The ripple effects of war are rarely contained to the battlefield. A conflict thousands of miles away is now showing up directly in your fuel receipts — and if you’re a carrier, owner-operator, or fleet manager, you’re already feeling it. What started as a geopolitical escalation has turned into a global energy shock. Here’s why it’s happening, how bad it is, and what you should actually be doing about it.
The Strait of Hormuz: Why One Waterway Changes Everything
The most immediate driver of rising fuel costs is geography. The Strait of Hormuz — a narrow chokepoint between Iran and the Arabian Peninsula — handles roughly 20% of the world’s oil and gas supply. When conflict escalated in the region, tankers were attacked, exports slowed, and production at several facilities was disrupted or shut down entirely. The result was swift: oil production losses reached millions of barrels per day, crude prices surged into the $120–$150 per barrel range in physical markets, and global oil prices rose 30%–50% compared to pre-war levels. Supply dropped fast. Demand didn’t.
Diesel Is the Real Story for Trucking
Headlines tend to focus on gasoline, but trucking runs on diesel — and diesel is where the pain is concentrated right now. Prices have climbed to around $5 per gallon, up more than a dollar in a short window, and some fleets have seen their fuel costs nearly double. To put that in concrete terms: a truck averaging 6.5 MPG over 2,500 miles per week was spending roughly $1,538 per week on fuel at $4 per gallon. At $5 per gallon, that same truck costs $1,923 per week to fuel. That’s nearly $400 more — per truck, per week. Across a fleet of ten trucks, you’re looking at an additional $16,000 per month in fuel costs alone. That kind of number changes conversations quickly.
Why Trucking Gets Hit Hardest
Every industry that moves goods feels fuel price increases, but trucking absorbs them differently. Fuel typically represents 30%–40% of operating costs for carriers, and unlike some other expenses, it adjusts in real time. Freight rates don’t. When prices spike, there’s almost always a lag before shippers and brokers are willing to adjust what they’re paying. In that window, carriers take the hit. Large fleets can hedge fuel costs or negotiate surcharges in advance. Owner-operators, for the most part, pay market price every time they pull up to a pump. Fuel surcharges help, but they’re an imperfect fix. Most are calculated using weekly or monthly index averages, which means they trail behind sharp price movements rather than tracking them. During a rapid spike, surcharges rarely fully offset the actual cost increase — they just soften it.
Jet Fuel Is in Even Worse Shape
For comparison, jet fuel prices jumped 50%–60% in a matter of weeks, with some regions seeing prices nearly double. Since fuel accounts for roughly 20% of airline operating costs, carriers are already warning of reduced capacity and higher ticket prices. Several have cut routes entirely. This matters to trucking beyond the obvious. When air freight capacity contracts, more freight moves to ground transportation, which adds demand pressure to an already stressed system.
The Downstream Effect on Everything Else
Fuel is a cost that flows through every layer of the supply chain. When transportation gets more expensive, so does everything it moves — groceries, building materials, electronics, manufacturing inputs. Gasoline prices jumped over 20% in a single month, and energy costs are now one of the main accelerants of broader inflation. There are also less obvious costs building quietly in the background. Ships are rerouting to avoid conflict zones, adding time and distance. “War risk” insurance premiums are rising for cargo moving through affected areas. Supply chain timelines are getting less predictable, which creates its own set of problems for businesses that run lean inventory.
Don’t Expect a Fast Recovery
One assumption worth questioning is that prices will snap back quickly once the conflict eases. History suggests otherwise. Even after active hostilities slow, damaged infrastructure takes years to rebuild, production capacity doesn’t return overnight, and markets tend to stay volatile as long as uncertainty lingers. Some analysts project elevated oil prices extending well beyond 2026.
What to Do Right Now
If you haven’t already, now is the time to get precise about your cost per mile — not an estimate, but an actual number that accounts for current fuel prices. If fuel has jumped and your rate structure hasn’t been revisited, you may be losing money on loads that looked profitable three months ago. Revisit your contracts with a specific focus on how fuel surcharges are structured. Fixed or poorly indexed surcharges made sense in a stable environment; they’re a liability in a volatile one. If you have the leverage to renegotiate, use it. If you’re writing new contracts, build in dynamic surcharge language from the start. Beyond the immediate pricing conversation, this moment is also an argument for getting serious about fuel efficiency tracking. Even modest MPG improvements — through routing optimization, driver behavior, or load planning — can meaningfully offset the impact of sustained high prices.
The Bigger Picture
What this situation is really exposing is that fuel is no longer just a line item. It’s a strategic risk that can reshape your margins with very little warning. The carriers that will weather this best aren’t necessarily the ones with the biggest fleets — they’re the ones who know their numbers cold, have flexible pricing structures, and can make decisions quickly when conditions change. The uncertainty isn’t going away. But the carriers who build systems around it — rather than hoping prices return to where they were — will be in a much stronger position when the next disruption hits.
