Petrol prices are starting to ease as oil slides back to the levels seen before the Iran war, unwinding a spike that hit drivers earlier this year. When the conflict began on 28 February, fuel costs jumped because the fighting disrupted the production and transportation of energy across the Middle East, a region central to global crude supply.

Why pump prices spiked in the first place

Crude oil is the single biggest ingredient in the price of petrol and diesel, so when supply looks threatened, wholesale costs climb fast. The outbreak of fighting raised fears that Middle East output and key shipping routes could be choked off, and traders priced in that risk almost immediately.

Oil markets are forward-looking, which is why prices can move on the threat of disruption long before any barrel actually goes missing. The Middle East accounts for a large share of global supply, and much of it moves through a handful of narrow maritime chokepoints, so even the possibility of interference is enough to send prices higher.

Those higher wholesale costs feed through to forecourts within days to weeks, which is why motorists felt the increase soon after the conflict started. Retailers buy fuel on the wholesale market and pass changes on to drivers, with a lag.

What falling oil means for drivers now

With oil back around pre-war levels, the upward pressure that pushed pump prices higher has largely faded. Lower crude usually filters down to cheaper petrol and diesel, although retailers are often quicker to pass on increases than reductions, a long-standing pattern sometimes called "rocket and feather" pricing.

  • Trigger: conflict beginning 28 February disrupted Middle East energy supply
  • Effect then: fuel costs jumped as production and transport were hit
  • Now: oil has returned to pre-war levels, easing the pressure on prices

The exact saving at the pump also depends on more than the crude price. Fuel duty and tax make up a large fixed share of the cost, the retailer's wholesale margin varies, and the strength of the pound against the US dollar matters because oil is traded in dollars. A weaker pound can blunt the benefit of cheaper crude, while a stronger one amplifies it.

Why it matters for households and the economy

Fuel is one of the most visible costs tied to global events, and changes at the forecourt are felt quickly by anyone who drives. Lower pump prices ease pressure on household budgets and can feed into broader measures of inflation, since transport costs ripple through the price of goods that have to be moved by road.

For businesses that run vehicles or rely on deliveries, the relief lowers operating costs and can help contain price rises elsewhere. For more on how energy and commodity swings ripple through the wider economy, see our business news coverage, and follow the latest updates in the newsroom.

What comes next for petrol prices

If crude stays near current levels, drivers should see the recent relief hold, though the savings may arrive at the pump more slowly than the increases did. The bigger risk is geopolitical: any fresh disruption to Middle East supply could quickly send wholesale costs, and forecourt prices, climbing again. Currency moves and changes in global demand will also shape how much of the cheaper crude actually reaches drivers.

Petrol prices and oil: quick FAQ

Why did petrol prices rise after 28 February?

The Middle East conflict that began on 28 February disrupted energy production and transport in a region central to global oil supply, pushing wholesale crude costs up, which fed through to the pumps within days to weeks.

Will lower oil prices reduce what I pay at the pump?

Usually yes, but with a lag. Retailers tend to pass on increases faster than cuts, and the final price also depends on fuel duty, retailer margins, and the strength of the pound against the dollar.
