The BIS Speech in Tokyo

Speaking at a Bank of Japan seminar on April 20, 2026, Bank for International Settlements (BIS) General Manager Pablo Hernandez de Cos warned that dollar stablecoins could produce material consequences for financial stability and economic policy if they keep scaling. He named USDt (Tether) and USDC as the central examples. The address framed the current stablecoin arrangement as inadequate for systems that aspire to handle widely used payments.

'Rapid outflows could force sales of those reserves into already strained markets.'

Hernandez de Cos argued that stablecoins behave less like cash and more like exchange-traded funds. Redemption conditions, fees, and thinly capitalised issuers mean holders do not actually hold money. They hold a claim on short-term government debt and bank deposits that must be liquidated under stress. That, he said, creates contagion risks similar to what regulators saw in money market funds during past banking episodes.

What Global Coordination Would Mean

The general manager called for tighter global coordination on stablecoins without specifying mechanisms. In practice, coordination usually means aligned reserve standards, common redemption rules, and shared anti-money-laundering obligations across jurisdictions. He flagged permissionless blockchains and unhosted wallets as channels that sit outside the existing control perimeter.

Europe is moving first. France has pushed the European Union to restrict non-euro stablecoins in everyday payments. The European Central Bank has publicly contrasted euro-denominated stablecoins with tokenised money market funds, signalling a preference for bank-issued instruments. Switzerland launched a franc-denominated stablecoin pilot on April 8, giving regulators a controlled sandbox.

The Incumbent Framing

Central bankers have warned about private money for decades. The specific complaint here is that stablecoin issuers sit outside the central bank lending-of-last-resort backstop while handling instruments that look, to users, like deposits. The BIS is not neutral in this debate. It coordinates central bank policy globally and has championed central bank digital currencies as the public-money alternative to private tokens.

Why It Matters

Fractional reserve banking and unbacked fiat currency caused the conditions that made stablecoins useful in the first place. Dollar stablecoins solve a real problem for people in capital-controlled or inflationary economies, and they do it by holding reserves that are closer to fully backed than any commercial bank holds deposits. The threats the BIS names apply with far more force to the money printers calling the warning. Stablecoin issuers face redemption competition every day. Central banks face it once a generation, if ever. The market is the strictest regulator, and Bitcoin-backed stablecoins remain the natural endpoint for issuers who want reserves that cannot be inflated away by the institution that writes the rules.
