FAQ Section
Q: How does CBDC differ from mobile payment apps?
A: CBDCs represent direct central bank liabilities with legal tender status, unlike commercial bank-issued e-money.
Q: Can CBDCs replace cash completely?
A: Most designs position CBDCs as complementary to physical cash, ensuring continued access for all demographics.
Q: What privacy protections exist for users?
A: Systems typically employ "tiered anonymity" - small transactions remain private while large transfers undergo verification.
Q: How might CBDCs impact traditional banks?
A: Two-tier models preserve bank intermediation roles, though deposit competition may increase funding costs marginally.
Q: When will international CBDC standards emerge?
A: The BIS Innovation Hub targets 2024-2025 for finalized cross-border payment protocols.
