Strait of Hormuz Oil Shipments Surge to Post-Ceasefire High as Middle East Waterway Reopens

The Quick Take

• Crude shipments through the Strait of Hormuz surged to their highest level since the U.S.-Israeli conflict with Iran began in February
• A ceasefire deal reopened the strategic waterway, alleviating oil supply fears that had pushed Brent and WTI premiums higher
• The reopening reduces geopolitical risk premium in oil prices but raises questions about ceasefire durability and future Hormuz access

Crude oil shipments through the Strait of Hormuz climbed to their highest weekly volume since hostilities between U.S.-Israeli forces and Iran began in February, as a ceasefire agreement reopened the critical waterway to normal transit. The Strait of Hormuz carries approximately 20% of global oil supply and 30% of global liquefied natural gas, making any restriction on its access an immediate catalyst for global energy price increases. The ceasefire-driven reopening in the UAE's reporting window provided relief to oil markets that had been trading with an elevated geopolitical risk premium for several months.

The market implications of restored Hormuz flow are significant across the oil and gas supply chain. Gulf Cooperation Council exporters including Saudi Arabia, the UAE, Kuwait, and Iraq now have unobstructed export routes for their crude output, reducing the discount those producers had been forced to offer to buyers concerned about delivery risk. International oil companies with Middle East exposure see improved operational certainty. LNG tankers servicing Qatar's export terminals, which also transit the Strait, benefit from the same reopening. Shipping insurers and war-risk premium underwriters will likely reprice coverage lower in the near term.

Investors in energy markets should monitor the durability of the ceasefire and whether any resumption of hostilities could re-close the Strait. OPEC+ production decisions will be the next key catalyst, as restored Hormuz access removes the production disruption premium that may have previously justified keeping output constrained. The macro variable governing oil prices through the rest of 2026 is the interplay between restored Hormuz supply and global demand growth: if the Strait remains fully open while demand softens on Fed rate-hike headwinds, Brent could fall toward the high $60s; sustained demand and a secure Hormuz would support prices above $80.
