Summary

Story summary

Iran and Oman have blocked the Strait of Hormuz, halting a key oil-LNG route.
The strait previously moved about one quarter of global crude oil and one fifth of LNG.
The blockade has triggered acute shortages of oil, gas, fertilizer and naphtha.
Asian economies report the hardest impacts on farming, cooking and medical imaging.
IMF director Krishna Srinivasan says the shortages are forcing industry cuts, job losses and slower growth.

History

Historical Context

The 1973 OAPEC oil embargo—triggered by the Yom Kippur War and announced in October 1973—cut output by 5 % each month, slashing Middle-East exports by up to 70 % and driving world prices from $3 to $12 per barrel by 1974. Today Iran and Oman’s closure of the Strait of Hormuz echoes that weaponization, prompting IMF warnings of supply shocks.
