In recent years, central banks have been actively exploring cryptocurrency and its technological advantages for issuing their own national digital currencies. However, as with any technological innovation, there are both pros and cons.
Pros: - Distribution of currency. It is safer and cheaper to transport than cash. Provides public access to legal electronic means of payment.
- Payments. Conventional digital fiat and centralized cryptocurrencies have the following advantages: faster settlement rates, potentially lower fees, and a single point of failure. More anonymity than with card payments.
A cryptocurrency based on blockchain technology has a similar set of advantages. It improves settlement timeframe, operational resilience, and cyber resilience. All transactions are recorded in one ledger. Cheaper international payments. - Interest-bearing monetary policy. Provides direct transfer of monetary policy data to households and companies. Competes with private cryptocurrencies to improve monetary policy. Efficient in case of widespread use of private cryptocurrencies.
Cons:- Distribution of currency. Significant investment is required for release. Transactions over a certain size must comply with AML/CFT legislation. Consumers can accidentally lose large amounts of regular tokens.
- Digital currency or cryptocurrency. Reduces the demand and supply of cash, which can reduce the availability of cash during a power outage.
- Payments. Сryptocurrency, like blockchain, has slower payment authorization, as well as an inefficient use of electricity and higher transaction fees at a low cost of payments. Doesn't scale and has probabilistic finality. Cross-border transactions in any digital currency will require an exchange.
- Interest-free monetary policy. Creates a zero bottom line for monetary policy.
- Reduction of financial stability and resilience of banks to economic downturns and stimulation of profit-seeking behavior. The increasing dependence of commercial banks on wholesale financing from abroad, susceptibility to a decrease in turnover in foreign markets. Increase the likelihood and severity of mass withdrawals from a bank during periods of system-wide instability.
Summary. Policymakers should investigate the implications of central bank digital currencies for monetary policy and the financial system, examining how a central bank digital currency can be issued to the public, while mitigating possible disadvantages.
