U.S. food inflation pressures are showing renewed persistence across both consumer and producer channels, according to April inflation data and analysis shared during a recent briefing hosted by FMI: The Food Industry Association, which highlighted a convergence of energy, trade and input-cost disruptions flowing through the food supply chain.
The Consumer Price Index (CPI) rose 0.6% month over month and 3.8% year over year in April, reflecting a moderation from March’s monthly acceleration but a firmer annual inflation rate. Core CPI, excluding food and energy, increased 0.4% on the month and 2.8% year over year, both higher than the prior month – underscoring continued broad-based price pressure beyond volatile categories.
At the center of the industry briefing, FMI executives emphasized that inflation dynamics are increasingly being shaped by upstream structural factors rather than short-term shocks alone.
Andy Harig, vice president of tax, trade, sustainability and policy development at FMI, pointed to sustained volatility in global energy markets as a key driver of rising costs throughout the food system. “Recent instability in the global energy markets is contributing to rising production across the entire food supply chain, and it’s putting upward pressure on grocery prices,” Harig said.
He added that these pressures should be viewed as multi-quarter, and potentially multi-year, risks. “Some of these impacts will have ripple effects that are evident now, but it can also be felt later in the year and even into 2027,” he said, citing fuel as a foundational input across farming, processing, packaging and distribution.
Upstream cost inflation is already more pronounced in producer markets. The April Producer Price Index (PPI) rose 1.4% month over month and 6% year over year, a notable acceleration from March, reinforcing expectations that retail food inflation may remain sticky as higher input costs continue to move through the system.
Harig also underscored the growing role of geopolitical disruption in shaping agricultural input costs, particularly the impact of conflict in the Middle East and its effect on global trade routes. Fertilizer, which the U.S. relies on heavily through imports, has been among the most affected categories.
“Fertilizer is essential for food production; the United States doesn’t produce enough to meet its needs,” Harig said. “With the military conflict and a blockade in the Strait of Hormuz right now, cargo ships have been stuck in the region, causing a disruption to, and elevating the costs of ocean freight transport.”
That disruption is filtering directly into farm-level economics at a critical point in the growing season. Economists noted that fertilizer prices – particularly nitrogen-based inputs used in major row crops – have “effectively doubled” in some estimates, significantly compressing margins for producers and increasing the cost base heading into planting and early growth cycles.
Ricky Volpe, professor of agribusiness at California Polytechnic State University, said April CPI data is beginning to reflect early-stage pass-through from these shocks, though the full inflationary impact is still ahead.
“We’re really starting to see some of these factors moving toward inflation,” Volpe said, noting that current readings likely capture only the initial effects of higher energy costs tied to geopolitical instability. Even if conditions improve, he added, “many of these cost pressures will continue to filter through the system well into late summer and the fall.”
Volpe also pointed to a broader set of persistent cost drivers – including labor, packaging, weather volatility, pests and tariffs – that continue to shape food system economics. While some trade-related pressures have eased relative to earlier expectations, he said elevated input costs for key industrial materials such as steel and aluminum continue to indirectly influence food production and logistics.
In the near term, economists expect continued lag effects between producer and retail inflation, with upstream cost increases typically taking weeks or months to fully reach consumers. FMI analysts and industry economists caution that, as a result, inflationary pressure across grocery categories may remain elevated through 2026 and potentially into 2027, depending on the duration of energy market volatility and ongoing global supply chain disruption.
