The ongoing conflict involving Iran and its implications for the US-Israel relations are already reverberating through the UK economy, impacting everything from fuel prices to mortgage rates. As the situation develops, understanding the economic ramifications becomes critical for consumers and businesses alike. The depth and duration of these financial effects hinge on the ongoing conflict’s trajectory and its influence on global supply chains.
Fuel Prices Surge
UK motorists are feeling the financial strain as petrol prices have surged dramatically, reaching an average of 152 pence per litre—an increase of 17.3 pence since the onset of hostilities. Diesel prices have also escalated, now standing at 181.2 pence per litre, the highest level observed since December 2022. This price spike has ignited controversy between petrol retailers and the government, with retailers accusing officials of employing “inflammatory language” regarding potential profiteering amid the crisis.
Analysts warn that for every $10 increase in crude oil prices, petrol costs typically rise by approximately 7 pence per litre. The volatility of crude oil prices is closely tied to developments in the conflict and statements from political leaders, particularly in the US. While motoring organisations assert that supply levels remain adequate, they are advocating for reduced non-essential travel and encouraging drivers to adopt more fuel-efficient driving habits.
The ramifications extend beyond individual drivers; increased transportation costs can lead to higher prices for goods and services. For instance, if supermarkets experience a hike in transport expenses, consumers may see this reflected in food prices.
Mortgage Rates on the Rise
Prior to the outbreak of conflict, there was cautious optimism regarding a gradual decline in interest rates for fixed-rate mortgages. However, the current landscape tells a different story. Lenders are reacting to rising funding costs and a revised outlook on base borrowing rates, resulting in a swift increase in mortgage rates.
According to Moneyfacts, the average two-year fixed mortgage rate has soared from 4.83% in early March to 5.84%—the highest level since July 2024. For those considering five-year fixed mortgages, rates have similarly climbed from 4.95% to 5.76%, marking a peak not seen since November 2023. In times of economic uncertainty, lenders often withdraw mortgage products from the market, which now has about 1,600 fewer options available, although more than 6,000 deals remain.
Adam French, head of consumer finance at Moneyfacts, notes that lenders’ decisions to withdraw products signal a significant shift in funding costs that may not align with incremental pricing adjustments.
Energy Bills and Heating Oil Costs
The impact on household energy bills presents a mixed picture. While the energy price cap, enforced by Ofgem, provides some relief for gas and electricity customers in England, Wales, and Scotland, this protection is limited and does not extend universally. The cap, which is set to remain until July, offers temporary respite, particularly as prices are expected to decline in April. However, fluctuations in wholesale energy prices in the coming months could lead to substantial increases for many households if elevated costs persist.
Current forecasts from energy consultancy Cornwall Insight suggest that a typical dual-fuel household might see annual bills rise to £1,929 in the latter half of the year, up from £1,641. This projection, however, is susceptible to change based on market conditions. The government has indicated potential support measures for those most affected by rising energy costs, although this assistance would be more targeted than the previous Energy Price Guarantee (EPG).
For those reliant on heating oil—particularly in rural areas—there is no cap on prices, which presents an immediate financial burden. Recognising this challenge, Prime Minister Sir Keir Starmer has announced a £53 million support package aimed at vulnerable users of heating oil, to be administered by local authorities.
Inflationary Pressures and Interest Rate Outlook
As of early March, UK inflation was anticipated to align closely with the Bank of England’s target of 2% over the next five years. However, the recent outbreak of conflict has upended these projections, with analysts now forecasting an increase in inflation rates. While it is unlikely that inflation will return to the record 11.1% seen in October 2022, due to differing factors from previous crises, the current volatility complicates economic forecasting.
The Bank of England’s primary tool for controlling inflation is interest rates. Following a meeting in February, Governor Andrew Bailey indicated a potential for rate cuts, but the subsequent decision to maintain the Bank rate at 3.75% suggests a shift in strategy. Many analysts now predict that the next movement in interest rates will be upwards, not downwards, making borrowing more expensive.
Conversely, this environment of economic uncertainty may lead individuals to save more, which could have a dampening effect on overall economic growth as consumer spending declines.
The Broader Economic Implications
The financial consequences stemming from the Iran conflict extend beyond immediate price increases, influencing consumer choices and broader economic stability. As flight costs rise due to escalating jet fuel prices, holiday options may become increasingly limited for UK travellers. Airlines, while employing strategies to mitigate the impact of rising fuel costs, may still have to pass these expenses onto consumers through higher fares or reduced flight availability.
Why it Matters
The unfolding situation in Iran is more than just a geopolitical concern; it has tangible implications for the UK economy and its consumers. The ripple effects of rising fuel and energy prices, coupled with increasing mortgage rates, threaten to strain household budgets and dampen economic growth. As individuals grapple with these financial pressures, the need for targeted government support becomes imperative to safeguard the most vulnerable segments of society. Understanding these dynamics is essential for navigating the turbulent economic landscape ahead.
