TLDR
- Tehran announced complete closure of the Strait of Hormuz following renewed U.S. military operations
- Brent crude climbed to $93-$94 per barrel range, with WTI hovering between $89-$91
- American petroleum reserves declined by 7.2 million barrels last week, significantly exceeding forecasts
- Energy analysts at Rystad predict potential $150 per barrel spike should comprehensive military engagement occur
- Likelihood of imminent diplomatic resolution between Washington and Tehran has diminished from roughly 40% to highly uncertain
Military exchanges between Washington and Tehran this week have triggered a sharp rise in petroleum prices and intensified concerns about energy security across the Middle East region.
Tehran announced a complete blockade of the Strait of Hormuz, prohibiting passage for all maritime traffic, including petroleum tankers and commercial shipping. Iranian officials issued warnings that any vessel attempting passage through the strategic waterway would face military action.
The Strait of Hormuz represents one of the planet’s most vital energy transit points. A substantial portion of internationally traded crude oil passes through this narrow waterway daily.
Brent crude reached the $93 to $94 per barrel level. West Texas Intermediate traded in the $89 to $91 per barrel range. Both benchmark contracts experienced gains exceeding 2% during early Asian market hours before moderating somewhat.

President Trump stated Wednesday that Washington would strike Iran “very hard” should diplomatic efforts collapse. American military forces subsequently conducted additional strikes against Iranian installations during overnight operations.
Tehran reported launching retaliatory strikes targeting American military installations in Kuwait and Bahrain. The preceding wave of U.S. operations followed Iran’s downing of an American Army Apache helicopter in proximity to the Strait of Hormuz.
Trump also disclosed that American military forces had been covertly protecting petroleum shipments transiting the strait. He indicated that over 100 million barrels had successfully moved through the waterway under U.S. military escort.
Diplomatic Prospects Diminish as Military Actions Intensify
Jorge Leon, an energy analyst with Rystad Energy, noted it remains premature to determine whether current military escalation represents a complete breakdown or a serious yet containable incident.
Leon indicated the probability of achieving a near-term diplomatic agreement has dropped from approximately 40% several weeks ago to a far more uncertain outlook. He emphasized the coming days would prove decisive.
John Oh, an analyst at Commonwealth Bank, stated that Iran’s actions within the 12-hour period following American strikes would receive intense scrutiny. He suggested any significant retaliation would undermine market assumptions regarding an imminent agreement.
Analysts from ING stated in their assessment that energy shipments from the Persian Gulf region would continue facing severe disruptions. They noted that diplomatic resolution still appears considerably distant.
Petroleum Inventories Already Declining
Data released by the U.S. Energy Information Administration revealed crude inventories decreased by 7.2 million barrels during the week concluding June 5. Market analysts had anticipated a drawdown of approximately 3 million barrels.
Gasoline reserves registered a modest increase. Distillate stocks, encompassing diesel fuel and heating oil, declined by 0.2 million barrels.
Rystad’s Leon cautioned that should Washington and Tehran enter comprehensive military hostilities, oil prices could surge to $150 per barrel. He projected price fluctuations would remain elevated until definitive evidence emerges that a ceasefire can be maintained.
American consumer inflation reached 4.2% in May, intensifying worries that elevated energy expenses could prolong higher interest rate conditions. Financial markets monitored U.S. producer price figures and weekly unemployment claims for additional insight into Federal Reserve monetary policy direction.
