What Iceland sells when it cannot sell electricity

How a country exports electricity it cannot ship

Iceland generates more electricity a head than any national grid was built to need, and 99.9% of it comes out of hydro and geothermal stations, with renewable sources covering about 85% of total primary energy as of the mid-2020s. None of that power leaves the island in the form it is generated. No submarine cable runs to mainland Europe, the feasibility of building one has been examined on and off for years, and Landsvirkjun, the national power company, has stated that exporting energy by sea cable or as electric fuel is off its current agenda.

So the electricity is exported in solid form. A smelter converts kilowatt hours into metal that fits in a ship's hold, and Iceland has run that trade since 1969, when the plant at Straumsvík near Hafnarfjörður started with a capacity of 33,000 tonnes a year. Three smelters now hold a combined capacity of over 850,000 tonnes a year as of 2019, which placed Iceland eleventh among aluminium-producing nations in 2023. In 2017 the export mix was 42% tourism, 17% seafood, 16% aluminium and 24% everything else.

The 2020s added a second converter working on the same principle. A data centre buys electricity, occupies very little ground and sends its output down a fibre. The International Monetary Fund's 2026 Article IV consultation found that investment in 2025 reflected a continued expansion of data centres, that the current account deficit widened to 3.6% of output that year partly on imports for them, and that the recovery projected for 2026 and 2027 is led by net trade in which rising data centre exports are one of three named components. An economy of 376,248 people, counted at the start of 2022, now has quarterly accounts that move on shipments of server components.

What the smelters turn the power into

All three plants are foreign-owned, and each was built around a supply of electricity rather than around a market. Rio Tinto Alcan's ISAL at Straumsvík has been expanded several times since 1969 and now runs at about 189,000 tonnes a year. Century Aluminum's Norðurál at Grundartangi started in 1998 and has been expanded to 260,000 tonnes; in 2012 it produced 280,000 tonnes worth 610 million dollars, or 76 billion krónur, and consumed 4,300 gigawatt hours doing it, close to a quarter of all the electricity the country generated that year. Alcoa's Fjarðaál near Reyðarfjörður opened in April 2008 with a capacity of 346,000 tonnes, and Landsvirkjun built the 690 MW Kárahnjúkar hydropower station to feed it, lifting installed national capacity from under 1,600 MW to around 2,300 MW.

Kárahnjúkar was the largest single act of industrial policy in Icelandic history and it was fought over. The World Wide Fund for Nature called on Alcoa to abandon the plant. The singer Björk opposed it early, and her mother, Hildur Rúna Hauksdóttir, went on hunger strike against it in 2002. Alcoa's own account of the project claimed no human displacement, no impact on endangered species and no danger to commercial fisheries. The company studied a second smelter near Húsavík between 2005 and 2011, to be powered by geothermal heat, and cancelled that Bakki project in October 2011.

Smelting is also why a country running on renewable power emits as much as it does. Icelanders emitted 16.9 tonnes of carbon dioxide per person in 2016, the highest figure among EFTA and EU members, mostly from transport and aluminium production, against a stated government goal of cutting greenhouse gas emissions by 40% by 2030 and reaching carbon neutrality by 2040.

Scale explains the rest of it. When an electrical equipment failure stopped work at Norðurál in October 2025, the value of national aluminium inventories fell by 5.4 billion krónur over the fourth quarter, against a fall of 797 million krónur in the same quarter of 2024, and Statistics Iceland named the fault in its national accounts release. One plant's switchgear is a line item in the country's books.

Why the data centres arrived when they did

Wholesale electricity in Iceland sat between 4 and 5 krónur per kilowatt hour until 2008. It climbed with demand towards 2019 and 2020, then climbed again from 2022 as data centres arrived while supply did not increase in step, which is the National Energy Authority's own reading of its price series. The authority expects a Nordic price of 9.5 to 12 krónur per kilowatt hour in 2030 and 5 to 7.5 by 2040, and expects domestic prices to rebalance between 2027 and 2030 once new generation is connected.

What the machines are doing with the power has changed. By the end of 2018 bitcoin mining was expected to consume more electricity than every resident of Iceland combined. Landsvirkjun now draws the line in writing, saying it intends to support digital development in data centres and not cryptocurrency mining.

The import side shows up quarter by quarter. Imports of computer components for data centres rose sharply in the fourth quarter of 2024 and through the first and second quarters of 2025, fell back in the third and were low in the fourth, and Statistics Iceland states that this materially shaped each quarter's capital formation. Business investment rose 7.5% across 2025 while output grew 1.3%, because much of the spending left again immediately as imports. The Central Bank's bulletin of August 2026 expects reduced marine product exports in 2026 to be offset by stronger export revenues from the data centre sector, which is the point at which the servers stop being an import and start being an export industry.

Why the grid has run out of headroom

Landsvirkjun's generating system is close to fully used. Annual consumption is around 21 terawatt hours, and the company expects demand to rise by 6.5 terawatt hours by 2035: roughly 4 for the energy transition, 1 for domestic growth and 1.5 for large users old and new. Meeting that means adding half a terawatt hour of generation every year. Between 2010 and 2020 Landsvirkjun commissioned three stations, Búðarháls, Búrfell II and Þeistareykir, which together produce about 2 terawatt hours, so the rate has been achieved before.

The obstacle is licensing rather than geology or capital. Landsvirkjun says construction at both Hvammsvirkjun and the Búrfellslundur wind farm could have begun two years earlier than it did, and that it has warned repeatedly that energy security for households and smaller firms could be volatile from 2024 to 2028 until new stations come online. Búrfellslundur is due to start generating in the last quarter of 2026 and Hvammsvirkjun in 2028, with the Þeistareykir extension finishing around the same time. The National Energy Authority puts it more bluntly still: new supply will not meet increased demand before 2027.

What has formed is a queue with a policy inside it. Landsvirkjun states that it will be unable to meet demand from new large users in the metal and raw material industries that would like to move operations to Iceland, which means the country is now choosing which industries get its electricity. The IMF's structural recommendations for 2026 open with reducing regulatory barriers and streamlining licensing and permitting. Iceland: politics takes up the machinery that issues those permits.

What the sea still pays for

Iceland's exclusive economic zone covers 758,000 square kilometres of water against 103,004 square kilometres of land, and the fleet landed close to 1.04 million tonnes in 2025, 4% more than in 2024. By volume that catch was 28% blue whiting, 21% cod, 17% herring, 13% mackerel and 8% haddock. By value the ranking inverts: cod alone was about 48% of the 1.15 billion euros of catch value in 2024, haddock about 12%, and demersal whitefish together roughly 60%.

The volume swings on a single stock. Capelin landings reached 450,000 tonnes in 2022 and 325,000 tonnes in 2023, the fishery closed in 2024, catches were around 6,000 tonnes in 2025, and the 2026 season is estimated at 152,000 tonnes. Total landings moved between 993,972 tonnes in 2024 and 1,418,021 tonnes in 2022 largely on that one fish. Quotas follow annual advice from the Marine and Freshwater Research Institute, reviewed against the International Council for the Exploration of the Sea, and are allocated as individual transferable quotas held as percentage shares of each stock.

Export value has moved in the opposite direction to volume. Seafood exports were worth 2.88 billion euros in 2025 from 608,000 tonnes, against 2.8 billion euros from 702,200 tonnes in 2022, which is less fish for more money. The European Union took 52% of the volume and 54% of the value in 2025, the United Kingdom 13 and 16%, and the United States about 5% of volume against over 10% of value, a premium market by unit price.

Aquaculture is the growth line underneath. Production rose from 5,050 tonnes in 2010 to 64,417 tonnes in 2025, an increase of 1,176% over the period, of which Atlantic salmon was 58,700 tonnes and Arctic char 5,100 tonnes in 2025. A new aquaculture bill before the Althing would set biosecurity zones by fjord, expand the framework to land-based and offshore farming, and allow production limits to be written as maximum biomass as well as annual output.

Employment is where the old economy still lives. Fishing and processing directly employ around 9,000 people, close to 5% of the workforce, while between 25,000 and 35,000, up to a fifth of everyone working, depend on the wider ocean cluster of gear makers, processors and marine biotechnology firms. Agriculture, forestry, fisheries and aquaculture together came to about 4.05% of output in 2024, and the sector that once provided nine tenths of export earnings in the 1960s now provides a small fraction of it.

How tourism became the biggest export earner

Tourism contributed 8.8% of output in 2025, a year in which Iceland received just under 2.3 million foreign overnight visitors. Services to foreign tourists rarely contributed more than 2% of output for most of the twentieth century, and the annual number of foreign visitors never exceeded 80,000 before the early 1980s. Arrivals then rose 378% between 2010 and 2018, and 2025 came in at 97.6% of that 2018 record.

The market has now flattened and started sorting itself. Departures through Keflavík in the twelve months to July 2026 totalled 2,250,066, down 1.7% on the twelve months before. American departures, 28.3% of the total at 636,052, fell 4.0%, while Chinese departures rose 21.9% to 134,271 and Chinese hotel nights rose 45.4% to 410,110. Icelanders' own hotel nights fell 19.9% to 555,948. Total guest nights in registered accommodation reached 9,922,496, up 2.4%, and the growth came from accommodation outside hotels and guesthouses, which rose 8.8%.

Seasonality is the structural weakness. Hotel room occupancy across the country was 89.8% in August 2025 and 43.0% in January 2026, and the average visitor stayed 6.8 nights in the year to July 2026. Concentration is the other one. Around 98.7% of visitors arrived through Keflavík in 2025, and many stay within an hour of it. Hotel rooms in Reykjavík rose 42% over a period in which visitor numbers rose 264%, short-term rentals absorbed the difference, and residential prices in the centre rose with them. In Akureyri, cruise arrivals rose 91% between 2015 and 2019 while local cafés recorded a 3.5% lift in trade during a ship's visit and restaurants 1%. About 322,000 cruise passengers reached the Port of Reykjavík in 2024, the highest figure recorded there.

The IMF's 2026 assessment names construction and tourism-related activity as the parts of the corporate sector that require vigilance, which is what a decade of building hotels against a curve that has stopped rising produces. Iceland: geography sets out the ground the visitors come for.

Why the króna sets the terms of everything

Iceland is the only country with a population under two million to run a floating exchange rate and an independent monetary policy. The Central Bank has issued the króna alone since 1961, and every shock a commodity economy of this size takes has passed through that currency. Inflation reached 43% in 1974 and 59% in 1980. The króna averaged 152 to the euro and 128 to the dollar in 2025.

The independence is being used hard at present. The Monetary Policy Committee raised the key rate to 8.00% on 19 August 2026, with inflation averaging 5.2% in the second quarter of that year and creeping to 5.3% in July while underlying inflation held near 4.2%. The Central Bank forecasts growth of 1.4% in 2026, 1.9% in 2027 and 2.6% in 2028, with inflation back at the 2.5% target in the first half of 2028. The IMF's numbers sit close: growth of 1.8% in 2026 and 2.1% in 2027, inflation averaging 5.2% and then 3.2%.

Wages are the transmission problem. The IMF found wage growth and inflation expectations elevated in 2026 despite a cooling labour market, warned of a de-anchoring of expectations and an erosion of export competitiveness, and recommended reforming wage-setting so that pay tracks productivity and the inflation target. Nominal wages rose 7.9% in 2025 against labour productivity growth of 1.9%. The review clause in the standing wage agreements was expected to be triggered at the end of August 2026.

Whether to keep the currency at all is a live question rather than a settled one. The IMF frames EU accession and euro adoption as political choices, trading deeper integration and possible gains in credibility against the loss of an independent monetary policy and exchange rate flexibility. A country whose exchange rate absorbed a banking collapse within living memory has reason to weigh the second half of that trade heavily.

What the collapse and the eruptions cost

Relative to the size of its economy, Iceland's banking failure in 2008 was the largest in recorded history. At the end of the second quarter of 2008 the assets of Kaupthing, Landsbanki and Glitnir came to 14.437 trillion krónur, more than eleven times national output, and external debt stood at 9.553 trillion krónur, around 50 billion euros, more than seven times the 2007 figure for output. At that scale the Central Bank could not act as a lender of last resort, and the knowledge that it could not was itself part of the run.

What followed set the terms for a decade. The government guaranteed domestic deposits, passed emergency legislation on 6 October 2008 that let the supervisor take over the banks, raised interest rates to 18% on 28 October, imposed capital controls in November, and secured 5.1 billion dollars from the IMF and the Nordic countries. Output fell 10% in real terms between the third quarter of 2007 and the third quarter of 2010, the stock exchange lost more than 90% of its market capitalisation, and the OMX Iceland 15 index was discontinued after a decade as the worst-performing index in the world. Iceland's placing on it fell sharply between 2007 and in 2010, and emigration to Norway rose from 293 people in 2005 to 1,625 in 2009.

The recovery ran on unusual terms. The economists Ásgeir Jónsson and Hersir Sigurjónsson recorded that Iceland was treated differently from earlier IMF clients, faced no call for sharp austerity at the start of the joint programme, was allowed large public deficits in 2009 so that fiscal multipliers could work against the contraction, and was never asked to shrink its Nordic welfare system. The programme ended on 31 August 2011, the loans were repaid by the end of 2015, and the capital controls imposed in November 2008 were lifted on 14 March 2017. The general government deficit fell from 9.7% of output in 2009 and 2010 to 0.2% in 2014.

The next shock came out of the ground rather than the balance sheet. A fissure eruption opened near Hagafell on 18 December 2023, lava destroyed three houses in the town of Grindavík in January 2024, and the state's purchase of houses there cost 1.2% of output, reclassified in the 2026 Article IV from below the line to above it because the future value of the properties is uncertain. Gross public debt was 56.1% of output in 2025 and is projected to reach 48.2% by 2031, and the IMF calls the economy's exposure to shocks the reason those targets are correctly ambitious. Twenty financial crashes since 1875, by one count, is the record a small open economy on a spreading volcanic ridge accumulates.
