The Bank for International Settlements released its annual report this week with a direct assessment: stablecoins do not function as money. The central bank cooperative said the assets fail on three counts—singleness, elasticity, and integrity.

Singleness refers to a currency's uniform acceptance across an economy. Stablecoins remain fragmented by blockchain, issuer, and regulatory treatment. A stablecoin on Ethereum carries different risk and liquidity profiles than one on Solana, and neither has the universal acceptance that fiat money commands.

Elasticity measures a currency's ability to expand or contract money supply in response to economic conditions. Central banks adjust rates and reserve requirements to stabilize prices and employment. Stablecoin issuers, by contrast, typically peg supply to collateral or algorithmic rules that do not account for macroeconomic shocks. During stress events, this rigidity can amplify volatility rather than dampen it.

Integrity refers to public confidence in the currency's stability and backing. The BIS flagged the credit and market risks embedded in stablecoin reserves. If an issuer's collateral deteriorates—as with deposits at failing banks or concentrated positions in volatile assets—redemption confidence erodes fast. That structural fragility differs fundamentally from the institutional backing and regulatory oversight of sovereign currency.

Emerging markets bear the brunt

The report warned that stablecoins pose particular risks in emerging economies where they can displace domestic money. When residents lose faith in local currency or face capital controls, stablecoins offer an exit route. The BIS noted that this substitution weakens monetary policy transmission, erodes tax revenue, and can destabilize financial systems already vulnerable to capital flight. Developing-nation central banks lack the foreign reserves and policy tools that larger economies deploy to manage currency competition.

The BIS has been consistent on this point. Previous statements have flagged stablecoins as potential threats to financial stability if adoption accelerates without regulatory guardrails. This report underscores that concern with a focus on jurisdictions least able to absorb the shock.

What comes next

The report does not prescribe specific regulatory action, but the framing aligns with regulatory momentum. The Financial Stability Board, the G20, and national regulators are advancing stablecoin oversight rules. The BIS findings provide institutional weight to arguments that stablecoins need stricter capital, reserve, and redemption standards to function safely.

For issuers, the implications are narrowing headroom. Jurisdictions that have granted operating licenses—El Salvador's use of Bitcoin, for instance, sits outside this frame but reflects similar sovereignty tensions—may face pressure to impose reserve requirements or liquidity buffers that raise operational costs. For users in emerging markets, the report signals that regulators view stablecoin reliance as a systemic risk worth constraining.
