For investors, what does shrinkflation mean?

For consumers, shrinkflation is more than just a nuisance

According to James Mackreides, it may be a precursor to a company's declining capacity to raise prices publicly.

Shrinkflation is common. The gap at the top is not an optical illusion; Pringles' manufacturers narrowed the canister and reduced the contents from 200g to 165g while the price increased toward 2.25. When was the last time you opened a tube of Pringles and saw the crisps reaching the foil seal? The price per gram increased by 118% as a result.

Although consumers may notice fewer crisps, shrinkflation affects more than just them. It may be an early warning that a company's capacity to raise prices publicly is starting to deteriorate, so investors should see something more telling.

The phrase "shrinkflation" was first used in 2009 by economist Pippa Malmgren to characterize the practice of shrinking a product while maintaining or even raising its headline price. Manufacturers use a simple behavioral quirkshoppers notice the price on the shelf far more readily than the net weight printed on the packagingto subtly trim the contents rather than risk the backlash of an overt price increase. It has emerged as one of the key reactions to the inflationary period, assisting consumer goods firms in protecting their profit margins while averting the shock of price increases.

Manufacturers frequently resort to "skimpflation"substituting less expensive ingredients for more costly oneswhen cutting pack sizes runs the risk of being too obvious. Morrisons has decreased the amount of beef in its ready-meal lasagna, and Tesco has decreased the amount of pork in its Finest sausages from 97% to 90%. Although the cost of producing the goods decreased, the prices hardly changed.

Why do businesses use shrinkflation rather than price increases?

Investors wonder why businesses use these strategies. Since consumers value the product enough to want to pay more, companies with real pricing power are typically able to raise prices openly. Businesses that cater to more cost-conscious customers have fewer choices. Instead of clearly raising prices to gage demand, they shrink or skimpflate. This is known as "pack architecture optimization" or "revenue growth management" according to executives. When traditional pricing power is under pressure, investors should see it as an attempt to preserve margins.

Both psychology and economics contribute to the strategy's effectiveness. In general, consumers are more sensitive to price changes that are displayed on the shelf than they are to minor weight or volume reductions. Asymmetric price perception is how behavioral economists characterize this. Manufacturers can temporarily recoup higher input costs through shrinkflation without running the risk of the precipitous decline in demand that frequently follows an outright price increase. There are limits to the strategy. When applied sparingly, it can help protect margins in times of exceptionally high inflation. When used frequently, it runs the risk of eroding the brand value that formerly gave a business pricing power. It can take years to regain customers' trust once they start to doubt whether a reliable brand still offers good value.

Customers are more likely to move to private-label products that offer comparable quality at a lower cost if they believe they are consistently paying more for less. Companies that frequently use hidden price increases run the risk of educating consumers to shop elsewhere.

Fortunately for investors, listed companies seldom manage to permanently conceal the effects. Usually, the accounts contain the evidence. A more accurate picture of a brand's health can frequently be obtained by looking beyond headline revenue growth to the ratio of pricing to volumes. The point is further supported by Mondelez's financial results. At first glance, its 2025 organic net revenue growth of 4.3 percent seems respectable. A closer examination reveals that volume and mix decreased growth by 3.7 percentage points, while pricing contributed 8.0 percentage points. Although revenue was still increasing, fewer products were being purchased by customers. Nestl's reporting presents a comparable narrative. Although "real internal growth"a measure of physical demandremained negative, organic growth remained positive as rising prices countered rising costs.

This is relevant. Genuine pricing power is often indicated by strong pricing backed by consistent volumes. Strong pricing combined with ongoing drops in volume merits much more investigation. Smaller packs and higher prices can help businesses temporarily preserve profits, but declining sales could be a sign that consumers are starting to doubt the brand's worth.

A shifting landscape related to shrinkflation.

The circumstances that gave rise to shrinkflation are also shifting. Customers are becoming more conscious of the practice, retailers are focusing more on value perceptions, and authorities are facilitating price comparisons. Unit prices must be shown more consistently and clearly starting in April 2026 in the UK due to changes to the Price Marking Order. While UK supermarkets have continued to expand their own-label lines, French supermarket Carrefour has gone so far as to prominently display shrinkflation notices beneath impacted products during pricing disputes. When taken as a whole, these developments make it more difficult for manufacturers to rely on shrinking packs without drawing more attention.

The lesson for investors is not that shrinkflation should be avoided by all companies. Management teams occasionally have to make tough decisions due to commodity inflation, and small pack size reductions might be preferable to price increases that drive away customers. Whether shrinkflation is now a transient reaction or a long-term habit is the crucial question. Analyzing margins, cash flow, and valuation takes a lot of time for investors. They ought to pay equal attention to whether revenue growth is a reflection of consumers' willingness to pay higher prices or just the result of packs getting smaller and prices going up. Shrinkflation may be a useful indicator of the fundamental health of a business.
