- Iran’s Hormuz blockade has created a 10% global oil supply deficit, per Oxford Economics — already forcing factory cutbacks in India, fertilizer plant closures in Bangladesh, and per-fill limits at gas stations in Indonesia and Australia
- Europe is next: gasoline prices are up 15% and diesel up 30% across the EU, natural gas has jumped more than 50%, and the EU energy commissioner has called demand reduction “necessary” as reserves get drawn down
- Ryanair’s CEO has warned of potential jet-fuel shortfalls by May; JPMorgan analysts say U.S. West Coast disruptions — particularly in California, where gas has hit nearly $6 a gallon — could materialize on the same timeline
- Pakistan has raised gasoline prices 46% and diesel prices nearly 90% since the war began, with its petroleum minister warning the country must act to “avoid a default-like situation” — illustrating the existential risk the oil shock poses to emerging market economies
What Happened?
The oil shock triggered by the Iran war and Hormuz blockade is advancing in waves across the global economy — first hitting Asia and now threatening Europe and parts of Africa. Oxford Economics estimates the strait’s closure has left global oil supply 10% below pre-war needs. Asia, geographically closer to the Gulf, felt the impact first: India has cut liquefied petroleum gas allocations to factories — including steel, auto, and textile manufacturers — to 70% of pre-war levels; Bangladesh has shut most natural gas-based fertilizer plants; Indonesia has capped motorist fuel purchases at 50 liters per day; and Australia has begun publishing weekly national fuel stock reports, with some stations already reporting dry pumps and others limiting per-fill volumes. Meanwhile, Europe — which holds roughly 450 million barrels in reserve according to Societe Generale — entered the crisis with larger buffers than Asia but is now drawing those reserves down rapidly. Gasoline is up 15% and diesel up 30% across the EU; natural gas has surged more than 50%. Slovenia has imposed per-fill limits after panic buying and cross-border “fuel tourism” depleted stations in border regions.
Why It Matters?
The geographic sequencing of the oil shock — Asia first, then Europe, then potentially the U.S. West Coast — provides a rough playbook for what comes next, but it also obscures how quickly conditions can deteriorate when reserves run low. Most countries are currently cushioning consumers from the full price shock through fuel tax cuts, subsidies, or cash handouts — Morgan Stanley estimates domestic fuel prices in Asia have risen only 16% even as spot prices are up 53%. That gap is economically unsustainable, and poorer countries are already breaking: Pakistan has passed through almost the full price shock and its petroleum minister is openly discussing default risk. The EU energy commissioner’s call for demand reduction is significant — it signals that European governments have shifted from hoping the war ends quickly to managing for a prolonged supply constraint. For global companies with European operations, energy-intensive industries (aviation, chemicals, steel, ceramics) face a material margin squeeze that will show up in Q2 earnings.
What’s Next?
Even if Trump’s stated two-to-three week timeline for winding down U.S. operations in Iran proves accurate, an end to the fighting would not immediately reopen the strait — Iran’s gatekeeping infrastructure remains in place, and diplomatic negotiations over the terms of reopening would take additional time. Ryanair’s CEO has warned the aviation industry faces jet-fuel shortfalls by May, and JPMorgan analysts flag potential disruptions on the U.S. West Coast — particularly California, where gas has already reached nearly $6 a gallon — on a similar timeline. The critical variable is the pace at which diplomatic talks produce a ceasefire framework with explicit Hormuz reopening conditions. Every week of continued closure deepens the supply deficit, expands the number of countries forced into emergency rationing, and raises the political cost of a prolonged war. For investors, the Iran war’s economic impact is no longer a geopolitical tail risk — it is an active constraint on global growth, and the longer it persists, the harder it will be to contain.
