The economy history of Iceland covers the development of its economy from the Settlement of Iceland in the late 9th century until the present.

The field of economic history in Iceland According to a 2011 review study by economic historian Guðmundur Jónsson, Economic history as an independent field of study is of fairly recent origin in Iceland, emerging only in the last quarter of the twentieth century with the increased specialisation and differentiation of the history profession. With no separate economic history departments and in fact, only one general university, the University of Iceland in Reykjavík, it is not surprising that economic history has largely been in the hands of either historians educated within the broad church of history, non-professionals or scholars outside the history profession. Only in the last twenty years or so have specialist economic historians, educated abroad, entered the field and turned the subject into a distinct discipline.

Pre-18th century economic history Trade in medieval Iceland was conducted through barter.

According to the traditional nationalist historical narrative, which has been associated with historian Jón Jónsson Aðils (1869–1920), Iceland experienced a golden age from 874 (settlement) to the 11th century (this period has often been referred to as the Saga Age). This period of prosperity purportedly ended when Iceland fell under foreign rule (Jónsson 1903, 79, 88–89, 103, 105, 178). Under foreign rule, the Icelandic nation declined and ultimately suffered humiliation (Jónsson 1903, 241-242). Aðils' lessons were that under Icelandic rule, the nation was prosperous, productive and artistic, but suffered under foreign role. However, Aðils argued that within every Icelander, a desire for freedom and nationalism remained, and only had to be awoken. Historian Guðmundur Hálfdanarson suggests that Aðils himself was doing his best to awaken this slumbering nationalist sentiment and strengthen the Icelandic pursuit of independence.

According to Icelandic historian Axel Kristinsson, there is little historical evidence to substantiate the aforementioned traditional narrative about economic decline after the Saga age. The Icelandic historian Árni Daníel Júlíusson characterizes the period 1550-1800 as a golden age in Icelandic farming. However, a 2009 book by the Icelandic historian Gunnar Karlsson supports the decline thesis, as he shows a 40% reduction in GDP from the 12th century to the 18th century. The Danish anthropologist Kirsten Hastrup characterizes the period 1400-1800 as a "period of remarkable social disintegration and technological decline."

18th to 20th century Iceland had among the lowest GDP per capita in Western Europe at the start of the 20th century. According to one assessment by Central Bank of Iceland economists, Post-World War II economic growth has been both significantly higher and more volatile than in other OECD countries. The average annual growth rate of GDP from 1945 to 2007 was about 4%. Studies have shown that the Icelandic business cycle has been largely independent of the business cycle in other industrialised countries. This can be explained by the natural resource-based export sector and external supply shocks. However, the volatility of growth declined markedly towards the end of the century, which may be attributed to the rising share of the services sector, diversifi cation of exports, more solid economic policies, and increased participation in the global economy.According to Reuters, Iceland has had "over 20 financial crises since 1875".

Agricultural modernization Certain institutional arrangements in Iceland retarded the modernization of agriculture and the growth of non-agrarian sectors. One such institution was "the system of land tenures with its heavy obligations to landlords and insecure farm leases, which discouraged fixed capital investment on the farms. The other was a wide-ranging social legislation set up to regulate family formations and to maintain a balance between agriculture and the fishing sector in favour of the former. The most effective regulatory device was a stringent labour bondage which had few parallels in Europe."

In the early 20th century, there was a decline in rowing boat fishing as the fishing industry moved towards mechanized fishing vessels.

Prior to 1880, agriculture (in particular, sheep products) was the largest share of Icelandic exports.

Urbanization According to University of Iceland economists Davíd F. Björnsson and Gylfi Zoega, "The policies of the colonial masters in Copenhagen delayed urbanisation. The Danish king maintained a monopoly in trade with Iceland from 1602 until 1855, which made the price of fish artificially low – the price of fish was higher in Britain – and artificially raised the price of agricultural products. Instead, Denmark bought the fish caught from Iceland at below world market prices. Although the trade monopoly ended in 1787, Icelanders could not trade freely with other countries until 1855. Following trade liberalisation, there was a substantial increase in fish exports to Britain, which led to an increase in the number of sailing ships, introduced for the first time in 1780. The growth of the fishing industry then created demand for capital, and in 1885 Parliament created the first state bank (Landsbanki). In 1905 came the first motorised fishing vessel, which marked an important step in the development of a specialised fishing industry in Iceland. Iceland exported fresh fish to Britain and salted cod to southern Europe, with Portugal an important export market. Fishing replaced agriculture as the country's main industry. These developments set the stage for the urbanisation that was to follow in the twentieth century."

Food consumption A 1998 study found that food consumption patterns differed from those in the rest of Europe: "The prominence of domestically produced dairy products, fish, meat and suet, and the insignificance of cereals until the nineteenth century, are among the most unusual features."

Growth of the fisheries sector After 1880, fish products were the largest share of Icelandic exports. The fisheries sector in Iceland grew in part due to expanded fishing with sailing smacks. With the mechanization of the fishing fleet, which began primarily in 1905, fishing became an overwhelmingly large part of the Icelandic economy.

World War I In the quarter of a century preceding the War, Iceland prospered. Iceland became more isolated during World War I and suffered a significant decline in living standards. The treasury became highly indebted, there was a shortage of food and fears over an imminent famine.

Iceland traded significantly with the United Kingdom during the War, as Iceland found itself within its sphere of influence. In their attempts to stop the Icelanders from trading with the Germans indirectly, the British imposed costly and time-consuming constraints on Icelandic exports going to the Nordic countries.

The War led to major government interference in the marketplace that would last until the post-World War II period.

The Great Depression Icelandic post-World War I prosperity came to an end with the outbreak of the Great Depression, a severe worldwide economic depression. The Depression hit Iceland hard as the value of exports plummeted. The total value of Icelandic exports fell from 74 million kronur in 1929 to 48 million in 1932, and was not to rise again to the pre-1930 level until after 1939. Government interference in the economy increased: "Imports were regulated, trade with foreign currency was monopolized by state-owned banks, and loan capital was largely distributed by state-regulated funds". Due to the outbreak of the Spanish Civil War, which cut Iceland's exports of saltfish by half, the Depression lasted in Iceland until the outbreak of World War II when prices for fish exports soared.

World War II The British and American occupations of Iceland caused an end to unemployment, and contributed to the end of the Great Depression in Iceland. The occupiers injected money into the Icelandic economy and launched various projects. This eradicated unemployment in Iceland and raised wages considerably. According to one study, "by the end of World War II, Iceland had been transformed from one of Europe's poorest countries to one of the world's wealthiest."

1945–1960 Iceland remained relatively protectionist during the period 1945–1960, despite its participation in the OEEC's Trade Liberalisation Program (TLP). Economic historian Guðmundur Jónsson attributes Icelandic protectionism in the post-WWI period to the "external shock caused by the war, creating an artificial economy internally and the overvaluation of the krona, made adjustment to peacetime circumstances extremely difficult. The task was made harder by a public policy prioritizing on growth and investment rather than balanced macroeconomic management. Last but not least, Iceland's commercial interests were not easily reconcilable with those of the other members of the OEEC because of her special pattern of trade."

In the period 1945–1960, the United States provided extensive economic assistance to Iceland. Iceland received the largest Marshall Aid package per capita in the period 1948-1951 (even though Iceland was left relatively unscathed from World War II), almost twice as much as the second highest recipient. Later in the 1950s, Iceland received direct economic assistance from the United States in what University of Iceland historian Valur Ingimundarson has referred to as the equivalent of a "second Marshall aid" package.

From 1951 to 2006, the Iceland Defense Force provided between 2% and 5% of Iceland's GDP.

1980s The Icelandic economy was in an upswing in the mid-1980s. In 1987, the tax rates were temporarily reduced to zero.

1990s In 1991, the Independence Party, led by Davíð Oddsson, formed a coalition government with the Social Democrats. This government set in motion market liberalisation policies, privatising a number of small and large companies. At the same time economic stability increased and previously chronic inflation was drastically reduced. In 1995, the Independence Party formed a coalition government with the Progressive Party. This government continued with the free-market policies, privatising two commercial banks and the state-owned telecom Síminn. Corporate incomes tax was reduced to 18% (from around 50% at the beginning of the decade), inheritance tax was greatly reduced and the net wealth tax abolished. "Nordic Tiger" was a term used to refer to the period of economic prosperity in Iceland that began in the post-Cold-War 1990s.Global freeze kills Nordic tiger , The Age, 11 October 2008.

The welfare state The social expenditure as a percentage of GDP in Iceland lagged considerably behind the social expenditures in the other Nordic states during the 20th century. There are two primary reasons in the academic literature for why Iceland lagged behind: "The absence of a strong social democratic party" - Whereas labor unions were fairly strong in Iceland, votes on the left were split between several leftist parties, which meant that the leftist tendencies did not translate into political power. "A stronger emphasis on individualism and self-help"
