d it didn’t see shoppers pulling back in March. But it also flagged that the latest jump in energy prices could raise operating costs – and, with a lag, push up shelf prices across its markets.

Why should I care?

For markets: Thin margins leave little room for surprises.

Supermarkets run on high volume and low profitability, so cost spikes matter fast. Carrefour’s profit margin was 2.6% last year, down from 3.1% in 2021, which means there’s less buffer to absorb pricier power, transport, and cooling. If those costs stay elevated, retailers either eat the hit to protect market share or pass it on and risk slower demand – a bigger challenge in Brazil, where high rates are already straining household budgets.

The bigger picture: Energy can sneak back into inflation.

Even if food inflation looks calm in France today, higher energy prices can quietly work their way through supply chains, from factories to delivery trucks to store refrigeration. That can make “essentials” inflation stickier than expected, which central banks watch closely. If it stays sticky, interest rates can remain higher for longer – and that typically weighs on consumer spending, making it harder for retailers to grow volumes.
