Strait of Hormuz Oil Flows Plunge as Ceasefire Collapses, War Reignites
Oil shipments through the Strait of Hormuz have fallen sharply in recent days, dropping back toward their lowest war-time levels after briefly recovering. A temporary ceasefire and peace agreement signed on June 17 had allowed flows to recover to roughly 50-60 percent of pre-war levels, bringing relief to global energy markets. But when fighting resumed in early July, President Trump declared the peace deal over. Oil flows have now fallen to 3 to 5 million barrels per day, creating a shortage of roughly 13.4 million barrels daily in the Persian Gulf region. Brent crude prices have jumped above 84 dollars per barrel, up more than eight percent in five days. The uncertainty threatens further economic disruption as the strait—which carried 25 percent of the world's oil before the war—remains unstable. Global refineries are operating at reduced capacity, and shipping through the waterway faces high insurance costs and the risk of naval mines.
Key facts
- Oil flows through the Strait of Hormuz fell to 3-5 million barrels per day as of July 15, 2026, down from 50-60% of pre-war levels before ceasefire collapsed
- The June 17 Memorandum of Understanding between the U.S. and Iran provided a 60-day ceasefire but collapsed after renewed fighting on July 7-8
- Before the February 2026 war started, the strait carried 25 million barrels of oil per day, roughly 20% of global petroleum consumption
- Brent crude jumped to $84 per barrel, up 8% in five days, after fighting resumed

How different outlets framed it
Left-leaning coverage: Progressive outlets highlight the humanitarian toll and argue that aggressive U.S.-Israeli military action triggered the escalation. They emphasize the need for diplomatic solutions and warn that sustained military intervention will only deepen regional instability and damage global economies that depend on affordable energy.
Right-leaning coverage: Right-leaning outlets like Breitbart argue Iran bears responsibility for the crisis through its attacks on shipping and threats to the strait. They emphasize the need for strong U.S. military deterrence and support the Trump administration's willingness to use force to protect American energy interests and global freedom of navigation.
Limits of this briefing
The situation remains fluid and volatile, with reports of renewed strikes and counter-strikes daily. Limited access to Iranian government statements and military operational details means some claims lack independent verification from both sides.
