The escalating conflict between the US and Iran is already reverberating through the UK economy, affecting everything from fuel prices to mortgage rates. As tensions rise, consumers are beginning to feel the financial strain, with immediate implications for household budgets and future economic stability. The duration of the conflict and its wider geopolitical ramifications will significantly influence the long-term effects on prices and economic growth.

Rising Fuel Prices Impacting Motorists

UK motorists are witnessing a notable surge in fuel costs, with average petrol prices reaching £1.5011 per litre as of last Friday, reflecting an increase of 17.3 pence since the onset of the conflict. Diesel prices have surged even more dramatically, up 35.3 pence to £1.7768 per litre, according to the RAC motoring organisation. This inflation in fuel costs has ignited a dispute between petrol retailers and government officials, with claims of price gouging emerging amidst widespread accusations of “inflammatory language” from the government.

Analysts estimate that a $10 rise in oil prices typically translates to an approximate 7 pence increase at the pump. As crude oil prices continue to fluctuate in response to the conflict and statements from the White House, motoring organisations are urging drivers to limit unnecessary journeys and consider fuel-efficient driving habits. However, the implications extend beyond individual motorists; higher transportation costs are likely to ripple through to the prices of goods and services, particularly food, as supermarkets grapple with increased logistics expenses.

Mortgage Rates and Housing Market Uncertainty

Before the outbreak of hostilities, there was cautious optimism regarding a decline in interest rates for fixed and variable mortgage products. However, the recent turmoil has reversed these expectations, prompting lenders to swiftly raise their rates in response to escalating funding costs. The average two-year fixed mortgage rate has surged from 4.83% in early March to 5.75%, marking its highest level since last year. Similarly, five-year fixed rates have climbed from 4.95% to 5.69% during the same period.

The turmoil in the mortgage market has also led to a contraction in available products, with over 1,620 fewer options currently on offer. Adam French, head of consumer finance at Moneyfacts, noted, “When lenders take the step of pulling deals rather than simply tweaking pricing, it often indicates that funding costs have moved too quickly for incremental changes to keep pace.” As uncertainty looms, prospective homeowners may find their choices limited, heightening the pressure on those seeking to enter the housing market.

Energy Bills and the Heating Oil Crisis

Despite some protections for gas and electricity bills from the energy price cap implemented by Ofgem, the long-term outlook for household energy expenses remains precarious. This cap, which governs variable energy rates, is set to expire in July, and a sustained period of elevated wholesale energy prices could lead to significant increases for consumers. Cornwall Insight’s latest projections indicate that a typical dual-fuel household could see annual bills rise to £1,934 from the current £1,641, although these estimates are subject to significant variability.

While the government has signalled potential targeted support for vulnerable households, the absence of a universal cap on heating oil prices leaves many rural consumers particularly exposed. Prime Minister Sir Keir Starmer has pledged £53 million in support for those reliant on heating oil, with distribution managed by devolved administrations. The Competition and Markets Authority is also monitoring the situation to ensure fair treatment of customers in this volatile market.

Inflation and Interest Rate Projections

As of early March, inflation in the UK was forecast to hover around the Bank of England’s target of 2%. However, with the escalation of hostilities in Iran, analysts now predict an upward trajectory in inflation rates. The Office for Budget Responsibility previously estimated a 2.3% increase in the cost of a typical basket of goods for the year, but this calculation predates the conflict.

While experts believe that inflation is unlikely to reach the peak of 11.1% witnessed in October 2022, the current geopolitical climate complicates predictions. The Bank of England, tasked with maintaining inflation at 2%, is now faced with the prospect of raising interest rates rather than lowering them, a shift that could make borrowing more expensive while potentially offering slightly better returns for savers.

The Broader Economic Implications

The unfolding situation in Iran has far-reaching consequences for the UK’s economic landscape. As consumers brace for higher prices and tightening budgets, discretionary spending may decline, impacting sectors such as travel and hospitality. The cost of flights is expected to rise sharply due to increased jet fuel prices, which airlines may pass on to consumers through elevated fares or reduced flight availability.

With the conflict’s trajectory uncertain, UK consumers must remain vigilant about the potential for ongoing financial strain. The interplay between geopolitical events and domestic economic conditions will be crucial in determining the scale and duration of these impacts.

Why it Matters

The current conflict in Iran serves as a stark reminder of how geopolitical instability can have immediate and profound effects on everyday financial realities for consumers. As fuel, mortgage, and energy costs continue to escalate, the challenge for households will be to navigate these pressures while seeking stability in an increasingly uncertain economic environment. The long-term repercussions of this conflict could reshape consumer behaviour, inflation expectations, and ultimately, the trajectory of the UK economy.
