CBDC

A Central Bank Digital Currency is a digital liability of a central bank, denominated in the national unit of account. Unlike bank deposits, which are liabilities of commercial banks, a CBDC is a direct claim on the central bank itself, similar to physical cash but in digital form. Governments and central banks in many countries have explored or piloted CBDCs, motivated by goals such as improving payment infrastructure, expanding financial inclusion, reducing cash handling costs, and maintaining monetary sovereignty as the use of physical cash declines.

CBDCs differ fundamentally from Bitcoin and other cryptocurrency in their architecture and purpose. A CBDC is issued by a central authority that retains full control over supply, issuance, and potentially over individual transactions. Depending on design, CBDCs could allow programmable restrictions on how and where money is spent, automatic expiry dates, or the ability for authorities to freeze or redirect funds. These features distinguish them from physical cash, which is anonymous and unconditional, and from Bitcoin, which is permissionless and censorship-resistant by design.

Proponents argue that CBDCs could modernize payment systems, reduce reliance on private intermediaries, and make monetary policy tools more efficient. Critics raise concerns about financial surveillance, the potential elimination of financial privacy, and the concentration of monetary control in government hands. Some analysts draw a sharp contrast between CBDCs and Bitcoin, observing that they represent opposite approaches: one maximizes state control over money, the other is designed to operate independently of any authority.
