Central bank digital currency


Central bank digital currency is the digital form of fiat money.
The present concept of CBDCs was directly inspired by Bitcoin, but CBDC is different from virtual currency and cryptocurrency, which are not issued by the state and lack the legal tender status declared by the government. Proposed implementations may not even use any sort of distributed ledger.
CBDCs are presently in the hypothetical stage, with some proof-of-concept programmes.

History

Although central banks have directly released e-money previously - such as Finland's Avant stored value e-money card in the 1990s - the present concept of "central bank digital currency" was inspired by Bitcoin and similar blockchain-based cryptocurrencies.
The Bank of England discussed a blockchain-based central bank currency in a September 2015 speech by chief economist Andrew G. Haldane, on possible ways to implement negative interest rates. A March 2016 speech by Ben Broadbent, the bank's deputy governor of monetary policy, appears to be the first use of the phrase "central bank digital currency", and notes direct inspiration by Bitcoin.
The central bank of Sweden mooted an "e-krona" in November 2016, and started testing an e-krona proof of concept in 2020.
In November 2017, the central bank of Uruguay announced to begin a test to issue digital Uruguayan pesos.
In March 2019, the Eastern Caribbean Central Bank announced it would engage in a pilot CBDC project with Barbados based FinTech company Bitt.
In the Eurozone, the Bank of Spain's former governor Miguel Angel Fernandez Ordoñez has called for the introduction of a digital euro, but the European Central Bank has so far denied such possibility. Nevertheless, in December 2019, the ECB stated that "The ECB will also continue to assess the costs and benefits of issuing a central bank digital currency that could ensure that the general public will remain able to use central bank money even if the use of physical cash eventually declines".

Implementation

A central bank digital currency would likely be implemented using a database run by the central bank, government, or approved private-sector entities.The database would keep a record of the amount of money held by every entity, such as people and corporations.
In contrast to cryptocurrencies, a central bank digital currency would be centrally controlled, and so a blockchain or other distributed ledger would not be required or useful - even as they were the original inspiration for the concept.

Characteristics

CBDC is a high security digital instrument; like paper bank notes, it is a means of payment, a unit of account, and a store of value. And like paper currency, each unit is uniquely identifiable to prevent counterfeit.
Digital fiat currency is part of the base money supply, together with other forms of the currency. As such, DFC is a liability of the central bank just as physical currency is. It's a digital bearer instrument that can be stored, transferred and transmitted by all kinds of digital payment systems and services. The validity of the digital fiat currency is independent of the digital payment systems storing and transferring the digital fiat currency.
Proposals for CBDC implementation often involve the provision of universal bank accounts at the central banks for all citizens.

Benefits and impacts

Digital fiat currency is currently being studied and tested by governments and central banks in order to realize the many positive implications it contributes to financial inclusion, economic growth, technology innovation and increased transaction efficiencies. Here is a list of potential advantages:
A general concern is that the introduction of a CBDC would precipitate potential bank runs and thus make banks' funding position weaker. However, the Bank of England found that if the introduction of CBDC follows a set of core principles the risk of a system-wide run from bank deposits to CBDC is addressed.
