Oil prices have surged nearly 9% in 24 hours after US and Israeli strikes on Iran escalated into an active military conflict over the weekend. Brent crude jumped from $72.87 to above $79 per barrel — the sharpest single-day move in over a year. For UK drivers, the question is simple: will this hit the pumps? The short answer is not yet — but it will if the conflict continues.
What's happened to oil prices
The numbers moved fast over the weekend:
Brent crude — the international benchmark that directly influences UK fuel prices — was trading at $72.87 on Friday. By Monday morning it had hit $79.41, a jump of nearly 9%. US crude (WTI) followed the same trajectory, climbing from around $67 to $72 per barrel.
The trigger: US and Israeli military strikes on Iran over the weekend, followed by Iranian retaliatory strikes across the region. The conflict is now in its third day with no sign of de-escalation.
Why the Strait of Hormuz matters
The real driver of oil market panic isn't the conflict itself — it's the Strait of Hormuz. This narrow waterway between Iran and Oman is the most important oil chokepoint on the planet:
- Around 15 million barrels of crude oil pass through it every day
- That's roughly a third of all seaborne oil trade worldwide
- Oil from Saudi Arabia, Kuwait, Iraq, Qatar, the UAE, and Iran all flows through it
- It's also a critical route for liquefied natural gas (LNG) exports, particularly from Qatar
Since the conflict began, tanker traffic through the strait has slowed dramatically. Marine tracking sites show vessels piling up on either side, with shipping companies unable or unwilling to get insurance for the passage. Iran has declared the strait closed — though whether it can enforce a full blockade remains unclear.
If the strait stays disrupted for weeks rather than days, analysts have warned oil could top $100 per barrel. That's the scenario that would cause serious pain at the pumps.
What this means for UK petrol prices
Here's the important bit: fuel prices don't rise overnight. There's a lag between oil markets moving and that change reaching UK forecourts. Here's how the timeline typically works:
Right now, the average UK petrol price sits around 131.9p per litre. Industry analysts are predicting a return to at least 135.7p — the level seen at the start of 2026 — if the disruption continues. A prolonged closure of the Strait of Hormuz would push prices significantly higher.
Why Europe is more exposed than the US
Since cutting off Russian oil imports, Europe has become heavily dependent on Middle Eastern crude shipped through the Strait of Hormuz. The US is in a comparatively stronger position — it secured access to Venezuelan oil reserves in recent weeks, reducing its reliance on the strait. That means UK and European drivers are likely to feel the impact more acutely than American motorists if the disruption drags on.
Should you panic-buy fuel?
No. The UK has adequate fuel stocks right now. The fuel in petrol station tanks, pipelines, and storage depots was purchased before this weekend's price spike. There is no immediate supply shortage.
The risk, as always, is that panic-buying creates the shortage it fears. We've seen this before — media reports of potential price rises trigger a rush to fill up, which depletes forecourt tanks and creates artificial scarcity. Don't be part of the problem.
That said, if you were already planning to fill up this week, there's no harm in doing it sooner rather than later. Prices today reflect last week's oil costs. Prices in two weeks will reflect today's.
What to watch for
The situation is evolving rapidly. Here are the key indicators that will determine whether this becomes a short-lived spike or a sustained price increase:
- Strait of Hormuz status — if tanker traffic resumes within days, prices will settle. If Iran maintains a blockade, expect $90+ oil
- Conflict duration — a ceasefire or de-escalation would see oil prices retreat quickly. Continued strikes keep the risk premium high
- OPEC response — Saudi Arabia and other Gulf states could increase production to offset disruption, but only if their exports can actually leave the Gulf
- UK wholesale prices — watch for movements in the platts benchmark over the next 7–10 days. That's what determines what retailers actually pay
How to protect yourself from rising prices
You can't control geopolitics, but you can control where you fill up. The difference between the cheapest and most expensive station in the same area is routinely 10p per litre or more — and that gap tends to widen during periods of price volatility, as some retailers raise prices faster than others.
- Compare before you fill — use Fuelwise to find the cheapest fuel near you. When prices are moving, the savings from shopping around increase
- Supermarkets are usually cheapest — Asda, Tesco, Sainsbury's, and Morrisons typically price below branded forecourts, especially during volatile periods
- Avoid motorway services — the premium over local stations can be 15–20p per litre
- Don't brim your tank unnecessarily — fill up normally when you need to. Hoarding fuel in jerry cans is unsafe and counterproductive
- Drive efficiently — smooth acceleration, proper tyre pressures, and removing roof boxes can improve your MPG by 10–15%, stretching every tank further
Understanding the price chain
Wondering why crude oil at $79 per barrel translates to 132p per litre at the pump? Over half of what you pay is tax. Our guide to how UK fuel prices are set breaks down exactly where your money goes — and why a $6 rise in oil doesn't mean a 6p rise at the pump.
The bottom line
UK fuel prices aren't spiking today. But the conditions for a meaningful increase are now in place. Oil is up nearly 9%, the Strait of Hormuz is disrupted, and Europe is particularly exposed. If the Iran conflict continues beyond the next few days, drivers should expect petrol prices to climb back toward 135–140p per litre within two to four weeks. If it escalates further, all bets are off.
The best thing you can do right now is stay informed, avoid panic-buying, and make sure you're not overpaying at the pump. Check your local area on Fuelwise to see who's cheapest today — because when prices start rising, the stations that were already expensive become even harder to justify.
