The ongoing conflict between the US and Israel on one side and Iran on the other is beginning to ripple through the UK economy, affecting everything from fuel prices to mortgage rates. As the situation evolves, consumers are facing increased costs that could linger long after the fighting subsides. Here’s a closer look at the areas most likely to be impacted and what that means for everyday expenses.
Fuel Prices on the Rise
Motorists have likely noticed an uptick in fuel costs recently. As of Sunday, the average price of petrol rose by 4.68p to £1.3751 per litre, while diesel saw a more significant jump of 8.59p, reaching £1.5097. Analysts indicate that a $10 surge in oil prices typically translates to an increase of around 7p at the pump. Since the onset of the conflict, crude oil prices have soared over $30, suggesting that average petrol prices could soon exceed £1.40 per litre, with the possibility of breaching £1.50 if oil prices remain high.
While there are currently sufficient fuel supplies, organisations like the RAC are urging motorists to limit non-essential journeys and adopt driving habits that conserve fuel, such as avoiding sharp acceleration and braking. Even for those who do not drive regularly, rising petrol costs can lead to increased prices for goods and services as transport costs climb. For instance, if supermarkets face higher transport expenses, this could subsequently drive up the price of food.
Mortgage Rates and Financial Choices
Before the conflict erupted, there was optimism surrounding a gradual decline in interest rates for both fixed and variable mortgages. However, the current situation is reversing that trend. Major lenders have begun increasing rates due to rising funding costs and a prevailing expectation that the base borrowing rate will not decrease as previously anticipated.

As of now, the average rate for a two-year fixed mortgage has climbed to 4.87%, while a five-year fix stands at 4.98%. These rates are reminiscent of levels not seen since August of last year. Economic uncertainty often leads lenders to withdraw mortgage products, reducing options for consumers. Some lenders have already suspended their offerings, anticipating a need to increase prices further. 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.”
The Impact on Energy Bills
For households, energy bills are currently buffered by a price cap set by Ofgem, the energy regulator in England, Wales, and Scotland. This cap, however, is temporary and does not encompass all consumers. The pricing for variable energy deals governed by the cap is secure until July, with prices expected to decrease in April. Nevertheless, the outcome of wholesale energy market trends over the coming months will significantly influence future household energy costs.
If wholesale prices remain elevated, millions could face steep increases in their energy bills come summer. During previous crises, such as the fallout from COVID-19 and Russia’s invasion of Ukraine, the government intervened with initiatives like the Energy Price Guarantee. Those looking to fix their energy tariffs now face a challenging landscape, with many providers withdrawing offers or setting higher prices. Rural residents relying on heating oil are feeling the most immediate impact, as prices have more than doubled since the conflict began, exacerbated by panic buying and limited supply.
Inflation and Interest Rates: A Changing Landscape
At the beginning of March, UK inflation was projected to align with the Bank of England’s target of 2% over the next five years. However, this forecast was made before the escalation of hostilities. Analysts are now concerned that the conflict could hinder these predictions, making accurate inflation estimates increasingly complex.

While experts do not foresee inflation reaching the peak of 11.1% observed in October 2022, the current geopolitical turmoil complicates the economic landscape. The Bank of England, responsible for managing inflation, may find it challenging to lower interest rates as anticipated. Analysts who previously expected rate cuts in March have since revised their outlook, suggesting borrowing could become more expensive. Conversely, savings may yield slightly better returns as consumers typically increase their savings during uncertain times. However, this could diminish purchasing power if inflation rises, ultimately stunting economic growth.
The Broader Economic Implications
The ramifications of the Iran conflict extend beyond immediate price increases, influencing consumer choices and economic stability. As travel costs soar due to rising jet fuel prices, holiday options for consumers may become more limited. Airlines, while employing strategies to mitigate costs, will likely pass on some of these increases to passengers if fuel prices remain high.
The economic landscape is shifting, and while it’s difficult to predict the long-term consequences of the conflict, it’s clear that consumers will need to navigate a more turbulent financial environment.
Why it Matters
The ongoing conflict in Iran serves as a stark reminder of how global events can have immediate and profound effects on local economies. As fuel, mortgage, and energy prices rise, consumers are faced with difficult financial choices that could alter their spending habits and overall economic well-being. Understanding these dynamics is crucial for individuals looking to manage their finances effectively in these uncertain times. The implications of this conflict are not just geopolitical; they directly impact our daily lives and the choices we make about our finances.
