The Financial Stability Board warned that the $300 billion stablecoin market could face redemption runs even with full reserves if reserves become inaccessible across borders. The market was valued at approximately $300 billion in mid-2026, with 99% of its value pegged to the US dollar. FSB Chair Andrew Bailey said authorities lack mature arrangements for managing cross-border stablecoin failures. G20 finance ministers and central bank governors will discuss the findings at the Oct. 15 meeting. The FSB seeks stronger monitoring, information sharing and crisis coordination, but has not established a timetable for common cross-border failure procedures.
