The Strait of Hormuz: The World's Most Critical Chokepoint
No body of water on earth carries more economic weight than the Strait of Hormuz. This narrow passage — measuring just 33 kilometres at its narrowest point between the Musandam Peninsula of Oman and Iran — is the jugular vein of global energy supply.
Before the outbreak of hostilities on February 28, 2026, approximately 20 million barrels per day (mb/d) of crude oil and refined petroleum products transited the Strait each year, according to the International Energy Agency (IEA). This represented roughly 27% of global maritime oil trade and nearly 20% of total world petroleum liquids consumption. The Strait also handles around a fifth of global liquefied natural gas (LNG) trade, with Qatar's Ras Laffan facility alone accounting for a dominant share of global LNG supply.
The critical asymmetry of the Strait is this: while Saudi Arabia and the UAE have pipeline capacity to bypass Hormuz for some flows — estimated at 3.5 to 5.5 mb/d combined — this represents barely a quarter of normal Strait throughput. Countries like Iraq, Kuwait, Qatar, Bahrain, and Iran itself rely almost entirely on the waterway. There is no viable alternative.
The IEA's head described the ensuing situation as "the greatest global energy security challenge in history" — a designation that underscores both the volume and velocity of the disruption.
How the War Unfolded: A Timeline of Energy Disruption
The 2026 Iran conflict began on February 28 with joint US-Israeli airstrikes targeting Iranian military infrastructure and leadership. Iran's retaliatory response rapidly escalated beyond Iran's borders, with missiles and drone strikes targeting Gulf infrastructure — oil terminals, refineries, data centers, and ports — as well as attacks on tankers transiting the Strait.
The International Energy Agency characterized the Hormuz disruption as "the largest supply disruption in the history of the global oil market" — surpassing the 1973 Arab oil embargo, the 1979 Iranian revolution, and the 1990 Gulf War in scale.
The Oil Price Shock: Data & Analysis
The price of Brent crude — the global benchmark — went from approximately $72 per barrel on February 27, 2026, to over $106 per barrel within days of the Strait's effective closure, a rise of more than 40% in under two weeks. At its peak, prices crossed $120/bbl following the formal Hormuz blockade on March 4.
Modelling by the Federal Reserve Bank of Dallas estimates that a closure removing close to 20% of global oil supplies in Q2 2026 would raise average WTI prices to $98 per barrel and lower global real GDP growth by an annualized 2.9 percentage points in that quarter alone. If the Strait reopened after one quarter, oil prices would fall back to around $68/bbl, but real GDP would remain 0.2% below pre-closure levels by year-end — and still 0.1% below by end of 2027.
Impact on the GCC Economies
The Gulf Cooperation Council — comprising Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain, and Oman — entered the 2026 crisis at a paradoxical moment. Non-oil GDP growth was accelerating. The IMF estimated non-oil GDP growth for the GCC averaging 3.7% in 2024 and 3.8% in 2025, well above rates in the US or Europe. Citi had projected overall GCC growth would accelerate from 4.3% in 2025 to 4.5% in 2026. That forecast has since been comprehensively overturned.

Saudi Arabia: The Kingdom Under Pressure
Saudi Arabia entered the crisis with a fiscal deficit of 5.3% of GDP in 2025, with capital spending being cut back. The kingdom had become increasingly reliant on external borrowing — reaching $156 billion — while net foreign assets of commercial banks showed a deficit of $57 billion at the end of January 2026. Saudi Arabia's East-West Pipeline can move up to 7 mb/d to the Red Sea port of Yanbu, bypassing Hormuz — but this covers only a fraction of lost export capacity. Foreign investors and lenders are reappraising Saudi risk, even if oil exports recover to pre-war levels within months.
Qatar: The LNG Powerhouse Goes Dark
Qatar suffered perhaps the most acute single blow of the early conflict: Iranian strikes targeted the Ras Laffan facility — the world's largest liquefaction complex — taking it offline as of March 2. QatarEnergy declared force majeure on all exports. This removed more than 2 billion cubic metres (bcm) of gas supply every week from global markets. QatarEnergy had already announced a delay to its flagship North Field East expansion project (33 mtpa, four-train), now pushed back from mid-2026 to end-2026 at the earliest.
UAE: Aviation, Tourism & Data Centers Disrupted
Dubai International Airport — which handled 95.2 million passengers in 2025 — faced closure and severe disruption. ADNOC's Ruwais refinery was hit by a drone strike. More unusually, Iranian strikes targeted Amazon data centers in the UAE and Bahrain — the first time any military had attacked commercial data centers in a conflict. Tourism bookings plummeted and business activity in Dubai and Abu Dhabi ground to a halt. A German economic analysis warned that a prolonged conflict would mean an economic "catastrophe" for both Qatar and the UAE.
Bahrain: The Most Vulnerable GCC State
Bahrain entered the war already among the most indebted countries in its peer group. The combination of the Hormuz crisis and Iranian drone attacks reduced its aluminum and oil exports — which together provide over two-thirds of government revenue. The country declared force majeure on operations through state energy firm Bapco.
| Country | Primary Vulnerability | Bypass Capacity | Fiscal Position | Severity |
|---|---|---|---|---|
| Saudi Arabia | Oil export revenue, Vision 2030 funding | ~7 mb/d via Yanbu pipeline | 5.3% deficit / GDP (2025) | High |
| Qatar | LNG exports (Ras Laffan offline) | None viable | Force majeure declared | Critical |
| UAE | Aviation, tourism, logistics, data centers | Limited ADCO pipeline | Ruwais refinery damaged | Critical |
| Bahrain | Aluminum & oil exports (67%+ of revenue) | None | Highly indebted; force majeure | Severe |
| Kuwait | Oil production; no pipeline bypass | None viable | Production cuts imposed | Critical |
| Iraq | 90% of GDP from oil; Basra fields hit | None | 70%+ production drop | Catastrophic |
| Oman | Export route; partial insulation | Some Gulf of Oman access | Partially insulated | Moderate |
The Global Economic Contagion
The World Economic Forum's analysis described the war's cascading economic fallout as "a structural shock to the world economy, delivered at a moment of geoeconomic fragility." The conflict arrived when global markets were already navigating tariff uncertainty, post-pandemic debt overhangs, and inflationary pressures that central banks had only recently begun to contain.
Asia Bears the Brunt
The asymmetry in the war's economic geography is sharp. The United States imports relatively little oil through Hormuz; its Asian allies and trading partners bear the overwhelming burden. Over 80% of oil and LNG shipped through the Strait in 2024 went to Asian markets — China, India, Japan, and South Korea being the primary destinations. Japan relies on the Middle East for ~90% of its crude oil imports, most transiting Hormuz. South Korea gets about 70% of its crude from the Middle East and routes more than 95% through Hormuz. In response, South Korea activated a 100 trillion won (~$68 billion) market-stabilization programme.
Europe: A Second Energy Crisis
Europe faced a second major energy crisis following its 2022 Russian gas shock. European gas storage entered the 2025–26 winter at historically low levels — estimated at just 30% capacity following a harsh season — leaving the continent with almost no buffer. The Dutch TTF gas benchmark nearly doubled to over €60/MWh by mid-March. The European Union raised its 2026 inflation forecast to between 2.6% and 4.4%, with UK inflation expected to breach 5% — the highest in Europe.
Inflation & Recession Fears
The OECD projected US inflation at 4.2% in 2026 — 1.2 percentage points above pre-war forecasts. IMF Managing Director Kristalina Georgieva warned in March that a prolonged conflict poses a significant inflationary risk globally. Capital Economics modelled that if the war extends for several months, eurozone GDP growth would slow to just 0.5% year-on-year in H2 2026, while Chinese economic growth could fall below 3% — a figure that would carry profound consequences for global demand.
UNCTAD warned that global merchandise trade growth would slow sharply from about 4.7% in 2025 to just 1.5–2.5% in 2026. The organization flagged that 3.4 billion people live in countries already spending more on debt than on health or education — populations for whom the additional energy and food price shocks carry acute humanitarian risk.
The LNG Crisis & Gas Markets
The disruption to global natural gas markets arrived at the worst possible moment. Gas markets had been gradually rebalancing following the 2022 Russian supply shock, but storage levels were depleted heading into early 2026. The suspension of Qatar's Ras Laffan facility — the world's largest LNG export terminal — removed over 2 billion cubic metres (bcm) of gas from global markets every week.
In 2025, almost 90% of LNG transiting the Strait of Hormuz was destined for Asian markets. This concentration means that countries like Japan, South Korea, and China faced simultaneous oil and gas supply crises. LNG prices in Asia surged, with Dutch TTF near doubling in Europe.
QatarEnergy had already announced a delay to its ambitious North Field East expansion — 33 mtpa, four-train — pushing it to end-2026 at the earliest. A six-to-twelve month delay would remove significant additional volumes precisely when global buyers had been counting on lower LNG prices for 2027–28. The conflict also raised questions about the future of the shared reservoir arrangement between Qatar and Iran.
The Center on Global Energy Policy at Columbia University noted that "core GCC producers had been unwinding OPEC+ production cuts throughout 2025, ramping up toward 16 mb/d — meaning a disruption now removes base supply, not just marginal barrels, creating a deeper physical deficit than if the conflict had occurred when production was artificially suppressed."
Food Security & Fertilizer Fallout
The Hormuz crisis is not merely an energy crisis — it is also an emerging food security crisis. The Gulf region is a major global supplier of fertilizers, and the disruption to these flows threatens to amplify the economic shock into agricultural systems worldwide.

fertilizer price spike
Iran, Saudi Arabia, Qatar, the UAE, and Bahrain together account for over a third of global urea supplies. The near-total halt of tanker traffic has caused severe sulfur shortages — with Gulf countries accounting for roughly 45% of global supply. The UN World Food Programme warned of long-term food price increases threatening a scenario similar to the 2022 global food crisis.
India offers a case study in cascading risk. It relies on the Gulf region for nearly 60% of petroleum imports, and over 40% of its urea and phosphate supply. Following the LNG output drop from Qatar, India reduced production at three urea plants. As a country accounting for approximately 25% of global rice exports, any reduction in Indian agricultural output ripples through global food supply chains.
The tech supply chain is also exposed: helium — crucial for semiconductor manufacturing — faces supply constraints as Gulf production is disrupted. Tungsten prices surged over 50% in March 2026 and have since more than tripled from December 2025 levels, as China restricted exports of the critical metal used in military applications, semiconductors, and precision manufacturing.
Three Scenarios: Short, Medium & Prolonged Conflict
Capital Economics and other leading macroeconomic forecasters have modelled three primary scenarios based on the duration of the conflict and the timeline for Hormuz reopening:
| Indicator | Pre-War Forecast | Short Conflict | Medium Conflict | Full Escalation |
|---|---|---|---|---|
| Brent Crude (end-2026) | ~$60/bbl | ~$65/bbl | ~$85–95/bbl | >$100/bbl |
| Global GDP growth | 3.1% | 2.8% | 1.5–2.0% | <1.0% |
| US Inflation (CPI) | 3.0% | 3.5% | 4.2% | 5.0%+ |
| Eurozone GDP growth | 1.2% | 0.9% | 0.5% | Contraction |
| China GDP growth | 4.8% | 4.2% | <3.0% | 1.5–2.0% |
| Global Merchandise Trade | 4.7% | 3.0% | 1.5–2.5% | Contraction |
| Global GDP at Risk (total) | — | $590B | $3.57T | $6.95T |
Who Wins, Who Loses: A Global Map of Winners & Losers
Not every economy suffers equally from the Gulf oil disruption. Some countries stand to gain — at least in the short term — from the price shock.
| Country / Region | Position | Key Dynamic |
|---|---|---|
| 🇷🇺 Russia | Beneficiary | Major non-Gulf hydrocarbon supplier; Russian stocks trending upwards; US eased sanctions on Russian oil to India during conflict |
| 🇺🇸 United States | Mixed | Shale production partially compensates; but inflation at 4.2%, gas prices hurt consumers; limited Hormuz exposure for imports |
| 🇧🇷🇨🇦🇦🇷 Americas Non-OPEC | Partial Beneficiary | Brazil, Canada, Argentina, Guyana benefit from higher prices; US LNG exporters benefit from Qatar LNG disruption |
| 🇯🇵 Japan | Major Loser | ~90% crude from Middle East; near-total Hormuz dependence; emergency energy measures activated |
| 🇰🇷 South Korea | Major Loser | ~70% ME crude, 95%+ via Hormuz; activated $68B market-stabilization programme |
| 🇨🇳 China | Major Loser | 50% of oil via Hormuz; GDP forecast below 3%; large strategic reserves deployed; simultaneously restricting tungsten exports |
| 🇮🇳 India | Major Loser | 60% petroleum from Gulf; 40%+ fertilizer from region; $125B remittances threatened; urea plant production cut |
| 🇪🇺 Europe | Significant Loser | Second major energy crisis; low gas storage; TTF nearly doubled; inflation 2.6–4.4% |
| 🌍 Global South | Acute Vulnerability | Debt crisis risk if North raises rates; Bangladesh, Pakistan, Vietnam severely affected fuel shortages; food prices rising |
Strategic Outlook & Long-Term Implications
The 2026 Iran war and the Hormuz disruption will leave lasting structural marks on the global energy system — regardless of how quickly hostilities end. Several long-term implications are already taking shape:
1. Accelerated Energy Diversification
The crisis is accelerating what analysts had long theorized: a structural push to reduce reliance on the Hormuz corridor. Expect expanded investments in US LNG export terminals, North African pipelines, East African gas development, and expanded pipeline capacity from Central Asia. Saudi Arabia is reportedly considering expanding its East-West pipeline beyond its current 7 mb/d capacity, citing the same fears first raised during the 1980s Iran-Iraq "tanker war."
2. The AI-Energy Infrastructure Paradox
The war exposed an underappreciated vulnerability: Iranian drone strikes on Amazon data centers in the UAE and Bahrain — the first military targeting of commercial data centers in history. The Gulf states, especially the UAE, have invested heavily in AI infrastructure as a post-oil economic foundation. The strikes demonstrate that concentrating the world's most valuable AI infrastructure in one of its most geopolitically volatile regions carries profound economic and strategic risk.
3. Food System Stress as a Lasting Legacy
Even a short conflict will leave agricultural markets destabilized for a planting-season cycle or more. Fertilizer supply disruptions take months to propagate through to farmgate prices, and then months more to appear in food prices. The WFP and IFPRI warn that the worst food security impacts may not peak until late 2026 or into 2027 — long after any ceasefire.
4. Geopolitical Realignment
The war has exposed a fundamental contradiction: the US has imposed enormous costs on some of the same economies it relies on as strategic and trading partners — Japan, South Korea, India, and Europe. This will complicate post-conflict coalition politics and deepen calls in Asia for alternative energy sourcing and financial architectures not dependent on US-secured sea lanes.
5. The GCC's Dual Challenge
Gulf states face a paradox: higher oil prices offer some revenue compensation, but the war is simultaneously damaging the very infrastructure, foreign investor confidence, and diversified economic pillars (aviation, tourism, logistics, AI) that they spent decades building as alternatives to oil dependency. The non-oil growth story that had defined GCC ambition through 2025 has been severely interrupted — and rebuilding investor trust will take years.
What is clear is that the Strait of Hormuz has reasserted itself — with brutal force — as the world's most consequential maritime chokepoint. The question is no longer whether the global energy system needs to hedge against Hormuz risk. The question is how quickly and at what cost it can do so.
