The ongoing war between Iran and Israel is beginning to ripple through the UK economy, affecting everything from fuel prices to mortgage rates. As the conflict escalates, consumers may find themselves facing higher bills and altered financial landscapes. The ultimate impact will depend on the duration of the hostilities and the resilience of global supply chains.
Fuel Prices on the Rise
Motorists across the UK are already feeling the pinch at the petrol pumps. Recent data shows that average petrol prices have surged to an 18-month high of 140.6p per litre, marking an increase of nearly 8p since the onset of the conflict. Diesel prices are not far behind, climbing almost 17p to reach 159.2p per litre, according to the RAC.
This spike in petrol prices has sparked tensions between retailers and the government, with accusations of “profiteering” flying as a meeting took place to discuss the issue. Analysts have indicated that for every $10 increase in the price of oil, fuel costs at the pump typically rise by approximately 7p per litre. If oil prices remain elevated, we could see average petrol costs soaring to around 150p per litre in the near future.
While fuel supplies remain stable, motoring organisations are urging drivers to reconsider non-essential journeys and adopt more fuel-efficient driving habits, such as smoother acceleration and braking. However, the implications of rising fuel costs extend beyond drivers; increased transportation expenses for supermarkets could also lead to higher food prices.
Mortgage Rates Face Upward Pressure
In the realm of mortgages, the situation has taken a turn for the worse. Prior to the conflict, there was optimism surrounding a potential decrease in mortgage interest rates. Unfortunately, many of the UK’s major lenders have now raised their rates in response to escalating funding costs and the expectation that the base rate will not decrease as previously hoped.

As of the latest figures, the average rate for a two-year fixed mortgage has climbed to 5.10%, up from 4.84% earlier this month. Similarly, five-year fixed mortgage rates have increased from 4.96% to 5.19%, marking their highest levels since April. The uncertainty surrounding the economic climate has led lenders to withdraw over 500 residential mortgage products from the market, narrowing options for consumers.
Adam French, head of consumer finance at Moneyfacts, noted, “When lenders take the step of pulling deals rather than simply tweaking pricing, it often indicates that funding costs have moved too quickly for incremental changes to keep pace.”
Energy Bills and Heating Costs
Household energy bills are also in the spotlight, with some protections in place due to the price cap enforced by Ofgem in England, Wales, and Scotland. However, this cap is temporary and does not encompass all consumers. Currently, the maximum unit price for energy is set to remain unchanged until July, with predictions indicating a decrease in prices this April.
Nevertheless, the fluctuations in the wholesale energy market between now and late May will significantly influence household energy costs moving into summer. A prolonged period of elevated wholesale prices could lead to substantial increases in bills for millions of households. During the last spike in energy prices, which followed Russia’s invasion of Ukraine, the government had to intervene with the Energy Price Guarantee.
Energy Secretary Ed Miliband has stated that the government is prepared to act again if necessary, depending on the conflict’s impact. For those relying on heating oil, the situation is more precarious, as prices have reportedly doubled since the conflict began, with panic buying exacerbating shortages. Chancellor Rachel Reeves has promised a support package for households affected by rising heating oil costs, with further details expected soon.
Inflation and Interest Rates: The Bigger Picture
In early March, forecasts suggested that UK inflation would remain around the Bank of England’s target of 2% over the next five years. However, the recent military actions in Iran have thrown these predictions into disarray. Analysts now believe it is increasingly unlikely that inflation will remain contained, although they do not foresee a return to the peak of 11.1% experienced in October 2022.

The Bank of England’s primary tool for controlling inflation is adjusting interest rates. Following a committee meeting in February, Governor Andrew Bailey hinted at the possibility of further cuts. However, the current geopolitical tensions have shifted expectations, and analysts are now sceptical about any imminent rate reductions.
While borrowing costs may rise, there could be some benefits for savers as interest rates on savings accounts may become more attractive. Yet, the overall economic uncertainty may lead to reduced spending power, potentially hindering broader economic growth in the UK.
The Cost of Leisure: Travel and Entertainment
The ramifications of the Iran conflict stretch beyond essential costs, potentially impacting leisure spending. With rising fuel prices, holidaymakers may find their choices for spring and summer travel more limited, as flights become more expensive. Jet fuel prices have surged, and although airlines employ hedging strategies to mitigate these costs, prolonged high fuel prices will inevitably be passed on to consumers through increased fares.
Why it Matters
The ongoing conflict in Iran has significant implications for the average consumer in the UK, from rising costs at the petrol pump to increased mortgage rates and sky-high energy bills. As global economies grapple with the fallout from geopolitical tensions, households may find their financial well-being under strain. Understanding these shifts is crucial for consumers as they navigate the evolving landscape of costs and make informed decisions about their finances in uncertain times.
