Oil prices rose on Friday morning as investors continued to assess the impact of the U.S.-Iran war on global energy markets.

By 6:58 a.m. ET, global benchmark Brent crude futures added 4.5% to trade at $89.23 a barrel, notching a fresh 52-week high and levels not seen in nearly two years. U.S. West Texas Intermediate crude futures were last seen 6.3% higher at $86.06, hitting their highest level since April 2024.

Prices dipped overnight as investors continued to assess the impact of the U.S.-Iran war on global energy supply.

Crude prices are on track for their biggest weekly gain since Russia’s full-scale invasion of Ukraine in early 2022.

The spike comes as the U.S.-Iran conflict spreads across the Middle East, disrupting energy production and bringing traffic in the Strait of Hormuz, a critical shipping route, to a near standstill.

On Friday morning, the Financial Times reported that Qatar’s energy minister said the war in the Middle East could see Gulf energy exporters stop shipments within days. Saad al-Kaabi told the FT that crude prices could reach $150 a barrel in the coming weeks if oil tankers were unable to pass through the Strait of Hormuz.

Prices briefly dipped overnight after the U.S. issued a 30-day waiver to India — the world’s third-largest oil importer — to resume purchases of Russian oil. Washington had earlier imposed 25% “penalty” tariffs on India for buying Russian crude, which were revoked last month. The retreat in prices also came after news agency Reuters, citing an unnamed White House official, reported that the U.S. Treasury is planning to announce measures to curb energy price spikes, including potential interventions in the oil futures market.

The average price for a gallon of regular gasoline jumped nearly 27 cents since in the week to Thursday to $3.25, according to data from U.S. travel organization AAA.

The conflict between Iran and the U.S. enters its seventh day on Friday. In a press conference on Thursday, U.S. Defense Secretary Pete Hegseth said the U.S. had “only just begun to fight.”

“Iran is hoping that we cannot sustain this, which is a really bad miscalculation,” he told reporters.

“There’s no shortage of American will here … If you think you’ve seen something, just wait. The amount of combat power that’s still flowing, that’s still coming, that we’ll be able to project over Iran is at multiples of what it currently is right now when you add up our capabilities and those of the Israeli Defense Forces.”

“Contrary to what consensus thinks, I think higher energy prices could actually be deflationary for the U.S.,” Atakan Bakiskan, chief U.S. economist at Berenberg, told CNBC’s “Squawk Box Europe” on Friday.

Oil prices have soared after U.S. and Israeli strikes on Iran continued on Sunday night.

Brent crude prices hit a new 52-week high on Monday, surging 9.3% to reach $79.40, while U.S. West Texas Intermediate prices also rose more than 9% to $73.10.

U.S. President Donald Trump said the “overwhelming military offensive” — which he has dubbed Operation Epic Fury — would continue until the U.S.’s objectives are achieved. Israel launched fresh strikes against both Iran and against Hezbollah targets in Lebanon late on Sunday, which came after Iran attacked military and infrastructure targets across several countries in the region.

As the U.S. continues to target Iranian air defense systems and naval capabilities, global oil supplies have come into sharp focus.

Amrita Sen, founder and director of research at Energy Aspects, told CNBC on Monday that she expects oil prices to likely hold at around $80 level for some time.

Sen said that it is unlikely that the Strait of Hormuz — through which 13-15 million barrels, or 20% of global supply, of oil flows — would be closed altogether. She added that the bigger risk stems from one-off attacks on vessels passing through the area.

Sen said that the U.S. and Israel have the superior military power to ultimately neutralize Iran’s ability to completely shut off the Strait, a key shipping channel for oil producers such as Saudi Arabia, the UAE, Iraq, Iran, and Kuwait.

But single attacks on ships are more difficult to prevent. “This is something we’ve warned right throughout to our clients,” she said.

After three tankers were hit over the weekend, shippers are now being extremely cautious about going in, she added.

“That is the biggest issue right now — how do Asian refiners actually get the volumes from the Middle East?” Sen added.

She noted that Oman and certain UAE grids can bypass the Strait, while Saudi Arabia has contingency plans to move its oil through the East-West pipeline via the Red Sea.

“But even if you are able to move 5 million out through other methods, about 10 is still stuck,” she added.

Sen added that, if energy infrastructure is hit, the price of oil could hit $100.

She added that “the stakes are just too high” when it comes to potential attacks on infrastructure.
