The Strait of Hormuz Has Collapsed — Here Is What 10-20 Ships a Day Means for the World

The Strait of Hormuz traffic has fallen from 150 ships a day to 10-20 ships a day. Here is the specific economic impact of this maritime collapse on food, fuel, and the global economy.

The Strait of Hormuz — the 39-kilometre-wide channel between Iran and Oman through which approximately 20 percent of global crude oil, 17 percent of LNG, and significant volumes of petrochemical and refined product trade normally transits — is now operating at approximately 10-20 vessels per day, down from the pre-war baseline of approximately 150 vessels per day. This reduction of approximately 90 percent is the specific economic shock that military conflict analysis had identified as the most significant single risk of a US-Iran military confrontation.

For the specific commodity impact: the World Bank warned on April 3 of 'mounting risks to inflation, jobs and food security worldwide.' Brent crude reached $109.03 per barrel — up approximately 45 percent from the $75 pre-war price. European natural gas TTF has risen approximately 60 percent. Fertiliser prices — whose primary feedstock is natural gas — have risen approximately 40 percent, creating the specific agricultural input cost crisis whose timing, as northern hemisphere spring planting begins, will affect the 2026 food supply chain.

For the global logistics dimension: the 90 percent traffic reduction means that approximately 135 vessels per day that would normally transit the strait are not transiting it. They are either holding in anchorages awaiting the conflict's resolution, rerouting around the Cape of Good Hope (adding approximately 14 days to Asia-Europe voyages), or cancelling voyages entirely. The specific insurance costs for vessels choosing to transit — war risk insurance whose current rates exceed $10 million per vessel per transit — have made most commercial transits economically untenable.

For the humanitarian impact: the specific populations whose food supply depends on the grain, fertiliser, and food commodity trade that transits the Strait of Hormuz are in the most acute risk category. Yemen, already experiencing food insecurity before the current conflict, is specifically vulnerable. East African nations whose LNG imports transit through regional hub ports that the strait feeds are experiencing specific energy access crises.

For the diplomatic dimension: the April 3 international meeting on Hormuz reopening — attended by representatives of the most affected nations — rejected Iranian attempts to impose tolls on transit (the specific diplomatic formulation Iran has proposed as a face-saving reopening mechanism) and discussed both diplomatic and military options for ensuring passage. No agreement was reached. The strait remains effectively closed.
