Central Bank Digital Currency (CBDC)

A CBDC is a central bank's own digital money, carrying the same legal status as banknotes and coins but existing only as an electronic record. Unlike commercial bank deposits, a CBDC is a direct liability of the central bank itself, and unlike Bitcoin it is fully centralized: the issuing authority controls supply, settlement rules and, in many designs, who can hold it.

Central banks explore CBDCs to modernize payment infrastructure, preserve public access to central bank money as cash use declines, and counter the private issuance of dollar-pegged stablecoins. Retail CBDCs target everyday consumer payments, while wholesale CBDCs are restricted to banks settling large transactions between themselves; some, like China's e-CNY, blur the line by adding features such as bank-paid interest on holdings.

Adoption remains uneven. As of 2026, well over a hundred countries are researching or piloting a CBDC, but only the Bahamas' Sand Dollar, Jamaica's JAM-DEX and Nigeria's eNaira have fully launched at retail scale. China's e-CNY is the largest pilot by transaction volume, active across dozens of cities, and cross-border wholesale projects such as mBridge are scaling quickly. The European Central Bank continues preparing a digital euro pending EU legislation, while the United States has legislatively barred the Federal Reserve from issuing a retail CBDC, steering digital-dollar demand toward regulated stablecoins instead.

Privacy, financial stability, and the risk of central banks disintermediating commercial banks remain the most debated concerns around any CBDC rollout.
