What is Central Bank Digital Currency (CBDC)?
- A Central Bank Digital Currency(CBDC) is the digital form of a central bank’s fiat currency that is also a claim on the central bank.
- Instead of printing money, the central bank issues electronic coins backed by the full faith and credit of the government.
- The Bank of England have described a CBDC as electronic Central Bank’s money that:
- Potentially has much greater functionality for retail transactions than cash
- Has a separate operational structure to other forms of Central Bank money, allowing it to potentially serve a different core purpose, and
- Can be interest bearing, under realistic assumptions paying a rate that would be different to the rate on reserves
- Can be accessed more broadly than reserves under bank

Why is the government not in favour of crypto currency?
Generally, cryptocurrencies generate a negative sentiment amongst government, with the following key arguments:
- Most of the countries deny them the definition of currency and argues that they do not meet the functions of money.
- They are a highly volatile, speculative, medium that distorts the market, pulling away investment from the real economy and innovation into the bubble.
- They are vulnerable to crime and expose consumers and investors to high risks of loss.
- Despite the decentralisation claims of the underlying technology, they are prone to 51% attack.
- The technology is not scalable, is inefficient due to its slow speed of transactions, and has a high environmental impact due to miners’ energy use for computing power.
What are the advantages of CBDC?
- Practically costless medium of exchange: If CBDC were account-based, the accounts (like bank accounts) could be held directly at the central bank itself or made available via public-private partnerships with commercial banks, hence the transaction will reflect in the books of Central Bank which would eliminate the intermediaries and hence the cost of transaction will reduce drastically
- Secure storage of value useful for investment: Interest-bearing CBDC could have a rate of return in line with risk-free assets such as short-term government securities. The CBDC interest rate would serve as the main tool to attract investment
- Gradual obsolescence of paper currency: CBDC can be made widely available to the public, which will improve our cash to GDP ratio and boost digital payments and reduce tax evasion.
- True price stability: An effective monetary policy is possible if the real value of CBDC would remain stable over time. Such framework would encourage the systematic and transparent conduct and better transmission of monetary policy.
What are the concerns surrounding CBDC?
- Privacy issues: Central banks may have increased control over money issuance and greater insight into how the people spend their money, potentially depriving citizens of their privacy.
- Disintermediation of commercial banks: If citizens move their money from bank accounts into CBDC, this could start a vicious cycle as banks raise deposit rates to attract more money. In turn, this means less bank credit extended at higher interest rates
- Reputational risk for a central bank: Since CBDC involves a huge infrastructure, and if any citizen suffers glitches, cyber-attacks or human error, it could reflect poorly on the central bank’s reputation.
- Bank runs to CBDC: An oft-cited risk to introducing CBDC is the risk of a bank run as depositors would easily be able to transfer bank deposits to the Central Bank this would create a concept of flight of capital within banking system as well.
Conclusion
With a changing payments landscape, Central Banks have recognised that they too need to develop to aid this transition and incorporate new technology. If a private e-money issuer was to control the majority of payments in a country and there was a clear move away from the fiat currency, the CB would lose its ability to implement monetary policy. Against this backdrop, Central Banks are trying to understand the financial and economic impact of introducing their own digital currency, and we may expect our own CBDC in near future tweaked according to Indian financial system.
