Had your grocery bill finally stopped climbing? Energy prices rose 20.4% in September 2026, the largest increase since May, the Bureau of Labor Statistics said on Wednesday, according to a Business Insider report from October 15, 2026. Food prices have held fairly steady this year. But rising fuel and transportation costs now threaten to make that relief short-lived, the outlet reported.
What changed: fuel costs are rising while food prices held steady
Much of September’s faster headline inflation was driven by the energy increase, according to the BLS. Business Insider reported that attacks on oil tankers and energy infrastructure in Iran, Saudi Arabia and Russia have complicated the global supply of diesel. That is likely to raise transportation costs across the economy in the coming weeks and months, the outlet said. It added that higher fuel and energy costs significantly affect the cost of producing and distributing food, even for grocery stores thousands of miles from the Strait of Hormuz.
Following the cost from the fuel pump to the shelf
When diesel costs more, it costs more to make and deliver food, and companies may pass some of that onto shelf prices. Grocery chain Albertsons said on an earnings call Tuesday that its business is being squeezed by two things: higher gas prices for US shoppers and higher diesel prices in its own operations, Business Insider reported. Spice maker McCormick said earlier this month that it now anticipates 7% inflation in its financial forecasts, due in part to energy challenges. ‘We’re facing more costs, both in terms of raw packaging, but also freight, primarily freight costs due to fuel, as well as capacity constraints in the US,’ McCormick CFO Marcos Gabriel said on an earnings call, according to Business Insider. Food company Conagra projected higher prices in its business through the rest of the year because of accelerating fuel and transportation costs. Its brands include Birds Eye, Slim Jim and Marie Calendar’s (spelled that way in the source). Business Insider noted that the reversal of many of President Trump’s tariffs had given shoppers some stability on grocery prices. Walmart and Costco said they were investing much of their tariff refunds into lower prices.
Our math: what a 7% increase could mean for one grocery line
This is a hypothetical illustration, not a forecast. McCormick’s 7% figure is its expected cost inflation, not a announced price increase. Suppose a household spends $20 a month on spices and seasonings, and the full 7% were passed on to shoppers. The monthly cost would rise by $20 x 7% = $1.40. Over a year, that is $1.40 x 12 months = $16.80. Companies may pass on less or more than their costs, so actual shelf prices could differ. The increase adds up month after month rather than compounding.
What to check this week, and what to watch next
Check the unit price on items you buy often. That is the price per ounce or pound, usually printed on the shelf tag. Compare it now and again in a few weeks to see whether higher freight costs reach the shelf. Next, watch the BLS’s next monthly consumer price report to see whether energy prices keep rising and whether food prices start to move. Also watch for further earnings comments from large food companies and retailers.
