The ongoing conflict involving Iran has begun to influence the financial landscape in the UK, with rising costs felt across various sectors. From escalating petrol prices to shifting mortgage rates, the conflict’s repercussions will depend largely on the duration of hostilities and the resilience of global supply chains. Here’s a closer look at how the situation might affect your wallet.
Rising Fuel Costs for Drivers
Motorists are already experiencing the pinch at the pump, with petrol prices rising significantly. As of Sunday, the average price of petrol surged by 4.68p to 137.51p per litre, while diesel saw a larger increase of 8.59p, reaching 150.97p per litre, according to the RAC motoring organisation. Analysts indicate that for every $10 increase in oil prices, petrol costs rise by approximately 7p per litre. Given that crude oil prices have surged by over $30 since the conflict began, it seems likely that average petrol prices will exceed 140p per litre soon, with the possibility of breaching 150p if trends continue.
While motoring groups assure that supply levels remain stable, they recommend minimising unnecessary journeys and adopting fuel-efficient driving practices. However, it’s important to note that rising fuel costs can have a broader impact, driving up the prices of goods and services as transport expenses increase. For instance, supermarkets may pass on higher transport costs, leading to more expensive groceries.
Mortgage Rates on the Rise
In the wake of the conflict, the anticipated decline in interest rates for fixed and variable mortgages has been reversed. Major UK lenders are increasing their rates, driven by rising funding costs and a bleak outlook for base borrowing rates. Homeowners looking to secure a new two or five-year mortgage deal are facing higher costs, with the average two-year fixed rate now sitting at 4.87% and the five-year rate at 4.98%, levels not seen since August of last year.

The uncertainty has led some lenders to withdraw mortgage products altogether, a move often indicative of rapidly changing funding costs. Adam French, head of consumer finance at Moneyfacts, explains that when lenders pull deals instead of merely adjusting prices, it signals that the market is responding too quickly for gradual price changes to suffice.
Energy Bills and Heating Oil Prices
Households may find some respite from escalating energy bills thanks to a price cap established by energy regulator Ofgem, applicable in England, Wales, and Scotland. However, this cap is temporary and may not cover everyone. The cap on variable energy deals is set to last until July, with a decrease in prices expected in April. Nonetheless, the wholesale energy market’s performance in the coming months will heavily influence future bills. If high wholesale prices persist, households could face significant hikes in energy costs by summer.
For those reliant on heating oil, the situation is more precarious. Campaigners report that heating oil prices have more than doubled since the onset of the conflict, driven by panic buying and limited supply. Emma Simpson, chief executive of Rural Action Derbyshire, highlights the urgency for those running low on heating oil, especially in rural areas and Northern Ireland, where support is increasingly needed.
The Broader Cost of Living Concerns
At the beginning of March, the Office for Budget Responsibility (OBR) had forecasted UK inflation to hover around the Bank of England’s target of 2% over the next five years. However, these projections were made prior to the escalation of the conflict in Iran. Analysts are now expressing scepticism about the likelihood of maintaining low inflation rates, as the current geopolitical situation adds layers of uncertainty to economic forecasts.

While inflation is unlikely to reach the peak levels of 11.1% witnessed in October 2022, the volatility stemming from ongoing conflicts complicates predictions. As the Bank of England aims to keep inflation close to its target, the possibility of interest rate cuts has diminished, making borrowing more expensive while potentially increasing the attractiveness of savings accounts.
Why it Matters
The financial ramifications of the Iran conflict extend beyond immediate costs. With rising fuel and mortgage prices combined with the potential for increased energy bills, households across the UK may soon find their budgets stretched. The interplay between geopolitical tensions and economic stability underscores the fragility of our financial systems, reminding us that global events can have a direct impact on daily life. As consumers, understanding these dynamics is vital for navigating the changing economic landscape and preparing for the financial challenges ahead.
