A monetary system is a system by which a government provides money in a country's economy. Modern monetary systems usually consist of the national treasury, the mint, the central banks and commercial banks. [1]
A commodity money system is a type of monetary system in which a commodity such as gold or seashells is made the unit of value and physically used as money. The money retains its value because of its physical properties. In some cases, a government may stamp a metal coin with a face, value or mark that indicates its weight or asserts its purity, but the value remains the same even if the coin is melted down.
One step away from commodity money is "commodity-backed money", also known as "representative money". Many currencies have consisted of bank-issued notes which have no inherent physical value, but which may be exchanged for a precious metal, such as gold. This is known as the gold standard. A silver standard was widespread after the fall of the Byzantine Empire, and lasted until 1935, when it was abandoned by China and Hong Kong.
A 20th-century variation was bimetallism, also called the "double standard", under which both gold and silver were legal tender. [2]
The alternative to a commodity money system is fiat money which is defined by a central bank and government law as legal tender even if it has no intrinsic value. Originally fiat money was paper currency or base metal coinage, but in modern economies it mainly exists as data such as bank balances and records of credit or debit card purchases, [3] and the fraction that exists as notes and coins is relatively small. [4] Money is mostly created by banks when they loan to customers. Put simply, banks lending currency to customers, subject to each bank's regulatory limit, is the principal mode of new deposit creation. [5]
The central bank does not directly fix the amount of currency in circulation. Money creation is primarily accomploshed via lending by commercial banks. Borrowers who receive the money created by new lending in turn affect the stock of money, as paying off debts removes money circulating. [6]
Although commercial banks create circulating money via lending, they cannot do so freely without limit. Commercial banks are required to maintain an on-hand reserve of funds equaling a portion of their total deposits banks (Large banks in the United States, for example, have a 10% reserve requirement. [7] ) Central banks set interest rates on funds available for commercial banks to borrow short-term from the central bank to meet their reserve requirement. This limits the amount of money the commercial banks are willing to lend, and thus create, as it affects the profitability of lending in a competitive market. [6]
In times of economic distress, central banks can act as a borrower to prompt the creation of new money as well; during quantitative easing they will buy government bonds and mortgage-backed securities. [8] [9]
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 gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.
Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves as well as their value in buying goods. This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, for which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.
In economics, deflation is a decrease in the general price level of goods and services. Deflation occurs when the inflation rate falls below 0%. Inflation reduces the value of currency over time, but deflation increases it. This allows more goods and services to be bought than before with the same amount of currency. Deflation is distinct from disinflation, a slowdown in the inflation rate; i.e., when inflation declines to a lower rate but is still positive.
Seigniorage, also spelled seignorage or seigneurage, is the difference between the value of money and the cost to produce and distribute it. The term can be applied in two ways:
The monetary policy of the United States is the set of policies which the Federal Reserve follows to achieve its twin objectives of high employment and stable inflation.
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.
Fractional-reserve banking is the system of banking in all countries worldwide, under which banks that take deposits from the public keep only part of their deposit liabilities in liquid assets as a reserve, typically lending the remainder to borrowers. Bank reserves are held as cash in the bank or as balances in the bank's account at the central bank. Fractional-reserve banking differs from the hypothetical alternative model, full-reserve banking, in which banks would keep all depositor funds on hand as reserves.
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.
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. Central banks can increase the quantity of reserve deposits directly, by making loans to account holders, purchasing assets from account holders, or by recording an asset, such as a deferred asset, and directly increasing liabilities. However, the majority of the money supply used by the public for conducting transactions is created by the commercial banking system in the form of commercial bank deposits. Bank loans issued by commercial banks expand the quantity of bank deposits.
The history of the United States dollar began with moves by the Founding Fathers of the United States of America to establish a national currency based on the Spanish silver dollar, which had been in use in the North American colonies of the Kingdom of Great Britain for over 100 years prior to the United States Declaration of Independence. The new Congress's Coinage Act of 1792 established the United States dollar as the country's standard unit of money, creating the United States Mint tasked with producing and circulating coinage. Initially defined under a bimetallic standard in terms of a fixed quantity of silver or gold, it formally adopted the gold standard in 1900, and finally eliminated all links to gold in 1971.
The silver standard is a monetary system in which the standard economic unit of account is a fixed weight of silver. Silver was far more widespread than gold as the monetary standard worldwide, from the Sumerians c. 3000 BC until 1873. Following the discovery in the 16th century of large deposits of silver at the Cerro Rico in Potosí, Bolivia, an international silver standard came into existence in conjunction with the Spanish pieces of eight. These silver dollar coins played the role of an international trading currency for nearly four hundred years.
Modern monetary theory or modern money theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. According to MMT, governments do not need to worry about accumulating debt since they can pay interest by printing money. MMT argues that the primary risk once the economy reaches full employment is inflation, which acts as the only constraint on spending. MMT also argues that inflation can be controlled by increasing taxes on everyone, to reduce the spending capacity of the private sector.
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.
Metallism is the economic principle that the value of money derives from the purchasing power of the commodity upon which it is based. The currency in a metallist monetary system may be made from the commodity itself or it may use tokens redeemable in that commodity. Georg Friedrich Knapp (1842–1926) coined the term "metallism" to describe monetary systems using coin minted in silver, gold or other metals.
Credit theories of money, also called debt theories of money, are monetary economic theories concerning the relationship between credit and money. Proponents of these theories, such as Alfred Mitchell-Innes, sometimes emphasize that money and credit/debt are the same thing, seen from different points of view. Proponents assert that the essential nature of money is credit (debt), at least in eras where money is not backed by a commodity such as gold. Two common strands of thought within these theories are the idea that money originated as a unit of account for debt, and the position that money creation involves the simultaneous creation of debt. Some proponents of credit theories of money argue that money is best understood as debt even in systems often understood as using commodity money. Others hold that money equates to credit only in a system based on fiat money, where they argue that all forms of money including cash can be considered as forms of credit money.
The United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.
Fiat money is a type of currency that is not backed by a precious metal, such as gold or silver, or backed 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 1971, the major currencies in the world are fiat money.
In macroeconomics, chartalism is a heterodox theory of money that argues that money originated historically with states' attempts to direct economic activity rather than as a spontaneous solution to the problems with barter or as a means with which to tokenize debt, and that fiat currency has value in exchange because of sovereign power to levy taxes on economic activity payable in the currency they issue.
