What is Central Bank Digital Currency (CBDC) & how it works

A Central Bank Digital Currency (CBDC) is a digital form of a country's fiat currency, issued and controlled by its central bank. Unlike cryptocurrencies like Bitcoin, CBDCs are fully regulated, centralized, and backed by the government.

CBDCs aim to modernize payments, reduce cash dependency, and improve financial inclusion while maintaining government control over money supply and policy.

How CBDCs work

• Issued by a central bank – Unlike decentralized cryptocurrencies, CBDCs are controlled by the central bank.
• Digital representation of fiat – A CBDC is just a digital version of traditional money, such as digital dollars, euros, or yuan.
• Direct or indirect use –
  • Retail CBDC: Used directly by the public for payments and savings.
  • Wholesale CBDC: Used only by banks and financial institutions for interbank settlements.
• Blockchain or centralized database – Some CBDCs use blockchain-like technology, while others rely on traditional banking infrastructure.

Key Differences: CBDC vs. Cryptocurrency

Benefits of CBDCs

• Faster & cheaper transactions – Reduces settlement time for payments.
• Financial inclusion – Provides banking services to unbanked populations.
• Reduced cash dependence – Lowers costs of printing and managing physical money.
• More efficient monetary policy – Allows governments to distribute stimulus funds directly.
• Enhanced security – Less risk of counterfeit money or fraud.

Concerns & risks of CBDCs

• Privacy issues – Governments can track and control transactions.
• Potential for financial surveillance – Could limit financial freedom if misused.
• Risk to commercial banks – Direct access to central bank money could disrupt traditional banking.
• Cybersecurity risks – A centralized system could be vulnerable to hacking.
