The Bank for International Settlements (BIS) used its Annual Economic Report 2026 to issue a stark warning that current stablecoin designs fall dangerously short of sound money, potentially fragmenting the global financial system and threatening emerging economies. Released on June 28, the report judges dollar‑pegged tokens against four foundational monetary properties—singleness, elasticity, interoperability, and integrity—and finds them lacking on every count.
Stablecoins behave more like exchange‑traded fund shares than reliable means of payment, the report argues. Prices deviate from pegs in secondary markets, and redemptions involve friction and delays. With a total market value of roughly $320 billion—over 99% of it in US dollar‑backed tokens, overwhelmingly split between Tether’s USDT and Circle’s USDC—the sector remains tiny next to the banking system, but the BIS models what would happen if it grew to $1 trillion, $2 trillion or even $3 trillion. In each scenario, the net effect on economic output turns slightly negative as higher bank funding costs and weaker lending offset any fiscal gains.
The report also highlights stablecoins as a channel for illicit finance because they circulate on permissionless blockchains where pseudonymity and self‑custodied wallets weaken anti‑money‑laundering controls. For developing nations, the BIS warns of “stablecoin dollarization,” where households ditch volatile local currencies for dollar‑pegged tokens, eroding monetary sovereignty, pulling deposits from domestic banks, and exposing economies to sudden cross‑border capital flows.
Public blockchains such as Bitcoin and Ethereum come under fire for their inability to scale to large‑scale financial infrastructure and for lacking clear governance and accountability. Instead of a ban, the BIS pushes a “unified ledger” model that would bring tokenized central bank reserves, tokenized commercial bank money, and other regulated private money onto a single programmable platform. It points to Project Agora, a cross‑border payments prototype involving eight central banks, the BIS, and more than 40 private institutions, as evidence the concept is viable.
