Central bank
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]
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:
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.
Central bank mandates[edit]
Price stability[edit]
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[edit]
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:
