CMA orders data handover

The UK Competition and Markets Authority (CMA) announced it is increasing monitoring of petrol and diesel retailers and has formally “put on notice” firms that run thousands of filling stations, telling them to expect stricter scrutiny amid concerns of profiteering as the US war with Iran pushes up wholesale costs.

The watchdog said it will require firms to hand over revenue, costs and sales data and is accelerating a review of fuel industry margins it began shortly after the conflict started.

This action forms part of a wider government crackdown intended to prevent companies from “ramping up profits at the expense of consumers.”

Energy market volatility

The CMA move is set against sharp volatility in global energy markets triggered by Iranian attacks on regional energy infrastructure and threats to the strait of Hormuz, which helped push the oil price above $100 a barrel for a second time in a week despite a large release of government reserves.

The Guardian described the backdrop as volatile and linked the price jump directly to widespread Iranian attacks and the strategic risk to shipping routes that underpin global supply.

Consumer price rises

Consumers are already feeling the impact: petrol and diesel prices have risen sharply, and the RAC reported an average petrol price increase of 5.5% (about 7p per litre) and an average diesel price increase of 11.1% (nearly 16p) since the bombing of Iranian targets began.

The Guardian also flagged a simultaneous jump in home heating fuel costs, reinforcing concerns that household energy bills will rise alongside pump prices.

Political and economic risks

Political figures and economic analysts warned of broader economic consequences: Rachel Reeves said the government would not tolerate companies exploiting the crisis for “excess profits” and she would ask the CMA to heighten its vigilance.

Experts cited in the piece warned a sustained rise in global oil and gas prices would lift inflation in Britain, undermining hopes that the Bank of England could cut interest rates at its next meeting.
