US-Iran Conflict Triggers Unprecedented Global Energy Crisis: Strait of Hormuz and Bab al-Mandeb Blockades, Damietta Drone Strike Explained

Bab al-Mandeb: The Houthis declared a naval blockade of this southern Red Sea gateway on July 21, 2026, threatening to attack tankers using Saudi ports . Iran has signaled it could use Houthi allies to close this chokepoint as well, creating a dual blockade . The Red Sea had become a critical alternative route for Persian Gulf states’ energy exports following the Iranian closure of the Strait of Hormuz . At least seven oil tankers have altered their courses in the Red Sea following the Houthi warnings .

Suez Canal threat: Major shippers (Maersk, Hapag-Lloyd, CMA CGM) suspended Suez transits starting March 2026 . The Suez Canal has seen traffic decline by about 50% since the war began, according to reports . The July 29 drone strike at nearby Damietta port demonstrated the canal's vulnerability to the widening conflict .

The Damietta Drone Strike

On July 29, 2026, a drone struck a US-owned LNG storage tanker (FSRU Energos Winter) at Egypt's Damietta Port, spreading fire to the LNG tanker GasLog Salem and causing significant damage . Egypt's cabinet confirmed the attack was caused by a drone, though no party claimed responsibility . It was the first such attack on Egyptian soil since the war began . The attack on the Egyptian port near the Suez Canal demonstrated the important waterway’s vulnerability and showed how the widening conflict in the Middle East could further disrupt global trade, analysts said .

Chevron CEO Warning: 'Fragile' Energy Markets

Chevron CEO Mike Wirth has been among the most vocal industry leaders warning of the crisis:

• On August 2, 2026, he said the Iran war has left energy markets "somewhat fragile and uncertain" and warned of "very real" threats to global oil supplies .
• He previously stated that physical oil shortages are beginning to appear globally due to the Hormuz closure, that "the buffers and shock absorbers are being steadily drawn down," and that July–August 2026 are critical months for oil inventories .
• In May 2026, Wirth stated, "We will start to see physical shortages" and indicated that economies, particularly in Asia, would begin to contract as demand adjusts to the diminished supply .
• Oil inventories have been drawn down around the world, including both strategic stocks and commercial stocks . ExxonMobil executives also warned that oil prices could skyrocket as oil stockpiles continue draining .

Market Impact and Rerouting

With roughly 20% of the world's oil passing through Hormuz blocked and the Red Sea route also threatened, oil tankers are diverting around Africa, adding significant costs and voyage time .

• The US has conducted 11 rounds of airstrikes on Iran and proposed charging a 20% fee for Strait of Hormuz transit security .
• The dual chokehold on Hormuz and Bab al-Mandeb represents an unprecedented simultaneous threat to the two most critical energy maritime corridors in the world .
• Analysts warned that if Iranian proxies close the Bab el-Mandeb strait, it could potentially drive oil prices up to $150 a barrel .
• The US military has deployed over 20 US Navy warships and hundreds of military aircraft across the Middle East .

Bottom line: The US-Iran conflict has produced the most severe simultaneous blockage of global oil shipping chokepoints in decades — Hormuz closed since late February, Bab al-Mandeb blockaded since July 21, and the Suez Canal effectively shut to major container lines — with the Damietta drone strike on July 29 confirming the war is now reaching into Egypt. Chevron's CEO has publicly warned that physical oil shortages are emerging and global inventories are dangerously low.
