Your Prices Are Next - URL: https://www.zilck.com/diesel-hit-6-your-prices-are-next/ - Published: 2026-09-15T00:24:28.000Z - Updated: 2026-09-15T00:24:28.000Z - Description: Most businesses haven't felt it yet. That's the dangerous part. - Author: Zilck Team - Tags: Business The national average price of diesel hit $6.05 a gallon on September 11, up from $3.70 a year earlier and $3.76 just before the Iran war closed shipping through the Strait of Hormuz in late February. That's a 60% increase in roughly six months, and it's adding about $300 million a day in cost across the U.S. economy, [Axios reports](https://www.axios.com/2026/09/11/diesel-fuel-prices-food-transportation?ref=zilck.com). Most businesses haven't felt it yet. That's the dangerous part. Freight contracts, fuel surcharge schedules, and retailer margins are absorbing the shock right now, which means the bill arrives later, larger, and on a timetable you didn't choose. ## The Bill Is Already in Transit Crude is trading near $94 a barrel, up from $72.50 before the war. California is heading past $8 a gallon with stations already above $9, and 47 of the 50 states have seen diesel climb more than $2 a gallon in a year. "Early on, much of the cost increase gets absorbed along the supply chain through existing freight contracts and retailer margins," says David Ortega, a food economics professor at Michigan State University. That absorption is temporary by definition. Contracts reprice. Surcharges catch up. And nobody credible is calling this a spike to wait out. "The market is not returning to calm, it is adjusting to the new normal," says Jim Burkhard, global head of crude oil research at S&P Global. Whatever you think of the phrasing, the planning implication is clear: this is a 2027 budget input, not a bad quarter. ## The Lag Costs More Than the Price Here's the mechanic that separates companies that survive a fuel shock from companies that quietly bleed through one — and it has nothing to do with the price at the pump. Fuel surcharges are supposed to be neutral. They rise when diesel rises, and the cost passes through. But most surcharge schedules reset monthly or quarterly, and in a market moving this fast, the schedule is the problem. During one week in March, diesel jumped 96 cents a gallon. Run the arithmetic on a 55-truck fleet. Resetting its surcharge monthly, it ate roughly $168,000 in unrecovered fuel costs. Resetting quarterly, more than $400,000, [according to Commercial Carrier Journal](https://www.ccjdigital.com/business/finance/article/15827534/how-the-2026-diesel-surge-is-costing-trucking-fleets-hundreds-of-thousands?ref=zilck.com). Same trucks, same diesel, same contracts — the only variable was how often somebody updated a number. "Fuel surcharges are meant to be a neutral pass-through," says Matt Cartwright, CEO of Magnus Technologies. "In a volatile market, manual or infrequent updates create a gap between actual fuel costs and what gets charged." That gap exists in your business too, wherever you set a price based on an assumption about freight. A quarterly review cycle means losing money for up to 89 days. ## Who Pays First The cost lands unevenly, and perishables take it hardest — they move constantly, they need refrigeration in transit, and much of what they're made of is harvested with diesel equipment. Seafood prices ran 7% above last year in July; fresh produce, 4.9%. The Independent Grocers Alliance estimates fuel accounts for 15% to 30% of food costs. Executives have stopped hedging about it on earnings calls. "I would expect that the pressure is actually going to mount," Kroger CEO Greg Foran said. Smithfield Foods CFO Mark Hall put the timing plainly: "That impact is beginning to flow through in the second half of the year." Hormel's interim CEO Jeffrey Ettinger named the cause directly, and Newell Brands CFO Mark Erceg said inflationary impacts are running past estimates, pointing at resin and "direct transportation costs, i.e., diesel." The pass-through is already visible downstream. Amazon added a temporary 3.5% fuel and logistics surcharge on third-party sellers. UPS, FedEx and USPS have layered on package fees. If you sell physical goods, someone has already repriced you — check your carrier invoices before you finish reading this. ## The Squeeze Has Two Sides One more thing worth putting on the same page, because it rarely is. Inflation ran 3.4% in July, well above the Fed's 2% target, and Fed chair Kevin Warsh has said prices are the "predominant focus" right now. Markets are pricing in meaningful odds of a rate increase at the September 16 meeting. So the plausible near-term scenario is freight costs rising while borrowing costs rise with them. Working capital gets more expensive at exactly the moment you need more of it to carry inventory through a price shock. Planning for one and not the other is how a solvent business becomes a cash-flow casualty. ## What This Means You have three options and should pick deliberately rather than by default. **Absorb** only where you have real pricing power and a short exposure — a one-quarter margin hit to protect a key account is a strategy. Absorbing because nobody wanted the conversation is not. **Surcharge** when the cost is visibly external. A separate, clearly labeled fuel line is easier for customers to accept than a base-price increase, and it's reversible when diesel falls. Tie it to a published index and update it weekly, not quarterly. **Reprice** when your costs have structurally shifted, which — at 60% — is most likely the honest answer. Repricing once with a clear explanation beats three apologetic increases over a year. Whichever you choose, shorten the review cycle first. The $168,000 gap wasn't caused by diesel. It was caused by a calendar.
