Global Conflict Raises Costs: How the Iran War is Affecting Your Finances

The ongoing conflict between the US and Iran is beginning to cast a shadow over the financial landscape in the UK, with rising prices impacting everything from fuel to mortgages. As the situation evolves, experts warn that the repercussions could deepen, affecting household budgets and overall economic stability.

Fuel Prices on the Rise

Motorists across the UK are already feeling the pinch at the petrol pump. By Sunday, average petrol prices had jumped by 4.68 pence to 137.51 pence per litre, while diesel surged by 8.59 pence to 150.97 pence, according to the RAC. Analysts suggest that for every $10 increase in crude oil prices, petrol costs can rise by approximately 7 pence per litre. With crude oil prices soaring over $30 since the onset of the conflict, it’s likely that average petrol prices will exceed 140 pence per litre soon, with 150 pence per litre looming on the horizon if oil prices do not decline.

While motoring organisations assert that fuel supplies remain adequate, they are urging drivers to consider reducing unnecessary travel. Additionally, adjusting driving habits—such as avoiding rapid acceleration and hard braking—can help conserve fuel and mitigate rising costs. However, the ripple effect of increased fuel prices extends beyond individual drivers; higher transportation costs for supermarkets could soon translate into elevated food prices, impacting everyone.

Mortgage Rates Under Pressure

The housing market is also feeling the strain as mortgage rates begin to climb. Before the conflict erupted, there had been optimism surrounding the potential for declining interest rates on new fixed-rate mortgages. Sadly, that outlook has shifted. Leading lenders have increased rates due to rising funding costs and a revised expectation that the base borrowing rate won’t decrease as anticipated.

Currently, the average rate for a two-year fixed mortgage has risen to 4.87%, while the five-year fixed rate has reached 4.98%—the first time both have surpassed 5% since August of last year. This shift poses a significant challenge for homeowners seeking new deals or looking to renew existing agreements. Additionally, some lenders have begun withdrawing mortgage products altogether, signalling a tightening of market options. Adam French, head of consumer finance at Moneyfacts, noted that such withdrawals often indicate that funding costs have surged too rapidly for incremental adjustments to suffice.

Rising Energy Bills and Heating Oil Costs

Household energy bills are another area of concern, despite existing protections due to the price cap implemented by Ofgem in England, Wales, and Scotland. This cap, which is set to remain in place until July, does not extend to all households, and while some prices are projected to decrease in April, the volatile wholesale energy market could lead to future increases.

The last significant energy price surge, prompted by the COVID-19 pandemic and geopolitical tensions, forced government intervention through the Energy Price Guarantee. Currently, those seeking fixed energy tariffs are facing a similar predicament as mortgage seekers, with some energy providers withdrawing deals or raising prices. The immediate impact is felt most acutely by those reliant on heating oil, which has seen prices more than double since the conflict began. Emma Simpson, chief executive of Rural Action Derbyshire, commented on the urgent need for support for those struggling to afford heating oil, especially in rural areas and Northern Ireland.

Implications for Inflation and Interest Rates

Inflation forecasts in the UK had originally indicated a return to target levels of around 2% over the next five years. However, these projections were made prior to the escalation of conflict in Iran. Analysts now anticipate that the volatile situation will complicate inflation estimates significantly. Although a return to the peak inflation rate of 11.1% experienced in October 2022 appears unlikely, the instability in the global market poses new challenges.

With the Bank of England’s mandate focused on keeping inflation close to its target, the recent turmoil has cast doubt on potential interest rate cuts previously anticipated for March. While borrowing costs may rise, there is a possibility that savings accounts could offer better returns as consumers respond to economic uncertainty by saving more. Nevertheless, the broader economic impact could hinder growth, as rising living costs erode purchasing power.

The Cost of Leisure and Travel

The wider financial implications of the conflict extend to leisure and travel, with potential consequences for holiday plans this spring and summer. As airlines grapple with soaring jet fuel prices, the likelihood of increased flight costs looms large. Though airlines often employ purchasing strategies to buffer against immediate price spikes, sustained high fuel costs may compel them to pass those expenses onto consumers in the form of higher fares.

Why it Matters

As the conflict between Iran and the US continues, its effects are reverberating through various sectors of the UK economy, significantly impacting household finances. With rising fuel and mortgage costs, alongside the potential for increased energy bills, families may need to adjust their budgets and spending habits. This turbulent period serves as a reminder of how interconnected global events can shape local economies and everyday lives, making it crucial for individuals to stay informed and prepared for potential financial shifts ahead.
