Oil prices have surged since the conflict in the Middle East disrupted shipping through the Strait of Hormuz in late February. That matters because it touches almost everything you spend money on, from filling your car to your weekly shop. Here is what it means in practice and what you can do about it.
How does the oil crisis affect me?
Higher oil prices push up the cost of fuel, energy, and food. Since February 2026, petrol has risen to around 157p per litre and diesel to 188p, adding roughly £14 to a typical family car fill-up. Grocery prices could rise as much as 10% by year-end as transport and packaging costs filter through supply chains.
What is driving the price spike?
Brent crude jumped from about $73 to over $126 a barrel after the Strait of Hormuz, a chokepoint for roughly 20% of global oil, was effectively closed. Until shipping normalises, prices are likely to stay volatile. Every $10 rise in oil adds around 7p per litre at the pump.
The knock-on effects you will feel
Fuel. The most immediate hit. If you drive 10,000 miles a year, you could be paying an extra £500 to £700 annually compared with January.
Energy bills. Gas and electricity are linked to wholesale energy markets. The April 2026 price cap already reflected some of the increase, and further rises are possible if oil stays above $100.
Food. Supermarkets rely on long supply chains. Higher diesel costs mean higher delivery costs, and those get passed on. The Food and Drink Federation has warned of meaningful grocery inflation later this year.
Inflation and interest rates. UK CPI hit 3.3% in March, with fuel the biggest upward contributor. If inflation stays sticky, the Bank of England may hold rates higher for longer, which affects mortgage costs and borrowing.
What about your investments?
Short-term volatility is normal during supply shocks. Energy stocks tend to benefit, but broad markets can dip as consumer spending tightens. If you are investing for five years or more, the house view is to stay the course. Selling during a spike usually locks in losses rather than avoiding them.
What you can do
Review your budget. Fuel and grocery spend may have crept up without you noticing. A quick check now can stop small leaks becoming big ones.
Top up your emergency fund. If rising costs are eating into your margin, having three to six months of essential spending in cash gives you breathing room. See our guide on how much emergency fund you need.
Don't react with your portfolio. Rebalance if your risk profile has genuinely changed, but avoid making emotional moves based on headlines.
Check your plan. If higher bills or mortgage costs are shifting your priorities, it is worth revisiting your financial plan to see what still works and what needs adjusting.
