Item	Detail
Body	Financial Stability Board (G20)
Report date	Oct. 12, 2026
Stablecoin market, start of 2025	About $206 billion
Stablecoin market now	$306 billion
Main concern	Multi-issuer structures, reserves trapped across borders
Binding?	No; members tend to implement agreed standards

The Financial Stability Board warned on Oct. 12 that global stablecoins and the national rules governing them have not been tested in a severe market crisis, and called for more cross-border information sharing, monitoring and planning for the distress or failure of an issuer. This crypto news digest item lands just before the G20 finance ministers and central bank governors meet on Oct. 15.

The core warning

In a report, the G20’s financial watchdog said national frameworks are developing at different speeds, which raises questions about how holders would recover funds if an issuer failed. Chair Andrew Bailey wrote in an accompanying letter that global stablecoin arrangements are “inherently cross-border” while cooperation in the area is “still in its infancy.”

The stablecoin market began 2025 at around $206 billion in capitalization and has grown to $306 billion, most of it in dollar-pegged coins. The FSB noted that much of the value is used to move in and out of crypto investments, though the tokens could eventually support faster and cheaper payments, including across borders.

Multi-issuer structures

The report singles out arrangements in which affiliated companies issue the same coin and share liability while holding reserves in separate jurisdictions. If holders can redeem with any issuer in the group, demand could pile up on one entity while the assets sit elsewhere. Moving reserves could be hard in a crisis, and it may be unclear whose insolvency law applies if an issuer fails.

Market structure risks

Stablecoins trade around the clock, but the markets for the assets backing them keep set hours. In a run, redemptions that cannot keep pace with selling could push a token off its peg. The FSB also acknowledged a counterweight: deep, liquid secondary markets can help pull a coin back toward its peg through arbitrage.

Forced reserve sales and bank deposit withdrawals could carry the shock into traditional markets as investors scramble for liquidity. Data is another weak point, since pseudonymous transactions make it hard to tell where holders are based and which jurisdiction applies.

Standing of the recommendations

The recommendations are not legally binding, but FSB members tend to commit to putting agreed standards into practice at home. Bailey, who is also governor of the Bank of England, has previously warned that international stablecoin rulemaking had stalled.

What to watch

Any reference to stablecoins in the G20 communique on Oct. 15 would show whether finance ministers want the cross-border planning to move faster. National regulators’ responses on multi-issuer models are the other thing to follow.
