Pound sterling

The pound sterling (symbol: £; ISO code: GBP), known in some contexts simply as the pound or sterling, is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, Gibraltar, South Georgia and the South Sandwich Islands, the British Antarctic Territory, and Tristan da Cunha. It is subdivided into 100 "pence" (singular: "penny", abbreviated: "p"). The "pound sterling" is the oldest currency in continuous use. Some nations that do not use sterling also have currencies called the "pound".
Sterling is the fourth most-traded currency in the foreign exchange market, after the United States dollar, the euro, and the Japanese yen. Together with those three currencies and the Chinese yuan, it forms the basket of currencies which calculate the value of IMF special drawing rights. , sterling is also the fourth most-held reserve currency in global reserves.
The British Crown dependencies of Guernsey, Jersey and the Isle of Man produce their own local issues of sterling (the Guernsey pound, the Jersey pound and the Manx pound) which are considered fully equivalent to UK sterling in their respective regions. The pound sterling is also used in the British Overseas Territories Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), and in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound), others having transitioned to dollar currencies, such as Bermuda in 1970. The Bank of England is the central bank for the pound sterling, issuing its own banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. Sterling banknotes issued by other jurisdictions are not regulated by the Bank of England; their governments guarantee convertibility at par. The pound sterling was also used to varying degrees by colonies in the British Empire.
Names.
The full official name "pound sterling" (plural: "pounds sterling"), is used mainly in formal contexts and also when it is necessary to distinguish the United Kingdom currency from other currencies with the same name. Otherwise the term "pound" is normally used. The currency name is sometimes abbreviated to just "sterling", particularly in the wholesale financial markets, but not when referring to specific amounts; for example, "Payment is accepted in sterling" but never "These cost five sterling". The abbreviations "ster." and "stg." are sometimes used. The term "British pound" is sometimes used in less formal contexts, but it is not an official name of the currency.
Etymology.
There are various theories regarding the origin of the term "pound sterling". The Oxford English Dictionary states that the "most plausible" etymology is derivation from the Old English "steorra" for "star" with the added diminutive suffix "-ling", to mean "little star" and to refer to a silver penny of the English Normans.
Another argument that the Hanseatic League was the origin for both the origin of its definition and manufacture, and in its name is that the German name for the Baltic is "Ostsee", or "East Sea", and from this the Baltic merchants were called "Osterlings", or "Easterlings". In 1260, Henry III granted them a charter of protection and land for their Kontor, the Steelyard of London, which by the 1340s was also called "Easterlings Hall", or Esterlingeshalle. Because the League's money was not frequently debased like that of England, English traders stipulated to be paid in pounds of the "Easterlings", which was contracted to "'sterling".
Encyclopedia Britannica states the (pre-Norman) Anglo-Saxon kingdoms had silver coins called 'sterlings' and that the compound noun 'pound sterling' was derived from a pound (weight) of these sterlings.
Symbol.
The currency sign for the pound is , which is usually written with a single cross-bar (as on modern banknotes exclusively since 1975). A variation with a double cross-bar () has been used intermittently with since the earliest banknotes of 1725 when both were used. Historically, a simple capital L was used in newspapers, books and letters. The symbol derives from medieval Latin documents: the black-letter "L" (formula_1) was the abbreviation for "libra", the basic Roman unit of weight, which became an English unit of weight defined as the tower pound of sterling silver. In the British pre-decimal (duodecimal) currency system, the term £sd (or Lsd) for pounds, shillings and pence referred to the Roman words "libra", "solidus", and "denarius".
Currency code.
The ISO 4217 currency code is GBP, formed from "GB", the ISO 3166-1 alpha-2 code for the United Kingdom, and the first letter of "pound". Occasionally, the abbreviation "UKP" is used but this is non-standard because the ISO 3166 country code for the United Kingdom is GB (see Terminology of the British Isles). The Crown dependencies use their own (non-ISO) codes: GGP (Guernsey pound), JEP (Jersey pound) and IMP (Isle of Man pound). Stock prices are often quoted in pence, so traders may refer to pence sterling, GBX (sometimes GBp), when listing stock prices.
Cable.
The exchange rate of the pound sterling against the US dollar is referred to as "cable" in the wholesale foreign exchange markets. The origins of this term are attributed to the fact that in the 1800s, the GBP/USD exchange rate was transmitted via transatlantic cable. Forex traders of GBP/USD are sometimes referred to as "cable dealers". JPY/USD is the other currency pair with its own name, known as "fiber".
Quid (slang).
A common slang term for the pound sterling or pound is "quid", which is singular and plural, except in the common phrase "quids in!". The term may have come via Italian immigrants from "scudo", the name for a number of coins used in Italy until the 19th century; or from Latin 'quid' via the common phrase "quid pro quo", literally, "what for what", or, figuratively, "An equal exchange or substitution".
Subdivisions and other units.
Decimal coinage.
Since decimalisation on Decimal Day in 1971, the pound has been divided into 100 pence (denoted on coinage, until 1981, as "new pence"). The symbol for the penny is "p"; hence an amount such as 50p (£0.50) properly pronounced "fifty pence" is often pronounced "fifty pee" /fɪfti pi/. This also helped to distinguish between new and old pence amounts during the changeover to the decimal system. A decimal halfpenny was issued until 1984 but was removed due to having a higher cost to manufacture than its face value.
Pre-decimal.
Before decimalisation in 1971, the pound was divided into 20 shillings and each shilling into 12 pence, making 240 pence to the pound. The symbol for the shilling was ""s"."—not from the first letter of "shilling", but from the Latin "solidus". The symbol for the penny was ""d".", from the French "denier", from the Latin "denarius" (the solidus and denarius were Roman coins). A mixed sum of shillings and pence, such as 3 shillings and 6 pence, was written as "3/6" or "3"s". 6"d"." and spoken as "three and six" or "three and sixpence" except for "1/1," "2/1" etc., which were spoken as "one and a penny", "two and a penny", etc. 5 shillings, for example, was written as "5"s"." or, more commonly, "5/–".
Various coin denominations had, and in some cases continue to have, special names—such as florin (2s), crown (5s), half crown (2s6d). farthing (d), sovereign (£1) and guinea ("q.v."). See Coins of the pound sterling and List of British coins and banknotes for details.
By the 1950s, coins of Kings George III, George IV and William IV had disappeared from circulation, but coins (at least the penny) bearing the head of every British king or queen from Queen Victoria onwards could be found in circulation. Silver coins were replaced by those in cupro-nickel in 1947, and by the 1960s the silver coins were rarely seen. Silver/cupro-nickel shillings (from any period after 1816) and florins (2 shillings) remained legal tender after decimalisation (as 5p and 10p respectively) until 1990 and 1993 respectively, but are now officially demonetised.
History.
The pound sterling emerged after the adoption of Carolingian monetary system in England c 800 CE. Here is a summary of changes to its value in terms of silver or gold until 1914. 
Since the suspension of the gold standard in 1931 the pound sterling has been fiat money, with its value determined by its continued acceptance in the national and international economy. The pound sterling is the world's oldest currency that is still in use and that has been in continuous use since its inception.
Anglo-Saxon, c 800 CE.
The "pound" was a unit of account in Anglo-Saxon England, equal to 240 silver pence (the plural of penny) and equivalent to one pound weight of silver. It evolved into the modern British currency, the pound sterling.
The accounting system of four farthings = one penny, twelve pence = one shilling, twenty shillings = one pound, was adopted from that introduced by Charlemagne to the Frankish Empire (see livre carolingienne). The penny was abbreviated to 'd', from "denarius", Latin for penny; 's' from solidus, for shilling; and 'L' (subsequently £) from "Libra" or "Livre" for the pound.
The origins of sterling lie in the reign of King Offa of Mercia (757–796), who introduced the silver penny. It represented the "denarius" of the new currency system of Charlemagne's Frankish Empire. As in the Carolingian system, 240 pence weighed one pound, a unit corresponding to Charlemagne's "livre", with the shilling corresponding to Charlemagne's "solidus" and equal to twelve pence.
At the time of the penny's introduction, it weighed 22 troy grains of fine silver (32 tower grains or 1.458 g), so the Mercian pound weighed 5,400 troy grains (the Mercian pound became the basis of the tower pound, which also weighed 5,400 troy grains, equivalent to 7,680 tower grains or 349.9g). While fractional halfpennies and farthings worth penny were also minted, but small change was more commonly produced by cutting up a whole penny.
Medieval, 1158 CE.
The early pennies were struck from fine silver (as pure as was available). However, in 1158, a new coinage was introduced by King Henry II (known as the "Tealby penny") which was struck from 92.5% silver; hence 1.349 g fine silver in a penny. This coinage standard, called sterling silver, has been maintained until the 20th century. Sterling silver is harder than the 99.9% fine silver that was traditionally used and so sterling silver coins did not wear down as rapidly as fine silver coins.
The introduction in 1266 and subsequent popularity of the larger French coins led to additional denominations in the form of groats worth four pence and half groats worth two pence. A gold penny weighing twice the silver penny and valued at 20 silver pence was also issued in 1257 but was not successful.
The English penny remained nearly unchanged since c 800 CE and was a prominent exception in the progressive debasements of coinage which occurred in the rest of Europe. The Tower Pound (12 oz) originally of 240 pence was struck into just 243 pence as of 1279 CE. 
 The English groat denominated as 4 pence may be contrasted with the French gros tournois denominated 12 deniers (pence) and the Venetian grosso denominated 26 denari.
1351.
The introduction of gold coins received from Flanders as payment for English wool provided substantial economic and trade opportunities but also unsettled the pound sterling for the next 200 years. The first monetary changes in 1344 consisted of
The resulting gold-silver ratio of 1:12.5 was much higher than the ratio of 1:11 prevailing in the Continent, draining England of its silver coinage and requiring a more permanent remedy in 1351 in the form of
These gold nobles, together with half-nobles (40 pence) and farthings or quarter-nobles (20 pence), would became the first English gold coins produced in quantity.
1412.
The exigencies of the Hundred Years’ War during the reign of King Henry IV resulted in a further reduction in the English penny to 15 grains sterling silver (0.899 g fine silver) and the Half-Noble to 54 grains (3.481 g fine gold). The gold-silver ratio went down to 40*0.899/3.481 = 10.3.
After the French monetary reform of 1425, the gold half-noble (th pound, 40 pence) was worth close to one Livre Parisis (French pound) or 20 sols, while the silver half-groat (2 pence, fine silver 1.798 g) was worth close to 1 sol parisis (1.912 g). Also, after the Flemish monetary reform of 1434, the new Dutch Guilder (pound) was valued close to 40 pence while the Dutch stuiver (shilling) of 1.63 g fine silver was valued close to 2 pence sterling at 1.8 g. This approximate pairing of English half-nobles & half-groats to Continental livres and sols persisted up to the 1560s.
1464.
The Great Bullion Famine of the mid-15th century resulted in another reduction in the English penny to 12 grains sterling silver (0.719 g fine silver) and the introduction of a new Half-Angel gold coin of 40 grains (2.578 g), worth th pound or 40 pence. The latter approximately matched the then-reduced gold content of the Flemish Guilder & the Livre Parisis. The gold-silver ratio rose again to 40*0.719/2.578 = 11.2.
40 pence or th pound sterling made one Troy Ounce (480 grains, 31.1035 g) of sterling silver. It was approximately par with France's livre parisis of one French ounce (30.594 g), and in 1524 it would also be the model for a standardised German currency in the form of the Guldengroschen, which also weighed 1 German ounce of silver or .
Tudor, 1551.
The last significant depreciation in the pound sterling’s silver standard occurred amidst the 16th century influx of precious metals from the American continent arriving through the Habsburg Netherlands. The loose enforcement of monetary standards amongst its constituent provinces resulted in a significant rd reduction in the bullion content of the pound sterling in 1551.
The troy ounce of sterling silver was henceforth raised in price by 50% from 40 to 60 silver pennies (each penny weighing 8 grains sterling silver and containing fine silver). The gold half-angel of 40 grains ( fine gold) was raised in price from 40 pence to 60 pence (5 shillings or pound) and was henceforth known as the Crown.
Prior to 1551, English coin denominations closely matched with corresponding sol (2d) & livre (40d) denominations in the Continent, namely:
After 1551 new denominations were introduced, weighing similarly to 1464-issued coins but increased in value 1 times, namely:
1601–1816.
The silver basis of the pound sterling remained essentially unchanged until the 1816 introduction of the Gold Standard, save for the increase in the number of pennies in a troy ounce from 60 to 62 (hence, 0.464 g fine silver in a penny). Its gold basis remained unsettled, however, until the gold guinea was fixed at 21 shillings in 1717.
The guinea was introduced in 1663 with 44 guineas minted out of 12 troy ounces of 22-karat gold (hence, 7.6885 g fine gold) and initially worth £1 or 20 shillings. While its price in shillings was not legally fixed at first, its persistent trade value above 21 shillings reflected the poor state of clipped underweight silver coins tolerated for payment. Milled shillings of full weight were hoarded and exported to Europe, while clipped, hand-hammered shillings stayed in circulation.
During the time of Sir Isaac Newton, Master of the Mint, the gold guinea was fixed at 21 shillings in 1717. But without addressing the problem of underweight silver coins, and with the high resulting gold-silver ratio of 15.2, it gave the pound sterling a firmer footing in gold guineas rather than silver shillings, resulting in a de facto gold standard. Silver & copper tokens issued by private entities partly relieved the problem of small change until the Great Recoinage of 1816.
In line with Gresham's Law, English merchants sent silver abroad in payments, while goods for export were paid for with gold. Scotland, meanwhile, had its own Pound Scots. As a consequence of these flows of silver out and gold in, England was effectively on a gold standard. Trade with China aggravated this outflow, as the Chinese refused to accept anything but silver in payment for exports. From the mid-17th century, around of silver were received by China, principally from European powers, in exchange for Chinese tea and other goods. In order to trade with China, England had first to trade with the other European nations to receive silver, which led to the British East India Company redressing this trade imbalance through the indirect sale of opium to the Chinese.
Domestic demand for silver further reduced silver in circulation, as the improving fortunes of the merchant class led to increased demand for tableware. Silversmiths had always regarded coinage as a source of raw material, already verified for fineness by the government. As a result, sterling coins were being melted and fashioned into sterling silverware at an accelerating rate. An Act of the Parliament of England in 1697 tried to stem this tide by raising the minimum acceptable fineness on wrought plate from sterling's 92.5% to a new Britannia silver standard of 95.83%. Silverware made purely from melted coins would be found wanting when the silversmith took his wares to the Assay Office, thus discouraging the melting of coins.
Establishment of modern currency.
The Bank of England was founded in 1694, followed by the Bank of Scotland a year later. Both began to issue paper money.
Currency of Great Britain (1707) and the United Kingdom (1801).
The pound Scots once had much the same value as the pound sterling, but it suffered far higher devaluation until in the 17th century it was pegged to sterling at a value of 12 pounds Scots = 1 pound sterling.
In 1707, the Kingdom of England and the Kingdom of Scotland merged to form the Kingdom of Great Britain. In accordance with the Treaty of Union, the currency of Great Britain was sterling, with the pound Scots soon being replaced by sterling at the pegged value.
In 1801, Great Britain and the Kingdom of Ireland were united to form the United Kingdom of Great Britain and Ireland. However, the Irish pound continued to exist and was not replaced by sterling until January 1826. The conversion rate had long been 13 Irish pounds to 12 pounds sterling. In 1928, six years after the Anglo-Irish Treaty restored Irish autonomy within the British Empire, the Irish Free State re-established the Irish pound, pegged at par to sterling.
Use in the Empire.
Sterling circulated in much of the British Empire. In some parts, it was used alongside local currencies. For example, the gold sovereign was legal tender in Canada despite the use of the Canadian dollar. Several colonies and dominions adopted the pound as their own currency. These included Australia, Barbados, British West Africa, Cyprus, Fiji, British India, the Irish Free State, Jamaica, New Zealand, South Africa and Southern Rhodesia. Some of these retained parity with sterling throughout their existence (e.g. the South African pound), while others deviated from parity after the end of the gold standard (e.g. the Australian pound). These currencies and others tied to sterling constituted the sterling area.
The original English colonies on mainland North America were not party to the sterling area because the above-mentioned silver shortage in England coincided with these colonies' formative years. As a result of equitable trade (and rather less equitable piracy), the Spanish milled dollar became the most common coin within the English colonies.
Gold standard.
During the American War of Independence and the Napoleonic wars, Bank of England notes were legal tender, and their value floated relative to gold. The Bank also issued silver tokens to alleviate the shortage of silver coins. In 1816, the gold standard was adopted officially, with silver coins minted at a rate of 66 shillings to a troy pound (weight) of sterling silver, thus rendering them as "token" issues (i.e. not containing their value in precious metal). In 1817, the sovereign was introduced, valued at 20 shillings. Struck in 22‑karat gold, it contained 113 grains or of fine gold and replaced the guinea as the standard British gold coin without changing the gold standard. 
By the 19th century, pound sterling notes were widely accepted outside Britain. The American Nellie Bly carried Bank of England notes on her 1889–1890 trip around the world in 72 days. During the late 19th and early 20th centuries, many other countries adopted the gold standard. As a consequence, conversion rates between different currencies could be determined simply from the respective gold standards. The pound sterling was equal to 4.87 United States dollars, 4.87 Canadian dollars, 12.11 Dutch guilders, 25.22 French francs (or equivalent currencies in the Latin Monetary Union), 20.43 German marks, 9.46 Russian Rubles or 24.02 Austro-Hungarian krone. After the International Monetary Conference of 1867 in Paris, the possibility of the UK joining the Latin Monetary Union was discussed, and a Royal Commission on International Coinage examined the issues, resulting in a decision against joining monetary union.
The gold standard was suspended at the outbreak of the war in 1914, with Bank of England and Treasury notes becoming legal tender. Before World War I, the United Kingdom had one of the world's strongest economies, holding 40% of the world's overseas investments. But after the end of the war, the country was indebted: Britain owed £850 million (about £ today) with interest costing the country some 40% of all government spending. To try to resume stability, a version of the gold standard was reintroduced in 1925, under which the currency was fixed to gold at its pre-war peg, but one could only exchange currency for gold bullion, not for coins. This was abandoned on 21 September 1931, during the Great Depression, and sterling suffered an initial devaluation of some 25%.
Bretton Woods.
In 1940, an agreement with the US pegged the pound to the U.S. dollar at a rate of £1 = $4.03. (Only the year before, it had been $4.86.) This rate was maintained through the Second World War and became part of the Bretton Woods system which governed post-war exchange rates. Under continuing economic pressure, and despite months of denials that it would do so, on 19 September 1949 the government devalued the pound by 30.5% to $2.80. The move prompted several other currencies to be devalued against the dollar.
Operation Bernhard was the codename of a secret Nazi plan devised during the Second World War by the RSHA and the SS to destabilise the British economy via economic warfare by flooding the global economy and the British Empire with forged Bank of England £5, £10, £20, and £50 notes.
In 1961, 1964, and 1966, the pound came under renewed pressure, as speculators were selling pounds for dollars. In summer 1966, with the value of the pound falling in the currency markets, exchange controls were tightened by the Wilson government. Among the measures, tourists were banned from taking more than £50 out of the country in travellers' cheques and remittances, plus £15 in cash; this restriction was not lifted until 1979. The pound was devalued by 14.3% to $2.40 on 18 November 1967.
Decimalisation.
Until decimalisation, amounts were stated in pounds, shillings, and pence, with various widely understood notations. The same amount could be stated as 32s 6d, 32/6, £1 12s 6d, or £1/12/6. It was customary to specify some prices (for example professional fees and auction prices for works of art) in guineas (one guinea was 21 shillings) although guinea coins were no longer in use.
Formal parliamentary proposals to decimalise sterling were first made in 1824 when Sir John Wrottesley, MP for Staffordshire, asked in the British House of Commons whether consideration had been given to decimalising the currency. Wrottesley raised the issue in the House of Commons again in 1833, and it was again raised by John Bowring, MP for Kilmarnock Burghs, in 1847 whose efforts led to the introduction in 1848 of what was in effect the first decimal coin in the United Kingdom, the florin, valued at one-tenth of a pound sterling. However, full decimalisation was resisted, although the florin coin, re-designated as "ten new pence", survived the transfer to a full decimal system in 1971, with examples surviving in British coinage until 1993.
John Benjamin Smith, MP for Stirling Burghs, raised the issue of full decimalisation again in Parliament in 1853, resulting in the Chancellor of the Exchequer, William Gladstone, announcing soon afterwards that "the great question of a decimal coinage" was "now under serious consideration". A full proposal for the decimalisation of sterling was then tabled in the House of Commons in June 1855, by William Brown, MP for Lancashire Southern, with the suggestion that the pound sterling be divided into one thousand parts, each called a "mil", or alternatively a farthing, as the pound was then equivalent to 960 farthings which could easily be rounded up to one thousand farthings in the new system. This did not result in the conversion of the pound sterling into a decimal system, but it was agreed to establish a Royal Commission to look into the issue. However, largely due to the hostility to decimalisation of two of the appointed commissioners, Lord Overstone (a banker) and John Hubbard (Governor of the Bank of England), decimalisation in Britain was effectively quashed for over a hundred years.
However, the pound sterling was decimalised in various British colonial territories before the United Kingdom (and in several cases in line with William Brown's proposal that the pound be divided into 1,000 parts, called mils). These included Hong Kong from 1863 to 1866; Cyprus from 1955 until 1960 (and continued on the island as the division of the Cypriot pound until 1983); and the Palestine Mandate from 1926 until 1948.
Towards the end of the Second World War, various attempts to decimalise the pound sterling in the United Kingdom were made. Later, in 1966, the British government decided to include in the Queen's Speech a plan to convert the pound into a decimal currency. As a result of this, on 15 February 1971, the UK decimalised the pound sterling, replacing the shilling and the penny with a single subdivision, the new penny. For example, a price tag of £1 12s 6d became . The word "new" was omitted from coins minted after 1981.
Free-floating pound.
With the breakdown of the Bretton Woods system, the pound floated from August 1971 onwards. At first, it appreciated a little, rising to almost $2.65 in March 1972 from $2.42, the upper bound of the band in which it had been fixed. The sterling area effectively ended at this time, when the majority of its members also chose to float freely against the pound and the dollar.
1976 sterling crisis.
James Callaghan became Prime Minister in 1976. He was immediately told the economy was facing huge problems, according to documents released in 2006 by the National Archives. The effects of the 1973 oil crisis were still being felt, with inflation rising to nearly 27% in 1975. Financial markets were beginning to believe the pound was overvalued, and in April that year "The Wall Street Journal" advised the sale of sterling investments in the face of high taxes, in a story that ended with "goodbye, Great Britain. It was nice knowing you". At the time the UK government was running a budget deficit, and Labour's strategy emphasised high public spending. Callaghan was told there were three possible outcomes: a disastrous free fall in sterling, an internationally unacceptable siege economy, or a deal with key allies to prop up the pound while painful economic reforms were put in place. The US government feared the crisis could endanger NATO and the European Economic Community (EEC), and in light of this the US Treasury set out to force domestic policy changes. In November 1976 the International Monetary Fund (IMF) announced the conditions for a loan, including deep cuts in public expenditure.
1979–1989.
The Conservative Party was elected to office in 1979, on a programme of fiscal austerity. Initially, the pound rocketed, moving above US$2.40, as interest rates rose in response to the monetarist policy of targeting money supply. The high exchange rate was widely blamed for the deep recession of 1981. Sterling fell sharply after 1980; at its lowest, the pound stood at just $1.03 in March 1985, before rising to $1.70 in December 1989.
Following the Deutsche Mark.
In 1988, Margaret Thatcher's Chancellor of the Exchequer, Nigel Lawson, decided that the pound should "shadow" the West German Deutsche Mark (DM), with the unintended result of a rapid rise in inflation as the economy boomed due to low interest rates. (For ideological reasons, the Conservative Government declined to use alternative mechanisms to control the explosion of credit. For this reason, former Prime Minister Edward Heath referred to Lawson as a "one club golfer".)
Following German reunification in 1990, the reverse held true, as high German borrowing costs to fund Eastern reconstruction, exacerbated by the political decision to convert the Ostmark to the DM on a 1:1 basis, meant that interest rates in other countries shadowing the DM, especially the UK, were far too high relative to domestic circumstances, leading to a housing decline and recession.
Following the European Currency Unit.
On 8 October 1990 the Conservative government (Third Thatcher ministry) decided to join the European Exchange Rate Mechanism (ERM), with the pound set at DM2.95. However, the country was forced to withdraw from the system on "Black Wednesday" (16 September 1992) as Britain's economic performance made the exchange rate unsustainable.
"Black Wednesday" saw interest rates jump from 10% to 15% in an unsuccessful attempt to stop the pound from falling below the ERM limits. The exchange rate fell to DM2.20. Those who had argued for a lower GBP/DM exchange rate were vindicated since the cheaper pound encouraged exports and contributed to the economic prosperity of the 1990s.
Following inflation targets.
In 1997, the newly elected Labour government handed over day-to-day control of interest rates to the Bank of England (a policy that had originally been advocated by the Liberal Democrats). The Bank is now responsible for setting its base rate of interest so as to keep inflation (as measured by the Consumer Price Index (CPI)) very close to 2% per annum. Should CPI inflation be more than one percentage point above or below the target, the governor of the Bank of England is required to write an open letter to the Chancellor of the Exchequer explaining the reasons for this and the measures which will be taken to bring this measure of inflation back in line with the 2% target. On 17 April 2007, annual CPI inflation was reported at 3.1% (inflation of the Retail Prices Index was 4.8%). Accordingly, and for the first time, the Governor had to write publicly to the government explaining why inflation was more than one percentage point higher than its target.
Euro.
In 2007, Gordon Brown, then Chancellor of the Exchequer, ruled out membership in the eurozone for the foreseeable future, saying that the decision not to join had been right for Britain and for Europe.
On 1 January 2008, with the Republic of Cyprus switching its currency from the Cypriot pound to the euro, the British sovereign bases on Cyprus (Akrotiri and Dhekelia) followed suit, making the Sovereign Base Areas the only territory under British sovereignty to officially use the euro.
The government of former Prime Minister Tony Blair had pledged to hold a public referendum to decide on the adoption of the Euro should "five economic tests" be met, to increase the likelihood that any adoption of the euro would be in the national interest. In addition to these internal (national) criteria, the UK would have to meet the European Union's economic convergence criteria (Maastricht criteria) before being allowed to adopt the euro. The Conservative and Liberal Democrat coalition government (2010–2015) ruled out joining the euro for that parliamentary term.
The idea of replacing the pound with the euro was always controversial with the British public, partly because of the pound's identity as a symbol of British sovereignty and because it would, according to some critics, have led to suboptimal interest rates, harming the British economy. In December 2008, the results of a BBC poll of 1000 people suggested that 71% would vote no to the euro, 23% would vote yes, while 6% said they were unsure. The pound did not join the Second European Exchange Rate Mechanism (ERM II) after the euro was created. Denmark and the UK had opt-outs from entry to the euro. Theoretically, every EU nation but Denmark must eventually sign up.
As a member of the European Union, the United Kingdom could have adopted the euro as its currency. However, the subject was always politically controversial, and the UK negotiated an opt-out on this issue. Following the UK's withdrawal from the EU, on 31 January 2020, the Bank of England ended its membership of the European System of Central Banks, and shares in the European Central Bank were reallocated to other EU banks.
Recent exchange rates.
The pound and the euro fluctuate in value against one another, although there may be correlation between movements in their respective exchange rates with other currencies such as the US dollar. Inflation concerns in the UK led the Bank of England to raise interest rates in late 2006 and 2007. This caused the pound to appreciate against other major currencies and, with the US dollar depreciating at the same time, the pound hit a 15-year high against the US dollar on 18 April 2007, reaching US$2 the day before, for the first time since 1992. The pound and many other currencies continued to appreciate against the dollar; sterling hit a 26-year high of US$2.1161 on 7 November 2007 as the dollar fell worldwide. From mid-2003 to mid-2007, the pound/euro rate remained within a narrow range (€1.45 ± 5%).
Following the global financial crisis in late 2008, the pound depreciated sharply, reaching $1.38 (US) on 23 January 2009 and falling below €1.25 against the euro in April 2008. There was a further decline during the remainder of 2008, most dramatically on 29 December when its euro rate hit an all-time low at €1.0219, while its US dollar rate depreciated. The pound appreciated in early 2009, reaching a peak against the euro of €1.17 in mid-July. In the following months the pound remained broadly steady against the euro, with the pound's valued on 27 May 2011 at €1.15 and US$1.65.
On 5 March 2009, the Bank of England announced that it would pump £75 billion of new capital into the British economy, through a process known as quantitative easing (QE). This was the first time in the United Kingdom's history that this measure had been used, although the Bank's Governor Mervyn King suggested it was not an experiment.
The process saw the Bank of England creating new money for itself, which it then used to purchase assets such as government bonds, secured commercial paper, or corporate bonds. The initial amount stated to be created through this method was £75 billion, although Chancellor of the Exchequer Alistair Darling had given permission for up to £150 billion to be created if necessary. It was expected that the process would continue for three months, with results only likely in the long term. By 5 November 2009, some £175 billion had been injected using QE, and the process remained less effective in the long term. In July 2012, the final increase in QE meant it had peaked at £375 billion, then holding solely UK Government bonds, representing one third of the UK national debt.
The result of the 2016 UK referendum on EU membership caused a major decline in the pound against other world currencies as the future of international trade relationships and domestic political leadership became unclear. The referendum result weakened sterling against the euro by 5% overnight. The night before the vote, the pound was trading at €1.30; the next day, this had fallen to €1.23. By October 2016, the exchange rate was €1.12 to the pound, a fall of 14% since the referendum. By the end of August 2017 the pound was even lower, at €1.08. Against the US dollar, meanwhile, the pound fell from $1.466 to $1.3694 when the referendum result was first revealed, and down to $1.2232 by October 2016, a fall of 16%.
Annual inflation rate.
The Bank of England had stated in 2009 that the decision had been taken to prevent the rate of inflation falling below the 2% target rate. Mervyn King, the Governor of the Bank of England, had also suggested there were no other monetary options left, as interest rates had already been cut to their lowest level ever (0.5%) and it was unlikely that they would be cut further.
The inflation rate rose in following years, reaching 5.2% per year (based on the Consumer Price Index) in September 2011, then decreased to around 2.5% the following year.
Coins.
Pre-decimal coins.
The silver penny (plural: "pence"; abbreviation: "d") was the principal and often the only coin in circulation from the 8th century until the 13th century. Although some fractions of the penny were struck (see farthing and halfpenny), it was more common to find pennies cut into halves and quarters to provide smaller change. Very few gold coins were struck, with the gold penny (worth 20 silver pence) a rare example. However, in 1279, the "groat", worth 4d, was introduced, with the half groat following in 1344. 1344 also saw the establishment of a gold coinage with the introduction (after the failed gold florin) of the "noble" worth six shillings and eight pence (6/8) (i.e. 3 nobles to the pound), together with the half and quarter noble. Reforms in 1464 saw a reduction in value of the coinage in both silver and gold, with the noble renamed the "ryal" and worth 10/– (i.e. 2 to the pound) and the "angel" introduced at the noble's old value of 6/8.
The reign of Henry VII saw the introduction of two important coins: the shilling (abbr.: "s"; known as the "testoon", equivalent to twelve pence) in 1487 and the pound (known as the "sovereign", abbr.: "£" or "L", equivalent to twenty shillings) in 1489. In 1526, several new denominations of gold coins were added, including the "crown" and "half crown", worth five shillings ("5/–") and two shillings and six pence ("2/6", "two and six") respectively. Henry VIII's reign (1509–1547) saw a high level of debasement which continued into the reign of Edward VI (1547–1553). This debasement was halted in 1552, and new silver coinage was introduced, including coins for 1d, 2d, 3d, 4d and 6d, 1/–, 2/6 and 5/–. In the reign of Elizabeth I (1558–1603), silver d and d coins were added, but these denominations did not last. Gold coins included the half-crown, crown, angel, half-sovereign (10/–) and sovereign (£1). Elizabeth's reign also saw the introduction of the horse-drawn screw press to produce the first "milled" coins.
Following the succession of the Scottish King James VI to the English throne, a new gold coinage was introduced, including the "spur ryal" (15/–), the "unite" (20/–) and the "rose ryal" (30/–). The "laurel", worth 20/–, followed in 1619. The first base metal coins were also introduced: tin and copper farthings. Copper halfpenny coins followed in the reign of Charles I. During the English Civil War, a number of siege coinages were produced, often in unusual denominations.
Following the restoration of the monarchy in 1660, the coinage was reformed, with the ending of production of hammered coins in 1662. The "guinea" was introduced in 1663, soon followed by the , 2 and 5 guinea coins. The silver coinage consisted of denominations of 1d, 2d, 3d, 4d and 6d, 1/–, 2/6 and 5/–. Due to the widespread export of silver in the 18th century, the production of silver coins gradually came to a halt, with the half crown and crown not issued after the 1750s, the 6d and 1/– stopping production in the 1780s. In response, copper 1d and 2d coins and a gold guinea (7/–) were introduced in 1797. The copper penny was the only one of these coins to survive long.
To alleviate the shortage of silver coins, between 1797 and 1804, the Bank of England counterstamped Spanish dollars (8 reales) and other Spanish and Spanish colonial coins for circulation. A small counterstamp of the King's head was used. Until 1800, these circulated at a rate of 4/9 for 8 reales. After 1800, a rate of 5/- for 8 reales was used. The Bank then issued silver tokens for 5/– (struck over Spanish dollars) in 1804, followed by tokens for 1/6 and 3/– between 1811 and 1816.
In 1816, a new silver coinage was introduced in denominations of 6d, 1/–, 2/6 (half-crown) and 5/– (crown). The crown was only issued intermittently until 1900. It was followed by a new gold coinage in 1817 consisting of 10/– and £1 coins, known as the half sovereign and sovereign. The silver 4d coin was reintroduced in 1836, followed by the 3d in 1838, with the 4d coin issued only for colonial use after 1855. In 1848, the 2/– "florin" was introduced, followed by the short-lived double florin in 1887. In 1860, copper was replaced by bronze in the farthing (quarter penny, d), halfpenny and penny.
During the First World War, production of the sovereign and half-sovereign was suspended, and although the gold standard was later restored, the coins saw little circulation thereafter. In 1920, the silver standard, maintained at .925 since 1552, was reduced to .500. In 1937, a nickel-brass 3d coin was introduced; the last silver 3d coins were issued seven years later. In 1947, the remaining silver coins were replaced with cupro-nickel, with the exception of Maundy coinage which was then restored to .925. Inflation caused the farthing to cease production in 1956 and be demonetised in 1960. In the run-up to decimalisation, the halfpenny and half-crown were demonetised in 1969.
Decimal coins.
British coinage timeline:
, the oldest circulating coins in the UK are the 1p and 2p copper coins introduced in 1971. No other coins from before 1982 are in circulation. Prior to the withdrawal from circulation in 1992, the oldest circulating coins had usually dated from 1947: although older coins (shilling; florin, sixpence to 1980) were still legal tender, inflation meant that their silver content was worth more than their face value, which meant that they tended to be removed from circulation. Before decimalisation in 1971, a handful of change might have contained coins 100 or more years old, bearing any of five monarchs' heads, especially in the copper coins.
Banknotes.
The first sterling notes were issued by the Bank of England shortly after its foundation in 1694. Denominations were initially handwritten on the notes at the time of issue. From 1745, the notes were printed in denominations between £20 and £1000, with any odd shillings added by hand. £10 notes were added in 1759, followed by £5 in 1793 and £1 and £2 in 1797. The lowest two denominations were withdrawn after the end of the Napoleonic wars. In 1855, the notes were converted to being entirely printed, with denominations of £5, £10, £20, £50, £100, £200, £300, £500 and £1000 issued.
The Bank of Scotland began issuing notes in 1695. Although the pound Scots was still the currency of Scotland, these notes were denominated in sterling in values up to £100. From 1727, the Royal Bank of Scotland also issued notes. Both banks issued some notes denominated in guineas as well as pounds. In the 19th century, regulations limited the smallest note issued by Scottish banks to be the £1 denomination, a note not permitted in England.
With the extension of sterling to Ireland in 1825, the Bank of Ireland began issuing sterling notes, later followed by other Irish banks. These notes included the unusual denominations of 30/- and £3. The highest denomination issued by the Irish banks was £100.
In 1826, banks at least from London were given permission to issue their own paper money. From 1844, new banks were excluded from issuing notes in England and Wales but not in Scotland and Ireland. Consequently, the number of private banknotes dwindled in England and Wales but proliferated in Scotland and Ireland. The last English private banknotes were issued in 1921.
In 1914, the Treasury introduced notes for 10/- and £1 to replace gold coins. These circulated until 1928 when they were replaced by Bank of England notes. Irish independence reduced the number of Irish banks issuing sterling notes to five operating in Northern Ireland. The Second World War had a drastic effect on the note production of the Bank of England. Fearful of mass forgery by the Nazis (see Operation Bernhard), all notes for £10 and above ceased production, leaving the bank to issue only 10/-, £1 and £5 notes. Scottish and Northern Irish issues were unaffected, with issues in denominations of £1, £5, £10, £20, £50 and £100.
The Bank of England reintroduced £10 notes in 1964. In 1969, the 10/- note was replaced by the 50p coin to prepare for decimalisation. £20 Bank of England notes were reintroduced in 1970, followed by £50 in 1981. A £1 coin was introduced in 1983, and Bank of England £1 notes were withdrawn in 1988. Scottish and Northern Irish banks followed, with only the Royal Bank of Scotland continuing to issue this denomination.
UK notes include raised print (e.g. on the words "Bank of England"); watermarks; embedded metallic thread; holograms; and fluorescent ink visible only under UV lamps. Three printing techniques are involved: offset litho, intaglio and letterpress; and the notes incorporate a total of 85 specialized inks.
The Bank of England produces notes named "giant" and "titan". A giant is a one million pound note, and a titan is a one hundred million pound bank note, of which there are about 40. Giants and titans are used only within the banking system.
Polymer banknotes.
The Northern Bank £5 note, issued by (Northern Ireland's) Northern Bank (now Danske Bank) in 2000, was the only polymer banknote in circulation until 2016. The Bank of England introduced £5 polymer banknotes in September 2016, and the paper £5 notes were withdrawn on 5 May 2017. A polymer £10 banknote was introduced on 14 September 2017, and the paper note was withdrawn on 1 March 2018. A polymer £20 banknote was introduced on 20 February 2020, to be followed by a polymer £50 in 2021.
Monetary policy.
As the central bank of the United Kingdom which has been delegated authority by the government, the Bank of England sets the monetary policy for the British pound by controlling the amount of money in circulation. It has a monopoly on the issuance of banknotes in England and Wales and regulates the amount of banknotes issued by seven authorized banks in Scotland and Northern Ireland. HM Treasury has reserve powers to give orders to the committee "if they are required in the public interest and by extreme economic circumstances" but such orders must be endorsed by Parliament within 28 days.
Unlike banknotes which have separate issuers in Scotland and Northern Ireland, all UK coins are issued by the Royal Mint, which is an independent enterprise (wholly owned by the Treasury) which also mints coins for other countries.
In Britain's Crown Dependencies, the Manx pound, Jersey pound, and Guernsey pound are unregulated by the Bank of England and are issued independently. However, they are maintained at a fixed exchange rate by their respective governments, and Bank of England notes have been made legal tender on the islands, forming a sort of one-way de facto currency union. These currencies do not have ISO 4217 codes, so "GBP" is usually used to represent all of them; informal codes are used where the difference is important.
British Overseas Territories are responsible for the monetary policy of their own currencies (where they exist), and have their own ISO 4217 codes. The Falkland Islands pound, Gibraltar pound, and Saint Helena pound are set at a fixed 1:1 exchange rate with the British pound by local governments.
Legal tender and national issues.
Legal tender in the United Kingdom is defined such that "a debtor cannot successfully be sued for non-payment if he pays into court in legal tender." Parties can alternatively settle a debt by other means with mutual consent. Strictly speaking, it is necessary for the debtor to offer the exact amount due as there is no obligation for the other party to provide change.
Throughout the UK, £1 and £2 coins are legal tender for any amount, with the other coins being legal tender only for limited amounts. Bank of England notes are legal tender for any amount in England and Wales, but not in Scotland or Northern Ireland. (Bank of England 10/- and £1 notes were legal tender, as were Scottish banknotes, during World War II under the Currency (Defence) Act 1939, which was repealed on 1 January 1946.) Channel Islands and Isle of Man banknotes are legal tender only in their respective jurisdictions.
Bank of England, Scottish, Northern Irish, Channel Islands, Isle of Man, Gibraltar, and Falkland banknotes may be offered anywhere in the UK, although there is no obligation to accept them as a means of payment, and acceptance varies. For example, merchants in England generally accept Scottish and Northern Irish bills, but some unfamiliar with them may reject them. However, Scottish and Northern Irish bills both tend to be accepted in Scotland and Northern Ireland, respectively. Merchants in England generally do not accept Jersey, Guernsey, Isle of Man, Gibraltar, and Falkland notes but Isle of Man notes are generally accepted in Northern Ireland. Bank of England notes are generally accepted in the Falklands and Gibraltar, but for example, Scottish and Northern Irish notes are not. Since all of the bills are denominated in pounds sterling, banks will exchange them for locally issued bills at face value, though some in the UK have had trouble exchanging Falkland Islands pounds.
Commemorative £5 and 25p (crown) coins, and 6p coins made for traditional wedding ceremonies and Christmas gifts, rarely seen in circulation, are legal tender, as are the bullion coins issued by the Mint.
Value.
In 2006, the House of Commons Library published a research paper which included an index of prices in pounds for each year between 1750 and 2005, where 1974 was indexed at 100.
Regarding the period 1750–1914 the document states: "Although there was considerable year on year fluctuation in price levels prior to 1914 (reflecting the quality of the harvest, wars, etc.) there was not the long-term steady increase in prices associated with the period since 1945". It goes on to say that "Since 1945 prices have risen in every year with an aggregate rise of over 27 times".
The value of the index in 1751 was 5.1, increasing to a peak of 16.3 in 1813 before declining very soon after the end of the Napoleonic Wars to around 10.0 and remaining in the range 8.5–10.0 at the end of the 19th century. The index was 9.8 in 1914 and peaked at 25.3 in 1920, before declining to 15.8 in 1933 and 1934—prices were only about three times as high as they had been 180 years earlier.
Inflation has had a dramatic effect during and after World War II: the index was 20.2 in 1940, 33.0 in 1950, 49.1 in 1960, 73.1 in 1970, 263.7 in 1980, 497.5 in 1990, 671.8 in 2000 and 757.3 in 2005.
The following table shows the equivalent amount of goods and services that, in a particular year, could be purchased with £1.
The table shows that from 1971 to 2015 the British pound lost about 92 per cent of its buying power.
The smallest coin in 1971 was the p, worth about 6.4p in 2015 prices.
Exchange rate.
The pound is freely bought and sold on the foreign exchange markets around the world, and its value relative to other currencies therefore fluctuates.
Reserve.
Sterling is used as a reserve currency around the world. , it is ranked fourth in value held as reserves.
