Central banks

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.^[1] 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 in most developed nations are usually set up to be institutionally independent from political interference,^[2]^[3]^[4] even though governments typically have governance rights over them, legislative bodies exercise scrutiny, and central banks frequently do show responsiveness to politics.^[5]^[6]^[7]

Issues like central bank independence, central bank policies and rhetoric in central bank governors discourse or the premises of macroeconomic policies^[8] (monetary and fiscal policy) of the state are a focus of contention and criticism by some policymakers,^[9] researchers^[10] and specialized business, economics and finance media.^[11]^[12]

Definition

The notion of central banks as a separate category from other banks has emerged gradually, and only fully coalesced in the 20th century. In the aftermath of World War I, leading central bankers of the United Kingdom and the United States respectively, Montagu Norman and Benjamin Strong, agreed on a definition of central banks that was both positive and normative.^[13]^: 4-5 Since that time, central banks have been generally distinguishable from other financial institutions, except under Communism in so-called single-tier banking systems such as Hungary's between 1950 and 1987, where the Hungarian National Bank operated alongside three other major state-owned banks.^[14] For earlier periods, what institutions do or do not count as central banks is often not univocal.

Correlatively, different scholars have held different views about the timeline of emergence of the first central banks. A widely held view in the second half of the 20th century has been that Stockholms Banco (est. 1657), as the original issuer of banknotes, counted as the oldest central bank, and that consequently its successor the Sveriges Riksbank was the oldest central bank in continuous operation, with the Bank of England as second-oldest and direct or indirect model for all subsequent central banks.^[15] That view has persisted in some early-21st-century publications.^[16] In more recent scholarship, however, the issuance of banknotes has often been viewed as just one of several techniques to provide central bank money, defined as financial money (in contrast to commodity money) of the highest quality. Under that definition, municipal banks of the late medieval and early modern periods, such as the Taula de canvi de Barcelona (est. 1401) or Bank of Amsterdam (est. 1609), issued central bank money and count as early central banks.^[17]

Naming

There is no universal terminology for the name of a central bank. Early central banks were often the only or principal formal financial institution in their jurisdiction, and were consequently often named "bank of" the relevant city's or country's name, e.g. the Bank of Amsterdam, Bank of Hamburg, Bank of England, or Wiener Stadtbank. Naming practices subsequently evolved as more central banks were established. They include, with references to the date when the bank acquired its current name:

"Bank of ": e.g. Bank of the United States (1791), Bank of France (1800), Bank of Java (1828), Bank of Japan (1882), Bank of Italy (1893), Bank of China (1912), Bank of Mexico (1925), Bank of Canada (1934), Bank of Korea (1950). The Bank of England has kept its original name of 1694, even though the Act of Union 1707 and Acts of Union 1800 expanded its remit to the broader United Kingdom.
"National Bank": e.g. National Bank of Belgium (1850), Bulgarian National Bank (1879), Swiss National Bank (1907), National Bank of Poland (1945), National Bank of Ukraine (1991).
"State Bank": e.g. State Bank of the Russian Empire (1860), State Bank of Pakistan (1948), State Bank of Vietnam (1951); also former central banks of Communist countries, e.g. the State Bank of the USSR (or Gosbank, 1922) or the State Bank of Czechoslovakia (1950). "People's Bank", also associated with Communism, is used by the People's Bank of China.
"Reserve Bank": in the U.S. Federal Reserve (1913) and thereafter British colonies or dominions, e.g. South African Reserve Bank (1921), Reserve Bank of New Zealand (1934), Reserve Bank of India (1935), Reserve Bank of Australia (1960), Reserve Bank of Fiji (1984)
"Central Bank": e.g. Central Bank of China (1924), Central Bank of the Republic of Turkey (1930), Central Bank of Argentina (1935), Central Bank of Ireland (1943), Central Bank of Paraguay (1952), Central Bank of Brazil (1964), European Central Bank (1998).
"Monetary Authority", e.g. Monetary Authority of Singapore (1971), Maldives Monetary Authority (1981), Hong Kong Monetary Authority (1993), Cayman Islands Monetary Authority (1997). The Saudi Arabian Monetary Authority (est. 1952) was renamed the Saudi Central Bank in 2020 but still uses the acronym SAMA.

In some cases, the local-language name is used in English-language practice, e.g. Sveriges Riksbank (est. 1668, current name in use since 1866), De Nederlandsche Bank (est. 1814), Deutsche Bundesbank (est. 1957), or Bangko Sentral ng Pilipinas (est. 1993).

Some commercial banks have names suggestive of central banks, even if they are not: examples are the State Bank of India and Central Bank of India, National Bank of Greece, Banco do Brasil, National Bank of Pakistan, Bank of China, Bank of Cyprus, or Bank of Ireland, as well as Deutsche Bank. Some but not all of these institutions had assumed central banking roles in the past.

The leading executive of a central bank is usually known as the Governor, President, or Chair.

History

The widespread adoption of central banking is a rather recent phenomenon. At the start of the 20th century, approximately two-thirds of sovereign states did not have a central bank. Waves of central bank adoption occurred in the interwar period and in the aftermath of World War II.^[18]

In the 20th century, central banks were often created with the intent to attract foreign capital, as bankers preferred to lend to countries with a central bank on the gold standard.^[18]

Background

The use of money as a unit of account predates history. Government control of money is documented in the ancient Egyptian economy (2750–2150 BCE).^[19] The Egyptians measured the value of goods with a central unit called shat. Like many other currencies, the shat was linked to gold. The value of a shat in terms of goods was defined by government administrations. Other cultures in Asia Minor later materialized their currencies in the form of gold and silver coins.^[20]

The issuance of paper currency is not to be equated with central banking, even though paper currency is a form of financial money (i.e. not commodity money). The difference is that government-issued paper currency, as present e.g. in China during the Yuan dynasty, is typically not freely convertible and thus of inferior quality, occasionally leading to hyperinflation.

From the 12th century, a network of professional banks emerged primarily in Southern Europe (including Southern France, with the Cahorsins).^[21] Banks could use book money to create deposits for their customers. Thus, they had the possibility to issue, lend and transfer money autonomously without direct control from political authorities.

Early municipal central banks

The Taula de canvi de Barcelona, established in 1401, is the first example of municipal, mostly public banks which pioneered central banking on a limited scale. It was soon emulated by the Bank of Saint George in the Republic of Genoa, first established in 1407, and significantly later by the Banco del Giro in the Republic of Venice and by a network of institutions in Naples that later consolidated into Banco di Napoli. Notable municipal central banks were established in the early 17th century in leading northwestern European commercial centers, namely the Bank of Amsterdam in 1609^[22] and the Hamburger Bank in 1619.^[23] These institutions offered a public infrastructure for cashless international payments.^[24] They aimed to increase the efficiency of international trade and to safeguard monetary stability. These municipal public banks thus fulfilled comparable functions to modern central banks.^[25]

Early national central banks

The Swedish central bank, known since 1866 as Sveriges Riksbank, was founded in Stockholm in 1664 from the remains of the failed Stockholms Banco and answered to the Riksdag of the Estates, Sweden's early modern parliament.^[26] One role of the Swedish central bank was lending money to the government.^[27]

The establishment of the Bank of England was devised by Charles Montagu, 1st Earl of Halifax, following a 1691 proposal by William Paterson.^[28] A royal charter was granted on 27 July 1694 through the passage of the Tonnage Act.^[29] The bank was given exclusive possession of the government's balances, and was the only limited-liability corporation allowed to issue banknotes.^[30]^{[page needed]} The early modern Bank of England, however, did not have all the functions of a today's central banks, e.g. to regulate the value of the national currency, to finance the government, to be the sole authorized distributor of banknotes, or to function as a lender of last resort to banks suffering a liquidity crisis.

In the early 18th century, a major experiment in national central banking failed in France with John Law's Banque Royale in 1720–1721. Later in the century, France had other attempts with the Caisse d'Escompte first created in 1767, and King Charles III established the Bank of Spain in 1782. The Russian Assignation Bank, established in 1769 by Catherine the Great, was an outlier from the general pattern of early national central banks in that it was directly owned by the Imperial Russian government, rather than private individual shareholders. In the nascent United States, Alexander Hamilton, as Secretary of the Treasury in the 1790s, set up the First Bank of the United States despite heavy opposition from Jeffersonian Republicans.^[31]

National central banks since 1800

Central banks were established in many European countries during the 19th century.^[32]^[33] Napoleon created the Banque de France in 1800, in order to stabilize and develop the French economy and to improve the financing of his wars.^[34] The Bank of France remained the most important Continental European central bank throughout the 19th century.^[35] The Bank of Finland was founded in 1812, soon after Finland had been taken over from Sweden by Russia to become a grand duchy.^[36] Simultaneously, a quasi-central banking role was played by a small group of powerful family-run banking networks, typified by the House of Rothschild, with branches in major cities across Europe, as well as Hottinguer in Switzerland and Oppenheim in Germany.^[37]^[38]

The theory of central banking, even though the name was not yet widely used, evolved in the 19th century. Henry Thornton, an opponent of the real bills doctrine, was a defender of the bullionist position and a significant figure in monetary theory. Thornton's process of monetary expansion anticipated the theories of Knut Wicksell regarding the "cumulative process which restates the Quantity Theory in a theoretically coherent form". As a response to a currency crisis in 1797, Thornton wrote in 1802 An Enquiry into the Nature and Effects of the Paper Credit of Great Britain, in which he argued that the increase in paper credit did not cause the crisis. The book also gives a detailed account of the British monetary system as well as a detailed examination of the ways in which the Bank of England should act to counteract fluctuations in the value of the pound.^[39]

In the United Kingdom until the mid-nineteenth century, commercial banks were able to issue their own banknotes, and notes issued by provincial banking companies were commonly in circulation.^[40] Many consider the origins of the central bank to lie with the passage of the Bank Charter Act 1844.^[15] Under the 1844 Act, bullionism was institutionalized in Britain,^[41] creating a ratio between the gold reserves held by the Bank of England and the notes that the bank could issue.^[42] The Act also placed strict curbs on the issuance of notes by the country banks.^[42] The Bank of England took over a role of lender of last resort in the 1870s after criticism of its lacklustre response to the failure of Overend, Gurney and Company. The journalist Walter Bagehot wrote on the subject in Lombard Street: A Description of the Money Market, in which he advocated for the bank to officially become a lender of last resort during a credit crunch, sometimes referred to as "Bagehot's dictum".

The 19th and early 20th centuries central banks in most of Europe and Japan developed under the international gold standard. Free banking or currency boards were common at the time.^{[citation needed]} Problems with collapses of banks during downturns, however, led to wider support for central banks in those nations which did not as yet possess them, for example in Australia.^{[citation needed]} In the United States, the role of a central bank had been ended in the so-called Bank War of the 1830s by President Andrew Jackson.^[43] In 1913, the U.S. created the Federal Reserve System through the passing of The Federal Reserve Act.^[44]

Following World War I, the Economic and Financial Organization (EFO) of the League of Nations, influenced by the ideas of Montagu Norman and other leading policymakers and economists of the time, took an active role to promote the independence of central banks, a key component of the economic orthodoxy the EFO fostered at the Brussels Conference (1920). The EFO thus directed the creation of the Oesterreichische Nationalbank in Austria, Hungarian National Bank, Bank of Danzig, and Bank of Greece, as well as comprehensive reforms of the Bulgarian National Bank and Bank of Estonia. Similar ideas were emulated in other newly independent European countries, e.g. for the National Bank of Czechoslovakia.^[13]

Brazil established a central bank in 1945, which was a precursor to the Central Bank of Brazil created twenty years later. After gaining independence, numerous African and Asian countries also established central banks or monetary unions. The Reserve Bank of India, which had been established during British colonial rule as a private company, was nationalized in 1949 following India's independence. By the early 21st century, most of the world's countries had a national central bank set up as a public sector institution, albeit with widely varying degrees of independence.

Colonial, extraterritorial and federal central banks

Before the near-generalized adoption of the model of national public-sector central banks, a number of economies relied on a central bank that was effectively or legally run from outside their territory. The first colonial central banks, such as the Bank of Java (est. 1828 in Batavia), Banque de l'Algérie (est. 1851 in Algiers), or Hongkong and Shanghai Banking Corporation (est. 1865 in Hong Kong), operated from the colony itself. Following the generalization of the transcontinental use of the electrical telegraph using submarine communications cable, however, new colonial banks were typically headquartered in the colonial metropolis; prominent examples included the Paris-based Banque de l'Indochine (est. 1875), Banque de l'Afrique Occidentale (est. 1901), and Banque de Madagascar (est. 1925). The Banque de l'Algérie's head office was relocated from Algiers to Paris in 1900.

In some cases, independent countries which did not have a strong domestic base of capital accumulation and were critically reliant on foreign funding found advantage in granting a central banking role to banks that were effectively or even legally foreign. A seminal case was the Imperial Ottoman Bank established in 1863 as a French-British joint venture, and a particularly egregious one was the Paris-based National Bank of Haiti (est. 1881) which captured significant financial resources from the economically struggling albeit independent nation of Haiti.^[45] Other cases include the London-based Imperial Bank of Persia, established in 1885, and the Rome-based National Bank of Albania, established in 1925. The State Bank of Morocco was established in 1907 with international shareholding and headquarters functions distributed between Paris and Tangier, a half-decade before the country lost its independence. In other cases, there have been organized currency unions such as the Belgium–Luxembourg Economic Union established in 1921, under which Luxembourg had no central bank, but that was managed by a national central bank (in that case the National Bank of Belgium) rather than a supranational one. The present-day Common Monetary Area of Southern Africa has comparable features.

Yet another pattern was set in countries where federated or otherwise sub-sovereign entities had wide policy autonomy that was echoed to varying degrees in the organization of the central bank itself. These included, for example, the Austro-Hungarian Bank from 1878 to 1918, the U.S. Federal Reserve in its first two decades, the Bank deutscher Länder between 1948 and 1957, or the National Bank of Yugoslavia between 1972 and 1993. Conversely, some countries that are politically organized as federations, such as today's Canada, Mexico, or Switzerland, rely on a unitary central bank.

Supranational central banks

In the second half of the 20th century, the dismantling of colonial systems left some groups of countries using the same currency even though they had achieved national independence. In contrast to the unraveling of Austria-Hungary and the Ottoman Empire after World War I, some of these countries decided to keep using a common currency, thus forming a monetary union, and to entrust its management to a common central bank. Examples include the Eastern Caribbean Currency Authority, the Central Bank of West African States, and the Bank of Central African States.

The concept of supranational central banking took a globally significant dimension with the Economic and Monetary Union of the European Union and the establishment of the European Central Bank (ECB) in 1998. In 2014, the ECB took an additional role of banking supervision as part of the newly established policy of European banking union.

Central bank mandates

Price stability

The primary role of central banks is usually to maintain price stability, as defined as a specific level of inflation. Inflation is defined either as the devaluation of a currency or equivalently the rise of prices relative to a currency. Most central banks currently have an inflation target close to 2%.

Since inflation lowers real wages, Keynesians view inflation as the solution to involuntary unemployment. However, "unanticipated" inflation leads to lender losses as the real interest rate will be lower than expected. Thus, Keynesian monetary policy aims for a steady rate of inflation.

Central banks as monetary authorities in representative states are intertwined through globalized financial markets. As a regulator of one of the most widespread currencies in the global economy, the US Federal Reserve plays an outsized role in the international monetary market. Being the main supplier and rate adjusted for US dollars, the Federal Reserve implements a set of requirements to control inflation and unemployment in the US.^[46]

High employment

Frictional unemployment is the time period between jobs when a worker is searching for, or transitioning from one job to another. Unemployment beyond frictional unemployment is classified as unintended unemployment. For example, structural unemployment is a form of unintended unemployment resulting from a mismatch between demand in the labour market and the skills and locations of the workers seeking employment. Macroeconomic policy generally aims to reduce unintended unemployment.

Keynes labeled any jobs that would be created by a rise in wage-goods (i.e., a decrease in real-wages) as involuntary unemployment:

Men are involuntarily unemployed if, in the event of a small rise in the price of wage-goods relatively to the money-wage, both the aggregate supply of labour willing to work for the current money-wage and the aggregate demand for it at that wage would be greater than the existing volume of employment.— John Maynard Keynes, The General Theory of Employment, Interest and Money p1

Economic growth

Economic growth can be enhanced by investment in capital, such as more or better machinery. A low interest rate implies that firms can borrow money to invest in their capital stock and pay less interest for it. Lowering the interest is therefore considered to encourage economic growth and is often used to alleviate times of low economic growth. On the other hand, raising the interest rate is often used in times of high economic growth as a contra-cyclical device to keep the economy from overheating and avoid market bubbles.

Further goals of monetary policy are stability of interest rates, of the financial market, and of the foreign exchange market. Goals frequently cannot be separated from each other and often conflict. Costs must therefore be carefully weighed before policy implementation.

Climate change

In the aftermath of the Paris agreement on climate change, a debate is now underway on whether central banks should also pursue environmental goals as part of their activities. In 2017, eight central banks formed the Network for Greening the Financial System (NGFS)^[47] to evaluate the way in which central banks can use their regulatory and monetary policy tools to support climate change mitigation. Today more than 70 central banks are part of the NGFS.^[48]

In January 2020, the European Central Bank has announced^[49] it will consider climate considerations when reviewing its monetary policy framework.

Proponents of "green monetary policy" are proposing that central banks include climate-related criteria in their collateral eligibility frameworks, when conducting asset purchases and also in their refinancing operations.^[50] But critics such as Jens Weidmann are arguing it is not central banks' role to conduct climate policy.^[51] China is among the most advanced central banks when it comes to green monetary policy.^[52] It has given green bonds preferential status to lower their yield^[53] and uses window policy to direct green lending.^[54]

The implications of potential stranded assets in the economy highlights one example of the embedded transition risk to climate change with potential cascade effects throughout the financial system.^[55]^[56]^[57] In response, four broad types of interventions including methodology development, investor encouragement, financial regulation and policy toolkits have been adopted by or suggested for central banks.^[18]

Achieving the 2°C threshold revolve in part around the development of climate-aligned financial regulations. A significant challenge lies in the lack of awareness among corporations and investors, driven by poor information flow and insufficient disclosure.^[18] To address this issue, regulators and central banks are promoting transparency, integrated reporting, and exposure specifications, with the goal of promoting long-term, low-carbon emission goals, rather than short-term financial objectives.^[18]^[58] These regulations aim to assess risk comprehensively, identifying carbon-intensive assets and increasing their capital requirements. This should result in high-carbon assets becoming less attractive while favoring low-carbon assets, which have historically been perceived as high-risk, and low volatility investment vehicles.^[18]^[59]^[60]

Quantitative easing is a potential measure that could be applied by Central banks to achieve a low-carbon transition.^[18] Although there is a historical bias toward high-carbon companies, included in Central banks portfolios due to their high credit ratings, innovative approaches to quantitative easing could invert this trend to favor low-carbon assets.^[18]^[61]^[62]

Considering the potential impact of central banks on climate change, it is important to consider the mandates of central banks. The mandate of a central bank can be narrow, meaning only a few objectives are given, limiting the ability of a central bank to include climate change in its policies.^[18] However, central bank mandates may not necessarily have to be modified to accommodate climate change-related activities.^[18] For example, the European Central Bank has incorporated carbon-emissions into its asset purchase criteria, despite its relatively narrow mandate that focuses on price stability.^[63]

Central bank operations

The functions of a central bank may include:

Monetary policy: by setting the official interest rate and controlling the money supply;
Financial stability: acting as a government's banker and as the bankers' bank ("lender of last resort");
Reserve management: managing a country's foreign-exchange and gold reserves and government bonds;
Banking supervision: regulating and supervising the banking industry, and currency exchange;
Payments system: managing or supervising means of payments and inter-banking clearing systems;
Coins and notes issuance;
Other functions of central banks may include economic research, statistical collection, supervision of deposit guarantee schemes, advice to government in financial policy.

Monetary policy

Central banks implement a country's chosen monetary policy.

Currency issuance

At the most basic level, monetary policy involves establishing what form of currency the country may have, whether a fiat currency, gold-backed currency (disallowed for countries in the International Monetary Fund), currency board or a currency union. When a country has its own national currency, this involves the issue of some form of standardized currency, which is essentially a form of promissory note: "money" under certain circumstances. Historically, this was often a promise to exchange the money for precious metals in some fixed amount. Now, when many currencies are fiat money, the "promise to pay" consists of the promise to accept that currency to pay for taxes.

A central bank may use another country's currency either directly in a currency union, or indirectly on a currency board. In the latter case, exemplified by the Bulgarian National Bank, Hong Kong and Latvia (until 2014), the local currency is backed at a fixed rate by the central bank's holdings of a foreign currency. Similar to commercial banks, central banks hold assets (government bonds, foreign exchange, gold, and other financial assets) and incur liabilities (currency outstanding). Central banks create money by issuing banknotes and loaning them to the government in exchange for interest-bearing assets such as government bonds. When central banks decide to increase the money supply by an amount which is greater than the amount their national governments decide to borrow, the central banks may purchase private bonds or assets denominated in foreign currencies.

The European Central Bank remits its interest income to the central banks of the member countries of the European Union. The US Federal Reserve remits most of its profits to the U.S. Treasury. This income, derived from the power to issue currency, is referred to as seigniorage, and usually belongs to the national government. The state-sanctioned power to create currency is called the Right of Issuance. Throughout history, there have been disagreements over this power, since whoever controls the creation of currency controls the seigniorage income. The expression "monetary policy" may also refer more narrowly to the interest-rate targets and other active measures undertaken by the monetary authority.

Monetary policy instruments

The primary tools available to central banks are open market operations (including repurchase agreements), reserve requirements, interest rate policy (through control of the discount rate), and control of the money supply.

A central bank affects the monetary base through open market operations, if its country has a well developed market for its government bonds. This entails managing the quantity of money in circulation through the buying and selling of various financial instruments, such as treasury bills, repurchase agreements or "repos", company bonds, or foreign currencies, in exchange for money on deposit at the central bank. Those deposits are convertible to currency, so all of these purchases or sales result in more or less base currency entering or leaving market circulation. For example, if the central bank wishes to decrease interest rates (executing expansionary monetary policy), it purchases government debt, thereby increasing the amount of cash in circulation or crediting banks' reserve accounts. Commercial banks then have more money to lend, so they reduce lending rates, making loans less expensive. Cheaper credit card interest rates increase consumer spending. Additionally, when business loans are more affordable, companies can expand to keep up with consumer demand. They ultimately hire more workers, whose incomes increase, which in its turn also increases the demand. This method is usually enough to stimulate demand and drive economic growth to a healthy rate. Usually, the short-term goal of open market operations is to achieve a specific short-term interest rate target. In other instances, monetary policy might instead entail the targeting of a specific exchange rate relative to some foreign currency or else relative to gold. For example, in the case of the United States the Federal Reserve targets the federal funds rate, the rate at which member banks lend to one another overnight; however, the monetary policy of China (since 2014) is to target the exchange rate between the Chinese renminbi and a basket of foreign currencies.

If the open market operations do not lead to the desired effects, a second tool can be used: the central bank can increase or decrease the interest rate it charges on discounts or overdrafts (loans from the central bank to commercial banks, see discount window). If the interest rate on such transactions is sufficiently low, commercial banks can borrow from the central bank to meet reserve requirements and use the additional liquidity to expand their balance sheets, increasing the credit available to the economy.

A third alternative is to change the reserve requirements. The reserve requirement refers to the proportion of total liabilities that banks must keep on hand overnight, either in its vaults or at the central bank. Banks only maintain a small portion of their assets as cash available for immediate withdrawal; the rest is invested in illiquid assets like mortgages and loans. Lowering the reserve requirement frees up funds for banks to increase loans or buy other profitable assets. This is expansionary because it creates credit. However, even though this tool immediately increases liquidity, central banks rarely change the reserve requirement because doing so frequently adds uncertainty to banks' planning. The use of open market operations is therefore preferred.

Unconventional monetary policy

Other forms of monetary policy, particularly used when interest rates are at or near 0% and there are concerns about deflation or deflation is occurring, are referred to as unconventional monetary policy. These include credit easing, quantitative easing, forward guidance, and signalling.^[64] In credit easing, a central bank purchases private sector assets to improve liquidity and improve access to credit. Signaling can be used to lower market expectations for lower interest rates in the future. For example, during the credit crisis of 2008, the US Federal Reserve indicated rates would be low for an "extended period", and the Bank of Canada made a "conditional commitment" to keep rates at the lower bound of 25 basis points (0.25%) until the end of the second quarter of 2010.

Some have envisaged the use of what Milton Friedman once called "helicopter money" whereby the central bank would make direct transfers to citizens^[65] in order to lift inflation up to the central bank's intended target. Such policy option could be particularly effective at the zero lower bound.^[66]

Central Bank Digital Currencies

Since 2017, prospect of implementing Central Bank Digital Currency (CBDC) has been in discussion.^[67] As of the end of 2018, at least 15 central banks were considering to implementing CBDC.^[68] Since 2014, the People's Bank of China has been working on a project for digital currency to make its own digital currency and electronic payment systems.^[69]^[70]
