The ongoing conflict involving Iran has begun to reverberate through the UK economy, significantly impacting consumer prices across various sectors. From surging petrol costs to escalating mortgage rates, the financial ramifications are becoming increasingly evident. The duration of the conflict and its subsequent effects on supply chains will ultimately dictate the depth of this economic strain.
Fuel Prices Surge Amidst Geopolitical Tensions
Motorists in the UK have felt the immediate effects of rising fuel prices since the onset of the conflict. The average cost of petrol has reached £1.528 per litre, marking a £0.20 increase since the hostilities began. Diesel has seen an even steeper rise, currently averaging £1.828 per litre—up £0.40 since early March. The cost to fill a typical family car with diesel has now surpassed £100 for the first time since December 2022, hitting £100.52.
This escalating trend has ignited a heated debate between petrol retailers and the government, with accusations of profiteering amid rising oil prices. Analysts estimate that every $10 increase in crude oil prices translates to an approximate £0.07 hike at the pump. While motoring organisations assert that fuel supplies remain stable, they advise drivers to limit unnecessary travel and adjust their driving habits to conserve fuel.
Beyond the immediate impacts on motorists, rising petrol prices often lead to increased costs for goods and services. The transport expenses for supermarkets, for instance, could translate into higher food prices, further squeezing household budgets.
Mortgage Rates on the Rise
Before the commencement of hostilities, there was optimism surrounding a potential decline in interest rates for fixed-rate mortgages. However, the landscape has shifted dramatically. Lenders have reacted swiftly to rising funding costs and the anticipated stability of the Bank of England’s base rate, leading to an increase in mortgage rates.
According to financial data provider Moneyfacts, the average two-year fixed mortgage rate has surged from 4.83% in early March to 5.84%—the highest figure recorded since July 2024. For five-year fixed deals, the average rate has escalated from 4.95% to 5.76%. In an environment of economic uncertainty, lenders are not only raising rates but also withdrawing mortgage products from the market. Currently, there are approximately 1,600 fewer residential mortgage options available compared to earlier this year, although over 6,000 deals remain.
Adam French, head of consumer finance at Moneyfacts, notes that the withdrawal of products often signifies a rapid shift in funding costs, indicating a precarious financial climate.
Energy Bills and Heating Oil Prices Under Scrutiny
Households in England, Wales, and Scotland enjoy some protection from rising gas and electricity costs due to the energy price cap set by Ofgem, although this cap is temporary and excludes certain consumers. Current forecasts suggest that while energy prices may decline in April, the summer months could bring renewed volatility. Should wholesale energy prices remain elevated, millions of households could see significant increases in their bills.
Cornwall Insight predicts an average dual-fuel household will pay £1,929 annually under the price cap for the July to September period—up from £1,641. The government has hinted at potential targeted support for vulnerable households, although this assistance is unlikely to be as comprehensive as previous measures like the Energy Price Guarantee.
The effects of rising energy costs are particularly acute for those reliant on heating oil, commonly used in rural areas. With no price cap in place, constituents in these regions are facing financial strain. Prime Minister Sir Keir Starmer has announced a £53 million support fund for those most affected, to be distributed through local authorities.
The Broader Economic Implications
As inflationary pressures resurface, the Bank of England faces an uphill battle in maintaining its target rate of 2%. The Office for Budget Responsibility had predicted inflation levels would hover around this target; however, the escalating conflict has muddied those forecasts. Analysts now anticipate a rise in inflation rates, although they remain hopeful that peaks akin to the 11.1% recorded in October 2022 will not be replicated, given the absence of significant supply disruptions like those seen during the Ukraine conflict.
In this precarious climate, interest rates are expected to rise rather than fall, leading to increased borrowing costs. While consumers may face tighter budgets, savers could benefit from slightly higher returns on savings accounts. However, the broader economic landscape could suffer as higher costs erode disposable income, potentially stunting overall growth.
Why it Matters
The unfolding situation in Iran has far-reaching implications for UK households, affecting everything from daily commuting expenses to long-term financial commitments like mortgages. As consumers grapple with rising costs, the potential for decreased spending power looms large, threatening to stifle economic growth. The interplay between geopolitical events and local economies underscores the interconnectedness of modern financial systems, making it essential for both policymakers and consumers to remain vigilant and adaptable in these uncertain times.
