quickly.

A run on a major stablecoin could transmit pressure beyond crypto markets. Issuers might be forced to liquidate reserve holdings, while holders could withdraw bank deposits, creating liquidity strains in traditional finance. As of mid-2026 the stablecoin sector had a combined market value of approximately $300 billion, with 99 percent of that value pegged to the U.S. dollar.

Progress on Regulation Remains Uneven

In a 2025 review the FSB found that only 11 of 28 surveyed jurisdictions had finalized regulatory frameworks for stablecoins. The board’s recommendations, which are not legally binding, build on its 2023 guidance that called for cross-border cooperation, data access, recovery and resolution plans, and timely redemption at par for single-fiat stablecoins.

Authorities are urged to improve monitoring of cross-border vulnerabilities, share information more systematically and conduct further work on how to manage the distress or failure of a global stablecoin arrangement.

AI Risks and New Safeguards

Alongside the stablecoin assessment, Bailey urged G20 members to support the FSB’s newly finalized sound practices for the responsible adoption of artificial intelligence in the financial sector. The practices address organization-wide governance, the development and deployment of AI systems, cybersecurity and risks arising from third-party service providers.

Bailey noted that sophisticated cyber threats enabled by AI could undermine the resilience of critical financial institutions and market infrastructure. The FSB had proposed twelve practices in June and completed the guidance in time for the October G20 meeting.

The letter and reports form part of a broader package the FSB is delivering to the G20, covering also private-credit vulnerabilities, public-sector backstop funding and regulatory modernization. The board stressed that new technologies and shifting market structures create opportunities but also demand vigilance and international cooperation.
