The ongoing conflict between the US and Israel in Iran is beginning to take a toll on the finances of households across the UK. A prominent think tank has projected that the average working-age family could see their financial situation worsen by hundreds of pounds this year due to the escalating war. With everything from fuel prices to mortgage rates affected, it’s crucial for consumers to stay informed about these economic shifts.

Fuel Price Fluctuations

Motorists have already felt the impact of the conflict, as petrol prices surged before experiencing a slight decline. Crude oil prices, which directly influence the cost at the pump, have been erratic since the start of hostilities. According to analysts, every $10 (£7.53) increase in wholesale oil prices typically translates to an approximate 7p rise per litre at fuel stations.

Since the onset of the war, disruptions to oil production and transportation in the Middle East have led to significant price volatility. For instance, the petrol price reached a staggering peak of 158.3p per litre, while diesel soared to 191.5p. As of recent data, petrol has slightly decreased to just below 157p, with diesel now at 188.5p. Despite these fluctuations, filling up a 55-litre family car has cost households an additional £14 for petrol and £27 for diesel since the conflict began.

While fuel retailers have denied any price gouging, the Competition and Markets Authority has assured consumers that it will monitor the situation closely. Motorists are encouraged to limit non-essential travel and adjust their driving habits to save fuel.

Mortgage Rate Increases

The war’s ramifications extend to the housing market as well. Pre-conflict, many hoped for a decline in mortgage interest rates. However, lenders have responded to rising funding costs by swiftly increasing rates. The average two-year fixed mortgage rate has jumped from 4.83% in early March to 5.78% today, with five-year deals rising from 4.95% to 5.68%.

The Bank of England has warned that average monthly payments for many homeowners could increase by around £80 over the next three years. Currently, about 53% of UK mortgage holders are expected to face higher payments, while roughly 25% of those who fixed their rates earlier at higher levels may see their payments decrease. This shift illustrates how geopolitical tensions can ripple through the domestic economy, affecting household budgets in unexpected ways.

Energy Bills and Heating Oil Costs

While households benefit from a price cap on gas and electricity, this protection is not universal and is set to expire in July. Recent drops in energy prices occurred as the conflict escalated, but fluctuations in the wholesale market will influence future bills. Projections suggest that by mid-summer, a dual-fuel household could see its annual energy costs rise to £1,850, up from the current £1,641.

The government’s previous intervention during the energy crisis—through the Energy Price Guarantee—may not be replicated this time, as any support would be income-based. For those relying on heating oil, often used in rural areas, the lack of a price cap means they are particularly vulnerable to rising costs. In March, Prime Minister Sir Keir Starmer announced £53 million in support for the most vulnerable heating oil users, distributed through local councils.

Inflation and Economic Outlook

Inflation, which measures the rising cost of living, was previously expected to stabilize around the Bank of England’s target of 2%. However, the conflict has complicated these predictions, with analysts now forecasting an uptick in inflation rates. While it is unlikely to reach the peak of 11.1% seen in October 2022, expectations suggest inflation could hover around 6% in the worst-case scenario.

The Resolution Foundation anticipates that the average working-age household could be £480 worse off this year due to energy price increases, although some lower-income families may find respite from above-inflation benefit increases. James Smith, the think tank’s chief economist, emphasised that while some households might receive temporary relief, the overall purchasing power is expected to decline.

Why it Matters

The conflict in Iran is more than just a distant geopolitical issue; it is a catalyst for rising costs that directly affect UK households. With petrol, mortgage rates, and energy bills all on the rise, families are facing a perfect storm of economic challenges. As inflation creeps upward and financial support remains uncertain, understanding these developments is crucial for consumers aiming to navigate a tightening budget. The impact of global events is felt at home, underscoring the interconnectedness of our economy and the importance of staying informed.
