Petrol prices break 140p a litre as Iran war energy shock hits Brits at the pump

My reaction is that this is exactly the kind of cost shock households do not need, because petrol is not a luxury for a lot of people, it is how they get to work, do the school run and keep life moving. Once fuel pushes through levels like this, people feel it immediately. If the war keeps oil markets under pressure, I would not rule out petrol moving further into the mid-140s, and diesel staying painfully elevated too. Brent crude has jumped above $100 a barrel again on supply fears linked to the conflict, which is why this matters beyond the forecourt. The inflation risk is real because higher fuel costs feed straight into transport, delivery and everyday business costs. UK CPI was 3.0% in January and Bank Rate is 3.75%, with the next BoE decision due on 19 March. If energy pressure persists, hopes for smoother rate cuts could fade very quickly.

The jump to 140.28p for petrol and 158.78p for diesel marks a painful "energy shock" for Brits, and prices could climb much higher. Analysts warn that if oil hits $100 per barrel, petrol may reach 150p; at $120, it could soar to 170p. This is incredibly tough for motorists, especially those in rural or car-dependent roles, with an average driver potentially facing over £320 in added annual costs. The economic ripple effects are severe. The OBR predicts this spike could add 1% to inflation, pushing it toward 4% and beyond, and stalling the recovery we all so desperately need. Consequently, the Bank of England is expected to halt planned interest rate cuts, likely holding the base rate at 3.75% this March to prevent a price spiral with a growing possibility of a rate rise back up to 4% if the conflict persists. This shift has already caused mortgage rates to creep back above 5%, further tightening the squeeze on household budgets.

The Iran conflict is not creating an entirely new problem so much as accelerating an existing one: oil, was already structurally underpriced, and any disruption in the region simply brings forward a sharper repricing. I would not view 140.28p a litre as a ceiling. If disruption to shipping routes and energy flows persists, petrol and diesel could move materially higher from here because the issue is not merely sentiment but the physical availability, movement and refining of oil and its by products. The wider inflation impact could be significant. Oil is embedded in vast parts of the economy, directly and indirectly. It affects haulage, food distribution, manufacturing, farming, deliveries and general transport costs. So dearer fuel does not simply mean a more expensive trip to the petrol station; it also feeds into supermarket prices, services and overall living costs. In that sense, higher petrol and diesel prices can act as a broad inflation amplifier.

War is one of the most expensive things a society can do and when the war affects oil, it's going to push up the price. There's no obvious end to this conflict and so i'd expect prices to remain elevated and may even go higher. If it stays high then it could start feeding into higher inflation as oil is such an important industrial input.
