FSB Warns Stablecoin Crisis Rules Remain Untested Across Borders

Stablecoin crisis rules have never been tested

The Financial Stability Board (FSB), the G20's financial watchdog, said stablecoins — digital tokens designed to hold a fixed value tied to a currency like the U.S. dollar — have never been tested during a severe market crisis. In a new report, the FSB called for stronger cross-border information sharing, monitoring, and crisis planning for stablecoins.

The stablecoin market began 2025 at roughly $206 billion in total capitalization and has since grown to about $306 billion, the FSB noted. Most of that value is tied to the U.S. dollar. While stablecoins are currently used mainly to move funds in and out of crypto investments, the FSB said they could eventually support faster and cheaper payments, including across borders.

What the FSB flagged

• National rules for stablecoins are developing at different speeds, and cross-border cooperation is still in its infancy.
• Multi-issuer structures — where affiliated companies issue the same stablecoin and share liability — can trap reserve assets in one country while redemption requests pile up on a different issuer.
• Stablecoins trade around the clock, but the markets for the assets backing them operate on fixed hours. That mismatch could cause a token to lose its peg during a redemption run.
• Pseudonymous crypto transactions make it hard to identify where holders are based or which country's rules apply.
• Forced reserve sales and bank deposit withdrawals could spread a stablecoin shock into traditional financial markets.

What FSB Chair Andrew Bailey wrote

In a letter accompanying the report, FSB Chair Andrew Bailey wrote that global stablecoin arrangements are inherently cross-border, yet national regulations are taking shape at different speeds and cross-border cooperation in this area is still in its infancy.

What is confirmed

The FSB published the report and Bailey's letter on October 12, 2026. The report confirms that global stablecoins have not faced severe stress or insolvency. It also confirms the market size figures of roughly $206 billion at the start of 2025 and $306 billion at the time of writing. The multi-issuer risk scenario and the 24/7 trading mismatch are documented concerns in the report.

What remains unclear

The FSB did not provide specific timelines for when cross-border information sharing agreements might be in place. It also did not identify which countries' frameworks are progressing fastest or slowest. The report notes that deep, liquid secondary markets could help restore a token's peg through arbitrage, but did not quantify how well that mechanism would work in a real crisis.

Why this matters for crypto users

If stablecoins become a standard way to move money across borders, the gaps the FSB identified could leave holders waiting — or unable to recover funds — during a real crisis. The report does not recommend against stablecoins. Instead, it asks regulators in different countries to share more information and plan together for the possibility that an issuer fails. Until those arrangements are tested, the uncertainty remains.
