As tensions escalate in the Middle East, the ongoing conflict involving Iran has begun to ripple through the UK economy, affecting everything from petrol prices to mortgage rates. While there is cautious optimism about a potential resolution, the fluctuating political landscape means that individuals must remain vigilant regarding their financial circumstances. Here’s an overview of the key areas where this conflict is influencing personal budgets.

Fuel Prices: A Volatile Landscape

Motorists have felt the pinch at the petrol pump as prices surged following the outbreak of hostilities in Iran. Although they have since receded from their peak, the volatility of crude oil prices continues to be a concern for drivers. Crude oil is a primary component of petrol and diesel, so any fluctuations in wholesale prices directly impact what consumers pay at the pump.

According to the RAC, petrol prices soared to a high of 159.53p per litre on 28 May, while diesel peaked at 191.54p on 15 April. As of now, petrol is just below 157p a litre and diesel has fallen to around 178p. However, it now costs £97.22 to fill a 55-litre family diesel car—an increase of £18.91 since the conflict began. Similarly, a full tank of petrol now costs £85.74, representing an increase of £12.68 from earlier in the year.

Price changes at the pump typically lag behind movements in wholesale markets, often taking around two weeks to reflect changes. Therefore, if the Strait of Hormuz were to reopen, it could take time for oil supplies and economic activities to stabilise. Fuel retailers have denied any claims of price gouging, and regulators have found no widespread evidence of profiteering. Nevertheless, rising transport costs may lead supermarkets to increase food prices, directly impacting household expenses.

Mortgage Rates: An Unexpected Turn

Before the outbreak of the Iran conflict, many were hopeful that interest rates on fixed and variable mortgages would decline. However, recent developments have led to increased volatility in the lending market. As lenders faced rising funding costs and revised expectations about the base rate, they quickly raised mortgage rates.

The average rate for a two-year fixed mortgage climbed from 4.83% at the beginning of March to a high of 5.90% by mid-April, before settling at around 5.61% by June. For five-year fixed deals, the average rose from 4.95% to 5.78% and has now decreased to 5.58%. This fluctuation means that many borrowers are facing higher monthly repayments than anticipated. According to the Bank of England, those transitioning to new deals can expect an average monthly payment increase of approximately £80 over the next three years. While 53% of UK mortgage holders may see their payments rise, 25% of those who secured higher fixed rates could benefit from decreased payments despite the recent uptick in rates.

Energy Bills: Navigating Uncertainty

Households in England, Wales, and Scotland currently benefit from a price cap on gas and electricity bills imposed by energy regulator Ofgem. However, this cap is temporary and does not extend to all consumers. From July, energy prices are set to increase by 13% due to higher wholesale costs. A typical dual-fuel household can expect to pay around £18 more per month, largely driven by rising gas prices.

The government previously intervened during spikes in energy costs, such as after the COVID-19 pandemic and the onset of the Ukraine conflict, with measures like the Energy Price Guarantee (EPG). The Chancellor has hinted at potential support for energy bills this winter, focusing on those most in need rather than offering universal assistance. For households using heating oil, which is especially common in rural areas and Northern Ireland, there is no price cap. In March, Prime Minister Sir Keir Starmer announced a £53 million support package for vulnerable heating oil users, with councils tasked with determining eligibility.

Inflation and the Broader Economic Picture

At the start of March, UK inflation was projected to stabilise around the Bank of England’s target rate of 2% over the next five years. However, since the conflict began, inflation rates have risen more quickly than anticipated. Analysts note that while inflation estimates have become challenging due to the unpredictable military and economic landscape, a return to the peak rate of 11.1% seen in October 2022 is not expected. The Bank of England’s adverse scenario in April suggested inflation could peak just above 6% early next year.

With the Bank of England tasked with maintaining inflation close to 2%, interest rates have become a focal point. Following meetings of the rate-setting committee, the prospect of cuts has diminished, while the potential for increases remains a concern. Should rates rise, borrowing costs may increase, but savings accounts could offer slightly better returns. In uncertain times, consumers often tighten their budgets, which can further impact economic growth across the UK.

Why it Matters

The ongoing conflict in Iran has created a complex web of economic challenges for UK households. From rising fuel and energy costs to the unpredictability of mortgage rates, the financial landscape is shifting. As consumers navigate these changes, understanding the implications on their budgets becomes crucial. The intersection of geopolitics and everyday finances underscores the importance of vigilance and adaptability in an increasingly volatile world.
