Note that the Belarusian rubel is pegged to the euro, Russian rouble, and US dollar in a currency basket.
The United States dollar was established as the world's foremost reserve currency by the Bretton Woods Agreement of 1944. It claimed this status from sterling after the devastation of two world wars and the massive spending of the United Kingdom's gold reserves. Despite all links to gold being severed in 1971, the dollar continues to be the world's foremost reserve currency. Furthermore, the Bretton Woods Agreement also set up the global post-war monetary system by setting up rules, institutions and procedures for conducting international trade and accessing the global capital markets using the US dollar.
The US dollar is widely held by central banks, foreign companies and private individuals worldwide, in the form of eurodollar foreign deposit accounts (not to be confused with the euro), as well as in the form of US$100 notes, an estimated 75% of which are held overseas.[1] The US dollar is predominantly the standard currency unit in which goods are quoted and traded, and with which payments are settled in, in the global commodity markets.[2]
The US dollar is also the official currency in several countries and the de facto currency in many others, with Federal Reserve Notes (and, in a few cases, US coins) used in circulation.
The primary currency used for trade around the world, between Europe, Asia and the Americas had historically been the Spanish-American silver dollar, which created a global silver standard system from the 16th to 19th centuries, due to abundant silver supplies in Spanish America.[3] The US dollar itself was derived from this coin. The Spanish dollar was later displaced by sterling in the advent of the international gold standard in the last quarter of the 19th century.
The US dollar began to displace sterling as international reserve currency from the 1920s since it emerged from the First World War relatively unscathed and since the United States was a significant recipient of wartime gold inflows. [4] After the US emerged as an even stronger global superpower during the Second World War, the Bretton Woods Agreement of 1944 established the post-war international monetary system, with the US dollar ascending to become the world's primary reserve currency for international trade, and the only post-war currency linked to gold at $35 per troy ounce.[5] Despite all links to gold being severed in 1971, the dollar continues to play this role to this day.
International reserve currency
The US 100-dollar bill, the world's most recognizable reserve currency in physical form
Foreign companies, entities and private individuals hold US dollars in foreign deposit accounts called eurodollars (not to be confused with the euro), which are outside the jurisdiction of the Federal Reserve System. Private individuals also hold dollars outside the banking system mostly in the form of US$100 notes, of which 75% of its supply are held overseas.
Economist Paul Samuelson and others (including, at his death, Milton Friedman) have maintained that the overseas demand for dollars allows the United States to maintain persistent trade deficits without causing the value of the currency to depreciate or the flow of trade to readjust. But Samuelson stated in 2005 that at some uncertain future period these pressures would precipitate a run against the US dollar with serious global financial consequences.[10]
In August 2007, two scholars affiliated with the government of the People's Republic of China threatened to sell its substantial reserves in American dollars in response to American legislative discussion of trade sanctions designed to revalue the Chinese yuan.[11] The Chinese government denied that selling dollar-denominated assets would be an official policy in the foreseeable future. India and Russia have also announced moves to diversify reserves away from the US dollar.[12]
After the euro's share of global official foreign exchange reserves approached 25% as of year-end 2006 (vs 65% for the US dollar; see table in Reserve currency#Global currency reserves), former Federal Reserve Chairman Alan Greenspan said in September 2007 that it is "absolutely conceivable that the euro will replace the dollar as reserve currency, or will be traded as an equally important reserve currency".[13] As of 2021, however, none of this has come to fruition due to the European debt crisis which engulfed the PIIGS countries from 2009-2014. Instead the euro's stability and future existence was put into doubt, which reduced its share of global reserves to 19% as of year-end 2015 (vs 66% for USD). As of year-end 2020 these figures stand at 21% for EUR and 59% for USD.
The United States Government is capable of borrowing trillions of dollars from the global capital markets in US dollars issued by the Federal Reserve, which is itself under US government purview, at minimal interest rates and with virtually zero default risk. In contrast, foreign governments and corporations incapable of raising money in their own local currencies are forced to issue debt denominated in US dollars, along with its consequent higher interest rates and risks of default.[17] The United States's ability to borrow in its own currency without facing significant balance of payments crisis has been frequently described as its exorbitant privilege.[18]
The US Dollar Index (ticker: USDX) is the creation of the New York Board of Trade (NYBOT), renamed in September 2007 to ICE Futures US. It was established in 1973 for tracking the value of the USD against a basket of currencies, which, at that time, represented the largest trading partners of the United States. It began with 17 currencies from 17 nations, but the launch of the euro subsumed 12 of these into one, so the USDX tracks only six currencies today.
The Index is described by the ICE as "a geometrically-averaged calculation of six currencies weighted against the U.S. dollar."[19] The baseline of 100.00 on the USDX was set at its launch in March 1973. This event marks the watershed between the wider margins arrangement of the Smithsonian regime and the period of generalized floating that led up to the Second Amendment of the Articles of Agreement of the International Monetary Fund. Since 1973, the USDX has climbed as high as the 160s and drifted as low as the 70s.
The USDX has not been updated to reflect new trading realities in the global economy, where the bulk of trade has shifted strongly towards new partners like China and Mexico and oil-exporting countries while the United States has de-industrialized.
The US dollar is an official currency in Zimbabwe, along with the euro, sterling, the pula, the rand, and several other currencies. A series of Zimbabwean Bond Coins was put into circulation on 18 December 2014 in 1, 5, 10, and 25 cent denominations, and afterwards 50 cent and 1 dollar bonds coins, which are pegged at the same rate as American coins.
Some other countries link their currency to US dollar at a fixed exchange rate. The local currencies of Bermuda and the Bahamas can be freely exchanged at a 1:1 ratio for USD. Argentina used a fixed 1:1 exchange rate between the Argentine peso and the US dollar from 1991 until 2002. The currencies of Barbados and Belize are similarly convertible at an approximate 2:1 ratio. The Netherlands Antillean guilder (and its successor the Caribbean guilder) and the Aruban florin are pegged to the dollar at a fixed rate of 1:1.79. The East Caribbean dollar is pegged to the dollar at a fixed rate of 2.7:1, and is used by all of the countries and territories of the OECS other than the British Virgin Islands. In Lebanon, one dollar is equal to 15000 Lebanese pounds, and is used interchangeably with local currency as de facto legal tender.[22] The exchange rate between the Hong Kong dollar and the United States dollar has also been linked since 1983 at HK$7.8/USD, and pataca of Macau, pegged to Hong Kong dollar at MOP1.03/HKD, indirectly linked to the US dollar at roughly MOP8/USD. Several oil-producing Arab countries on the Persian Gulf, including Saudi Arabia, peg their currencies to the dollar, since the dollar is the currency used in the international oil trade.
The People's Republic of China's renminbi was informally and controversially pegged to the dollar in the mid-1990s at ¥ 8.28/USD. Likewise, Malaysia pegged its ringgit at RM3.8/USD in September 1998, after the financial crisis. On July 21, 2005, both countries removed their pegs and adopted managed floats against a basket of currencies. Kuwait did likewise on May 20, 2007.[23] However, after three years of slow appreciation, the Chinese yuan has been de facto re-pegged to the dollar since July 2008 at a value of ¥6.83/USD; although no official announcement had been made, the yuan has remained around that value within a narrow band since then, similar to the Hong Kong dollar.
Several countries use a crawling peg model, wherein currency is devalued at a fixed rate relative to the dollar. For example, the Nicaraguan córdoba is devalued by 5% per annum.[24]
Belarus, on the other hand, pegged its currency, the Belarusian rubel, to a basket of foreign currencies (US dollar, euro and Russian rouble) in 2009.[25] In 2011 this led to a currency crisis when the government became unable to honor its promise to convert Belarusian rubels to foreign currencies at a fixed exchange rate. BYR exchange rates dropped by two thirds, all import prices rose and living standards fell.[26]
In some countries, such as Costa Rica and Honduras, the US dollar is commonly accepted, although not officially regarded as legal tender. In Mexico's northern border area and major tourist zones, it is accepted as if it were a second legal currency. Many Canadian merchants close to the border, as well as large stores in big cities and major tourist hotspots in Peru also accept US dollars, though usually at a value that favours the merchant. In Cambodia, US notes circulate freely and are preferred over the Cambodian riel for large purchases,[27][28] with the riel used for change to break 1 USD. After the U.S. invasion of Afghanistan, US dollars were accepted as if legal tender, but in 2021 the Taliban government banned the use of foreign currencies.[29]
Not long after the introduction of the euro (€; ISO 4217 code EUR) as a cash currency in 2002, the dollar began to depreciate steadily in value, as it did against other major currencies. From 2003 to 2005, this depreciation continued, reflecting a widening current account deficit. Although the current account deficit began to stabilize in 2006 and 2007, depreciation persisted. The fallout from the subprime mortgage crisis in 2008 prompted the Federal Reserve to lower interest rates in September 2007,[30] and again in March 2008,[31] sending the euro to a record high of $1.6038, reached in July 2008. [32] In addition to the trade deficit, the U.S. dollar's decline was linked to a variety of other factors, including a major spike in oil prices.[33]
However, a sharp turnaround began in late 2008 with the onset of the global financial crisis. As investors sought out safe-haven investments in U.S. treasuries and Japanese government bonds from the financial turmoil, the Japanese yen and United States dollar sharply rose against other currencies, including the euro.[34] The European sovereign debt crisis that unfolded in 2010 sent the euro falling to a four-year low of $1.1877 on June 7, as investors considered the risk that certain Eurozone members may default on their government debt.[35] The euro's decline in 2008-2010 had erased half of its 2000-2008 rally.[32]
Chinese-issued U.S. dollar bonds
The issuance of U.S dollar-denominated bond issued by Chinese institutions doubled to $214 billion in 2017 as tighter domestic regulations and market conditions saw Chinese companies look offshore to conduct their fund-raising initiatives. This has far outpaced many of the other major foreign currency bonds issued in Asia in the last few years.
The anticipated continuation of a prudent monetary policy in China to curb financial risks and asset bubbles, along with the expectation of a stronger yuan will likely see Chinese companies to continue to issue U.S. dollar bonds.[36]
Major issuers of U.S. dollar denominated bonds have included Tencent Holdings Limited, Industrial and Commercial Bank of China Limited and Sinopec Group. In 2017, China's Ministry of Finance revealed plans to sell US$2 billion worth of U.S. dollar sovereign bonds in Hong Kong, its first dollar bond offering since October 2004.[37] The technology and communications sector in China is a taking significant share of the offshore U.S. dollar bond market. Tencent priced $5 billion of notes in January 2018 as a string of Asian technology firms continued to issue debt as market values swelled.[38]
U.S dollar-denominated bond issued by Chinese institutions has also been referred to as "Kungfu bonds",[39] a name born out of a consultation with more than 400 market participants across Asia by Bloomberg L.P.[40][41]
The euro is the official currency of 20 of the 27 member states of the European Union. This group of states is officially known as the euro area or, more commonly, the eurozone. The euro is divided into 100 euro cents.
Special drawing rights are supplementary foreign exchange reserve assets defined and maintained by the International Monetary Fund (IMF). SDRs are units of account for the IMF, and not a currency per se. They represent a claim to currency held by IMF member countries for which they may be exchanged. SDRs were created in 1969 to supplement a shortfall of preferred foreign exchange reserve assets, namely gold and U.S. dollars. The ISO 4217 currency code for special drawing rights is XDR and the numeric code is 960.
The renminbi, also known as the Chinese yuan, is the official currency of the People's Republic of China. The renminbi is issued by the People's Bank of China, the monetary authority of China. It is the world's fifth-most-traded currency as of April 2022.
The króna or krona is the currency of Iceland. One króna was formerly divided into 100 eyrir.
The New Zealand dollar is the official currency and legal tender of New Zealand, the Cook Islands, Niue, the Ross Dependency, Tokelau, and a British territory, the Pitcairn Islands. Within New Zealand, it is almost always abbreviated with the dollar sign ($). The abbreviations "$NZ" or "NZ$" are used when necessary to distinguish it from other dollar-denominated currencies.
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.
In finance, an exchange rate is the rate at which one currency will be exchanged for another currency. Currencies are most commonly national currencies, but may be sub-national as in the case of Hong Kong or supra-national as in the case of the euro.
Currency substitution is the use of a foreign currency in parallel to or instead of a domestic currency.
The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic action that together facilitate international flows of financial capital for purposes of investment and trade financing. Since emerging in the late 19th century during the first modern wave of economic globalization, its evolution is marked by the establishment of central banks, multilateral treaties, and intergovernmental organizations aimed at improving the transparency, regulation, and effectiveness of international markets. In the late 1800s, world migration and communication technology facilitated unprecedented growth in international trade and investment. At the onset of World War I, trade contracted as foreign exchange markets became paralyzed by money market illiquidity. Countries sought to defend against external shocks with protectionist policies and trade virtually halted by 1933, worsening the effects of the global Great Depression until a series of reciprocal trade agreements slowly reduced tariffs worldwide. Efforts to revamp the international monetary system after World War II improved exchange rate stability, fostering record growth in global finance.
The Hong Kong dollar is the official currency of Hong Kong. It is subdivided into 100 cents. Historically, it was also subdivided into 1000 mils. The Hong Kong Monetary Authority is the monetary authority of Hong Kong and the Hong Kong dollar.
In macroeconomics, hard currency, safe-haven currency, or strong currency is any globally traded currency that serves as a reliable and stable store of value. Factors contributing to a currency's hard status might include the stability and reliability of the respective state's legal and bureaucratic institutions, level of corruption, long-term stability of its purchasing power, the associated country's political and fiscal condition and outlook, and the policy posture of the issuing central bank.
In public finance, a currency board is a monetary authority which is required to maintain a fixed exchange rate with a foreign currency. This policy objective requires the conventional objectives of a central bank to be subordinated to the exchange rate target. In colonial administration, currency boards were popular because of the advantages of printing appropriate denominations for local conditions, and it also benefited the colony with the seigniorage revenue. However, after World War II many independent countries preferred to have central banks and independent currencies.
Eurocurrency is currency held on deposit outside its home market, i.e., held in banks located outside of the country which issues the currency. For example, a deposit of US dollars held in a bank in London, would be considered eurocurrency, as the US dollar is deposited outside of its home market.
The Convertibility plan was a plan by the Argentine Currency Board that pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth. While it initially met with considerable success, the board's actions ultimately failed. The peso was only pegged to the dollar until 2002.
The Somali shilling is the official currency of Somalia. It is subdivided into 100 senti, cents (English) or centesimi (Italian).
In international finance, a world currency, supranational currency, or global currency is a currency that would be transacted internationally, with no set borders.
The U.S. Dollar Index is an index of the value of the United States dollar relative to a basket of foreign currencies, often referred to as a basket of U.S. trade partners' currencies. The Index goes up when the U.S. dollar gains "strength" (value) when compared to other currencies.
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.
Currency intervention, also known as foreign exchange market intervention or currency manipulation, is a monetary policy operation. It occurs when a government or central bank buys or sells foreign currency in exchange for its own domestic currency, generally with the intention of influencing the exchange rate and trade policy.
The international status and usage of the euro has grown since its launch in 1999. When the euro formally replaced 12 currencies on 1 January 2002, it inherited their use in territories such as Montenegro and replaced minor currencies tied to pre-euro currencies, such as in Monaco. Four small states have been given a formal right to use the euro, and to mint their own coins, but all other usage outside the eurozone has been unofficial. With or without an agreement, these countries, unlike those in the eurozone, do not participate in the European Central Bank or the Eurogroup.
