The Iran conflict is reshaping energy markets and supply chains in real time. Satellite imagery and trade data show that Iranian oil export capacity has been severely curtailed, with Kharg Island's export jetties repeatedly empty. Saudi Arabia reported to OPEC that its own crude production collapsed to the lowest level since 1990 in April, as the broader regional turmoil crimped shipping and refining activity. A Chinese-owned supertanker hauling Iraqi crude through the Persian Gulf is being monitored as it attempts to exit the Strait of Hormuz, testing the effective US blockade on Iranian energy exports.

Supply-chain firms are accelerating safety stockpiling to protect against further disruptions, with reports of inventory buildup at the highest levels since the 2022 post-pandemic crisis.

Fitch Ratings downgraded Bangladesh's outlook to negative, citing high vulnerability to Middle East energy supply disruptions. Conversely, energy exporters benefit from elevated prices, though their own inflation also rises. The UK faces challenges to its economic recovery as sterling trades vulnerably and gilt yields rise on inflation fears.
