The ongoing conflict involving Iran and its implications for global stability are already echoing through the UK economy, affecting everything from fuel prices to mortgage rates. As the situation evolves, analysts are closely monitoring the potential long-term impacts on household budgets and broader economic conditions. The depth of this financial strain will largely depend on the duration of the conflict and the pace at which supply chains and economies can rebound.
Surge in Fuel Costs
UK motorists are acutely aware of the escalating petrol prices, which have surged since the onset of hostilities. The average cost of petrol has climbed to 152.8p per litre, marking a 20p increase since the conflict began. Diesel prices have seen an even steeper rise, now averaging 182.8p per litre—up 40p in just a few weeks. For families relying on diesel vehicles, filling a 55-litre tank now exceeds £100 for the first time since December 2022, according to data from the RAC.
This spike in prices has ignited tensions between petrol retailers and the government, with accusations of profiteering from the oil price surge. Analysts indicate that a $10 increase in oil prices typically results in a 7p rise per litre at the pump. While motoring organisations insist there are sufficient supplies available, they are advising drivers to limit unnecessary journeys and adjust driving habits to conserve fuel.
The implications of rising fuel prices extend beyond the forecourt. Increased transport costs can lead to higher prices for goods and services, particularly in the food sector, as supermarkets may pass on their elevated logistics expenses to consumers.
Mortgage Rates on the Rise
Prior to the conflict, there was cautious optimism regarding a potential decline in mortgage interest rates. However, that expectation has been upended as lenders react to rising funding costs and a shifting economic landscape. The average two-year fixed mortgage rate has surged from 4.83% at the beginning of March to 5.84%—the highest level since July 2024. Similarly, five-year fixed mortgage rates have increased from 4.95% to 5.76%, reaching their highest point since November 2023.
Economic uncertainty has prompted lenders to withdraw numerous mortgage products from the market. Data from Moneyfacts reveals that approximately 1,600 fewer residential mortgage options are currently available, although over 6,000 remain. According to Adam French, head of consumer finance at Moneyfacts, the withdrawal of mortgage products often signals that funding costs have escalated too swiftly for lenders to adjust their offerings incrementally.
Energy Bills and Heating Oil Prices
Households may find some respite from rising energy bills due to the price cap enforced by Ofgem in England, Wales, and Scotland. However, this cap is temporary and does not apply universally. The current maximum price for energy units under variable deals is set until July, with expectations of a decrease in April. Yet, fluctuations in wholesale energy prices in the coming months could significantly affect household bills starting this summer. Cornwall Insight’s projections indicate that a typical dual-fuel household could see annual energy costs rise to £1,929, up from £1,641, subject to change based on market conditions.
The volatile situation has also raised concerns for users of heating oil, particularly in rural areas and Northern Ireland, where prices are unregulated. Prime Minister Sir Keir Starmer announced a £53 million support package for vulnerable households reliant on heating oil, to be distributed through devolved authorities. The Competition and Markets Authority is also investigating fairness in pricing practices within the heating oil market.
Inflation and Interest Rate Outlook
Inflation forecasts have shifted dramatically since the onset of the conflict. The Office for Budget Responsibility (OBR) previously anticipated that UK inflation would hover around the Bank of England’s target of 2% over the next five years. However, the current geopolitical turmoil has prompted analysts to revise these projections upwards, even as they do not expect inflation to reach the peaks of 11.1% witnessed in October 2022.
As the Bank of England navigates this tumultuous economic terrain, interest rates may rise rather than fall, a departure from earlier expectations of rate cuts. This shift could make borrowing more expensive for consumers while potentially providing slightly higher returns for savers. Nonetheless, the rising cost of living could diminish the real value of savings, impacting overall economic growth.
The Broader Economic Implications
The potential ramifications of the Iran conflict on personal finances are wide-ranging. As inflationary pressures mount and borrowing costs rise, consumers may find themselves reassessing discretionary spending, including travel and leisure activities. With jet fuel prices climbing, airlines may have no choice but to pass costs onto passengers through increased fares or reduced flight availability, thereby limiting holiday options for many.
Why it Matters
The financial landscape in the UK is under significant strain as a result of the ongoing conflict in Iran. With rising fuel and mortgage costs, coupled with the uncertain trajectory of inflation and energy prices, consumers are facing a multifaceted economic challenge. Policymakers and financial institutions must remain vigilant in their responses to these developments, as the choices made today will reverberate through the economy for months, if not years, to come. The interconnectedness of global events and local financial stability underscores the importance of adaptive strategies to mitigate the impacts on everyday life.
