Conflict in Iran: How Rising Tensions Could Affect Your Finances

The ongoing conflict involving Iran and its implications for the US and Israel have begun to ripple through the UK economy, impacting everything from fuel prices to mortgage rates. As the situation evolves, consumers are left to navigate rising costs and uncertain financial landscapes. Understanding these changes is crucial for UK households as they adjust to the shifting economic climate.

Fuel Prices on the Rise

Motorists are already feeling the pinch at the petrol pump, with prices climbing significantly since the outbreak of hostilities. As of Friday, the average cost of petrol reached 150.11p per litre, marking a 17.3p increase since the conflict began. Diesel prices have surged even higher, now averaging 177.68p per litre—an increase of 35.3p. The RAC has pointed to these rising costs as a direct consequence of escalating crude oil prices, which have surged in response to the ongoing war.

Every $10 rise in oil prices typically translates to approximately a 7p increase at the pump, and with crude prices remaining volatile, consumers may see further fluctuations. While there is a sufficient supply of fuel, motoring organisations are urging drivers to limit non-essential travel and adopt fuel-saving driving habits to mitigate the effects of price hikes. The impact of rising fuel costs, however, extends beyond individual motorists; increased transport expenses can lead to higher prices for goods and services, particularly food.

Mortgage Rates and Borrowing Costs

Before the onset of the conflict, many anticipated a gradual decline in mortgage interest rates. However, the reality has shifted dramatically. Lenders are now rapidly increasing rates due to higher funding costs and a revised outlook on base borrowing rates. The average two-year fixed mortgage rate has jumped from 4.83% in March to 5.75%, the highest level since last year, according to financial data provider Moneyfacts. Similarly, five-year fixed rates have risen from 4.95% to 5.69%.

This tightening in the mortgage market has resulted in a significant reduction in available products, with 1,620 fewer residential mortgage options currently on offer. Adam French, head of consumer finance at Moneyfacts, noted that when lenders withdraw products rather than simply adjusting prices, it signals that funding costs have changed too rapidly for mere tweaks to suffice. This shift leaves borrowers with fewer choices at a time when they are already facing increasing costs.

Energy Bills and Heating Oil Prices

While energy bills in England, Wales, and Scotland benefit from a price cap imposed by regulator Ofgem, this protection is temporary and does not extend to all households. The cap, which sets the maximum price for energy units for those on variable deals, is set to remain in place until July. However, the future trajectory of wholesale energy prices will determine the costs faced by consumers in the summer. Cornwall Insight’s latest forecast suggests that a typical dual-fuel household could see annual energy bills rise to £1,934, up from £1,641.

For those relying on heating oil—common in rural areas and Northern Ireland—the situation is more precarious. With no price cap in place, costs can fluctuate significantly. Recently, Prime Minister Sir Keir Starmer announced £53 million in support for vulnerable heating oil users, with funds distributed via local councils. Meanwhile, the Competition and Markets Authority is investigating whether heating oil suppliers are treating customers fairly as prices rise.

Inflation and Interest Rates: A Complex Landscape

At the start of March, UK inflation was projected to hover around the Bank of England’s target of 2% over the next five years. However, the onset of conflict has altered this outlook, with analysts now predicting an uptick in inflation rates. While it is unlikely that inflation will reach the peak of 11.1% seen in October 2022, the current volatility makes forecasts challenging.

The Bank of England, tasked with maintaining inflation close to 2%, has adopted a cautious approach, holding the base interest rate at 3.75%. Analysts suggest that the next move could involve an increase rather than a decrease in rates, potentially making borrowing more expensive. However, higher interest rates could lead to improved returns for savers, albeit with diminished purchasing power due to rising living costs.

Why it Matters

The ramifications of the ongoing conflict in Iran extend far beyond geopolitical concerns; they directly affect the financial well-being of UK households. Rising fuel and energy costs, coupled with increasing mortgage rates and inflation, create an increasingly complex economic landscape. As consumers grapple with these changes, understanding their implications will be essential for making informed financial decisions in the months ahead. The interconnectedness of global events and local economies underscores the importance of vigilance and adaptability in uncertain times.
