Sticky Prices in Retail Fuel - What Goes Up Doesn't Always Come Down!

Graham Watson

6th January 2023

The petrol sector is under fire for proving Keynes right about sticky prices. Although petrol and diesel prices are falling, according to the RAC they're not falling fast enough. Wholesale prices have fallen but whereas the average price of petrol is now 151p per litre and the average price of diesel is 174p, they think it should be 140p and 160p.

Given that the Competition and Markets Authority are already looking at whether petrol retailers passed on cuts in fuel duty to consumers, and their initial assessment identified so-called 'rocket and feather' pricing, you'd have to wonder what it is that stops prices from falling. Unless, of course, you're John Maynard Keynes and you've identified that it's in company's interests to keep them high, if they can.

And, think, how might the market structure increase the likelihood of prices remaining high?
