A global, unified currency where “all banks worldwide” use the same system does not exist and is not an active policy proposal at the Federal Reserve, IMF, or Bank for International Settlements (BIS). The Federal Reserve has published research on a potential U.S. central bank digital currency (CBDC) but explicitly stated it would only proceed with clear support from the executive branch and Congress — no U.S. CBDC has been authorized or implemented as of 2026.

Individual countries (China’s e-CNY pilot, for example) have tested domestic CBDCs, but these are separate national systems, not a unified global currency replacing existing banking. If you’re concerned about CBDC policy, the Federal Reserve’s own public reports at federalreserve.gov are the primary source — not a video’s framing of an unimplemented global system.
