U.S. grocery slowdown deepens as shoppers buy fewer items, raising pressure on food companies

U.S. grocery units fell 1.8% y/y in June (vs. +0.1% in June 2025) as shoppers bought fewer items while prices rose ~2%-3% y/y, and Bain estimates grocery prices are ~33% higher than in 2019. Demand pressure is spilling into food makers: PepsiCo reported North American food revenue down 2% with volume flat, citing weaker consumer spending and increased promotions/lower effective pricing. Retailers (e.g., Walmart and Kroger) are responding with targeted price cuts and value promotions, but Bain suggests unit growth will hinge on grocers priced sharply on high-notice items.

Analysis

The key market mechanism is margin transfer: when baskets shrink, branded CPG loses pricing power first, while the grocers with scale, loyalty data, and private label can still defend traffic and push vendor funding. That argues for relative strength in WMT and, to a lesser extent, KR, while PEP is the clearest pressure point because snacks/beverages are easy trade-down targets and promo intensity rises fastest there. Second-order effect: private-label penetration should keep rising, which is structurally negative for branded mix and positive for retailers that own the shelf space.

Near term, the tape may initially reward anything perceived as “defensive,” but the real catalyst path is the next 1-3 monthly scanner prints and the next earnings season. If unit trends remain negative, consensus will have to cut organic sales assumptions before it cuts EPS, because the industry can buy volume with promotions only by surrendering price/mix. The main falsifier is a quick normalization in gas prices and SNAP-linked demand, which would let the consumer trade back up and mute the promo war.

The contrarian view is that this is more a value-seeking consumer than a collapsing consumer: if households are simply reallocating to cheaper baskets, total dollars can stabilize faster than bearish models imply. That makes an outright short on broad staples less attractive than a relative-value trade against the most mix-sensitive name. Watch whether WMT/KR can keep traffic growing without materially sacrificing margin; if they can’t, the “winner” case becomes much less durable.

Key Decisions for Investors

• Long WMT / short PEP for the next 6-10 weeks: best expression of trade-down and private-label share gain versus the most promo-exposed branded supplier; risk/reward improves if scanner data stay negative.
• If you want a cleaner relative pair, long KR / short PEP into the next quarterly cycle: KR should capture value-seeking traffic, but size smaller because grocery inflation relief can still compress gross margin.
• Do not chase an outright short KO here; KO is exposed to price pressure but has better beverage resilience than PEP’s snack/food mix, so the cleaner short is PEP.
• Set a watch item on monthly unit data and gasoline: if fuel retreats and unit trends turn less negative for two consecutive reads, cover PEP shorts and expect a relief rally in staples.
• Consider XLP underweight versus XRT only if the next scanner prints confirm continued volume contraction; otherwise the sector may simply rotate within staples rather than de-rate.
