The momentum had been gathering for some time. And at the appropriate moment RMI Petrol made its submission to the Office of Fair Trading (OFT) for an inquiry into the UK fuels market. It must respond within 30 days.

The OFT submission followed a month in which supplies were disrupted through tanker driver strike action, and the well-publicised problems at the Coryton refinery in Essex; the AA launched an app showing motorists how to drive using less fuel another nail in the coffin for fuel retailers. And then bam, diesel prices hit a record high, having rocketed by 10ppl in just 12 months an inflation-busting 7% rise.

"The increase leaves diesel at 143.05ppl, a level that could derail government plans to curb inflation, is a disaster for motorists, and puts the livelihoods of hundreds of fuel retailers at further risk," said RMI Petrol chairman Brian Madderson.

Madderson predicts more grim news ahead as a ’perfect storm’ of global factors including rising crude oil prices, closing refineries and pressure on supply, mean that by Easter diesel and petrol prices are likely to go even higher.

Inflation for diesel is now almost double that of the Consumer Price Index (CPI) of 3.6%. Madderson believes the coming March Budget is the ideal opportunity for Chancellor George Osborne to cut the rate of duty on fuel, as he did last year. Madderson has also called on thegovernment to ease the pressure on motorists and the economy by ditching plans to raise fuel duty by 3.02ppl from August 1, 2012. Such a rise would result in a 4ppl price hike once VAT at 20% is included, according to Madderson. "It’s all very well for the government and Bank of England to declare that CPI is heading down, but try telling that to cash-strapped retailers and to the millions of motorists, truckers and van drivers now paying an average 143.05ppl for their diesel," he said. "We’re seeing runaway inflation for diesel; petrol is little better."

RMI Petrol has become so concerned that after months of intensive evidence gathering it made a formal submission to the OFT recommending that it conduct an urgent new study into the UK fuels market.

Madderson said: "This record price for diesel, plus the rising costs of petrol, means household budgets, big business and small and medium sized operators are all being squeezed by these high fuel prices. Our economic recovery seems to have stalled and government must resist the temptation to hike fuel tax.

"We have not seen prices like this since the record was set on May 9, 2011, during the ’Arab Spring’ uprisings when diesel hit 143.04ppl. RMI Petrol had warned government that this worrying price rise was inevitable and now it is with us. It must cast serious doubt over any hope of the government hitting its 2% inflation target by the Autumn."

Worse still, with diesel now accounting for 55% of UK retail and commercial road fuels, RMI Petrol believes there is no respite as petrol costs are also on the rise, 5% up on February 2011 (though the average at 135.09ppl for petrol is short of the May 2011 record of 137.43ppl).

RMI Petrol’s report to the OFT calls for an immediate investigation into the UK fuels market under the Enterprise Act:2002. Madderson said: "Business and consumers deserve the truth about the costs and pricing of such a vital commodity.

"Alleged unfair pricing and predatory pricing tactics by certain hypermarkets and oil companies are driving independent operators out of business at the rate of 250 to 300 sites a year. This death of the independent fuel retailer will lead to higher prices and a loss of refuelling facilities, particularly in our rural areas.

"This will be the most important study of the troubled UK fuels market for more than a decade. Rising pump prices show no sign of abating. Now more than ever it is absolutely crucial that the OFT obtains real transparency into the structure of wholesale costs and retail competition. We would welcome, as we know many MPs would welcome, swift action by the OFT to progress this study."

RMI Petrol says pressure on pump prices will continue to grow. Goldman Sachs predicts that Brent Crude will push through the US$120/barrel barrier within three months due to greater global demand and production shortages across Europe.

Several refineries remain for sale and others have closed either for extended maintenance or due to lack of profitability, all of which puts more pressure on supply and retail prices.

highlights of the 1998 OFT report

The 1998 report by the Office of Fair Trading focused on the following key indicators: structure, prices, and profitability. In reviewing competition within the market, the OFT also considered whether there was any evidence of: predatory behaviour, collusion, or exclusionary behaviour, and whether any of these types of behaviour were likely to occur in the future. Included in its four recommendations, it proposed to: continue to monitor the industry with the objective of continually assessing the state of competition within it so that any market failure could be detected and acted upon promptly; examine carefully any further UK refinery consolidation or refiner joint ventures to ensure non-refining wholesalers and supermarkets could continue to obtain competitively-priced supplies based on Rotterdam prices; ask the Valuation Office to give consideration in the review of business rates to adjusting them for petrol retailers so they are proportionate to turnover in the supply of petrol, thus removing the favourable position of supermarkets.
