Kuwait and the 1990–91 Gulf War: Occupation, Oil Fires and Recovery

Most wars in this book are long. The occupation of Kuwait lasted seven months. Yet it is one of the clearest examples in modern history of a war aimed directly at an economy’s main asset. Iraq’s invasion was about oil, debt and territory. Its retreat ended with hundreds of burning oil wells. Kuwait’s output fell by more than half in two years, then rebounded as fast as it had fallen. The war also created two unusual economic institutions. One was a system of burden sharing in which allies paid most of the cost of a US-led war. The other was a UN fund that, over three decades, took a share of Iraq’s oil revenue and paid it out as compensation. This chapter looks at all three: the collapse, the recovery and the bill.

1. Background: how the war began

On 2 August 1990 Iraq invaded and occupied Kuwait.^[8] Kuwait was a small, very rich oil state. Its overseas investments were estimated by the Financial Times at more than $100bn in early 1990.^[18] This chapter focuses on the economic effects of the invasion rather than the political dispute that led to it.

The invasion took two large oil exporters out of the world market. The US government’s 1991 Economic Report of the President says lost Iraqi and Kuwaiti exports amounted to about 4.3 million barrels a day. The oil price jumped.^[11] A US-led coalition assembled in Saudi Arabia. Coalition air strikes began on 16 January 1991. On the same day Iraqi forces began setting Kuwait’s oil wells on fire, starting at the Wafra field.^[8] The ground offensive began on 24 February, and Kuwait City was liberated on 28 February 1991.^[8]

The economic story did not end there. Kuwait had to put out the fires, rebuild the oil industry, bring back its population and pay its share of the war’s cost. Iraq was required to pay compensation from its oil revenue through a UN body, the United Nations Compensation Commission (UNCC), set up as part of the UN Security Council in 1991.^[15]

2. Where things stand now

The war is long over, and its financial bill has been settled. As of October 2026, the UNCC has closed. It received about 2.7 million claims, asking for a total of $352.5bn, and awarded $52.4bn to about 1.5 million successful claimants.^[16][14] The last payment, $629,324,488, went to the Government of Kuwait on 13 January 2022.^[14] The UN Security Council ended the Commission’s mandate in February 2022, and it formally closed on 31 December 2022.^[15]

Kuwait’s economy recovered fully from the 1990–91 war long ago. In 2025, the IMF estimates, it grew by 2.7%, with inflation of 2.4% and a general government surplus of 24.5% of GDP (this measure counts investment income from Kuwait’s sovereign wealth).^[21] However, the Gulf faced a new shock in 2026. Because of the Iran war and disruption to shipping through the Strait of Hormuz, discussed in another chapter of this book, the IMF’s October 2026 data project that Kuwait’s real GDP will shrink by 16.7% in 2026, before rebounding by 17.1% in 2027.^[21] The IMF expects Kuwait’s surplus to narrow to 15.8% of GDP in 2026 and government debt to rise from 14.6% to 26.6% of GDP.^[21] So, as of October 2026, Kuwait is again dealing with a war-related collapse in oil exports. This time it is caused by a blocked shipping route, not by occupation. The lessons of 1990–91 are therefore not only history.

3. The economy before the war

Oil and investment income. Before 1990 Kuwait was one of the richest economies in the world per person. GDP per person, in constant 2015 dollars, was about $20,700 in 1989.^[6] The economy depended on oil, but it also had a second source of income: returns on overseas investments. In 1987, according to the US Library of Congress, foreign investments earned about $6.3bn while oil earned about $5.4bn.^[18] In other words, investment income was larger than oil income that year.

Saving for the future. In 1976 Kuwait set up the Reserve Fund for Future Generations with an initial $7bn, and decided to put 10% of its revenues into it each year.^[18] This is an early example of a sovereign wealth fund: a state-owned fund that invests national savings, often from natural resources, for the long term.

A volatile oil economy. Even before the war, growth swung sharply with oil output and prices. Real GDP fell by 10.1% in 1988 and grew by 25.9% in 1989.^[1] GDP in current dollars was about $24.3bn in 1989.^[2] Exports of goods and services were about $12.7bn that year.^[5] Inflation was low, at 3.3%.^[4]

A population of migrants. In 1989 Kuwait had about 2.2 million residents.^[3] A large share were migrants. A 1991 US Congressional workshop heard that about 300,000 Jordanians and Palestinians returned home from Kuwait as a result of the crisis.^[20] This matters because when the population changes so much, output per person and total output can move in very different ways.

4. The economic impact: indicator by indicator

4.1 Output and GDP

The fall in output was enormous. According to the World Bank, Kuwait’s real GDP fell by 26.2% in 1990 and by 41.0% in 1991.^[1] Together this means output in 1991 was less than half its 1989 level. In current dollars, GDP fell from about $24.3bn in 1989 to about $18.4bn in 1990 and about $11.0bn in 1991.^[2]

The recovery was just as dramatic. Real GDP grew by 82.8% in 1992 and 34.0% in 1993.^[1] By 1993 nominal GDP was back to about $23.9bn, close to the 1989 level.^[2] The IMF’s historical series shows almost the same pattern, though it puts 1993 growth slightly higher, at 35.1%.^[21]

Why was the recovery so fast? Kuwait’s main asset, its oil in the ground, was damaged but not destroyed. Once the fires were out and wells, gathering centres and refineries were repaired, oil could flow again. This is very different from a war that destroys factories, skills and institutions.

4.2 Oil output and the oil fires

The oil fires were the most visible economic damage. A US Department of Defense report on the fires says Iraq ignited or damaged more than 750 of Kuwait’s 943 wells. It uses 605 burning wells as its standard figure, and notes that estimates of the number on fire range from 605 to 732.^[8] A 2016 Kuwait Times report on the anniversary of the end of the fires put the number set on fire at about 700.^[10] (The figures differ because they count different things: wells burning, wells damaged and wells gushing oil without burning.)

At the peak, about 4–6 million barrels of crude oil and 70–100 million cubic metres of natural gas burned every day. By November 1991 more than 1 billion barrels of crude had been lost.^[8] Before the war, the industry’s experts had expected a worst case of 100 to 125 wells destroyed. The actual damage was seven to eight times greater.^[9]

Firefighting began in March 1991. At first four North American companies did the work. By September 1991 there were 27 teams, and more than 10,000 workers from 37 countries were involved.^[9] The rate of capping rose from about 3 wells a day in May to about 8 a day in October. The last well was capped on 6 November 1991, about eight months after the work began.^[9][10] Kuwait spent an estimated $1.5bn on firefighting alone and more than $5bn on rehabilitating the oil industry.^[9] A speaker at the 1991 Congressional workshop estimated the income lost to the fires at about $87m a day.^[20]

Oil production data show the scale of the collapse and recovery. Measured in energy terms, Kuwait’s oil output fell from about 796 terawatt-hours (TWh) in 1989 to 544 TWh in 1990 and only 107 TWh in 1991, a fall of about 87% from 1989. Output recovered to 628 TWh in 1992 and 1,123 TWh in 1993.^[7]

4.3 Trade and the balance of payments

With oil exports stopped, trade collapsed. Exports of goods and services fell from about $12.7bn in 1989 to about $8.3bn in 1990 and about $1.9bn in 1991. They recovered to about $8.0bn in 1992 and $11.4bn in 1993.^[5] For an economy built on oil exports, this meant almost no export earnings for more than a year.

4.4 Public finances, reserves and the war bill

During the occupation the Kuwaiti government was in exile. With oil revenue gone, the government and its citizens relied on investment income and on sales of overseas investments. This money paid for living costs in exile, Kuwait’s contribution to coalition costs, and post-war reconstruction and repair of the oil industry.^[18] A speaker at the 1991 Congressional workshop said Kuwait was selling large amounts of debt assets and borrowing against US-held securities.^[20] We could not find a reliable published figure for exactly how much of Kuwait’s foreign assets were used up, so this chapter does not give one.

The bill was large. Kuwait paid about $16.1bn towards US costs, almost all of it in cash.^[13] Early estimates of the cost of rebuilding were also large: about $40bn to restore basic services according to a report in February 1991, and between $40bn and $100bn for infrastructure according to another estimate presented to the US Congress.^[19][20] The US Department of Defense report on the fires gives a conservative estimate of $30–50bn for the total economic cost of the occupation to Kuwait.^[9] These figures are estimates from different sources and use different methods, so they should be treated as a range, not a precise number.

4.5 Inflation and the currency

Inflation rose during the crisis but stayed moderate. Consumer prices rose by 9.8% in 1990 and 9.1% in 1991, up from 3.3% in 1989. Prices then fell slightly, by 0.6%, in 1992, and rose by only 0.4% in 1993.^[4] Part of the reason inflation stayed under control is that Kuwait could pay for imports from its foreign assets even when oil exports stopped. A country without such reserves would probably have seen its currency collapse.

4.6 Population and the labour market

The war caused a sharp fall in population. The World Bank’s data show about 2.22 million residents in 1989, 1.68 million in 1990 and 1.35 million in 1991. Population recovered to about 1.63 million in 1992 but was still only about 1.73 million in 1996.^[3] The departure of about 300,000 Jordanians and Palestinians is one reason the population did not return to its pre-war level for years.^[20]

This change in population matters for the data. GDP per person in constant 2015 dollars fell from about $20,700 in 1989 to about $14,800 in 1991, then rose to about $29,300 in 1993, well above the pre-war level.^[6] Part of this jump comes from higher oil output in 1993 and part from a smaller population. It does not mean that every resident was better off.

4.7 Special indicator: the world oil market

The invasion was also a global supply shock. The spot price of oil was about $17 a barrel in June 1990 and almost $21 at the end of July. It reached about $28 on 6 August and about $40 in mid-October 1990.^[11] Other producers, including Saudi Arabia, Venezuela, the UAE and the US, raised output enough to fully offset the 4.3 million barrels a day lost from Iraq and Kuwait.^[11] After Desert Storm began in mid-January 1991, the spot price fell back to about $20, close to its pre-invasion level.^[11]

Some producers gained. A speaker at the 1991 Congressional workshop estimated Saudi Arabia’s oil windfall in 1990 at $14–16bn, while also noting that Saudi Arabia spent about $4bn resettling Kuwaiti citizens.^[20] For oil importers, the shock was costly. The Economic Report of the President estimated that a 50% oil price rise lasting a year would cut real GNP growth by about 1–1.5 percentage points, raise unemployment by about 0.5 points and temporarily raise inflation by 1.5–2.5 points.^[11]

4.8 Special indicator: who paid for the war

The Gulf War is unusual because allies paid most of its cost. The US Office of Management and Budget estimated the US incremental cost at $61.1bn. The US General Accounting Office (GAO) reported that, by September 1991, foreign governments had pledged $48.3bn in cash and paid $42.4bn, plus about $5.8bn of in-kind help such as fuel.^[12] A final accounting put total foreign contributions at about $54.1bn, which left the US paying about $7bn itself, according to PolitiFact’s review of the official records.^[13] Kuwait’s share was about $16.1bn.^[13]

4.9 Special indicator: compensation and the costs to Iraq

The UNCC was funded by a share of Iraq’s oil export revenue. The share was originally 30%, and was later cut to 3% in 2017.^[16] In 2000, the UNCC awarded Kuwait Petroleum Corporation $14.7bn for lost oil production and sales.^[17] In total, $52.4bn was paid to about 1.5 million claimants, including individuals, companies and governments.^[14] For Kuwait, this was a large transfer of resources over three decades. For Iraq, it was a deduction from the export revenue of a country that was itself damaged by war and sanctions. The scheme is the most important modern example of war reparations paid through a multilateral body.

4.10 Environmental costs

The fires produced a huge smoke plume that damaged regional air quality and released potentially harmful gases and particles.^[8] More than 1 billion barrels of oil were lost.^[8] The UNCC created a follow-up programme for its environmental awards, including awards to Kuwait, to monitor how the money was used for environmental clean-up.^[16] From an economic point of view, environmental damage is a negative externality: a cost borne by people who were not party to the decision, and which is not reflected in market prices.

5. What went well and what went wrong

What went well (from an economic-policy perspective)

• Saving for a rainy day paid off. Overseas assets of more than $100bn allowed Kuwait to keep paying for imports, living costs in exile and reconstruction without its oil income.^[18]
• Firefighting was faster than many expected. All wells were capped by 6 November 1991, about eight months after work began.^[9][10]
• Output recovered quickly: real GDP grew by 82.8% in 1992 and 34.0% in 1993.^[1]
• Inflation stayed moderate, at about 9–10% in 1990–91, and fell to almost zero in 1992–93.^[4]
• Other oil producers fully replaced lost Iraqi and Kuwaiti exports, so the global price spike was short.^[11]
• The UNCC paid out all $52.4bn of its awards before closing.^[14][15]

What went wrong

• Output collapsed: real GDP fell by more than half between 1989 and 1991.^[1]
• Oil worth billions was lost: more than 1 billion barrels burned or spilled.^[8]
• Damage was far worse than planned for: seven to eight times the pre-war worst case.^[9]
• The population fell by about 40% between 1989 and 1991 and recovered only slowly.^[3]
• Kuwait had to spend heavily: about $16.1bn for coalition costs, $1.5bn on firefighting and over $5bn on oil industry repairs.^[13][9]
• Compensation took more than 30 years to complete.^[14]
• The fires caused environmental and health costs that markets did not price.^[8]

6. The economics behind it

A supply shock to a single-commodity economy. For Kuwait, the war was mainly a negative supply shock. The productive capacity of the oil sector was cut almost to zero in 1991. In a PPC diagram, the curve shifts sharply inward. Because the oil itself remained underground, the shift was temporary: once wells were repaired, the PPC moved back out.

A global AS shock. For the world economy, losing about 4.3 million barrels a day of exports was a negative supply shock. In an AD/AS diagram, the SRAS curve shifts left, raising prices and cutting output: a mild form of stagflation. The 1990 shock was short because other producers had spare capacity and raised output.^[11]

Sovereign wealth as self-insurance. Kuwait’s foreign assets worked like an insurance policy. When income stopped, the country could run down its assets instead of cutting consumption or imports. This is an example of consumption smoothing: using savings to keep spending stable when income falls.

Burden sharing and public goods. Restoring Kuwait and protecting Gulf oil supplies benefited many countries, including those that did not fight. This has features of a public good: it is hard to exclude anyone from the benefits. Public goods create a free-rider problem, because each country would prefer others to pay. The Gulf War’s burden-sharing deals, in which allies paid about $54bn of a $61bn cost, were a way of overcoming that problem.^[13][12]

Reparations. Making the aggressor pay for damage is an old idea in war economics. A standard concern is that very heavy reparations can weaken the paying economy and, through lower trade and instability, its neighbours. The UNCC tried to limit this risk by taking a share of Iraq’s oil revenue rather than a fixed sum, and by cutting the share from 30% to 3% over time.^[16]

7. Outlook and the way forward

The direct economic legacy of 1990–91 has been settled: the fires are long out, oil output recovered by 1993 and the compensation process closed in 2022.^[7][15] The lessons, however, are relevant to Kuwait’s position in October 2026.

• Concentration risk. In 1990–91 and again in 2026, Kuwait’s dependence on oil exports through one route made it very vulnerable to war. The IMF projects a 16.7% fall in real GDP in 2026.^[21] Diversifying the economy and export routes is the long-term answer.
• Buffers matter. In both crises, large financial reserves allowed the state to keep spending. The IMF still expects a fiscal surplus in 2026, though a smaller one.^[21]
• Recovery path. If the 1991–93 experience is a guide, an oil economy can recover very quickly once the physical barrier is removed. The IMF projects growth of 17.1% in 2027.^[21] Recovery depends on how fast export routes reopen, not on rebuilding a damaged state.
• Risks. A long disruption could use up more savings and raise government debt, which the IMF expects to rise to 26.6% of GDP in 2026.^[21]

8. Exam-style questions

Glossary

• Burden sharing: an agreement in which allies share the cost of a joint military operation.
• Consumption smoothing: using savings or borrowing to keep spending stable when income changes.
• Free-rider problem: when people or countries benefit from a good without paying for it, so too little is provided.
• Incremental cost: the extra cost of an operation above what would have been spent anyway.
• Negative externality: a cost imposed on third parties that is not reflected in market prices.
• Price-inelastic demand: demand that changes little when price changes, so supply shocks cause large price changes.
• Public good: a good that is non-excludable and non-rival, such as security of a shared resource.
• Reparations: payments made by a state to compensate for damage caused by war.
• Sovereign wealth fund: a state-owned fund that invests national savings for the long term.
• Spot price: the price for immediate delivery of a commodity.
• Stagflation: rising prices and falling or stagnant output at the same time.
• Supply shock: a sudden event that changes the economy’s ability to produce.
