Global watchdog warns stablecoin risks cross borders as G20 finance leaders meet

Global regulators are worried about what happens when a big stablecoin breaks. On October 12, the Financial Stability Board, the watchdog that coordinates financial rules for the G20, published a report warning that stablecoin risks cross borders in ways no single country is ready to handle. Its chair, Bank of England Governor Andrew Bailey, told G20 finance leaders that cooperation on the issue "is still in its infancy."

The report lands just before G20 finance ministers and central bank governors meet on October 15, according to CoinDesk. For Americans the timing matters. Nearly all stablecoin value is tied to the US dollar, and Washington is in the middle of writing its own stablecoin rules. Here is what the FSB found, what it wants, and what it means for people who hold or use these tokens.

What the FSB report says about stablecoin risks

The report is titled "Global Stablecoin Arrangements: Cross-border vulnerabilities and financial stability monitoring." It looks at stablecoins that operate in many countries at once, which describes the biggest tokens on the market.

According to the FSB, stablecoins had a total market value of roughly $300 billion as of mid 2026, and about 99% of that value is pegged to the US dollar. The board says the tokens are still used mainly for trading inside crypto markets, though in some emerging and developing economies they also work as a store of value and a way into the financial system. CoinDesk, reading the same report, described a market that has grown from about $206 billion at the start of 2025.

The core worry is simple. A global stablecoin issuer may not know who holds its tokens or where redemption requests will come from. The FSB calls these liabilities internationally mobile and partly unobservable. In plain terms, money can flow in from anywhere, and it can rush out from anywhere too.

The run problem

Stablecoins trade around the clock. The bonds and bank deposits that back them do not. The FSB warns that in a crisis, nonstop trading on secondary markets could speed up a sell off and push a token off its $1 peg before the issuer can sell reserves to meet redemptions. The board does note one cushion: deep, liquid secondary markets can help restore a peg through arbitrage.

A run would not stay inside crypto. The report says stress could spill into the markets for reserve assets, into bank deposits, into payment systems and into foreign exchange markets. CoinDesk described the risk of forced reserve sales spreading the shock into traditional finance as investors scramble for cash.

The multi issuer problem

Some stablecoins are issued by several affiliated companies in different countries that share liability for the same token. If holders can redeem with any of them, demand can pile up at one entity while the reserves sit somewhere else. The FSB warns that moving reserves across borders to cover that gap may fail under stress.

Unclear rules when an issuer fails

The report also flags legal gaps. Countries are writing rules at different speeds, which the FSB says has opened room for regulatory arbitrage. If an issuer goes bust, it may not be clear which country's insolvency law applies, which makes it harder for holders to know how and when they get their money back. The FSB adds that most frameworks have never been tested in severe stress.

What the watchdog wants

The FSB is not proposing a new rulebook. Instead, it lays out three areas of work to put its 2023 stablecoin recommendations into practice:

1. Stronger monitoring of cross border vulnerabilities, using new indicators proposed in the report.
2. More cooperation and information sharing between national authorities.
3. Gathering information on how authorities plan for a stablecoin in distress or outright failure, with a focus on cross border issues.

It also calls for better data. Regulators lean heavily on private data firms whose methods vary, and the pseudonymous nature of public blockchains makes it hard to tell where holders are or what they use tokens for. The FSB suggests building shared monitoring metrics, pooling analysis across borders and studying industry best practices for on chain and off chain data.

These recommendations are not legally binding. FSB members usually commit to carrying out agreed standards in their own countries, but the report sets no deadlines.

Bailey's warning to the G20

In a letter to G20 finance ministers and central bank governors dated October 8, Bailey said treatment of foreign issued stablecoins is unclear in many jurisdictions. He wrote that tools for cross border oversight, crisis management and resolution "remain immature or are not yet developed." He also tied stablecoins to fraud and financial crime, especially in lightly regulated places.

The same letter covered artificial intelligence, urging the G20 to "champion" the FSB's sound practices for responsible AI adoption by financial firms.

Why it matters in the US

Dollar stablecoins are, in effect, a private extension of the dollar around the world. That makes US rules central to everything the FSB describes. American regulators are racing to finish stablecoin rules under the GENIUS Act, and the questions the FSB raises, such as how foreign issued tokens are treated and what happens in an insolvency, are the same ones those rules will need to answer.

Stablecoins are also spreading into everyday apps. Samsung recently added USDC transfers to Samsung Wallet for Galaxy phone owners in the US. The more ordinary people hold these tokens for payments, the more a run would hurt people outside crypto trading. Federal policy has not moved in one direction only, either. Treasury recently dropped a proposed rule on crypto mixers and unhosted wallets, a reminder that the data gaps the FSB describes are partly a policy choice.

Who is affected, and what to do

If you hold stablecoins, nothing changes today. The report does not ban or restrict any token. But it is a useful reminder of what you actually own. A stablecoin is a claim on a private company, not an insured bank deposit. If you need a refresher, our guide to how stablecoins hold their $1 value covers the basics.

A few sensible habits:

• Know which company issues your stablecoin and where it is regulated.
• Read the issuer's reserve reports and check how often they are published.
• Understand the redemption terms, including fees, minimums and who is allowed to redeem directly.
• Keep amounts you cannot afford to have frozen in insured accounts, and learn how crypto wallets work before moving large sums.

What to watch next

The next step is the G20 meeting on October 15, where finance leaders will receive the FSB's work. Watch for whether national regulators commit to the information sharing the board wants, how US rules treat foreign issued dollar tokens, and whether the FSB's new monitoring indicators show up in official reports next year.

Frequently asked questions

What is the Financial Stability Board?

It is an international body that coordinates financial regulation for the G20 economies. Bank of England Governor Andrew Bailey currently chairs it.

Does the FSB report ban stablecoins?

No. It recommends more monitoring, information sharing and crisis planning. Its recommendations are not legally binding, though members usually adopt agreed standards.

How big is the stablecoin market?

The FSB put total stablecoin market value at roughly $300 billion as of mid 2026, with about 99% pegged to the US dollar.

Why is a stablecoin run a concern?

Stablecoins trade 24/7 while their reserve markets do not, so a fast sell off could break the $1 peg and spread stress into banks, bond markets and payment systems.
