Against the backdrop of persistently high input costs, a quiet but consequential economic phenomenon is reshaping supermarket shelves: shrinkflation. The practice, whereby product sizes are reduced while prices remain unchanged, has moved from a niche concern to a subject of open public debate, especially after a major French retailer began flagging it for shoppers in 2023. The term itself is a portmanteau of “shrink” and “inflation,” coined as the counterpart to traditional inflation, where prices rise while the product stays the same.
Its first recorded use in this modern sense is attributed to economist Pippa Malmgren, although historian Brian Domitrovic had earlier used the word to describe a wider economy contracting while suffering high inflation. A related practice, skimpflation, involves reformulating products or reducing their quality rather than shrinking quantity.
Why companies shrink, not raise
The economic logic behind shrinkflation is straightforward. By reducing pack size, manufacturers and retailers can manage rising production costs while maintaining sales volume, operating margin, and profitability, often as an alternative to raising prices when customers are price-sensitive. But the practice has a peculiar effect on official inflation measures.
Shrinkflation sometimes does not affect headline indices such as the Consumer Price Index or Retail Price Index, but many price level indicators linked to units of volume or weight do capture shrinkflation within statistically represented inflation figures.
Consumer criticism and stealth reductions
Consumer protection groups have been sharply critical. They argue that shrinkflation reduces product value “by stealth” — the reduction in pack size is deliberately small enough to escape immediate notice from regular shoppers, thereby undermining informed buying choices. Studies have shown that consumers are more deterred by outright price rises than by pack size reductions; in fact, some prefer a smaller package at the old price over the old size at a higher price.
What is at stake, say advocates, is not just pocketbook economics but transparency in the marketplace. Ratula Chakraborty, a professor of business management, has argued that suppliers and retailers should be legally obliged to notify shoppers when pack sizes are reduced.
Carrefour’s warning labels
In 2023, the French grocery chain Carrefour took an unusual step: it began warning customers about shrinkflation practices directly on store shelves. The move thrust the issue into the mainstream and put pressure on multinational brands to justify downsizing. The wider picture is that shrinkflation operates as a stealth inflation tax on households, one that economists sometimes defend as rational but critics call deceptive.
As households continue to grapple with the cost-of-living squeeze, the debate over whether regulators should step in is likely to intensify.
