Key Takeaways:
PBF Energy shares jumped 10.5% this week as the benchmark 3-2-1 crack spread surged to nearly $69 a barrel, the highest level in years, after the collapse of a memorandum of understanding with Iran intensified disruptions to crude flows through the Strait of Hormuz.
"The widening crack spread reflects a dual supply shock — crude and refined products are both being squeezed by the Strait's effective closure," said Omar Tariq, an energy analyst covering oil and gas markets. "PBF's advantage is its access to domestic crude, which lets it capture the full benefit while competitors reliant on seaborne barrels struggle."
The 3-2-1 crack spread — which measures the difference between the price of two barrels of gasoline and one barrel of diesel against three barrels of crude — has more than tripled from about $20 at the start of 2026. It stood at roughly $43 as recently as early June, before optimism over a potential resolution to the Iran conflict faded. The Strait of Hormuz, a narrow waterway between Iran and Oman that normally carries about one-fifth of the world's energy shipments, has been mostly blocked since the conflict began on Feb. 28 with U.S. and Israeli strikes on Iran, according to Reuters.
The disruption is not limited to crude oil. Gulf countries are major producers of refined products such as jet fuel and diesel, meaning the Strait's effective closure has choked supply on both ends of the refining value chain. For PBF Energy, which sources most of its crude from domestic U.S. fields, the dynamic has been a windfall: the company's stock has surged roughly 125% in 2026 as crack spreads widened.
International Energy Agency Executive Director Fatih Birol warned Thursday that the world should be "worried" about energy security if the Strait does not reopen in the next few weeks, speaking at a Council on Foreign Relations event. Birol noted that several factors have moderated the price rise so far — including China's stockpile of more than 1 billion barrels accumulated before the war, an IEA-coordinated release of up to 400 million barrels in March, and increased U.S. production — but said those fixes "can't last forever."
The IEA's March release knocked about $20 off oil prices, and Birol said the organization still has 80% of its reserves available to tap if conditions worsen. However, U.S. production increases of 1 million to 2 million barrels per day cannot fully replace the roughly 17 million barrels of oil and refined products that typically transit the Strait daily, he said. The impact has been asymmetric: Asia, which received 80% to 90% of its energy from the Strait before the conflict, has been hit hardest, with developing nations including Pakistan, Bangladesh and India suffering the most severe economic pain.
For PBF Energy, the key question is duration. The longer the Strait remains restricted, the more the refiner stands to benefit from elevated crack spreads. But a prolonged disruption also carries risks: sustained high fuel prices could erode demand, while a diplomatic resolution could send crack spreads collapsing as quickly as they rose. U.S. refiners are already operating near capacity, increasing the risk of unplanned outages that could add further volatility to an already stretched market.
