Financial Stability Board on 300 billion dollars in stablecoins: “untested in severe stress and insolvency”

The Financial Stability Board delivered a status report on stablecoins to the G20 on 12 October 2026, and its central finding is an uncomfortable one: “Global stablecoins and national regulatory frameworks remain untested in severe stress and insolvency.” That is not a description of an acute problem today, but of an open flank. Nobody knows what happens when a large issuer fails and holders in dozens of countries want their money back at the same time.

If you hold stablecoins in Germany, this is not an abstract debate from Basel. Stablecoins are the short-stay car park of the crypto market: almost every trade runs through them, withdrawals go through them, and investors locking in a gain swap into them. The report sets out where that construction is thin, and it names what supervisors cannot currently measure. This article sorts the points and says which of them European law already settles.

What the Financial Stability Board sent to the G20 on 12 October

The Financial Stability Board (FSB) is the body in which the central banks, finance ministries and supervisory authorities of the large economies coordinate their regulation. It does not pass laws. It drafts recommendations that member countries then cast into law of their own.

On 12 October 2026 the body published the nine-page note “Global Stablecoin Arrangements: Cross-border vulnerabilities and financial stability monitoring”, together with the letter from its chair, Andrew Bailey, to G20 finance ministers and central bank governors. Their meeting takes place on 15 October 2026 in Bangkok. Alongside the stablecoin note, the round also received a peer review on public backstops, a consultation report on modernising supervision and the finalised principles on the use of artificial intelligence.

What the note is and what it is not

The note describes itself as a summary of work in progress, not as a final policy decision. It builds on the FSB recommendations of 2023 and on the 2025 review of how they have been implemented. Three questions sit at its centre: how are these arrangements built? Along which paths could problems spread? And which metrics would supervisors need in order to see that in time?

$300 billion in stablecoins, 99 percent of it pegged to the US dollar

The report gives two figures for the scale. At mid-2026 the total market value of all stablecoins stood at around $300 billion, practically unchanged from the year before. And 99 percent of that value sits in tokens pegged to the US dollar.

The second figure is the more interesting one. In plain terms it means that a European investor holding stablecoins is almost always holding dollar risk. Park in a dollar token for months and you carry the move in the euro-dollar rate with it, without that being disclosed anywhere. A token that is stable against the dollar is anything but stable against a current account in euros.

The report also records what stablecoins are actually used for today: mostly as liquidity, to move into crypto markets and back out again. In emerging and developing economies a second role is added, as a store of value and as access to financial services. Everyday use in the real economy is something the body calls a possibility for the future, not the state of play today.

Global stablecoin: the term as the FSB report defines it

Under the body’s 2023 definition, a global stablecoin is a stablecoin that is distributed and used across several jurisdictions and could become systemically important in one or more of them. Systemically important means large enough and interconnected enough that its failure drags other parts of the financial system down with it.

That crossing of borders is the core of the problem the note describes. A single supervisor only ever sees its own section. The issuer sits in country A, the reserves lie in country B, trading happens on exchanges in country C, and the holders are spread across the whole world. None of these authorities has the complete picture, and the activities around such a token are spread across different types of firm as well, each with its own supervisor.

Why an issuer does not know its own holders

A bank has an account and therefore a name for every depositor. It knows how much money can be withdrawn at short notice and manages its balance sheet accordingly. A stablecoin issuer has no such view. The report puts it soberly: it may not know who holds its liabilities, where those holders are resident, and in which country redemption will eventually come knocking. The liabilities are internationally mobile and in part simply unobservable.

Multi-issuer structures: when redemption shifts onto a single issuer

One case the note singles out is the multi-issuer arrangement. Several affiliated companies issue the same token and are jointly liable for it, but each holds its own reserves in its own jurisdiction. To a holder it looks like a single token, and it can be redeemed with any of those companies.

In normal operation that works, because the companies move reserves between themselves and the secondary market evens out the differences. Under stress, that balancing act rests on four conditions the report names one by one: the reserves must be mobile, the markets accessible, the information must flow, and the companies involved must coordinate. If one of those falls away, redemption concentrates on a single company while the money sits elsewhere.

A legal question hangs on this that nobody has answered so far. If it cannot be established where the holders sit, it is also unclear which liability belongs to which company. In insolvency that turns into the question of which national insolvency law applies at all. The report writes that this could in some circumstances prove difficult. That is supervisory language for unresolved.

Tradable around the clock, redeemable only in market hours

A second fault line lies in time. Stablecoins trade on secondary markets around the clock, on every day of the year. Redemption into real money and the management of the reserves, by contrast, run through traditional markets, with their opening hours and settlement conventions, and increasingly under regulatory requirements.

Under stress that gap works as an amplifier. Selling pressure can build in hours when the reserve side cannot act at all. If redemption fails to keep up with demand, the peg to the dollar comes under pressure. The report names the counterforce as well: deep and liquid secondary markets allow arbitrage that can pull the price back to the peg.

What a depeg means technically

A depeg is the moment when a stablecoin loses its peg and trades below its nominal value on the market, at 97 cents instead of a dollar, say. In law the claim to redemption at full value continues to exist, provided the issuer can pay. In practice, only those who can enforce redemption directly with the issuer receive the full value at that moment. Everyone else sells on the market, at the market price.

From depeg to bank: how a run jumps across to the financial system

The report describes four transmission channels along which a run on a large stablecoin reaches the traditional financial system. First, the issuer has to sell reserve assets to meet redemptions, quickly and in size, which pushes the prices of those assets down. Second, it withdraws deposits from banks to raise liquidity. Third, it hits everyone who needs the token for payment and settlement in the real economy. And fourth, foreign exchange markets move with it, wherever stablecoins are used for cross-border payments.

Emerging and developing economies are hit particularly hard, the report says. There, currency substitution, meaning the displacement of the domestic currency, the bypassing of the banking system and difficulties in managing capital flows are added to the list. A stablecoin can become systemic there at far lower adoption than in the euro area.

The quality of the reserves and the supervisory regime an issuer works under remain the decisive lever. An issuer holding illiquid or low-grade assets in a country that has not implemented the 2023 recommendations sharpens both problems at once, liquidity and day-to-day operations. To see which supervision your trading platform works under, the overview of crypto exchanges licensed in Europe helps more than any reserve report from an issuer.

Regulatory arbitrage: issuers sit in weakly regulated countries

One finding in the note is politically delicate and therefore remarkably openly worded. The interaction of national rulebooks has produced complex cross-border structures and opened up opportunities for regulatory arbitrage; some issuers have chosen to operate out of weakly regulated or unregulated jurisdictions. Regulatory arbitrage means deliberately picking a location for its laxest supervision.

At the same time the body pushes back against the reflex of deriving a single solution from this. No one-size-fits-all approach exists, it says; countries implement the recommendations within their own mandates and legal orders. How those frameworks mesh remains complex and uncertain. And that is where the sentence that gives this article its headline comes from.

The data gap: supervisors rely on private data providers

The second part of the note deals with something that almost never comes up in the public debate: how do authorities actually know what they think they know about stablecoins? The answer is sobering. Supervisors rely for the most part on private data providers, which filter and aggregate raw blockchain data with their own, in part undisclosed, methods. Those methods differ in accuracy and transparency, and different providers arrive at different results.

One hurdle can barely be removed, in the body’s assessment. Public blockchains are pseudonymous, and the smart contract infrastructure behind most stablecoins gives no information about what a token is used for or where. Attribution by use or by country is therefore often impossible; where it is possible, it cannot be verified, because the methods are inconsistent and in part secret.

Yet that attribution is precisely what the note asks for in order to monitor the market: the depth, liquidity and structure of secondary markets, plus the geographical distribution of holdings, redemptions and reserves, with particular attention to the multi-issuer arrangement. What is being demanded, then, is a measurement that the same note explains cannot currently be delivered. For the coming months the report names three steps: develop metrics and identify data gaps, make better use of the data that already exists, and examine industry standards for collection.

MiCA in Germany: the legal framework for holders is already in place

At this point it is worth looking to Europe, because much of what the report treats as an open question has already been answered here. The EU regulation on markets in crypto-assets, MiCA for short, places stablecoins under a regime of their own. Tokens that reference a single official currency count as e-money tokens and may only be offered publicly in the EU by authorised electronic money institutions or credit institutions. For tokens that reference a basket of values, the rules for asset-referenced tokens apply.

Obligations hang on this that address precisely the weak points in the FSB report: the reserves must be held separately from the issuer’s own assets, holders have a claim to redemption at par value, and the issuer needs authorisation from a European authority. In Germany that route runs through BaFin, the federal financial supervisory authority. Our overview of the MiCA obligations for crypto companies sets out which duties those are in detail.

What that means for the tokens in your account

In practice, not every stablecoin traded on an international exchange may also be offered to European customers. Several trading venues have reorganised what they offer EU customers for that reason; we reported on the ESMA deadline for exiting non-authorised tokens on 8 October 2026. Anyone holding stablecoins today should know which category their token falls into, before a trading platform makes that decision for them.

Tax and custody: two points for stablecoin holders in Germany

Two things regularly get lost in the regulatory debate, even though they affect holders directly.

The first point is tax. For tax purposes a stablecoin is not a euro. Swapping a coin into a stablecoin is a disposal within the meaning of section 23 of the German Income Tax Act, with everything that follows from it: the gain on the coin given up is realised, and a new holding period of one year begins for the stablecoin received. Moving into a dollar token feels like parking, but it triggers a taxable event. The exemption threshold for private disposals stands at 1,000 euros a year under section 23(3) of that act; exceed it and the entire gain is taxable.

The second point concerns custody. If your stablecoin sits on an exchange, you hold a claim against that exchange, not the token itself. The FSB report describes how unclear the legal position becomes if the issuer becomes insolvent. A second uncertainty is added when a platform stands between you and the issuer. To avoid that, hold the tokens in a wallet whose keys you control yourself, and take on the responsibility for backing them up.

What the report expressly does not do

The note is not a regulation and will not become one. The header of every FSB document states that the activities of the body and the decisions taken in them are not binding and create no rights or obligations. What lies on the table in Bangkok on 15 October is a description of the situation and a list of proposals, each of which is adopted country by country. In Europe that step has already been taken with MiCA; in other jurisdictions it is still pending. For holders that means the gaps the report describes stay open for now, and they stay open precisely where the tokens that dominate the market come from.

Stablecoin oversight: on 15 October it stays at recommendations

The report changes nothing about your holdings this weekend. It does tell you fairly precisely which three questions to put to your own stablecoins.

1. Establish the legal framework of your token. Find out whether the stablecoin you hold comes from an issuer authorised in the EU, and which platform it sits on. The stablecoin overview shows which tokens are regularly offered in Europe.
2. Decide on custody. The longer you hold a stablecoin, the less there is to be said for leaving it on a trading platform. Which devices come into question is set out in the hardware wallet comparison.
3. Document your swaps. Every move into a stablecoin is a tax event with a date of its own. Records kept as you go save a laborious reconstruction in the spring; the tax tools and portfolio trackers take that work off your hands.

The next hard date is not the G20 meeting but the moment when the first large arrangement actually comes under pressure. That this test is still outstanding is the real news out of Basel.
