The ongoing military confrontation in Iran has begun to reverberate through the UK economy, influencing everything from fuel prices to mortgage rates. As the conflict unfolds, its effects on the cost of living and financial markets could deepen, depending on the conflict’s duration and the resilience of global supply chains. This article examines the multifaceted economic repercussions and highlights key areas for consumers to monitor.
Rising Fuel Prices: A Burden on Motorists
Motorists across the UK are already feeling the pinch at the petrol pump, with average prices reaching an 18-month peak of 140.6p per litre as of Friday. This marks an increase of nearly 8p since hostilities in Iran escalated, while diesel prices have surged by approximately 17p, now standing at 159.2p per litre, according to figures from the RAC motoring organisation. The rising costs have sparked controversy, with retailers accusing the government of employing “inflammatory language” regarding potential profiteering from the surge in oil prices.
Analysts have noted that for every $10 increase in crude oil, pump prices tend to rise by approximately 7p per litre. Given the volatility in global oil prices, particularly in response to developments in Iran, it is plausible that average petrol prices could soar to around 150p per litre if the current trends persist. Although motoring organisations have assured consumers that fuel supplies remain adequate, they recommend reducing non-essential journeys and adopting more fuel-efficient driving styles.
It’s essential to remember that rising fuel costs inevitably cascade through the economy. Increased transport expenses for supermarkets could lead to higher food prices, affecting all consumers, not just those who drive.
Mortgage Rates on the Rise: A Shift in Borrowing Costs
In the realm of home financing, the conflict has also altered expectations regarding mortgage rates. Prior to the onset of hostilities, many anticipated a gradual decline in interest rates for new fixed-rate mortgages. However, the prevailing sentiment has shifted dramatically, with several of the UK’s largest lenders responding to increased funding costs by raising mortgage rates.

As of Friday, the average rate for a two-year fixed mortgage climbed to 5.10%, up from 4.84% just a few weeks earlier, marking the highest levels since July. Similarly, five-year fixed mortgage rates have risen from 4.96% to 5.19%. The withdrawal of over 500 residential mortgage products from the market reflects lenders’ hesitance amid rising costs, although there remain 7,147 deals available. Adam French, head of consumer finance at Moneyfacts, indicated that such withdrawals signal a rapid shift in funding costs, compelling lenders to reassess their offerings.
This tightening of the mortgage market could limit options for prospective home buyers and those looking to remortgage, particularly during a time when financial flexibility is paramount.
Energy Costs: The Impact on Household Bills
While the energy regulator Ofgem has implemented a price cap for gas and electricity bills in England, Wales, and Scotland, this measure is not permanent and does not encompass all consumers. The cap is set to remain in place until July, with prices anticipated to decrease in April. However, fluctuations in the wholesale energy market in the interim will heavily influence household bills from the summer onwards. A sustained surge in wholesale prices could prompt significant increases in energy costs for millions.
Energy Secretary Ed Miliband has communicated a willingness to intervene should it become necessary, though any such action would depend on the scale of impact stemming from the conflict. For those reliant on heating oil—especially in rural areas—price hikes have already been alarming, with costs reportedly more than doubling since the conflict’s inception. Panic buying has exacerbated this situation, leading to limited availability.
Chancellor Rachel Reeves announced plans to support households facing soaring heating oil costs, with further details expected shortly. The Competition and Markets Authority is also investigating whether customers are being treated fairly in these transactions.
Inflationary Pressures and the Future of Interest Rates
The onset of conflict has thrown previous inflation forecasts into disarray. Earlier this month, the Office for Budget Responsibility anticipated UK inflation would align with the Bank of England’s target of 2% over the next five years. However, analysts now express doubts about the accuracy of these projections, as the ongoing military situation complicates economic modelling.

While it is unlikely that inflation will reach the peak of 11.1% seen in October 2022—largely driven by the war in Ukraine affecting food prices—economic uncertainty could hinder growth and consumer spending. Furthermore, the Bank of England’s role in controlling inflation through interest rate adjustments is now fraught with complications. Previously expected cuts to borrowing costs are now off the table, as the conflict’s ramifications complicate the economic landscape.
Broader Economic Implications
As the crisis in Iran unfolds, the broader economic implications for UK households remain uncertain. The potential for increased travel costs, particularly in the aviation sector, looms large, with rising jet fuel prices likely to translate into higher ticket prices for consumers. Airlines may be forced to pass these costs on to passengers, limiting holiday options and impacting discretionary spending.
Why it Matters
The ongoing conflict in Iran is poised to reshape the financial landscape for UK households, heightening inflationary pressures and increasing costs across various sectors. As consumers grapple with rising fuel prices, heightened mortgage rates, and potential surges in energy bills, the economic ramifications could contribute to a more challenging cost-of-living crisis. Understanding these dynamics is crucial for consumers to navigate this turbulent period, make informed financial decisions, and prepare for the ongoing uncertainties ahead.
