WTI crude rises 1.5% to $80.65 as Iran tensions fuel supply fears

WTI crude climbed 1.5% to $80.65 a barrel on Tuesday, extending gains as the Strait of Hormuz closure and fading shock absorbers from the US-Iran conflict kept supply risks front and center for traders.

"The market is repricing the probability that the temporary buffers that capped prices in the first half of the year are running out," said Jorge Leon, geopolitical analysis head at Rystad Energy. "The SPR drawdown was a one-time tool, and China's import cuts have limits."

Brent crude futures traded near $83 after recovering from an intraday low of $81.28, though the global benchmark remained down more than 6% on the day, according to Reuters data. Gold briefly pushed above $4,100 before settling near $4,083, while the US Dollar Index firmed at 101.40 as traders priced a 33% probability of a Federal Reserve rate hike this week, based on the CME FedWatch Tool.

The five-month-old war between the United States and Iran has already reshaped global oil flows, yet the doomsday forecasts of $150 to $200 crude never materialized. Brent peaked around $126 a barrel after the Feb. 28 strikes that triggered Tehran's closure of the Strait of Hormuz, a chokepoint carrying roughly a fifth of the world's oil. The national average for US gasoline hit $4.56 a gallon on May 21, well below the $5.60 that $150 oil would have implied, according to AAA. But the cushions that prevented that outcome are thinning.

The buffers that capped prices are fading

Four factors kept the oil market from spiraling. China, the world's largest oil importer, slashed crude purchases to their lowest in nearly a decade by June, curbed fuel exports and shifted drivers toward electric taxis. US domestic production hit a record 13.93 million barrels a day in April, while Washington drained the Strategic Petroleum Reserve as part of a coordinated 400 million-barrel IEA release in March. Saudi Arabia rerouted crude through its Red Sea port at Yanbu, partly replacing barrels stranded behind Hormuz. And traders simply stopped chasing headlines — liquidity thinned, funds refused to build large bullish positions, and the market went numb to each new announcement.

Most of those buffers are now one-time moves. The SPR fell to 311.4 million barrels last week, its lowest level since March 1983, after giving up more than 104 million barrels since the war began, AAA reported. That cushion does not refill quickly. China can only cut imports so far. Saudi Arabia's Yanbu workaround carries its own risk, with roughly 2.5 million barrels a day exposed to Houthi threats.

What $80.65 crude means for the pump and the economy

AAA's rule of thumb holds that every $1 move in crude translates to 2.4 to 2.5 cents a gallon at the pump. With WTI at $80.65, the national average for regular gasoline has climbed back above $4 for the first time since June 17, AAA said. Diesel, which sets the cost of nearly everything trucked to grocery stores, hit $5.14.

For a two-car household burning 1,000 gallons a year, the gap between the $2.98 a gallon on the day the war started and today's $4.02 works out to about $1,040 in additional annual fuel costs. That is roughly the difference between funding a Roth IRA and deferring it another year.

The transmission chain extends beyond the pump. Higher energy prices feed into core inflation readings, complicating the Fed's rate path. Markets currently assign a 33% probability of a rate hike at this week's Federal Open Market Committee meeting, with the implied likelihood of a September increase near 79%, according to the CME FedWatch Tool. A hawkish hold that pushes expected rate hikes further out the curve would keep the dollar supported, OCBC strategists said, while a dovish communication error risks lifting long-end inflation breakevens.

Iranian Foreign Ministry spokesperson Esmaeil Baghaei said conditions in the Strait of Hormuz had not changed and the key shipping lane remained closed. US Ambassador to the United Nations Mike Waltz said President Donald Trump is allowing space for negotiations while maintaining that all military options remain available.

The two numbers to watch are the SPR level and Yanbu shipment volumes. One is running low, and the other carries its own geopolitical risk. If a ceasefire does not materialize, the risk of a significant rebound in oil prices would be substantial, Rystad's Leon said.
