A central bank digital currency (CBDC; also called digital fiat currency [1] or digital base money [2] ) is a digital currency issued by a central bank, [3] rather than by a commercial bank. It is also a liability of the central bank, unless it is dividend-paying, then it is an ownership stake in the central bank, and is a new form of legal tender, unlike regular retail CBDC which is denominated in the sovereign currency, [4] as is the case with physical banknotes, coin and existing reserves.
The two primary categories of CBDCs are retail and wholesale. [5] Retail CBDCs are designed for households and businesses to make payments for everyday transactions, whereas wholesale CBDCs are designed for financial institutions and operate similarly to central bank reserves. [5]
Retail CBDCs can be distributed through various models. In the intermediated model, the central bank issues the CBDC and manages core infrastructures, while financial intermediaries offer customer services. The ECB and the Federal Reserve have proposed intermediated CBDCs. [6] [7] Alternatively, the central bank could either provide the full service or delegate responsibilities further. [4]
While CBDCs may share some properties with virtual currency and cryptocurrency, such as programmability, [8] they differ in that a CBDC is issued by a state. [9] [10] [11] [12] However, most retail CBDC implementations will likely not use any sort of distributed ledger such as a blockchain. [13] [14] [15]
As of 2023, over 120 different jurisdictions, including major economies like the ECB, UK, and the US, were evaluating national digital currencies. [16] As it currently stands, 9 countries and the 8 islands making up the Eastern Caribbean Currency Union have launched CBDCs; 38 countries and Hong Kong have CBDC pilot programmes; and 67 countries and 2 currency unions are researching CBDCs. [16] In the United States, some states have introduced legislation [17] [18] to ban state payments using CBDCs with Florida being the first state to pass such a law citing privacy concerns. [19]
CBDCs have faced a plethora of criticisms, including concerns about privacy and the potential for them to be used as a "tool for coercion and control". [20] Their implementation could also have a displacement effect on the private sector, affecting bank balance sheets and private payment methods, necessitating carefully calibrated policies. [21]
Although the term "CBDC" did not become widely used until after 2019, central banks have researched and launched digital currency projects for decades. For example, Finland's central bank issued the Avant stored value e-money card in the 1990s. [22] In 2014, the Chinese central bank began researching the idea of issuing a CBDC. [23] Elsewhere, the Ecuadorian central bank operated a mobile payment system from 2014 to 2018. [24] In 2021, Australia's central bank conducted a proof of concept for a wholesale CBDC using Ethereum to tokenize syndicated loans, aiming to automate and secure high-value transactions in the banking sector. [25]
A central bank digital currency would likely be implemented using a database run by the central bank, government, or approved private-sector entities. [13] [14] [15] The database would keep a record (with appropriate privacy and cryptographic protections) of the amount of money held by every entity, such as people and corporations. [13]
In contrast to cryptocurrency, a central bank digital currency would be centrally controlled (even if it was on a distributed database), and so a blockchain or other distributed ledger would likely not be required or useful - even as they were the original inspiration for the concept. [13] [14] [15]
By March 2024, the central banks of 134 countries accounting for 98% of the world's GDP were said to be in various stages of evaluating the launch of a national digital currency. [26] These included the ECB, the UK, and the US. [27] [28] China's digital RMB was the first digital currency to be issued by a major economy. [29] [30] Six central banks have launched a CBDC: the Central Bank of The Bahamas (Sand Dollar), the Eastern Caribbean Central Bank (DCash), the Central Bank of Nigeria (e-Naira), the Bank of Jamaica (JamDex), People's Bank of China (Digital renminbi), the Reserve Bank of India (Digital Rupee), and Bank of Russia (Digital Ruble). [31] The Central Bank of Brazil has been rolling out tests of a digital Brazilian currency (Drex) since March 2023. [32] The ECB/Eurozone decided in October 2023 to move forward to the preparation phase for the potential issuance of a digital euro after a two-year study phase. [33]
Some states have also issued, or have considered issuing, cryptocurrencies: these include Venezuela (Petro) and the Marshall Islands (Sovereign). These cryptocurrencies are often considered with the intent of increasing a state's independence from global financial systems, such as by reducing dependence on a foreign currency or by evading international sanctions. [34] [35]
Contrasting attitudes towards digital currencies were demonstrated by developments in the UK and Switzerland in February 2023. The UK Treasury and the Bank of England said a state-backed digital pound was likely to be launched some time after 2025. Two weeks later, a Swiss lobby group triggered a national vote on maintaining a "sufficient quantity" of cash in circulation over fears that electronic payments make it easier for the state to monitor its citizens' actions. [36] In a comment on the British government's plans, the BBC's Faisal Islam said the issue was about access to the data attached to every spending transaction, and whether people might choose to trust a global company more than the state: "The eye here is on maintaining UK monetary sovereignty against upheaval from the likes of Big Tech." [37]
A major problem with central bank digital currencies is deciding whether the currency should be easily traceable. If it's traceable, the government has more control than it currently does. Additionally, there's a technical aspect to consider: whether CBDCs should be based on tokens or accounts and how much anonymity users should have. [38]
A CBDC is a digital counterpart to fiat money, issued by central banks, unless it is dividend-paying, then it is an ownership stake and a new form of legal tender. [39] Like paper banknotes, it is a means of payment, a unit of account, and a store of value. [40] And like paper currency, each unit is uniquely identifiable to prevent counterfeiting. [41] CBDC will have implications for commercial banks, probably in the field of lowering banks' commissions, no big customer data-selling ability, accumulating the deposits and deposit policies and credit policies due to higher funding costs for banks. [42]
Digital fiat currency is part of the base money supply, [43] together with other forms of the currency. As such, DFC is a liability of the central bank just as physical currency is. [44] It is 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. [45]
Proposals for CBDC implementation often involve the provision of universal bank accounts at the central banks for all citizens. [46] [47]
Governments and central banks are studying CBDCs and their implications for financial inclusion, economic growth, technology innovation, and the efficiency of bank transactions. [48] [49] Potential advantages include:
Despite having potential advantages, CBDCs remain a controversial topic, and there are risks associated with their implementation.
A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
A central bank, reserve bank, national bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Many central banks also have supervisory or regulatory powers to ensure the stability of commercial banks in their jurisdiction, to prevent bank runs, and in some cases also to enforce policies on financial consumer protection and against bank fraud, money laundering, or terrorism financing. Central banks play a crucial role in macroeconomic forecasting, which is essential for guiding monetary policy decisions, especially during times of economic turbulence.
A reserve currency is a foreign currency that is held in significant quantities by central banks or other monetary authorities as part of their foreign exchange reserves. The reserve currency can be used in international transactions, international investments and all aspects of the global economy. It is often considered a hard currency or safe-haven currency.
Monetary policy is the policy adopted by the monetary authority of a nation to affect monetary and other financial conditions to accomplish broader objectives like high employment and price stability. Further purposes of a monetary policy may be to contribute to economic stability or to maintain predictable exchange rates with other currencies. Today most central banks in developed countries conduct their monetary policy within an inflation targeting framework, whereas the monetary policies of most developing countries' central banks target some kind of a fixed exchange rate system. A third monetary policy strategy, targeting the money supply, was widely followed during the 1980s, but has diminished in popularity since then, though it is still the official strategy in a number of emerging economies.
In macroeconomics, an open market operation (OMO) is an activity by a central bank to exchange liquidity in its currency with a bank or a group of banks. The central bank can either transact government bonds and other financial assets in the open market or enter into a repurchase agreement or secured lending transaction with a commercial bank. The latter option, often preferred by central banks, involves them making fixed period deposits at commercial banks with the security of eligible assets as collateral.
Digital currency is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic computer database owned by a company or bank, within digital files or even on a stored-value card.
Money creation, or money issuance, is the process by which the money supply of a country, or an economic or monetary region, is increased. In most modern economies, money is created by both central banks and commercial banks. Money issued by central banks is a liability, typically called reserve deposits, and is only available for use by central bank account holders, which are generally large commercial banks and foreign central banks.
International finance is the branch of monetary and macroeconomic interrelations between two or more countries. International finance examines the dynamics of the global financial system, international monetary systems, balance of payments, exchange rates, foreign direct investment, and how these topics relate to international trade.
The Central Bank of Nigeria (CBN) is the central bank and apex monetary authority of Nigeria established by the CBN Act of 1958 and commenced operations on 1 July 1959. The major regulatory objectives of the bank as stated in the CBN Act are to: maintain the external reserves of the country; promote monetary stability and a sound financial environment, and act as a banker of last resort and financial adviser to the federal government. The central bank's role as lender of last resort and adviser to the federal government has sometimes pushed it into murky political controversies. After the end of colonial rule, the desire of the government to become proactive in the development of the economy became visible, especially after the end of the Nigerian civil war, the bank followed the government's desire and took a determined effort to supplement any show shortfalls, credit allocations to the real sector. The bank became involved in lending directly to consumers, contravening its original intention to work through commercial banks in activities involving consumer lending.
Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically." A digital currency issued by a central bank is referred to as a central bank digital currency.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
Fiat money is a type of government-issued currency that is not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity. Fiat currency is typically designated by the issuing government to be legal tender, and is authorized by government regulation. Since the end of the Bretton Woods system in 1975, the major currencies in the world are fiat money.
Benoît Georges Cœuré is a French economist who has been serving as President of the Autorité de la concurence since 2022. He previously served as a member of the Executive Board of the European Central Bank from 2012 to 2019.
A stablecoin is a type of cryptocurrency where the value of the digital asset is supposed to be pegged to a reference asset, which is either fiat money, exchange-traded commodities, or another cryptocurrency.
Diem was a permissioned blockchain-based stablecoin payment system proposed by the American social media company Facebook. The plan also included a private currency implemented as a cryptocurrency.
The recent history of central bank digital currencies (CBDCs) has been marked by continuous exploration and development. By March 2024, over 130 countries were actively engaged in CBDC research with 3 countries, territories or currency unions having launched CBDCs, and 36 implementing pilot programs.
The general notion of cryptocurrencies in Europe denotes the processes of legislative regulation, distribution, circulation, and storage of cryptocurrencies in Europe. In April 2023, the EU Parliament passed the Markets in Crypto Act (MiCA) unified legal framework for crypto-assets within the European Union.
The Digital Rupee (e₹) or eINR or E-Rupee is a tokenised digital version of the Indian Rupee, issued by the Reserve Bank of India (RBI) as a central bank digital currency (CBDC). The Digital Rupee was proposed in January 2017 and launched on 1 December 2022. Digital Rupee is using blockchain distributed-ledger technology.
mBridge is a multiple central bank digital currency platform developed to support real-time, peer-to-peer, cross-border payments and foreign exchange transactions using CBDCs. Based on a blockchain called the mBridge Ledger, the platform is designed to ensure compliance with jurisdiction-specific policy and legal requirements, regulations, and governance needs.
The Digital Euro is the project of the European Central Bank (ECB), decided in July 2021, for the possible introduction of a central bank digital currency (CBDC). The aim is to develop a fast and secure electronic payment instrument that would complement the Euro for individuals and businesses in its existing form as cash and in bank accounts, and would be issued by the European System of Central Banks of the Eurozone.
