Eggs are cheaper. Butter is cheaper. Cheese has come down. And yet something feels off every time you push a cart through the produce aisle. That instinct is correct, and economists are now explaining exactly why your grocery bill is about to get more complicated, not less.
Overall grocery inflation slowed to 1.9% annually in March 2026, which sounds like good news. It is, partially. Egg prices dropped nearly 45% year over year following a better winter for farms after last year’s avian flu outbreak, and butter and cheese also saw price relief. But zoom out past the dairy aisle and the picture changes fast.
The Tomato Problem Is Bigger Than Tomatoes
Tomatoes spiked 22% higher than a year ago, driven by a 17% tariff on Mexican imports that was upheld after the Supreme Court declined to strike it down. Ricky Volpe, an agricultural economist at Cal Poly, calls tomatoes “a case study in the ongoing impact of the current administration’s tariffs.”
Volpe goes further than just the tariff, though. He describes the situation as an “inflationary perfect storm” because tomatoes are labor-intensive, energy-intensive, require transportation, and are heavy and spacious. Every one of those cost drivers is currently moving in the wrong direction for consumers.
This is the structural story underneath the headline numbers. A tariff raises the floor price of imported goods. Rising diesel costs raise the price of moving any goods. Labor costs don’t fall just because egg prices do. These pressures don’t cancel each other out. They stack.
Diesel Is the Variable Nobody Is Watching Closely Enough
David Ortega, professor of food economics at Michigan State, warns that perishable foods on the grocery store perimeter will see price hikes first as diesel prices climb due to the war. He calls them “the canary in the coal mine.”
That warning has teeth. WTI crude oil was around $114 per barrel in early April 2026, up from approximately $71 per barrel at the start of March. That is a fast, steep climb. Diesel prices track crude oil closely, and diesel is what moves refrigerated trucks carrying produce, dairy, and meat from farms and ports to distribution centers to your local store.
The perimeter of a grocery store, where fresh produce, meat, and dairy live, is precisely where transportation costs hit hardest. Shelf-stable goods in the center aisles can sit in warehouses. Strawberries cannot.
What the Broader Data Says
The official inflation picture confirms the pressure is building. The Consumer Price Index reached 330.3 in March 2026, up 3.7 points from February. The BEA’s food PCE index showed food inflation accelerating from around 2% year over year in January 2026 to roughly 2.3% in February 2026. And the USDA isn’t optimistic about where this goes: the agency forecasts food-at-home costs will increase more than 3% in 2026.
Consumer sentiment already reflects the anxiety. The University of Michigan Consumer Sentiment index sat at 56.6 in February 2026, near recessionary lows. Households are not imagining the squeeze. They’re feeling it in real time, even when headline numbers look manageable.
Retail sales data adds a wrinkle. Total retail sales reached $738.4 billion in February 2026, the highest in the 12-month observation period. Consumers haven’t stopped spending. They’re absorbing the increases, which means the pain is showing up in household budgets rather than in spending volumes, at least for now.
What You Should Actually Do With This Information
The egg discount is real and worth using. Stock up on shelf-stable proteins, frozen goods, and pantry staples while the relief items are cheap. That’s basic inflation management: buy more of what’s cheap now, less of what’s expensive.
For fresh produce, especially tomatoes and anything else heavily imported from Mexico, expect prices to stay elevated as long as the tariff structure holds and diesel stays above $100 per barrel equivalent. There is no near-term policy reversal visible on either front.
The structural point Volpe and Ortega are both making is that the easy part of grocery inflation is the part that’s already happened. The harder part, driven by energy costs, tariffs, and labor, is still working its way through the supply chain. The perimeter of your grocery store is where you’ll feel it first.
