How the disruption of oil, liquefied natural gas, and urea exports will cascade through the world economyLarry C. Johnson March 10, 2026
Oil: The Immediate ShockThe abrupt closure of Persian Gulf oil exports will constitute the largest supply shock in the history of petroleum markets larger in absolute terms than the 1973 Arab oil embargo or the Iranian Revolution of 1979, both of which removed far smaller volumes, if Iran maintains the blockade for a month or longer. The International Energy Agency estimates that OECD strategic reserves could theoretically cushion a disruption for several months, but the psychological and speculative impact on oil prices would be immediate and severe.
Analysts and historical precedent suggest that oil prices could spike to anywhere between $150 and $250 per barrel or potentially higher if markets judged the disruption likely to be prolonged. At such prices, the consequences would radiate rapidly through the global economy:
Fuel costs and consumer prices. Petrol, diesel, aviation fuel, and heating oil prices have all surged. In major consuming economies the United States, Europe, China, Japan, India consumer price inflation will accelerate sharply with a prolonged disruption. Households will face dramatically higher energy bills and transport costs within weeks.
Industrial contraction. Energy-intensive manufacturing sectors petrochemicals, cement, steel, aluminium, glass will face crippling input cost increases. Many would reduce output or shut down. Supply chains across the global economy would seize as freight costs soared.
Aviation and shipping. Aviation fuel costs would make large swaths of commercial aviation economically unviable. Shipping freight rates, already elevated by fuel costs, would compound broader supply chain disruption.
Recession risk. Every major oil price shock since the 1970s has been followed by a global economic recession. A shock of this magnitude would almost certainly do the same. The IMF and World Bank have historically estimated that a $10 per barrel sustained rise in oil prices reduces global GDP growth by around 0.20.5 percentage points; a shock ten or twenty times larger would be categorically different in nature.
Here are the most vulnerable countries to this shock:
JapanJapan is the world's most structurally vulnerable major economy to a Gulf oil shock. It imports approximately 90% of its crude oil from the Middle East, with Saudi Arabia, the UAE, Kuwait, and Qatar as its dominant suppliers. Japan has almost no domestic oil production, very limited alternative import infrastructure, and a dense industrial base dependent on petroleum. Its strategic reserves among the largest in the world at around 150 days of consumption provide a buffer, but not immunity. A prolonged closure lasting more than six months would force severe rationing, industrial curtailment, and recession. Japan's post-***ushima decision to phase down nuclear power has deepened its vulnerability by reducing the one energy source that could partly substitute.
South KoreaSouth Korea imports over 70% of its crude from the Middle East, with the Gulf states as its largest suppliers. Like Japan, it has negligible domestic production. Its economy is heavily industrial semiconductors, shipbuilding, petrochemicals, and steel all energy-intensive sectors that would face rapid input cost crises. South Korea maintains strategic reserves of approximately 100 days. Its proximity to Japan means both nations would compete for limited alternative supply from West Africa, North America, and Russia, driving prices higher still.
IndiaIndia is the world's third-largest oil importer and sources roughly 6065% of its crude from the Gulf region, primarily Iraq, Saudi Arabia, and the UAE. It has limited domestic production and strategic reserves of only around 1015 days among the smallest relative to import volume of any major economy. India's fuel subsidy architecture means the government would face enormous fiscal pressure as global oil prices surged, at the same moment that import costs were consuming foreign exchange reserves. For India's 1.4 billion population many of whom have limited financial buffers the pass-through of energy and food cost increases would be devastating. India's industrial heartland, its agricultural sector (which depends heavily on diesel for irrigation pumps), and its nascent manufacturing base would all be severely disrupted.
TaiwanTaiwan imports almost all of its energy requirements and sources a significant majority of its oil from the Gulf. As the world's primary producer of advanced semiconductors, a disruption to Taiwan's energy supply would carry consequences far beyond its own economy threatening global technology supply chains. Taiwan's strategic reserves are modest, and alternative supply routes would be expensive and slow to establish.
Pakistan and BangladeshBoth nations are heavily dependent on Gulf oil imports and have almost no strategic reserves, limited foreign exchange, and large populations with high fuel and food price sensitivity. Pakistan in particular has endured recurring foreign exchange crises; a surge in import costs would likely trigger a balance-of-payments collapse. For Bangladesh, fuel price increases would threaten the cost competitiveness of its garment sector the backbone of its export economy as well as the diesel-powered irrigation that supports its rice production.
Sub-Saharan Africa (Particularly Kenya, Ethiopia, Tanzania)Many sub-Saharan African nations depend on Gulf oil for a large majority of their refined product imports, with minimal domestic refining capacity and no strategic stockpiles. Countries like Kenya, Ethiopia, and Tanzania would face acute fuel shortages, with knock-on effects on transport, electricity generation, and agricultural supply chains. Governments with limited foreign reserves would be unable to sustain imports at elevated prices for any prolonged period.

Urea exposure:
ConclusionThe Persian Gulf is not merely an important trade route it is a structural dependency baked into the global economy over seven decades. The simultaneous disruption of oil, LNG, and urea flows from the region constitute a polycrisis of exceptional severity: an energy shock, an industrial shock, and a food security crisis arriving together, reinforcing one another, and challenging the capacity of governments, international institutions, and markets to respond.
Decades of optimisation around cost efficiency concentrating energy production, fertiliser manufacture, and shipping in the most economical locations has created a system that is efficient in stable conditions but catastrophically fragile under stress. If Iran is able to sustain the closure of the Strait of Hormuz for a month or more, it will enjoy significant leverage in negotiations to end the blockade."
