During latest months, a story has been pushed by some politicians and trades unions of ‘greedflation’, the notion that inflation is being brought on by companies plumping up their revenue margins on the expense of customers.

One of the sectors accused of doing this, by the Liberal Democrat chief Sir Ed Davey amongst others, was grocery retail – although a cursory examination of the accounts of most supermarkets urged there was little or no proof of that really being the case.

So it was no shock to see the Competition & Markets Authority (CMA) so categorically debunking the myth of greedflation in meals retailing right this moment.

In truth, because the CMA makes fairly clear, competitors within the sector is so intense that the supermarkets have been unable to cross on their larger prices to consumers.

The CMA factors out that working earnings within the retail grocery sector throughout 2022-23 have been down 41.5% on the earlier 12 months and that common working margins within the sector fell from 3.2% to 1.8%. Put one other means, for each £100 of gross sales, the everyday grocery store is making a revenue of simply £1.80.

In different phrases, the CMA has concluded that consumers are getting a reasonably whole lot. This discovering is a serious end result for the supermarkets.

The query is why the CMA – and all of the retailers it quizzed as a part of this investigation – was obliged to provide this report within the first place.

It has been completely apparent to anybody with even a passing acquaintance with the grocery retail sector that there was no difficulty with competitors within the sector. The CMA itself stated that when, in May, it stepped up its work on grocery costs.

The reply, in fact, is that this investigation was foisted on the CMA by a authorities determined to be seen to be doing one thing to mitigate the cost of living crisis.

There was no want for this investigation and all it has executed is devour a great deal of time and power each for the CMA itself and for the grocery store business.

That is to not say that the broader food and drinks business is out of the woods.

The investigation into the supermarkets has drawn consideration to the working margins of what was referred to as ‘Big Food’ – the likes of Mars, Nestle, Unilever and Mondelez – and the way a lot greater they’re than these of the supermarkets.

Now that the CMA has determined to broaden its investigation to “the wider grocery supply chain”, in its phrases, a few of these firms can be watching with unease.

It is very attention-grabbing that the CMA can be going to look into extra depth at 10 particular product classes, amongst them bread, milk and child components.

The watchdog’s findings on milk can be particularly attention-grabbing.

Milk is a value class that for a few years has been used as a ‘loss chief’ by restricted assortment German discounters, Aldi and Lidl, to get individuals into their shops. That has obliged the normal ‘massive 4’ – Tesco, Sainsbury, Asda and Morrison – to do likewise on events and, when it has occurred, dairy farmers have suffered.

The latter can be notably anxious to get their views throughout to the CMA.
