The ongoing conflict involving Iran is beginning to have notable repercussions on the financial landscape in the UK, affecting everything from petrol prices to mortgage rates. As the situation unfolds, the extent and duration of these economic effects will largely depend on how long the conflict persists and how swiftly global supply chains can adjust. Here’s a closer look at the key areas that could influence your wallet.
Rising Fuel Prices: What to Expect at the Pumps
Motorists are already feeling the pinch, with petrol prices climbing to an 18-month high of 140.6p per litre as of Friday, marking an increase of nearly 8p since the onset of the conflict. Diesel prices have surged even higher, now averaging 159.2p, up by almost 17p. This spike has ignited a dispute between petrol retailers and the government, with retailers accusing officials of using “inflammatory language” regarding alleged profiteering amid rising oil prices.
Analysts suggest that for every $10 increase in crude oil, petrol prices can be expected to rise by roughly 7p per litre. The volatility in oil prices, driven by the conflict and statements from the White House, means we could see average petrol prices hit 150p per litre if these elevated levels persist. While motoring organisations assert that fuel supplies are stable, they advise drivers to limit unnecessary journeys and adopt fuel-efficient driving habits.
For those who do not drive regularly, the impact of rising petrol prices can still be felt in the cost of goods and services. Increased transport costs for supermarkets, for instance, could lead to higher food prices, affecting all consumers.
Mortgage Rates on the Rise
Prior to the conflict, there was optimism regarding a decline in interest rates for fixed and variable-rate mortgages. However, that trend has reversed, with some of the UK’s major lenders raising rates in response to increased funding costs and the expectation that base borrowing rates will remain elevated.

As of Friday, the average rate for a two-year fixed mortgage has risen to 5.10%, up from 4.84% earlier this month, marking the highest rate since July. Similarly, five-year fixed mortgage rates have climbed from 4.96% to 5.19%. Economic uncertainty often leads lenders to withdraw mortgage products, and more than 500 have been taken off the market recently, although options still remain with over 7,100 deals available.
Adam French, head of consumer finance at Moneyfacts, commented on this trend, stating that withdrawing products rather than merely adjusting prices suggests that funding costs are rising too rapidly for incremental changes to keep up.
Energy Bills and Heating Oil Concerns
While households in England, Wales, and Scotland benefit from a price cap on gas and electricity bills imposed by Ofgem, this safety net is temporary and does not cover everyone. The cap is set to remain in place until July, and there are indications that prices may decrease in April. However, fluctuations in wholesale energy prices until late May will significantly affect household bills moving into the summer months. A sustained period of high costs could lead to steep increases in energy prices for many consumers.
In the past, spikes in energy prices prompted government intervention, such as the Energy Price Guarantee following the pandemic and Russia’s invasion of Ukraine. Energy Secretary Ed Miliband has indicated that the government is prepared to intervene again if necessary, although the scale of the conflict’s impact will dictate this decision.
Those relying on heating oil, particularly in rural areas and Northern Ireland, are facing even steeper price hikes—with reports suggesting costs have more than doubled since the conflict began. Campaigners are urging for support for those struggling to pay. Chancellor Rachel Reeves has announced that a package of assistance for households affected by rising heating oil costs will be unveiled soon.
The Broader Economic Picture: Inflation and Interest Rates
At the beginning of March, UK inflation was projected to hover around the Bank of England’s target of 2%. However, analysts now believe that this forecast may be overly optimistic due to the ongoing conflicts. The volatility in both the military and economic landscape complicates accurate inflation predictions, though experts do not anticipate a return to the peak inflation rate of 11.1% seen in October 2022.

Interest rates, which the Bank of England uses to control inflation, are also likely to remain higher for longer than previously expected. Following the last meeting of the rate-setting committee, Governor Andrew Bailey expressed uncertainty about future rate cuts, which analysts had initially anticipated for March. While borrowing may become more expensive, savers might find slightly better returns as economic uncertainty leads to increased savings.
Anticipating Changes in Consumer Behaviour
The implications of the Iran conflict extend beyond immediate financial concerns. Consumers could face higher costs for holidays and leisure travel as jet fuel prices have surged. While airlines may employ strategies to mitigate these costs, prolonged high prices will inevitably lead to increased ticket fares.
In summary, the unfolding situation in Iran is poised to impact various facets of personal finance, from daily expenses to long-term financial planning. As the conflict continues to evolve, consumers will need to remain vigilant and adaptable to changing economic conditions.
Why it Matters
Understanding the financial implications of the Iran conflict is crucial for consumers as it influences everything from everyday expenses to major financial decisions. With rising fuel prices, increasing mortgage rates, and the potential for high energy bills, individuals and families must prepare for a challenging economic environment. Staying informed and proactive will be key to navigating these uncertain waters and mitigating the impact on personal finances.
