A dollar stablecoin can change hands across borders and blockchains at any hour. Its issuer may hold reserve assets in one jurisdiction while users trade the token in several others. An October 12 Financial Stability Board note says the resulting obligations and flows are difficult for any single authority to observe. The missing information becomes consequential when a token trades below its peg and users seek redemption from whichever entity can pay.
Summary
- Stablecoins had about $300 billion in market value in mid 2026, according to the Financial Stability Board.
- Dollar pegged tokens represented 99% of that market by value in the board’s mid 2026 estimate.
- The FSB says an issuer may not know the location of holders or where redemption demand will arise.
- Separate issuers of 1 token can hold distinct reserves while sharing liability across borders.
- The board proposes better monitoring metrics and data coordination, not a binding new licensing regime.
The Financial Stability Board’s nine page G20 note is more specific than a general warning about stablecoins. It traces three distinct problems: internationally mobile tokens can produce localized redemption pressure, linked issuers may hold reserves in different places, and public blockchain data often cannot reliably identify the country or purpose of a transfer. Its observations are a work program for authorities, not new law imposed on issuers.
The arithmetic in the report shows why the issue is not limited to a single company’s balance sheet. With roughly $300 billion of stablecoins outstanding in mid 2026 and 99% pegged to the dollar, a simple multiplication puts the dollar pegged share around $297 billion. The estimates are dated and rounded. They say nothing about the fraction redeemable on a given day or the location of the holders who might seek cash.
A global token can have a local legal claim
The FSB defines a global stablecoin by its current or potential reach across jurisdictions and its potential systemic importance in one or more of them. Its October note says the issuer’s redemption undertaking and reserve assets can be anchored in specific legal systems even as the token circulates globally. A holder’s wallet address does not announce which court would hear a dispute or which entity owes that holder money.
Bank routes for USDC minting and redemption show how institutional conversion can rely on a regulated intermediary. A token transferred from an exchange in one country to a self controlled wallet in another may settle onchain within minutes. The reserves that back it sit in bank deposits, government securities or other assets subject to institutions’ operating hours and legal rules. The bridge between a 24 hour token market and timed cash settlement is central to the report. If secondary market sellers become impatient while direct redemption is slower, the market price can diverge from the promised peg.
An issuer may not know who holds its liabilities, where holders are domiciled or where redemption requests will arrive, the FSB writes. An exchange may know some customers under its identification procedures without knowing the final location of tokens withdrawn to outside wallets. A blockchain can show addresses and amounts, but residence and beneficial ownership do not appear on an ordinary transfer record. No single view automatically joins these facts.
There is an important counterweight. A deep secondary market can bring in arbitrageurs who buy a discounted token and redeem it, helping restore the peg. The FSB explicitly recognizes that possibility. The outcome depends on access to redemption, bank hours, confidence in reserves and the ability of intermediaries to move money. A temporary discount is not proof of insolvency, while a $1 quote on one venue is not proof that every holder can redeem at par.
Multi issuer designs change where pressure lands
The report pays special attention to a configuration in which affiliated issuers jointly share liability for one global stablecoin but keep separate reserves. Holders may be allowed to redeem with any affiliate regardless of where their tokens were issued. In normal conditions, that can make a token easier to use internationally. Under stress, demand might cluster at one affiliate even though the group’s reserves are distributed elsewhere.
A simplified example makes the issue visible without describing an existing issuer. Suppose two affiliates each issue $1 billion of tokens and each holds $1 billion in local reserves. If holders demand $1.5 billion of redemption from affiliate A and $0.5 billion from B, the group has $2 billion against $2 billion of requests, yet A faces a $500 million local shortfall until reserves or liquidity move across borders. Whether the affiliate can get that liquidity depends on legal access, settlement hours, asset quality and coordination. Group wide backing alone does not eliminate a time and location mismatch.
The FSB says secondary market trades and cross border reserve rebalancing could realign the demands. It also says those mechanisms may fail under stress. If nobody can establish which affiliate’s liabilities correspond to tokens held through intermediaries, the legal picture becomes harder in insolvency. A broad assertion that every token has the same redemption right in every jurisdiction would require the actual contractual terms, which the FSB does not supply for every arrangement.
The paper does not claim all stablecoins use multi issuer structures. A single issuer with transparent reserve management faces different questions. The multi issuer passage identifies a specific vulnerability that deserves its own monitoring: the geography of reserve assets versus the geography of redemption demand. A single aggregate reserve ratio cannot reveal that distribution.
A run could pass through banks and markets
Stablecoins are used primarily within crypto markets at present, the FSB says, as liquidity for entering, exiting and trading assets. Some emerging economies use them as stores of value, and broader payment use could develop. The channel through which distress spreads depends on that use. A trading venue could lose a settlement asset; a merchant payment network could face delays; a reserve manager could have to liquidate securities to meet cash calls.
The report lists potential spillovers through reserve asset sales, withdrawals of bank deposits to fund redemptions, dependence on stablecoins for real economy payment or settlement, and foreign exchange markets used for cross border transactions. It does not say such a chain of events has already happened at the scale of the whole system. The point is to monitor links before a problem at one participant becomes a problem for others.
A redemption wave need not start with deficient reserves. Rumors, platform restrictions or a temporary inability to move funds across markets could cause holders to sell below par. Conversely, high quality liquid reserves and clear redemption rights can reduce the chance of a prolonged gap. Quantity and quality of backing assets, as well as oversight, are central to resilience in the FSB’s account.
For smaller economies, scale has a different meaning. A stablecoin that is modest beside the global dollar market could matter greatly within a local banking and payments system. The ECB’s reserve concern highlights how redemption stress could reach banks. The FSB points to currency substitution, bank disintermediation and difficulty managing capital flows in emerging market and developing economies. Its warning is conditional on adoption and local circumstances, not a claim that every cross border transfer is destabilizing.
The public ledger cannot answer the geography question
Blockchains generate abundant records. A transfer record generally reports a token contract, source address, destination address, amount and time. It does not reliably say whether the movement represents a remittance, exchange collateral, a trader moving funds between own wallets or a transfer between two people in different countries. A centralized exchange may also net many customer trades internally without an onchain transaction for each trade.
U.S. issuer rules address reserves and redemption but do not produce a universal map of overseas holders. The FSB divides data problems into two categories. Structural gaps arise from pseudonymity and smart contract architecture, so better scraping alone may not reveal the person or location behind every address. More tractable gaps include information that exists but is not shared with authorities, and inconsistent methods and formats used by data companies. The two categories require different remedies. Publishing a richer onchain dashboard cannot compel an offchain custodian to disclose a customer geography breakdown.
Private data compilers currently provide much of the information authorities use, according to the report. Their clustering rules and filtering methods may differ. One provider might count transfers between wallets controlled by the same exchange as volume; another might remove them. Neither number is necessarily fraudulent. Without the methods, a regulator comparing the two cannot know whether a divergence reflects changing activity or changing measurement.
A basic reporting question illustrates the problem. “How much stablecoin crossed the border this week?” requires a reliable country label at both ends, an account of internal exchange transfers, a way to exclude self transfers and a consistent rule for multi chain bridges. Onchain data alone does not produce those inputs. A precise looking number from a proprietary model can still have a wide uncertainty range.
The paper acknowledges improving data availability. Shared formats, disclosed heuristics, combining sources and reporting requirements could improve estimates. The board does not suggest that every transfer must become publicly identifiable for monitoring to work. Authorities may need aggregate information from issuers and regulated intermediaries, with protections and coordination for information collected in different countries.
Who sees the reserves, and who sees the holders?
An issuer or auditor can inspect reserve accounts and obligations recorded within the issuer’s system. A custodian bank sees the assets it holds, subject to its legal and reporting obligations. An exchange sees customer balances and transfers within its platform. A chain analyst sees token movements between addresses, often without the identity behind them. A national supervisor may receive reporting from entities within its remit, while meaningful activity happens in another jurisdiction.
None of those partial views is inherently useless. The problem is their mismatch. A reserve attestation can confirm assets at a reporting time without mapping where future redemption pressure will originate. Exchange customer records can identify a subset of holders without showing all wallet based circulation. Onchain supply figures can identify token contracts while missing a claim that exists in another ledger or legal arrangement.
The FSB suggests monitoring the depth, liquidity and structure of secondary markets, along with the geographic distribution of holdings, redemptions and reserve assets. Geography is especially relevant for multi issuer structures. It also calls for analytical expertise, information sharing and possible industry practices for collecting and compiling onchain and offchain data. The proposed metrics are a direction of travel, not a completed universal template with thresholds that would trigger intervention.
The FSB chair’s accompanying letter frames the work for the October 15 G20 finance ministers and central bank governors meeting. It asks for continued implementation of the board’s 2023 recommendations and cross border cooperation. A G20 discussion may shape later domestic measures, but the October note itself cannot license, prohibit or rescue an issuer.
Existing rules remain uneven across borders
Circle’s October policy submission argues for changes to EU treatment of cross border issuance. The FSB’s 2025 peer review of stablecoin recommendations found gaps and inconsistencies in national implementation. The latest note says treatment of foreign issued stablecoins remains uncertain or undefined in many jurisdictions. A company may issue in one country, distribute through affiliates in others and be traded through platforms subject to different licensing rules.
The solution is not a single global regulator, which the FSB does not propose. Its own mandate is to coordinate national authorities and standard setters; its decisions are nonbinding. Information sharing agreements, comparable reports and crisis plans could let existing authorities form a less fragmented picture. Whether domestic law permits each agency to request or exchange specific data remains a question for that jurisdiction.
A bank pilot on Stellar illustrates interest in cross border settlement. The industry case for global tokens also matters. Cross border payments can be slow and expensive, and tokens available at all hours can make transfers easier. The FSB acknowledges possible faster and cheaper transactions and financial inclusion. Some benefits may come from distributed ledger infrastructure itself, not uniquely from a privately issued stablecoin. A policy analysis that counts only risk would miss why users and businesses adopt the instruments.
The unresolved issue is who can act on information once it arrives. A regulator who observes an exchange discount might lack authority over an issuer abroad. An issuer might control redemption but not the marketplace selling the token. A bank might hold reserves but have no relationship with the wallet holder. Coordinated data is necessary for oversight; it is not sufficient unless roles in stress and insolvency are set before stress occurs.
The report’s limit is part of its finding
The board calls its data work an assessment of important sources and limitations, not a comprehensive inventory of everything supervisors need. It does not identify an imminent run, assign a loss probability or set a new capital requirement. The roughly $300 billion and 99% figures describe mid 2026, not a live October 13 dashboard. Treating a monitoring note as a forecast would overstate its claim.
A useful follow up will track whether authorities can obtain comparable data on redemption queues, reserve locations and cross border secondary market liquidity. It will ask which institution can use that information during a crisis and whether legal claims travel with tokens across affiliated issuers. The FSB has named the information missing from its view. Domestic supervisors and issuers now have to say what they can provide and what remains structurally unobservable.
What to watch
- October 15 G20 meeting: Check whether finance ministers endorse further work or set a timetable for cross border stablecoin monitoring.
- FSB metrics: Look for a published, comparable set of measures covering secondary liquidity and the location of reserves and redemptions.
- Multi issuer terms: Inspect whether affiliated issuers specify which entity owes a holder cash and where claims can be enforced.
- Data disclosure: Track whether issuers and regulated intermediaries report geography and redemption flows in consistent formats.
- Crisis procedures: See whether national authorities publish coordination arrangements for distress at a global stablecoin issuer.
FAQ
What did the FSB publish on October 12, 2026?
It published a nine page note for the G20 on cross border vulnerabilities and the limits of available stablecoin monitoring data. The note does not impose binding new rules.
How large was the stablecoin market in the report?
The FSB estimated around $300 billion in mid 2026, essentially unchanged from a year earlier. It said 99% by value was pegged to the U.S. dollar.
Why can an issuer not identify all token holders?
Tokens circulate across secondary markets and pseudonymous wallets. An issuer may know direct redemption customers without knowing each person holding tokens acquired elsewhere.
What is a multi issuer stablecoin arrangement?
In the FSB’s example, affiliated issuers share liability for one token but keep separate reserves. Redemption demand can concentrate at an affiliate holding less immediately accessible cash.
Does an onchain transfer show a cross border payment?
It shows addresses and a token movement. It does not reliably establish the residence of both owners or whether the transaction was a payment, self transfer or exchange activity.
Can a secondary market help a stablecoin hold its peg?
Yes. The FSB says liquid trading can support arbitrage toward par. Market access, reserve liquidity and direct redemption rights determine how effective that route is during stress.
Is the FSB creating a single global stablecoin regulator?
No. The FSB coordinates national authorities and issues nonbinding policy work. Domestic laws and supervisors govern actual licensing and enforcement.
What data does the FSB want authorities to monitor?
It identifies secondary market depth and liquidity and the geography of holdings, redemptions and reserves, particularly in multi issuer structures. This is educational analysis, not investment advice.
