The recent outbreak of hostilities in Iran is already affecting the financial landscape for households across the UK. From rising fuel costs to increased mortgage rates, the repercussions of this conflict are being felt in various economic sectors. How long these impacts will persist largely hinges on the duration of the conflict and the subsequent recovery of supply chains and markets.
Rising Fuel Prices at the Pump
Motorists are beginning to notice a significant uptick in petrol prices, which reached an 18-month high of 140.6p per litre last Friday, reflecting an increase of nearly 8p since the conflict commenced. Diesel prices have surged even more dramatically, climbing around 17p to 159.2p per litre, according to the RAC. This escalation has sparked a contentious debate between fuel retailers and the government, which accused some companies of exploiting the situation for profit.
Analysts point out that a $10 increase in oil prices typically translates to an additional 7p per litre at the pump. As crude oil prices remain volatile, influenced by the conflict and political commentary from the US, future petrol prices could exceed 150p per litre if conditions do not stabilise soon. While motoring organisations assure drivers that fuel supplies remain adequate, they urge a reduction in non-essential travel and recommend more economical driving practices to conserve fuel.
However, the impact of rising fuel prices extends beyond individual motorists. Increased transport costs for goods could lead to higher prices in supermarkets and other retail sectors, thereby affecting everyone, regardless of whether they own a car.
Mortgage Rates on the Rise
The onset of the conflict has complicated the mortgage landscape, which had previously shown signs of stabilisation. Lenders have begun raising rates in response to increased funding costs and the fading expectation of base rate cuts. The average rate for a two-year fixed mortgage has surged to 5.10%, a notable jump from 4.84% just weeks prior. Meanwhile, five-year fixed mortgage rates have also increased, reaching their highest level since April at 5.19%.

In times of economic uncertainty, lenders often withdraw mortgage products from the market, reducing options for prospective buyers. Reports indicate that over 500 mortgage deals have been pulled, although more than 7,100 options remain available. Adam French, head of consumer finance at Moneyfacts, noted that such drastic measures signal rapid changes in funding costs that require more than just minor adjustments in pricing.
Energy Bills and Heating Oil Costs
Households may find some relief from rising energy bills due to the price cap implemented by Ofgem, which governs gas and electricity costs in England, Wales, and Scotland. However, the cap is temporary and does not encompass all households. The maximum price per unit is set until July, and while prices are expected to decrease in April, the fluctuations in the wholesale energy market in the coming months will largely dictate future household energy expenses.
If wholesale prices remain elevated, millions could face increased energy bills in the summer. Energy Secretary Ed Miliband has stated that the government is prepared to intervene if necessary, depending on the scale of the financial impact from the conflict. Meanwhile, those reliant on heating oil—particularly in rural areas—are experiencing steep price hikes, with costs reportedly more than doubling since the conflict began. Chancellor Rachel Reeves has promised support for households struggling with these soaring heating oil costs, with details to be unveiled shortly.
The Broader Economic Implications
The economic ramifications of the Iran conflict resonate beyond immediate price increases. Just last month, the Office for Budget Responsibility had forecasted UK inflation stabilising close to the Bank of England’s target of 2%. However, the outbreak of hostilities has complicated these predictions. While analysts do not anticipate a return to the peak inflation rate of 11.1% seen in October 2022, the uncertainty surrounding the conflict makes accurate forecasting increasingly difficult.

With the Bank of England tasked with keeping inflation in check, expectations for interest rate cuts have shifted dramatically. Analysts, who once anticipated reductions in March, are now more cautious. While borrowing costs may rise, the potential for higher returns on savings could entice consumers to save more, although this could dampen overall economic growth as spending power diminishes.
Why it Matters
The ongoing conflict in Iran poses a significant threat to the financial stability of individuals and households in the UK. Rising costs across various sectors—from fuel and mortgages to energy bills—are likely to strain family budgets and alter spending habits. As the situation develops, the long-term economic implications could reshape the financial landscape, influencing everything from inflation rates to consumer confidence. Understanding these dynamics is crucial for individuals seeking to navigate this turbulent period effectively.
