U.S.-China Relations
NextFin News - Americans are still feeling inflation pressure at the grocery checkout even as supermarket price growth slows to its lowest levels in years, Aldi's US chief operating officer said in a Sept. 22 interview. The comment captures the central tension of the US consumer story in late 2026: the flow of food-price inflation has cooled sharply, but the cumulative level of prices has not come back down, and households have changed the way they shop as a result.
The statement from Karla Waddleton, who became Aldi US chief operating officer in July 2025 after rising through two decades of store and division operations, lands at a moment when the official data and the lived experience of shoppers are pulling in opposite directions. Understanding that gap — and what it implies for retailers, wages, and the Federal Reserve's last mile of disinflation — is the real story.
The Situation: Inflation Cools, But the Bill Stays High
The latest Consumer Price Index from the Bureau of Labor Statistics, released Sept. 11, shows food-at-home prices flat in August and up 2.2% over the year — the slowest grocery inflation of the current cycle. The broader food index rose 0.1% for the month and 2.7% annually, while food away from home climbed 3.4% year on year, keeping restaurant inflation well above supermarket inflation. Full-service restaurant prices rose 3.5% and limited-service meals 3.2%, a spread that matters for supermarkets competing for meal occasions with ready meals, deli, and private-label solutions.
On the surface, that is a relief story. But the relief is uneven. Egg prices jumped 2.9% in August alone, non-alcoholic beverages rose 3.7% over the year, and fruit and vegetable prices — down 0.4% for the month, the third consecutive monthly decline — were still 3.2% higher than a year earlier. Lettuce prices dropped 6.2% during August following a 16.4% fall in July, yet the produce basket remains above the overall grocery rate. Dairy moved 0.3% higher in the month but stayed 0.3% cheaper than a year earlier, giving retailers a rare value-lever category.
The Agriculture Department expects food-at-home prices to rise 2.5% across 2026, slightly below the 20-year historical average of 2.6%. All food is forecast to rise 3.0% and food away from home 3.6%. But the category-level picture is anything but average: beef and veal prices are forecast to jump 9.8% this year, with a range of 7.0% to 12.6%, and fresh vegetables are forecast up 5.9%, with a range of 4.0% to 8.0%. Faster-than-average growth is also expected for fresh fruit, sugar and sweets, fish and seafood, and non-alcoholic beverages, while dairy is forecast to be broadly unchanged.
This is where the gap between statistics and lived experience opens up. A 2.2% annual rate feels manageable in the abstract. What a household actually feels is that the grocery bill that used to be $150 is now structurally higher, and that the categories it visits most often — eggs, produce, beverages — keep delivering fresh surprises. The headline rate is an average across hundreds of items; the shopper's experience is dominated by the five items in the cart that moved this week.
Why the Pressure Persists: Level Effects, Not Flow Effects
The key distinction is between the flow of inflation and the level of prices. Food-at-home inflation peaked at 11.4% year on year in August 2022, the highest since 1979, then spent the next three years decelerating through 10.9%, 5.8%, and 2.8% before reaching 2.2% in August 2026. The flow has normalized. The level has not reverted.
Every year of above-trend food inflation compounds into a permanently higher price deck, and households do not get a refund when the rate slows. Cumulatively, food-at-home prices are roughly a quarter higher than they were before the 2021-2022 surge. That is not a statistic a family absorbs and forgets; it is a permanent downgrade in purchasing power that shows up every time the card is swiped.
Research from the Peterson Institute for International Economics explains why a small category can dominate perception: consumers judge inflation by how often they buy something, not by its budget share. Eggs make up less than 0.2% of the CPI basket, yet an avian-flu-driven egg shock can define a family's entire sense of how bad inflation is. Frequency beats weight in the human experience of prices. That mechanism is why a discount grocer's executive can say Americans are feeling pressure while the official grocery index prints 2.2%. The pressure is no longer broad-based. It is concentrated, salient, and repeated every week at checkout.
The Structural Shift: Trading Down Is Sticky
The more important story is what households are doing about it. Jason Hart, Aldi's former US chief executive who is now group chief operating officer of Aldi South, put it directly in a mid-September interview: "Value is always on trend. It's not as if all of a sudden the unemployment situation stabilizes or inflation lessens and they go back to where they were shopping before, that's just not the case. They stay, they shop with us. They like the quality, and they really like the savings. The growth is sticky for us, for sure."
This is the structural call. The 2022 inflation shock did not just change prices; it changed behavior. Households that had never shopped a discount format discovered it, tried private label, and found the quality acceptable. Once that switch is flipped, it does not flip back automatically when inflation cools. Hart's read is that value-seeking has become a permanent preference rather than a cyclical reaction.
The evidence is in the numbers. One in three US households shopped at Aldi over the past year, according to Aldi US chief executive Atty McGrath. In 2025 alone, 17 million new customers visited Aldi stores. Store visits rose 8% year over year in 2025, outpacing the overall grocer sector at 3.1% and major competitors including Costco at 5.9%, Albertsons at 1.6%, Kroger at 0.8%, and Walmart at 0.5%, according to location-analytics firm Placer.ai. Aldi, which had 2,614 US stores as of Dec. 31, 2025, is on track to operate nearly 2,800 by the end of 2026 and has set a goal of 3,200 stores by the end of 2028, backed by $9 billion of US investment through 2028.
The shift is not confined to lower-income households. Placer.ai has found Aldi capturing middle- and higher-income shoppers earning $75,000 to $125,000 a year, and the retailer has become the third-largest grocer in the United States by store count, trailing only Walmart and Kroger. When households at the top of the income distribution are trading down, the behavior has moved from necessity to norm.
The entire industry is reorganizing around this consumer. Walmart cut prices on ground beef, fresh corn, cherries, potato chips, and Coca-Cola this summer as part of a broader push to defend its price reputation. A May poll found that 61% of Americans had changed which groceries they bought to stay within budget. Beyond pricing, grocers are absorbing additional demand headwinds: reductions in food-stamp benefits and the growing use of weight-loss medications have led shoppers to buy less food overall, while elevated gasoline prices from the war with Iran have squeezed the same households from the other side of the budget.
The Second-Order Risk: Inflation Expectations Are Re-anchoring Higher
Here is the second-order question the market should be asking. The immediate grocery data is benign, but the expectations channel is flashing a warning. The University of Michigan's preliminary September reading of consumer sentiment fell to 47.8 from 51.7 in August, a 7.5% monthly drop and 13.2% below a year earlier. The expectations sub-index fell 11.1% in a single month, and current economic conditions dropped 15.7% from a year ago.
More strikingly, year-ahead inflation expectations jumped to 4.6% from 4.0%, the highest since June and well above the 3.4% seen in February before the US-led war with Iran began. Five-year expectations edged up to 3.4% from 3.3%, above their entire 2024 range of 2.8% to 3.2%. "With a resurgence in fuel prices and trade tensions, consumers anticipate greater pressures on their pocketbooks to come," said Joanne Hsu, director of the Surveys of Consumers.
Why does this matter for groceries specifically? Because expectations are self-fulfilling. If households believe prices will rise 4.6% over the next year, they pull spending forward, demand higher wages, and accept price increases more readily — which makes prices rise. The grocery aisle is ground zero for that loop because it is where inflation is felt most often. A stabilization in the food CPI does not break the loop if the belief that everything keeps getting more expensive keeps compounding.
This is the transmission mechanism that turns a grocery executive's observation into a macro signal. It is not that today's supermarket receipts are exploding. It is that the psychology they create feeds the next round of wage and price decisions. For the Federal Reserve, this is the difference between a victory lap and a last mile that keeps stretching: headline goods inflation can sit near target while the expectations channel quietly rebuilds the pressure the central bank was trying to extinguish.
The Counter-Thesis: This Is a Level Effect, and Sentiment Will Mean-Revert
The strongest case against reading too much into the pressure narrative is straightforward: food-at-home inflation at 2.2% is close to what the Federal Reserve would consider consistent with price stability, and the Agriculture Department expects 2.5% for the full year — slightly below the 20-year average. The pain is a level effect, the cumulative result of the 2021-2023 inflation surge, not evidence of a new inflationary regime. Once gasoline prices roll over and the labor market softens further, sentiment should recover on its own, just as it has after previous shocks.
There is real evidence for this view. Core goods inflation has been weak for much of the cycle. Used cars and trucks fell 2.3% over the year through August. Apparel rose 3.6% but has cooled from earlier peaks. New vehicles rose just 0.6% over the year. The monthly food-at-home index was flat in August. If the flow of prices is this calm, the pessimism looks like a lagging emotional artifact rather than a leading indicator — the tail of the inflation shock wagging long after the dog has stopped moving.
The counter-thesis is credible on the flow data. Its weakness is the expectations data. Sentiment can mean-revert, but only if the expectations channel breaks first — and at 4.6% for one-year-ahead inflation, it has not broken. It has moved in the wrong direction. A level-effect explanation accounts for why people feel poorer; it does not explain why they expect to get poorer faster next year.
What to Watch: The Falsifying Signal
The judgment that this is a durable behavioral shift with an embedded expectations risk can be tested. It fails if core goods inflation prints at or above 0.3% month on month for two consecutive months while Michigan's one-year inflation expectations hold at or above 4.5% into the final September and October releases. That combination would show that the disinflationary flow has stalled and the psychology has hardened — the opposite of the level-effect story.
Conversely, the pressure narrative weakens if one-year expectations fall back below 4.0% while food-at-home inflation stays near 2%, which would confirm that the pessimism was a transient reaction to energy prices rather than a structural reset. The final September sentiment release, due Sept. 25, is the first checkpoint.
Outlook: Three Horizons
Short term (sentiment and liquidity): The base case is continued strain. Gasoline prices, trade tensions, and a softening labor market keep the September sentiment read weak, and grocery traffic will keep rotating toward value formats through the holiday season. The upside case is a sharp drop in energy prices that pulls one-year expectations back under 4% and lifts sentiment into the fourth quarter. The downside case is expectations holding above 4.5%, which would pressure holiday spending across discretionary categories and force retailers to lean harder on promotions just when margins are already thin.
Medium term (fundamentals): Grocery retailers that can sustain price leadership — Aldi, Walmart, and hard-discount formats generally — keep taking share from traditional supermarkets. The Agriculture Department's category forecasts point to continued pressure in beef and veal and fresh vegetables, which will keep value messaging central to the consumer conversation. Retailers that cannot match price will lose basket share even if their margins are already thin. The winners will be those with the scale to absorb category shocks and the private-label depth to offer a cheaper substitute in every aisle.
Long term (structural): The behavioral change is the durable leg. Private-label penetration, discount-format adoption, and cross-income trading down are unlikely to fully reverse even in a low-inflation environment. Hart's "sticky growth" framing is the right read: the inflation shock converted temporary bargain hunters into permanent discount shoppers. That is a permanent redistribution of grocery market share, not a cyclical detour. The retailers built for a world of value-conscious, multi-format shopping will own the next decade; the ones built for the assumption that shoppers return to full-service baskets when inflation fades will not.
The Bottom Line
Aldi's US chief operating officer is right that Americans feel inflation pressure, but the reason is not the 2.2% grocery inflation rate on the latest report. It is that years of above-trend price growth have reset the price level, that salient categories keep delivering fresh shocks, and that households have responded by permanently rewiring how they shop. The inflation rate has cooled. The inflation scar has not.
