Iran War Disrupts Hormuz Transit; Crude Flows Down 30% YoY as Tanker Routes Shift

The Iran war has triggered a seismic shift in global energy logistics. Flows of crude oil and petroleum products through the Strait of Hormuz fell by nearly 6 million barrels per day in the first quarter of 2026, a decline of approximately 30% year-over-year. Tanker routes have shifted; a Japanese supertanker recently made a rare, undercover transit through Hormuz, signaling that shippers are finding alternative paths and timing movements with extreme caution. The Panama Canal has benefited from diversified shipping, with revenues up on tanker rerouting. Simultaneously, a Chinese-owned supertanker is set to test the US naval blockade in the coming days, highlighting geopolitical tensions that keep shipping premiums elevated.

For crude and refined product prices, the supply disruption has created a structural premium. Brent and WTI both carryIncome earned from holding a position over time. a war-risk premium that will persist as long as Hormuz remains contested or unstable. This directly pressures fuel costs for airlines (Air New Zealand forecasted substantial full-year losses driven by elevated jet fuel), road transport, and energy-intensive industries. Import-dependent economies across Asia, particularly India and the Philippines, are depleting foreign-exchange reserves to defend their currencies and shield economies from the oil price shock. Pakistan's growth has accelerated, but the outlook is clouded by the Iran conflict and rising crude prices. Hunt Oil and other energy producers see the Middle East disruption as a nightmare scenario for lower production, while oil exploration and rare-earth mining become more strategic.

For equity markets, energy importers face margin compression (airlines, shipping, automotive, chemicals) while oil majors and independent explorers benefit from higher prices and potential supply-side consolidation.

For currency traders, the oil shock has accelerated reserve drawdowns in Asia, putting downward pressure on regional currencies (INR, PHP) relative to the USD.

The primary risk to sustained high oil prices is a swift cessation of hostilities or a diplomatic breakthrough that restores Hormuz traffic. Additionally, if global growth slows sharply (recession fears), demand destruction could quickly offset supply concerns. However, given the current stalemate in Iran tensions and the structural challenges of reopening Hormuz corridors, energy prices likely remain elevated for months.
