Are Rising Food Costs Cracking Global Supply Chains?

Food prices in the UK are continuing to climb and the knock-on effect is running deep through the supply chain.

Shoppers face more expensive staples like eggs, chocolate and butter, while retailers and manufacturers scramble to adjust operations.

The British Retail Consortium (BRC) has reported food inflation at 4.2% in the year to August, up from 4% in July, marking the steepest rise since February of last year.

The figures mirror similar data from the Office for National Statistics (ONS), which found the price of daily essentials is following the same upward path. 

Helen Dickinson, Chief Executive of the BRC, explains: “Staples including butter and eggs have seen significant increases due to high demand, tightening supply and increased labour costs.”

The sharp climb in cocoa prices, driven by poor harvests and climate impacts, also feeds through to chocolate costs.

“Chocolate also got more expensive as global prices of cocoa remain high owing to poor harvests,” she says.

Farms under pressure

The pressures begin at the source. Cocoa, eggs and dairy have all faced disruptions that ripple outwards. Climate change and disease hurt cocoa yields, cutting global supply just as demand holds firm.

For egg producers, livestock feed inflation and disease outbreaks like bird flu mean supply is tight, with little slack in the system. Such issues affect the upstream supply chain, the part responsible for raw material production and sourcing.

When cocoa crops fail or poultry populations drop, the impact spreads fast. Unlike some manufactured goods, many food items can’t rely on substitutions. You can’t easily replace eggs or butter in baked goods without complex reformulations, which add regulatory and logistical complications.

This gives ingredient producers more bargaining power. Demand for core ingredients stays steady, so when supply dips, buyers have little choice but to pay more. Farmers and producers, particularly of essentials like dairy and eggs, find themselves with leverage they rarely enjoy.

Choices narrow and margins tighten

The next link in the chain is food manufacturing and, here too, pressure builds. Food producers face difficult decisions between absorbing rising costs or passing them on to retailers. 

Many opt to rationalise their offerings, focusing on fewer products and limiting variety. Chocolatiers, for instance, may drop certain lines if ingredients become too expensive. Retailers, bakeries and cafés start to offer “streamlined” ranges, reducing options for consumers.

Labour and energy remain major expenses and, combined with supply constraints, many manufacturers lose the flexibility to adapt quickly. Without the ability to pivot, even a slight shift in costs or supply can cause disruption.

Mike Watkins, Head of Retailer and Business Insight at NIQ, which helps compile the BRC’s shop price monitor, outlines the broader picture: “The uptick reflects several factors.” 

Retailers then try to absorb or repackage these pressures. Supermarkets juggle rising supplier costs with price-sensitive customers. One tactic is leaning on non-food promotions.

Shrinkflation and trading down also affect this end of the chain, as branded goods lose ground to private label alternatives, while pack sizes shrink. Demand becomes harder to predict, making inventory management trickier and pushing more volatility into the system.

Can science stabilise supply?

Food companies are also investing in long-term resilience. With cocoa prices driven higher by drought, ageing trees and disease in West Africa, where 70% of global cocoa is grown, some firms are turning to science.

Mars, the maker of Snickers and M&M’s, is backing CRISPR gene-editing technology through a licensing deal with agricultural biotech firm Pairwise. The partnership aims to develop cocoa plants that are more resilient to climate and disease pressures.

Pairwise’s platform, known as Fulcrum, enables researchers to identify and edit genetic traits that make crops hardier and more adaptable.

Hershey, another chocolate giant, has also responded by reducing its reliance on cocoa, focusing instead on ingredients like peanut butter and wafers. Lindt, meanwhile, admits that demand is slipping as prices stay near record highs. 

While such innovations offer hope, they are no quick fix. Developing new crop varieties takes time, and scaling them for global markets adds cost and complexity.

In the meantime, the fragility of the food supply chain remains clear - from the farm, through production lines, to the supermarket shelf.
