Introduction to CBDCs
Central Bank Digital Currencies (CBDCs) have gained significant global attention as a modern complement to physical cash. According to the Bank for International Settlements (BIS), 86% of central banks worldwide are actively researching CBDCs, with 14% already conducting pilot tests. These digital currencies represent:
- Official liabilities of central banks
- Advanced payment instruments with regulatory applications
- Potential tools for monetary policy implementation
Hong Kong began exploring CBDC feasibility in 2017 and continues to test cross-border trade applications while researching a retail digital Hong Kong dollar (e-HKD).
Understanding CBDCs
Core Characteristics
- Digital equivalents of physical banknotes
- Direct central bank liabilities (unlike cryptocurrencies)
Two primary types:
- Retail CBDCs: For public/enterprise use
- Wholesale CBDCs: For interbank settlements
Technological Infrastructure
CBDC systems require digital ledgers to:
- Prevent "double-spending"
- Track currency supply
Support either:
- Centralized databases or
- Distributed Ledger Technology (DLT)
