Oil dipped slightly on Friday but stayed on track for a second straight weekly gain, as traders digested Washington’s stark warning of “the toughest sanctions in history” on Iran, an open-ended threat with no end in sight for Middle East supply disruptions.
By 08:02 GMT, Brent crude futures had slipped 17 cents, or 0.18%, to $93.61 a barrel, while U.S. West Texas Intermediate crude shed 36 cents, or 0.41%, to trade at $86.47.
The dip was a modest pullback after a week of sharp gains: Brent has climbed more than 5.8% since Monday, and WTI has advanced 4.8%, with both benchmarks touching their highest levels since July 24 in the previous session.
The latest leg up in prices traces back to an unmistakable shift in tone from the United States. “The U.S. is taking a very firm stance against Iran, with the blockade back in place and threats of tougher sanctions on Iranian oil exports, and that’s why we are seeing oil prices back above $90 a barrel,” said Soni Kumari, an analyst at ANZ.
The sanctions threat was delivered by U.S. Treasury Secretary Scott Bessent, who framed the potential measures not as an escalation but as an alternative to further military action, suggesting that squeezing Iran’s oil revenue could reduce the need for new major operations on the ground. Markets, however, appear to be reading the message differently: as a signal that the standoff is entrenching rather than easing.
That reading was reinforced by the collapse of diplomacy this week. The earlier peace deal struck between Washington and Tehran expired without either side making a visible effort to restart negotiations, removing what had been one of the few off-ramps available to de-escalate the crisis.
Beyond the sanctions rhetoric, traders are also contending with tightening supply out of the Gulf. Continued curtailment of output from major producers Saudi Arabia, Iraq, the United Arab Emirates and Kuwait has added a second layer of upward pressure on prices, compounding the geopolitical risk premium already baked into the market.
“The market is starting to adjust to the fact that oil trade and supply conditions are unlikely to return to prewar levels anytime soon,” Kumari added, a comment that captures the broader mood among analysts: this is no longer being treated as a temporary shock, but as a structural repricing of Middle East supply risk.
Nowhere is that risk more visible than in the Strait of Hormuz, the narrow waterway that has long served as the world’s most critical oil chokepoint. Ship-tracking data from Kpler showed just seven commodity vessels transited the strait on Thursday, barely half the number that passed through the previous day.
Before U.S.-Israeli strikes on Iran began in late February, the Strait of Hormuz carried roughly a fifth of the world’s combined oil and liquefied natural gas supply. Nearly six months into the conflict, that flow remains impaired, with shipping activity through the corridor still well below prewar norms.
The conflict’s reach extended further this week beyond the Gulf. Ukraine’s military said Thursday it had struck Russia’s TANECO oil refinery in the Tatarstan region, along with the Tamanneftegaz oil terminal in the Krasnodar region, according to Ukraine’s General Staff, underscoring how energy infrastructure has become a recurring target in a war now stretching across multiple fronts.
Taken together, the week’s developments a harder U.S. line on Iran, stalled diplomacy, tightening Gulf supply, thinning traffic through Hormuz, and strikes on Russian refining assets paint a picture of a market bracing for prolonged disruption rather than a swift return to normal.
For now, prices are pulling back only modestly from multi-week highs, a sign that traders see little reason to expect the risk premium to fade soon.
WHAT YOU SHOULD KNOW
Oil is climbing not on a single shock but on a hardening standoff: Washington’s threat of unprecedented sanctions on Iran, a collapsed peace deal, and shrinking Gulf supply are combining to convince markets that disrupted Middle East oil flows are becoming the new normal, not a temporary blip. That’s the key factor: this is a structural repricing of risk, not a passing spike.
