The Financial Stability Board has issued a stark warning: three days before G20 finance ministers meet, the global financial watchdog has published an unequivocal report on the fragility of cross-border stablecoin regulatory frameworks. For the first time, a G20 body officially acknowledges that resolution mechanisms have never been tested under severe stress.
🔑 Key takeaways
- Stablecoin market cap rose from USD 206 billion in early 2025 to USD 306 billion by autumn 2026.
- Multi-issuer structures (USDC, USDP) concentrate legal and operational risks.
- No national regime has run a resolution drill for a global issuer under severe stress.
- BIS demands the “same business, same risks, same regulatory outcome” principle.
- The US Genius Act enters into force after July 2025 with three reserve scenarios.
A fast-growing market, fragmented regulatory frameworks
The FSB reminds stakeholders that stablecoins are inherently cross-border, while national regulations are advancing at very uneven speeds. According to Andrew Bailey, Governor of the Bank of England and Chair of the FSB, “cross-border cooperation in this area is still in its infancy”.
The scale of the phenomenon justifies the warning. Total capitalization jumped nearly 50 % in less than two years, with the vast majority still backed by the US dollar. Most of these tokens still serve as on- and off-ramps for crypto-asset investments, but the FSB notes they could eventually facilitate faster and cheaper cross-border payments.
| Indicator | Early 2025 | Autumn 2026 | Change |
|---|---|---|---|
| Total capitalization | USD 206bn | USD 306bn | +48.5 % |
| USD-backed share | ~99 % | ~99 % | stable |
| Main use case | Crypto on/off-ramp | Crypto + pilot payments | diversifying |
Multi-issuer structures: the system’s weakest link
The report identifies multi-issuer architectures as the most acute vulnerability. In these arrangements, several affiliated entities issue the same token and share responsibility, while holding reserves in different jurisdictions. The FSB explicitly cites Circle’s USDC and Paxos Global Dollar (USDP).
“Moving reserves may become harder during a crisis, and it may be difficult to determine which country’s insolvency rules would apply.”

The feared scenario is straightforward: in a run, holders redeem through the most accessible issuer, but the funds sit elsewhere. Cross-border transfers can then take several days, during which the token loses its dollar peg. A major legal complication compounds the operational risk: identifying the competent court and the applicable order of repayment in a cross-border insolvency.
A structural mismatch between 24/7 trading and traditional markets
Stablecoins trade continuously, while the assets backing them — government bonds, bank deposits — only trade during fixed hours. In a mass redemption event, custodians may not be able to liquidate reserves fast enough to honor requests.
The FSB tempers this concern: deep secondary markets can use arbitrage to push the token back toward parity. Systemic risk arises instead when forced sales spill over into traditional bond or banking markets, contaminating the institutions holding those reserves.
The FSB also highlights data opacity: the pseudonymous nature of crypto transactions makes it hard to locate holders and identify the competent jurisdiction — a weakness it calls a major problem for prudential oversight.
Genius Act: three reserve management scenarios
Adopted by the US Congress in July 2025, the Genius Act establishes a framework for “payment stablecoins”. Authorized issuers must guarantee a 1:1 peg to the dollar, holding exclusively bank deposits, short-dated US Treasuries, or balances at the Federal Reserve. Direct interest payments are banned, but indirect rewards remain possible.
| Scenario | Allowed reserves | Benefit | Risk |
|---|---|---|---|
| Bank deposits | Commercial bank accounts | Immediate liquidity | Bank risk exposure |
| Treasuries | Short-dated T-bills | Safety, yield | Forced sales in stress |
| Fed balances | Direct balances at the Fed | Zero credit risk | Monetary policy impact |
The Fed’s FEDS Notes from March 30, 2026 stress that the Federal Reserve may need to recalibrate its reserve management in the face of potentially large and volatile payment flows, in a context where more than 50 % of cross-border payments are denominated in dollars and travel through a shrinking pool of correspondent banks.
BIS insists on regulatory equivalence
The CPMI report from the Bank for International Settlements complements the FSB’s diagnosis. It notes that no stablecoin arrangement is currently considered “properly designed and regulated and fully compliant with all relevant regulatory requirements”.
BIS defends a cardinal principle: “same business, same risks or risk profile, same regulatory outcome”. Some jurisdictions flatly refuse stablecoins to protect monetary sovereignty, others prefer to regulate them to mitigate risks. This divergence complicates any attempt at a global approach and raises the risk of regulatory arbitrage between zones.
Conclusion: coordination time has come
The FSB does not issue binding rules, but its recommendations are usually implemented by members. The G20 session on October 15, 2026 will be a test: will finance ministers and central bank governors endorse a roadmap toward joint resolution plans, data-sharing agreements, and stress-test drills?
Watch four indicators: the conclusion of data-sharing deals between regulators, the publication of joint resolution plans, country-by-country disclosure of reserve locations, and stress redemption tests. Conversely, the absence of concrete measures in the coming months would signal that the warnings remain dead letter. As long as these tools are missing, the USD 300+ billion stablecoin market will remain a blind spot of the global financial system.
