Crude prices surged on Friday (March 6, 2026) on mounting fears about oil supply disruption during West Asia war, while equities retreated on poor U.S. hiring data.
The U.S.-Israel war on Iran and Tehran’s retaliatory attacks across the Gulf region have upended the world’s energy and transport sectors, virtually halting traffic through the Strait of Hormuz.
The international benchmark oil contract, Brent North Sea crude, surged to $92.69 per barrel, up 8.5% for the day and nearly 30% for the week after U.S. President Donald Trump said only the “unconditional surrender” of Iran would end the West Asia war.
The main U.S. contract, West Texas Intermediate, soared more than 12% to over $90 per barrel, topping off the biggest weekly gain on record.
Maritime traffic has all but dried up through the Strait of Hormuz, through which a fifth of the world’s crude oil and liquefied natural gas supplies run.
Market reaction to the conflict had been tempered by hopes that it would be short, but Trump’s demand for Iran’s capitulation increases the prospect of a long conflict.
Mr. Trump’s comments “dashed hopes that the conflict will be averted quickly, and the oil price has continued its push” higher, said XTB research director Kathleen Brooks.
The prospect of high energy prices for a sustained period has fanned fears of a fresh spike in inflation that could hit the global economy while curbing the ability of central banks to cut interest rates to prop up growth.
“The longer that key energy infrastructure and shipping routes in the region are affected, the greater the chance of a significant inflationary impact,” said AJ Bell investment director Russ Mould.
Attacks on oilfields were reported in southern Iraq and in the northern autonomous Kurdistan region, which forced a U.S.-run oilfield to cease production. Kuwait has also begun cutting production due to a lack of storage capacity, the Wall Street Journal reported.
Earlier this week, Mr. Trump pledged to protect ships through the Strait of Hormuz, but shipping companies have exercised caution in the region.
Mr. Trump’s pledge helped “reduce some of the risk premium in oil markets,” but will have “limited impact unless Iran’s extensive disruption capabilities are first neutralized,” said a note from analysts at JPMorgan Chase.
Meanwhile, data showed the U.S. economy had unexpectedly lost jobs in February, while unemployment also edged up.
The world’s biggest economy shed 92,000 jobs last month, down from revised job growth of 126,000 in January, said the Labour Department.
New data released on Friday (March 6, 2026) also showed U.S. retail sales had fallen by 0.2% in January.
Investors often look at data showing a slowdown in the economy as raising the chances of the US Federal Reserve lowering interest rates, but analysts say higher oil prices complicate that picture.
Until recently, the markets were anticipating the Fed would resume interest rate cuts in June, but that has now shifted to September.
Wall Street’s main indices finished down around 1% or more.
Europe’s main markets finished the day with losses of around 1%.
An exception to Friday’s sell-off was Boeing, which piled on 4.1% following a Bloomberg report that said the company was close to a big sales agreement with Chinese carriers.
