The Banque de France (BDF) and the Hong Kong Monetary Authority (HKMA) are joining forces to explore interoperability between their central bank digital currency (CBDC) infrastructures. The collaboration aims to improve cross-border transaction settlement efficiency. The HKMA will use its Project Ensemble sandbox for research, while the BDF will utilize its DL3S platform. Project Ensemble, launched in March, aims to study asset tokenization and create a CBDC to support it. The HKMA and BDF are also part of other projects, including the European Central Bank's distributed ledger technology testing.
