Global Crude Oil Prices Climb to One-Month Highs as US-Iran Conflict Escalates

Global crude oil prices rose for a fourth consecutive session on Thursday, July 16, climbing to one-month highs as the intensifying conflict between the United States and Iran around the Strait of Hormuz revived fears of significant supply disruptions across the Middle East.

Where Prices Stand

West Texas Intermediate (WTI), the U.S. benchmark, was trading around $80 per barrel, climbing above the $80 mark and up from a previous close of $79.34. Brent crude, the international benchmark used to price roughly 70% of the world's oil, was trading in the region of $84 to $85 per barrel. Both benchmarks have now risen for four straight sessions to reach their highest levels in a month.

Despite the recent gains, prices remain well below the nearly $120 per barrel peak reached at the height of the conflict earlier this year. WTI's 52-week trading range spans roughly $55 to $118 per barrel, and over the past year the U.S. benchmark is up around 21%.

The Strait of Hormuz at the Center

The rally has been driven almost entirely by the escalating standoff over the Strait of Hormuz, the vital chokepoint through which roughly a fifth of the world's oil supplies passed before the U.S. and Israel launched strikes on Iran on February 28. U.S. forces carried out fresh airstrikes targeting Iranian missile storage facilities and launch sites near the strategic waterway, part of a campaign Washington says is aimed at safeguarding shipping through the strait.

Adding to supply concerns, reports indicated that President Donald Trump is leaning toward broadening U.S. military operations and has discussed the possible seizure of Kharg Island, Iran's primary oil export terminal in the Persian Gulf. The escalation has reversed roughly a third of the second-quarter price decline that had followed an interim peace agreement, which briefly improved the supply outlook. Earlier in the week, Trump abandoned an earlier demand that ships pay a 20% fee on cargo to transit Hormuz under U.S. military protection, after the shipping industry largely opposed the measure and the International Maritime Organization said mandatory tolls in the strait would be illegal.

Additional Supply Pressures

Beyond the Gulf, continued Ukrainian attacks on Russian fuel production facilities and oil tankers have added to worries over tightening global supplies. On the U.S. supply side, Energy Information Administration data showed that domestic crude inventories fell by 1.7 million barrels last week, lending further support to prices.

Ship-tracking firms have observed a steep fall in traffic through Hormuz since renewed fighting erupted, though the U.S. Energy Department said that 8.5 million barrels of oil transited the strait on a single day despite the hostilities, indicating flows have not stopped entirely.

How High Could Prices Go?

Analysts warn the trajectory depends heavily on whether the conflict intensifies further. One analyst told CNBC that the reimposed blockade and renewed hostilities had set the conflict back on an escalatory path, adding that oil "could retest $100 if the current intensity of hostilities persist for a few weeks, or head higher still if regional oil infrastructure is targeted."
