CBDC vs UPI: What is the Difference?

Understanding CBDC

Definition and Concept

Central Bank Digital Currency (CBDC) is a digital form of central bank money that is designed to serve as legal tender. Unlike cryptocurrencies, which are typically decentralized and often volatile, CBDCs are issued and regulated by a country’s central bank, ensuring stability and trust. They represent a direct claim on the central bank, similar to physical cash, but in a digital format.

Types of CBDC

CBDCs can be broadly categorized into two types:

• Retail CBDC: Intended for use by the general public, retail CBDCs are designed to facilitate everyday transactions. They can be used for person-to-person payments, retail purchases, and other consumer-level transactions.
• Wholesale CBDC: Targeted at financial institutions, wholesale CBDCs are used for large-scale interbank transactions, improving the efficiency and security of the financial system’s infrastructure.

Implementation and Technology

The implementation of CBDCs involves sophisticated technology, often leveraging distributed ledger technology (DLT) or blockchain. However, not all CBDCs use blockchain; some may utilize conventional centralized databases to achieve the desired functionality.

• Security and Fraud Reduction: As a sovereign-backed currency, CBDCs can enhance the security of payments and reduce fraud.
• Monetary Policy Implementation: CBDCs can provide central banks with new tools for monetary policy, such as direct distribution of stimulus funds.

Challenges and Concerns

Despite their potential, CBDCs face several challenges:

• Privacy: Balancing the need for privacy with anti-money laundering (AML) and counter-terrorism financing (CTF) regulations is complex.
• Cybersecurity: Ensuring robust cybersecurity to protect against hacking and digital theft is critical.
• Economic Disruption: The introduction of CBDCs could disrupt existing financial institutions and payment systems.
