Iran Conflict Drives Oil Prices Near $100, Diesel Hits Record High
Brent crude oil rose 4.6% to $94.65 on September 1, marking the highest close since July 24; West Texas Intermediate rose 5.2% to $90.22. This week, Brent briefly surpassed $95, with traders refocusing on $100.
Diesel is tighter. U.S. diesel futures reached a 52-month high, rising about 51% over the past ten weeks; the crack spread is approximately $107/barrel according to London Stock Exchange Group data, a record. New York Harbor wholesale diesel rose nearly 7% to $4.71 per gallon. The national retail average is about $5.69 per gallon, close to the wartime peak of April and the historical high of $5.80 in May 2022. The Intercontinental Exchange diesel crack also hit a record high of about $79/barrel, with the September to November spread at about $80/ton. European natural gas futures reached their highest level in 2023, rising about 11% this week.
Supply risks stem from the Strait of Hormuz, damage to Gulf refineries, and Ukraine's strikes on Russian refineries. Goldman Sachs stated that global refinery throughput is about 7 million barrels per day lower than last year, with seasonal lows nearly 6 million barrels per day since March. S&P predicts Middle Eastern refining capacity will be about 8 million barrels per day in 2026, down 1.6 million barrels from 2025. U.S. refinery utilization is about 97%. The Energy Secretary stated that 17 million barrels of crude oil crossed the strait on Monday, the highest single-day figure since the war began, but the number is in doubt. Trump has summoned refinery executives to demand increased diesel and gasoline production. Brown University estimates that since the war began, Americans have paid an extra $52.3 billion for gasoline and $43.4 billion for diesel, averaging about $731 per household.
Energy costs are impacting freight, agriculture, construction, and household bills. The European Central Bank and the Bank of Japan have raised interest rates due to war-induced inflation, prompting the market to reassess the Bank of England's rate hikes this year. The World Bank has warned that if the conflict lasts more than six months, inflation could reach 4.5%. About one-third of OECD fixed-rate debt will mature between 2026 and 2028. Fossil fuel subsidies are expected to reach $1.1 trillion by 2026.
Who is buying and who is selling: The event is driven by expectations of refined oil supply shortages, not a sudden expansion of global demand. Traders and air freight companies are buying diesel paper contracts and hedging cracks; accounts betting on a restoration of the strait are selling long-term contracts. Benefiting are U.S. refiners with nearly $90/barrel diesel processing margins, while emerging market finances for freight, agriculture, and imported energy are under pressure. Funds are flowing from the crude curve to middle distillate cracks, with the interest rate market interpreting the war as a more persistent supply-side inflation.

The diesel shortage in 2022 stemmed from the exit of Russian seaborne refined oil, and 2026 will see both Gulf and Russian refineries cut. Crude oil can be rerouted, but middle distillates heavily rely on specific facilities. The crack spread exceeding $100 indicates a bottleneck in distillation towers, not in oil wells. Trump's summoning of refiners to the White House is an attempt to frame oil prices as an administrative issue in an election year, which does not change the risks of shipping through the Strait of Hormuz.
The capital path indicates that the war simultaneously raises energy subsidies and defense spending, while sending maturing government bonds into higher nominal interest rates. Money flows from household fuel tanks and fiscal subsidies to refinery profits and inflation-protected bonds. Emerging markets will also face impacts from fertilizer and remittance shocks, seeking new funds from the IMF.
The comparative reference is the 2022 European gas crisis and U.S. diesel shortage, as well as the 2008 oil price peak, though the crack spread was not as extreme. The industry's position is in the middle of a wartime supply shock: low inventories, damaged refining capacity, and seasonally rising demand, with control resting in the strait and drone ranges.
The structural change is a shift in pricing power. The mechanism is that crude oil pricing still looks at barrel counts, while real inflation looks at diesel; when cracks hit record levels, central banks face a refinery capacity gap that cannot be immediately repaired through interest rate hikes, leading the bond market to rewrite the war premium from short-term risk to term premium.
