On October 12, 2026, the Financial Stability Board published a note for the G20 on cross-border vulnerabilities in global stablecoin arrangements. Its most useful contribution is a practical failure scenario: a token may circulate across borders every hour of the week, while the assets and legal entities backing its redemption are spread across jurisdictions with different banking hours, insolvency regimes and supervisory powers.
The FSB describes the global stablecoin market as approximately $300 billion in mid-2026, with around 99% pegged to the US dollar. Those are the report's historical estimates, not a live market-capitalization reading for October 13. More importantly, the board says these arrangements have not been tested through severe stress or the insolvency of a major issuer. The report is an analysis and monitoring document. It does not impose a new ban, licensing deadline or binding redemption rule.
A redemption request is more complicated than a blockchain transfer
Sending a dollar stablecoin from one wallet to another generally does not require banks to be open. Redeeming that same token for bank money does. The issuer must determine who has the legal right to redeem, access eligible reserves, pass operational and compliance checks and deliver fiat to the claimant.
Consider a hypothetical token that is distributed globally but issued by several affiliates. A holder in jurisdiction A wants immediate cash during a market panic. A reserve account sits with a bank in jurisdiction B, while the customer's contractual claim runs against an affiliate in jurisdiction C. A transfer onchain does not resolve which entity owes the dollars, whether the cash can legally cross borders, or what happens if one affiliate enters insolvency.
This is a scenario, not evidence of a current issuer failing. The FSB's concern is that an apparently unified global token could represent multiple redemption relationships that become visible only when liquidity is scarce.
Secondary-market liquidity can help—and then disappear
In normal conditions, market makers can buy discounted tokens and redeem them with an issuer, bringing exchange prices back toward the peg. That arbitrage depends on confidence in redemption, access to settlement banks and sufficiently deep market-maker balance sheets.
If issuers process fiat redemptions only during limited operating windows while exchanges continue trading around the clock, secondary-market prices may absorb stress first. A discount therefore does not prove reserves are missing. Equally, a token trading near $1 does not prove that every cross-border holder has an enforceable $1 redemption claim. Market liquidity and legal redeemability answer different questions.
The board also highlights data gaps. An issuer or supervisor may not know the identities and locations of all beneficial tokenholders, particularly when tokens circulate through intermediaries or self-hosted wallets. Transaction volume alone cannot reveal who would demand fiat under pressure, where their claims would be filed, or whether a single reserve pool could serve several jurisdictions simultaneously.
A diligence checklist for institutions
For a company holding stablecoins as treasury cash, the immediate questions should be contractual rather than promotional. Which legal entity guarantees redemption？ Is the institution itself an eligible direct redeemer or merely a secondary-market seller？ Where are reserves held and who can freeze or move them if the issuer fails？ Are segregated assets protected from claims against other affiliates？ What payment rails remain available on weekends and bank holidays？
An institution should also ask which exchanges and dealers can absorb a large sale, whether any concentration of inventory creates a single liquidity bottleneck, and how rapidly the issuer publishes independently useful reserve information. None of these checks can be inferred from a token's nominal dollar peg alone.
What the FSB paper does—and does not—establish
The report supports stronger monitoring, cross-border cooperation and crisis planning. It does not quantify a probability of collapse, establish that a named stablecoin is undercollateralized, or test whether a specific issuer can survive simultaneous international redemptions. The roughly $300 billion market estimate should not be treated as the amount immediately at risk in any one event.
The next substantive signal would be jurisdiction-specific disclosure rules, cross-border supervisory agreements or an issuer publishing enforceable details on redemption priority and reserve mobility. A stablecoin's design is proven less by how quickly it can travel in normal markets than by how clearly its holder can obtain fiat when market makers stop bidding.
