The contraction in grocery volume began in mid-2025, but recent data from Bain & Company and NielsenIQ confirms an acceleration since February. While grocery prices continue to climb by 2% to 3% annually, unit sales dropped 1.8% year-on-year in June. This volume decline is widespread, affecting every region as consumers actively reduce their basket sizes to manage tighter budgets.

Multiple economic pressures are converging to drive this shift. A 20% spike in gas prices in March compounded the impact of a 33% cumulative rise in grocery costs since 2019. Additional factors, such as reduced SNAP participation and the rising popularity of GLP-1 weight-loss medications, are further suppressing demand. According to Bain’s recent pulse survey, 80% of Americans are now actively attempting to trim their overall spending, with more than half of those individuals trading down to cheaper store brands or relying more heavily on coupons.

Retailers are now operating in a environment where growth is no longer guaranteed by market expansion. Success now depends on a retailer’s ability to build a credible value proposition through precise pricing and loyalty initiatives. Kurt Grichel, head of Bain’s Americas Retail practice, noted that the path back to growth requires more than just low prices; retailers must create a value story that resonates with shoppers and AI agents alike. Those who refine their assortment and promotion strategies now are the most likely to capture the remaining consumer trips as broader economic conditions remain volatile.
