The ongoing conflict in Iran is generating significant economic turbulence, with repercussions poised to affect the financial landscape of households across the United Kingdom. As petrol prices surge and mortgage rates climb, the long-term effects on consumer spending and living costs remain uncertain. The duration of the conflict will play a crucial role in shaping the trajectory of these economic indicators.

Fuel Prices: A Rising Burden for Motorists

UK motorists have already felt the sting of escalating fuel prices, with the average cost of petrol reaching 150.11p per litre, marking a 17.3p rise since hostilities began. Diesel prices have surged even more dramatically, increasing by 35.3p to 177.68p per litre, according to the RAC. This spike has ignited a debate between petrol retailers and the government, with retailers accusing officials of using “inflammatory language” when suggesting that companies might be profiteering from the oil price hike.

Analysts indicate that for every $10 increase in crude oil prices, petrol costs at the pump typically rise by approximately 7p per litre. As crude prices fluctuate due to the evolving situation in Iran, motorists are being advised to reduce non-essential journeys and adjust their driving habits to conserve fuel. Although supply levels remain stable, the broader implications of rising fuel costs could ripple through the economy, potentially inflating the prices of goods and services linked to transport.

Mortgage Rates: A Shift in Financial Landscape

Prior to the onset of conflict, there was optimism regarding a continued decline in interest rates for both fixed and variable mortgage products. However, lenders have reacted to the instability by rapidly increasing rates. The average two-year fixed mortgage rate has escalated from 4.83% in early March to 5.75%, the highest level observed since the previous March. Similarly, five-year fixed mortgage rates have surged from 4.95% to 5.69% during the same period.

The tightening of mortgage options is evident, with a reduction of 1,620 residential mortgage products available in the market, although over 6,000 options still exist. Adam French, head of consumer finance at Moneyfacts, noted that lenders pulling products off the market often signifies a rapid shift in funding costs that outpaces simple price adjustments. This contraction in choice could lead to increased financial pressure for potential homeowners as market conditions become more unfavourable.

Energy Costs: A Looming Concern for Households

The UK’s energy sector is experiencing its own set of challenges amid the ongoing conflict. Although the energy regulator Ofgem has implemented a price cap to protect consumers in England, Wales, and Scotland, this measure is temporary and does not encompass all households. The cap, set to expire in July, currently limits the maximum price for variable energy deals, but any sustained elevation in wholesale energy costs could lead to significant increases in household bills come summer.

Cornwall Insight’s latest projections suggest that a dual-fuel household’s annual energy expenditure could rise from £1,641 to £1,934 as of July, a forecast that remains contingent on the volatility of the wholesale market. The government has hinted at potential support measures for vulnerable households, although any assistance would be more targeted than previous initiatives like the Energy Price Guarantee (EPG). Additionally, rural consumers reliant on heating oil—often stored in tanks—face unregulated prices, which can fluctuate dramatically. Prime Minister Sir Keir Starmer has announced £53 million in support for these users, to be allocated through devolved authorities.

The Broader Economic Picture: Inflation and Consumer Confidence

As the conflict unfolds, inflationary pressures are poised to rise, challenging the Bank of England’s previous forecasts. At the start of March, inflation was projected to hover around the Bank’s target of 2%, but analysts now anticipate a deviation from this expectation. The Office for Budget Responsibility had predicted a moderate 2.3% rise in the cost of a typical basket of goods for this year, but the onset of conflict complicates these estimates.

While the Bank of England’s primary strategy to combat inflation involves adjusting interest rates, the current climate suggests a potential increase rather than a decrease. This shift could make borrowing more expensive, while simultaneously offering slightly better returns on savings. However, consumer behaviour may shift towards saving rather than spending, which could hinder overall economic growth.

Why it Matters

The economic implications of the Iran conflict extend far beyond immediate price increases. As households grapple with rising costs across fuel, housing, and energy, the potential for decreased consumer spending looms large. This situation poses a risk to the broader UK economy, as consumer confidence wanes and economic growth slows. The interconnectedness of global markets means that the fallout from this conflict could reverberate for months, making it imperative for policymakers to respond effectively to protect vulnerable households while navigating the complexities of an unpredictable geopolitical landscape.
