Stablecoins vs CBDCs: How the U.S., EU and China differ

In July 2026, the 21st Century ROAD to Housing Act became law and prohibits the Federal Reserve from issuing a retail central bank digital currency until December 31, 2030. That legislation followed the GENIUS Act of July 2025, which created a regulatory framework for payment stablecoins, requiring full reserves and banning interest payments to holders of U.S. payment stablecoins.

Stablecoins are digital tokens issued by private firms such as Tether, Circle and Paxos. Issuers maintain a peg by holding reserves of cash, U.S. Treasury bills and short-term repo. These tokens run on public blockchains including Ethereum, Tron and Solana, and can be sent and received by anyone with a compatible wallet without opening an account with the issuer. The market has grown to more than $300 billion in supply and handles over $1 trillion in monthly volume across trading, remittances and business payments.

A central bank digital currency is digital money issued directly by a central bank and is a direct liability of the state, equivalent in legal status to cash. CBDCs come in retail forms for public payments and wholesale forms for interbank settlement. By mid-2026 three retail CBDCs were fully launched: the Bahamian Sand Dollar, Jamaica’s JAM-DEX and Nigeria’s eNaira. China’s e‑CNY operates at a larger scale, has been used in cross‑border pilots and has recorded over 16 trillion yuan in cumulative transactions. China began paying interest on e‑CNY wallet balances on January 1, 2026. The European Central Bank is preparing a digital euro, with legislation moving through 2026, a pilot planned for 2027 and a target for broader rollout around 2029.

Stablecoins and CBDCs differ on issuer risk and legal status. Holders of a stablecoin hold a claim on a private issuer and are exposed to that issuer’s solvency and reserve quality. A CBDC balance is a claim on the central bank and carries sovereign credit risk rather than private issuer risk. Stablecoins use open blockchain rails that allow fast settlement, composability and cross‑border reach. CBDCs typically run on permissioned or state‑controlled infrastructure that requires approved intermediaries and can provide guaranteed settlement and offline payment functions.

Privacy and control vary by design. Stablecoin transactions are visible on public ledgers but remain pseudonymous until linked to an identity through an exchange or compliance process; issuers can freeze addresses in response to legal requests. CBDCs are designed with government visibility into transactions and may include the ability to limit holdings or freeze balances; concerns about state surveillance were cited by lawmakers during U.S. debates on a Fed retail CBDC. The digital euro’s designers have proposed cash‑like privacy protections and holding caps.

Regulatory approaches differ. U.S. law now channels the digital‑dollar role to regulated private stablecoins under reserve and audit requirements. European rules and the digital euro emphasize payment sovereignty and limits on non‑compliant tokens for retail users. China’s e‑CNY operates under central bank control and has been integrated into pilots for cross‑border payment networks.

As of mid‑2026, stablecoins are widely used on open blockchain rails and for cross‑border transfers, while several central banks are developing or operating CBDCs for domestic retail payments. The U.S. restriction on a Fed retail CBDC remains in effect through December 31, 2030.
