The ongoing war in Iran has begun to ripple through the UK economy, affecting everything from fuel prices to mortgage rates. As geopolitical tensions persist, understanding how these developments will influence personal finances is crucial for consumers. With some signs of potential resolution appearing, the situation remains precarious, and its implications for individual budgets could change rapidly.

Fuel Prices: A Volatile Landscape

Motorists have felt the pinch at the petrol pump, with prices surging since the onset of hostilities. However, after peaking, they have shown signs of levelling off. Crude oil, a primary component of petrol and diesel, has seen its wholesale price fluctuate dramatically due to disruptions in energy production and transportation within the Middle East.

The RAC reported that petrol prices reached a high of 159.53p per litre on 28 May, while diesel peaked at 191.54p on 15 April. Currently, petrol sits just below 157p per litre, and diesel hovers around 178p. Filling a 55-litre family car with diesel now costs £97.22, an increase of £18.91 since February, while petrol costs £85.74 to fill, up £12.68 from the conflict’s onset.

The process of transporting oil means that any shifts in wholesale prices typically take around two weeks to reflect at the pump. Consequently, even if the Strait of Hormuz were to reopen, it would take time for economic activity and oil supply to stabilise. Fuel retailers have refuted claims of price gouging, and the regulator has found no widespread evidence of unethical pricing practices. However, rising fuel costs can have a knock-on effect, potentially increasing prices for goods and services, particularly food.

Mortgage Rates: A Shifting Terrain

Prior to the conflict, there were expectations of a gradual decline in mortgage interest rates. Yet, the current climate has proven to be anything but predictable. Lenders have reacted swiftly to rising funding costs, leading to an uptick in both fixed and variable mortgage rates.

The average rate for a two-year fixed mortgage surged from 4.83% in early March to a peak of 5.90% by 12 April, before settling at around 5.61% by mid-June. Similarly, five-year fixed rates rose from 4.95% to 5.78% and now rest at 5.58%. Consequently, many homeowners are facing higher repayments than initially planned. The Bank of England projects that average monthly payments for those renewing their mortgages could rise by around £80 over the next three years, affecting approximately 53% of UK mortgage holders. Interestingly, about a quarter of those who had fixed rates previously may see their payments decrease, despite the recent uptick in overall rates.

Energy Bills: A Double-Edged Sword

Households are currently shielded from some energy price hikes due to the price cap set by Ofgem in England, Wales, and Scotland. However, this cap has limits and is set to rise by 13% in July, adding approximately £18 to monthly energy bills for a typical dual-fuel household. This increase is primarily driven by escalating wholesale gas prices.

The Chancellor has hinted at potential government support for households struggling with their energy bills as winter approaches, although this assistance will likely be means-tested, targeting those most in need rather than being universal. The situation remains fluid, with uncertainties surrounding prices beyond October.

Moreover, those relying on heating oil, especially in rural areas, are feeling the most immediate impact since there is no price cap on this fuel. Prime Minister Sir Keir Starmer recently announced £53 million in support for vulnerable heating oil users, with funds distributed through local councils. Competition authorities are also investigating whether these customers are being treated fairly.

Inflation: A Complicated Picture

Earlier this year, UK inflation was projected to align closely with the Bank of England’s target of 2% over the next five years. The Office for Budget Responsibility (OBR) anticipated a modest 2.3% increase in the cost of a typical basket of goods this year. However, these forecasts were made before the escalation of conflict in Iran.

Currently, inflation is rising at a faster rate than expected, but analysts do not foresee a return to the peak of 11.1% recorded in October 2022, largely due to the different factors influencing prices compared to the Ukraine conflict. In April, the Bank of England predicted inflation would exceed 6% early next year in its most adverse scenario.

Interest Rates: The Future Is Uncertain

The Bank of England’s primary responsibility is to control inflation, predominantly through manipulating interest rates. Earlier this year, there was optimism regarding potential rate cuts. However, the recent geopolitical instability has shifted this outlook.

The Bank has maintained the base rate at 3.75% in recent meetings and is prepared to act if inflation pressures escalate due to the Iran war. The prospect of imminent rate cuts has diminished, and while the possibility of an increase remains, it would make borrowing more costly. Conversely, higher rates could benefit savers, although the purchasing power of those savings may decline in an inflationary environment.

Why it Matters

As the situation in Iran continues to evolve, its repercussions are being felt across the UK economy, affecting the cost of living, housing affordability, and energy expenses. For consumers, staying informed about these developments is crucial. The interplay of geopolitical events and everyday financial realities underscores the importance of understanding how external factors directly impact personal budgets. As households brace for potential further increases in essential costs, the need for effective financial planning and support is more pressing than ever.
