A stablecoin can cross borders. Its reserves may not.

PANTHER JOURNAL #004 · BREAKING ANALYSIS

Imagine a stablecoin holder in one country asking for cash while the assets backing the token sit in another. The token travels instantly. The reserves, banking rails and legal claims may not. In a crisis, that distance could matter more than the word “stable” on the screen.

That is the risk the Financial Stability Board put before G20 finance officials on October 12. Its new cross-border stablecoin note examines how a globally used token could face redemption pressure across jurisdictions, especially when several affiliated issuers share one coin but hold separate reserves. The FSB did not announce a new law or say a stablecoin is failing today. It described a stress scenario that regulators and issuers have yet to prove they can manage.

The token moves. The reserves have an address.

A stablecoin can circulate on public blockchains around the clock. The reserve assets that support its redemption are held through banks, custodians and legal structures in particular places. The FSB says an issuer may not know every holder’s location or where a wave of redemption requests will arrive. Markets for reserve assets and the banking system also run on different hours from crypto trading.

The mismatch is easy to miss in calm markets. Someone selling a token on an exchange can usually find another buyer without going directly to the issuer. But an exchange price near $1 and an enforceable right to redeem $1 from an issuer are different things. When confidence breaks, traders may try to sell immediately while formal redemptions and reserve transfers take longer.

The FSB also identifies a possible counterweight: deep, liquid secondary markets can attract arbitrageurs who buy a discounted token and redeem it, helping restore the peg. That stabilising route depends on redemption actually working and enough capital being willing to take the risk.

The multi-issuer trap

The report focuses on a particularly difficult design. Imagine affiliated companies issuing the same stablecoin in several countries. They share liability for the token, but each holds reserves separately. If holders can redeem with any company in the group, claims could pile up at one issuer while the needed assets remain elsewhere.

Under normal conditions, the companies could rebalance reserves or rely on market trading. Under stress, cross-border transfers, market access, information flows and coordination may slow or fail. The FSB says it can also become unclear which issuer owes which holders and which national insolvency rules apply. This is a risk of that specific structure, not a finding that every stablecoin uses it or is undercollateralised.

The public document names no issuer as the source of a current crisis. CoinDesk’s independent account likewise frames the warning as a test of cross-border crisis planning, not an active run.

Why crypto should care before a depeg

Stablecoins are the cash-like trading and settlement layer of much of crypto. A serious redemption bottleneck could spill into exchange liquidity, DeFi collateral and cross-border payments. The FSB says a run could also transmit pressure to conventional markets if an issuer must sell reserve assets quickly or withdraw bank deposits to fund redemptions. These are possible transmission channels, not a prediction that such a chain reaction will occur.

The board estimated the stablecoin market at around $300 billion in mid-2026, with 99% of value pegged to the US dollar. It said global stablecoins are still used predominantly for entering, exiting and trading crypto assets, while acknowledging potential benefits for payments and financial inclusion. Those benefits and vulnerabilities can coexist.

Readers of Panther’s investigation of the October 10 liquidation cascade have seen a related principle: liquidity available on an ordinary day can vanish when everyone needs an exit at once. Stablecoin redemptions introduce an additional question—where are the assets, and who can claim them when markets are under pressure?

The data gap behind the warning

A blockchain makes transfers visible. It does not reliably reveal the holder’s country, the purpose of a transaction or the location of off-chain reserves. The FSB says authorities rely heavily on private data compilers whose methods can differ, and that geographic attribution of stablecoin flows is often impossible or hard to verify.

That limits both supervision and confident public claims. An on-chain chart can show a token moving; it cannot, by itself, map a legal obligation across affiliated issuers or tell regulators where a redemption queue will form. The FSB proposes better monitoring of reserve locations, redemption flows, secondary-market depth and data gaps, as well as greater cross-border information sharing and planning for distress.

Its October 12 letter to the G20 places this work alongside broader financial stability concerns ahead of the October 15 meeting. The report builds on the FSB’s 2023 recommendations, which call for cooperation, disclosures and recovery planning. FSB recommendations are not automatically binding law; countries implement rules through their own systems.

The Panther takeaway

The next stablecoin stress test will not ask only whether reserves exist. It will ask whether the right reserves can reach the right claimant, in the right jurisdiction, before a round-the-clock market loses patience.

There is no stablecoin run in this report and no new ban. There is a warning about the plumbing behind a promise that looks simple: one token, one dollar. Before trusting that promise, ask who owes the redemption, where the assets sit, and what happens when borders stop being invisible.
