Brent Surges Past $90 as U.S. Strikes Iran and Threatens Kharg Island

Key points

• Brent crude futures closed at $90.49 per barrel, up 2.7%, while WTI settled at $85.76, up 2.8%, following renewed U.S.-Iran hostilities.
• U.S. Central Command confirmed strikes on two Iranian rocket launchers on Larak Island, with Iran reporting casualties and retaliatory attacks on U.S. bases in Jordan.
• President Trump warned that Iran’s Kharg Island oil export terminal would be 'blown to smithereens,' heightening fears of supply disruption.
• Tanker traffic in the Strait of Hormuz remains at a fraction of pre-war levels, with daily oil flows averaging 6 million barrels, well below historical norms.
• Diesel supplies are tightening further as Russia extends an export ban through the end of the month and Middle East refinery damage persists.

Background

This escalation follows a volatile summer of U.S.-Iran tensions. In July, oil briefly topped $100 during a 13-day strike campaign, followed by a brief pause in August when Trump halted planned strikes amid diplomatic efforts. The current flare-up marks a return to direct combat after a lull, with the conflict now in its sixth month, significantly disrupting global energy logistics and refining capacity.

How outlets are covering it

CNBC and OilPrice.com both emphasize the immediate price impact and the threat to Kharg Island, but CNBC highlights the specific military confirmation of the Larak Island strike and Iranian retaliation. OilPrice.com focuses more on the broader supply chain anxiety, noting that global buffers are exhausted and diesel shortages are worsening. AP News provides a broader market context, noting mixed global shares and slipping U.S. futures, suggesting the oil spike is part of a wider economic volatility. All sources agree on the severity of the Hormuz disruption, but differ in emphasis: CNBC on the military event, OilPrice.com on the structural supply deficit, and AP on the macroeconomic ripple effects.

Why it matters

The resurgence of direct U.S.-Iran combat threatens to permanently alter the security status quo in the Middle East. With U.S. inventories near minimums and diesel supplies already constrained by Russian bans and refinery damage, any further escalation could trigger a severe global energy crisis, impacting transportation, manufacturing, and inflation globally.

What to watch

Watch for potential U.S. strikes on Kharg Island as threatened by Trump, and monitor Iranian retaliation against U.S. bases in the region. Analysts expect oil inventories to continue depleting in the coming weeks, with diesel margins likely to soar further as supply remains tight. Diplomatic efforts may resume if the conflict escalates, but for now, the risk of a broader regional war remains high.
