Iran’s IRGC Claims Sea Mines Struck Three Tankers in Strait of Hormuz

A very large crude carrier is adrift and on fire after allegedly striking a naval explosive at the mouth of the Strait of Hormuz on Friday. The IRGC Navy said the supertanker, which was transporting more than 2M barrels of crude, was the third oil ship to encounter mines in the strategic waterway in a single day because the vessels utilized restricted shipping lanes and disabled tracking systems.

U.S. Central Command (CENTCOM) rejected a separate Iranian claim that its navy destroyed a U.S. military sea drone, stating that all its unmanned surface vessels in the region are accounted for. While Tehran attributes the recent tanker fires to sea mines, the U.K. Maritime Trade Operations center and Reuters identified the cause of one incident involving the Panama flagged Louise 1 as limpet mines attached to the hull by a small boat.

87%est.−7.5%
Strait of Hormuz intermittent restricted throughput
Restricted Hormuz throughput creates a stagflation shock: the broad equity market falls 7%, erasing $6.72T over 20 days as energy, freight and financing costs rise while growth weakens. Energy gains 3.7%, but Consumer Cyclicals lose 9.5% and Technology loses 8.8%, because producers benefit from scarcity while energy users and growth-sensitive assets absorb higher costs and lower valuations.
Consumer Cyclicals −9.5% · Technology −8.8% · Industrials −7.8%
13%est.−12.8%
Strait of Hormuz commercial energy transit cessation
A near-total halt in Strait of Hormuz energy traffic produces a stagflationary shock: the broad equity market falls 12%, erasing $11.5 trillion over 20 days. Expensive energy, freight and financing punish technology and consumer-sensitive businesses, while energy gains 5.3% as higher oil and LNG realizations outweigh the wider selloff.
2%est.+4.3%
Sustained Strait of Hormuz commercial-transit normalization without political settlement
Sustained Hormuz transit normalization lifts the broad equity market 4%, adding $3.84T as cheaper energy, shipping and credit support risk appetite. Energy loses pricing support, while technology and fuel-importing utilities benefit from lower costs and easier financial conditions.
Consumer Cyclicals +5.3% · Technology +5.2% · Non-Energy Materials +4.4%
