Brent Crude Slips to $93.49 but Still $23 Above Pre-War Level

Why is diesel still expensive if oil prices are dropping?

Brent crude fell $1.49 to $93.49 a barrel on June 2, but the international benchmark remains $23 above the roughly $70 level it traded at before the war shut the Strait of Hormuz. That 33% premium over the pre-war baseline is still flowing through to the pump. The Hormuz closure has not been resolved, and no agreement to reopen the strait has been reached.

The $93.49 Brent price translates directly to what small fleets pay for diesel. Every $10 move in crude typically shifts retail diesel by 25 to 30 cents per gallon within two to three weeks. At $93.49, Brent is still pricing diesel well above the $3.50 to $3.80 range most carriers budgeted for 2026. Gasoline hit $4.48 a gallon in early May, up 50% since the Iran war started, and diesel has tracked a similar trajectory.

What the $23 oil premium costs a 10-truck fleet

A 10-truck fleet running 1,000 miles per truck per week at 6 mpg burns roughly 1,667 gallons weekly. The $23 Brent premium over pre-war levels adds approximately 60 cents per gallon to diesel. That is $1,000 per week, or $52,000 annually, in fuel cost that did not exist in the January budget. For an owner-operator running 2,500 miles weekly in a single truck, the premium is $250 per week, or $13,000 per year.

Fuel surcharges have not kept pace. Most contract fuel surcharge tables reset weekly based on the Department of Energy's national diesel average, but those tables were written when diesel traded in a $3 to $4 range. The current spike has pushed many loads into surcharge bands that do not exist in older contracts, leaving carriers to absorb the difference. Spot loads often include no fuel surcharge at all, forcing the carrier to eat the entire cost.

Hormuz remains closed, no timeline for reopening

The Strait of Hormuz, which handles roughly 20% of global oil shipments, remains closed with no agreement in place to reopen it. The closure has forced crude tankers to reroute around Africa or through alternate pipelines, adding cost and time to every barrel. That logistical premium is baked into the $93.49 Brent price and will not disappear until the strait reopens.

The $1.49 drop on June 2 reflects short-term trading, not a structural shift. Brent has traded in a $92 to $97 range for three weeks, and the lack of progress on Hormuz means the floor remains elevated. Small fleets planning fuel budgets for the next quarter should assume diesel stays above $4.20 per gallon until the strait reopens or alternate supply routes stabilize.

The fuel cost squeeze on settlement statements

Fuel is now the largest line item on most settlement statements, surpassing driver pay in many cases. A truck running 2,500 miles weekly at 6 mpg and $4.50 diesel spends $1,875 on fuel. At the pre-war $3.50 diesel price, the same truck spent $1,458. The $417 weekly difference is $21,684 annually per truck. For a 10-truck fleet, that is $216,840 in fuel cost inflation that must come out of margin or be passed to shippers.

Shippers have resisted rate increases. Contract rates have been flat for three months running, and spot rates remain under pressure in most lanes despite the fuel spike. Carriers are caught between a fuel cost that has jumped 33% and a rate environment that has not moved. The result is margin compression across the board, with smaller fleets feeling it first.

What changes for small fleets

Small fleets should lock fuel where possible. Some truck stops and fuel card programs offer price caps or fixed-rate contracts for fleets willing to commit volume. The cost to lock fuel at $4.30 for 90 days may look expensive today, but it is cheaper than riding a spike to $5 if Hormuz stays closed into August.

Negotiate fuel surcharges on every contract renewal. The standard DOE-based fuel surcharge table does not cover the current price environment. Carriers should push for surcharge tables that start at a lower baseline or include higher bands to capture the Hormuz premium. On spot loads, build fuel into the rate quote and make it non-negotiable. A load that pays $2.10 per mile with no fuel surcharge is a $1.85 load when diesel is $4.50.

Plan for diesel to stay elevated through Q3. The $93.49 Brent price is not a spike, it is the new baseline until Hormuz reopens. Budget accordingly, and do not assume a return to $3.50 diesel this year.
