The 2026 Iran war, including the closure of the Strait of Hormuz, has led to what the International Energy Agency has characterized as the "largest supply disruption in the history of the global oil market". The conflict has echoed the 1970s energy crisis through acute supply shortages, currency volatility, inflation and heightened risks of stagflation and recession. A 2026 market analysis by MCB Group placed the current disruption alongside four earlier oil-market shocks, noting that in each case the initial price spike proved larger than the eventual sustained increase. The 1990–91 Gulf War saw oil prices decline within about nine months of the initial spike, according to a survey of historical oil shocks. A similar pattern followed the 2003 Iraq War. The Congressional Research Service found that oil prices, after rising sharply at the outset of the conflict, returned to pre-crisis levels within a few months. Brent crude's rise to nearly $130 a barrel after Russia's 2022 invasion of Ukraine but fell back over the following months. MCB Group similarly noted that a $10–15 per barrel risk premium associated with the June 2025 Twelve-Day War between Israel and Iran dissipated within days after the ceasefire.

As the result of the crisis, interest rate reductions were expected to be postponed or conversely increased in light of higher inflation caused by supply shortages and speculation. Stock markets experienced declines globally and there was a global bonds market sell-off. Nevertheless, since the S&P 500 hit 6,316.91 points on March 30, 2026, it increased 17.3% closing at 7,411.98 points on July 24, 2026.

Nevertheless, as tension eased, brent prices fell from a pick of $118.35 in March 31, 2026 to $71.57 in July 01, 2026. As tension in the gulf started to increase the brent price increased to $100.69 in July 23, but in July 24, despite mounting threats by U.S president Donald Trump, the brent price closed at $96.78. Moreover, oil shipping index which picked to 3,737 in March 2026 has declined to 1,850 in July 2026.

Background

The 2026 Iran conflict began on 28 February, with joint US–Israeli airstrikes targeting Iranian leadership and military infrastructure, including a decapitation strike that assassinated Supreme Leader Ali Khamenei. The operation, codenamed "Operation Epic Fury" by the US, involved advanced military equipment costing millions of dollars, such as precision-guided munitions and stealth aircraft. Iran retaliated with missile and drone strikes on US and Israeli targets, as well as Gulf states hosting US forces, leading to airspace closures and attacks on infrastructure. Prior to the conflict, Iran's economy was strained by sanctions, protests, and a depreciating rial, with inflation exceeding 40% in 2025. The strikes intensified these pressures, while global markets reacted to fears of supply chain disruptions.

Moreover, some economists have argued that modern economies are less vulnerable to oil shocks that in the 1970s, citing lower oil intensity, more flexible labor markets, and more credible monetary policy. A similar pattern has been found using geopolitical risk indices more broadly. On July, the IMF revised its world GDP growth rate to 3% for 2026 and 3.4% in 2027. The forecasted growth rate is higher than the actual growth rates in 2023–2025. According to IMF the effect of the oil supply shock on the world economy is limited since the AI-driven demand offsets the negative effect of the oil supply shock. Moreover, according to the WSJ July 2026 survey of 74 economists, the consensus remains that the U.S. economy will avoid a recession, with the average probability of a downturn over the next year falling to 25% from 33% in the previous survey.

Arab states of the Persian Gulf as well as Iran itself rely on the Strait of Hormuz for their energy exports and grocery imports, with only Saudi Arabia and UAE having alternative, albeit limited, routes. The war has caused a systemic collapse of the Gulf Cooperation Council economic model. Following the closure of the Strait of Hormuz on 4 March 2026, oil and LNG exports were stranded, causing Brent Crude to surge past $120 per barrel and forcing QatarEnergy to declare force majeure on all exports.The oil production of Kuwait, Iraq, Saudi Arabia, and the United Arab Emirates collectively dropped by a reported 6.7 million barrels per day by 10 March, and by at least 10million barrels per day as of 12 March. The maritime blockade triggered a concurrent "grocery supply emergency" across Gulf Cooperation Council states, which rely on the Strait for over 80% of their caloric intake; by mid-March, 70% of the region's food imports were disrupted, forcing retailers like Lulu Retail to airlift staples, resulting in a 40–120% spike in consumer prices. The crisis has shifted from a fiscal contraction toward fears about a humanitarian crisis following Iranian strikes on desalination plants—the source of 99% of drinking water in Kuwait and Qatar. The regional aviation sector, including Emirates and Qatar Airways, faced a near-total cessation of operations due to multi-national airspace closures, causing widespread disruption to global air travel. A United Nations Development Programme study released on 30March estimated that the war could reduce economic growth in Arab nations by in GDP.

Beyond immediate trade disruptions, analysts have noted a profound shift in the region's long-term economic narrative. Deutsche Welle reported that the Gulf states are unlikely to sustain high levels of investment spending during or after the war. The conflict has been described as the "end of the narrative" that the Gulf is a permanently safe destination for expatriates, immigrants, and tourists; the Qatar-funded Middle East Council on Global Affairs suggested the war has "irreversibly shaken" the region's image, exposing a deep-seated fragility beneath the facade of the Gulf's rapid economic transformation. Sinem Cengiz, a Kuwaiti journalist, conveyed in her article how the immeasurable social and psychological impact in the economic, political and security spheres were unlikely to fade.

The war has precipitated a second major energy crisis and subsequently economic crisis for Europe, primarily through the suspension of Qatari liquefied natural gas (LNG) and the closure of the Strait of Hormuz. The conflict coincided with historically low European gas storage levels—estimated at just 30% capacity following a harsh 2025–2026 winter—causing Dutch TTF gas benchmarks to nearly double to over €60/MWh by mid-March. Consequently, the European Central Bank (ECB) postponed its planned interest rate reductions on 19 March, raising its 2026 inflation forecast and cutting GDP growth projections, with economists warning that energy-intensive economies face high risks of technical recession if the maritime blockade persists through the summer refill season. The crisis has further impacted industrial output in the United Kingdom and the EU, where chemical and steel manufacturers have imposed surcharges of up to 30% to offset surging electricity and feedstock costs, potentially leading to permanent deindustrialization in some sectors. The economic impact on Europe has been characterized by a severe energy-supply shock and industrial strain, with the European Central Bank (ECB) warning that a prolonged conflict will likely trigger a period of stagflation, a period of low growth rates accompanied by inflation, and push major energy-dependent economies, including Germany and Italy, into technical recession by the end of 2026. British company Shell had issued a warning that Europe could face a shortage of fuel as early as April.

The rest of the world has been affected by panic buying and severe disruption to the distribution of petroleum, much of which is sourced from the Middle East and transits the Strait of Hormuz, the latter blockaded by Iran in early March 2026. The Philippines declared a state of emergency on the 24th March due to a concurrent strike by transport workers, while other countries such as Zimbabwe, Pakistan, Bangladesh, Nigeria, and Vietnam face similar predicaments with severe shortages of fuel. However other countries such as Australia and India have more sufficient reserves but face challenges with panic buying and their "crisis is almost entirely man-made". Economies most reliant on the strait for energy imports are in Asia, with Europe also viewing the strait as vital for its energy security. The initial disruption of petroleum is expected to affect Asia the most, but Europe is likely to be hit hard in the medium-to-long term.

Due to related increased tensions in Houthi Yemen, commercial vessels have been avoiding the Bab-el-Mandeb strait and the Suez Canal route in preference to the Cape of Good Hope to reach the Indian Ocean. The official entry of the Houthis into the war on 28 March has raised fears of disruption to global shipping and consequent supply shortages. Additionally, the simultaneous war between Afghanistan and Pakistan has disrupted airspace and trade routes through Central Asia.

Global

Energy markets

The head of the International Energy Agency described the situation caused by the war as the "greatest global energy security challenge in history". The conflict caused immediate volatility in energy markets, with Brent crude oil prices surging 10–13% to around $80–82 per barrel by 2 March 2026. Iran's closure of the Strait of Hormuz disrupted 20% of global oil supplies and significant liquefied natural gas (LNG) volumes. Exports from the region are typically going to Asian countries, with China, India, Japan and South Korea accounting for 75% of oil and 59% of LNG exports. However, Singapore and Taiwan depend more on Qatari LNG, while Pakistan and Bangladesh are more price sensitive.

QatarEnergy later announced that it was declaring force majeure on its contracts with buyers, and internal sources, according to Reuters, said that it would soon be shutting down gas liquefication as LNG tankers could not leave the Gulf, and that restarting it would take weeks. These announcements caused increases in world gas prices, which analysts said was a part of the Iranian government's plan to apply pressure on the world to stop the war. On 6 March, al-Kaabi warned that if the war continues other Gulf energy producers may be forced to halt exports and declare Force Majeure, and that "this will bring down economies of the world".

On 6 March, it was reported that according to satellite imagery analysis by both Bloomberg and the Energy Economics and Society Research Institute in Tokyo, Ras Laffan, the main gas facility in Qatar, appears to have not been damaged before the "unprecedented shutdown" which sent fuel prices higher. The United States, buffered by domestic production, faced less direct impact but saw gasoline prices rise 5–10 cents per gallon daily. The British think tank The Food Policy Institute has warned of long-term increases in food prices due to disruption in fuel and fertilizer markets.

On March 18, Iran hit Qatar's inactive Ras Laffan Industrial City LNG complex, causing a 17% reduction in Qatar's LNG production capacity. The damages from this attack were estimated to require 3–5 years to fully repair. Consequently, LNG spot prices in Asia increased by over 140 %.

The blockade of the Strait of Hormuz, the route of approximately 20% of the seaborne crude oil and LNG exports, keeps energy supply tight.

By 28 March, analysts feared that another hard oil crisis would unfold that was expected to be very decisive to the global economy. Three days later oil prices hit US$4 per gallon, as the war with Iran caused a surge of 30% in gas prices.
