Fuel Prices for Motorists
Drivers across the UK may have already registered a noticeable uptick in prices at the pump. By Friday, the average price for a litre of petrol had climbed to 150.11p, marking a significant 17.3p increase since the conflict’s outset. Diesel, often a bellwether for transport costs, saw an even steeper rise, surging by 35.3p to reach 177.68p per litre, according to data from the RAC motoring organisation. This direct impact on motorists stems primarily from the sharp rise in crude oil prices, which have become increasingly volatile as they react to developments in the conflict and official commentary from major global players, particularly the White House.
Analysts widely agree that every $10 surge in the price of a barrel of oil typically translates to an approximate 7p increase in pump prices. The Middle East remains a critical region for global oil supply, and any perceived threat to its stability or to key shipping routes, such as the Strait of Hormuz, can trigger speculative buying and drive up prices. While motoring organisations assert that current fuel supplies remain robust, they are actively encouraging consumers to adopt more conservative driving habits, such as reducing non-essential journeys and modifying driving styles to avoid harsh acceleration and braking, thereby conserving fuel. The impact of rising petrol and diesel prices extends far beyond individual motorists; increased transport costs for hauliers and logistics companies invariably feed into higher prices for a vast array of goods and services, including food, retail products, and even public transport fares, ultimately contributing to broader inflationary pressures across the economy.
Cost and Choice of Mortgages
In a notable shift from earlier expectations, the mortgage market is currently experiencing an upward trajectory in rates. Lenders have been quick to adjust their offerings, driven by a confluence of factors including their own rising funding costs – which are often tied to wholesale money market rates – and a recalibration of expectations regarding the Bank of England’s base borrowing rate. Previously, there was a widespread anticipation of rate cuts later in the year, but the geopolitical uncertainty has dampened this outlook, leading to fears that rates may remain higher for longer, or even see further increases if inflation becomes entrenched.
The financial information service Moneyfacts highlights this rapid escalation: the average two-year fixed-rate mortgage has jumped from 4.83% at the beginning of March to 5.75% now, reaching its highest point since March of the previous year. The most competitive deals, often the first to attract borrowers, have seen the steepest increases. Similarly, for those seeking longer-term security, the average five-year fixed rate has risen from 4.95% to 5.69% over the same period, now standing at its highest level since July 2024. This directly impacts affordability for first-time buyers and significantly increases monthly payments for homeowners looking to remortgage. For instance, a homeowner remortgaging a £200,000 loan over 25 years could see their monthly payments increase by hundreds of pounds with such a jump in rates.
Compounding the challenge, periods of economic uncertainty frequently lead lenders to withdraw mortgage products from the market, thereby reducing consumer choice. Moneyfacts reports that there are currently 1,620 fewer residential mortgage products available, though over 6,000 deals still remain. Adam French, head of consumer finance at Moneyfacts, notes, "When lenders take the step of pulling deals rather than simply tweaking pricing, it often indicates that funding costs have moved too quickly for incremental changes to keep pace." This reduced competition can mean less favourable terms and less flexibility for borrowers, adding another layer of financial strain during an already challenging period.

Energy Bills and Heating Oil Costs
For most households in England, Wales, and Scotland, gas and electricity bills benefit from a degree of protection thanks to the price cap set by the energy regulator Ofgem. This cap limits the maximum price suppliers can charge for each unit of energy for those on variable tariffs. Crucially, the current price cap, which saw prices decrease in April, is set until July. However, the wholesale energy market’s performance between now and late May will be the determining factor for household bills from the summer onwards. A sustained period of elevated wholesale costs, driven by geopolitical instability and concerns over global energy supply, could easily translate into a sharp increase in energy prices for millions of people.
Energy consultancy Cornwall Insight’s latest forecast, while speculative and subject to change, predicts that under Ofgem’s price cap for July to September, a dual-fuel household consuming a typical amount of gas and electricity could face an annual bill of £1,934, a notable rise from the current £1,641. This potential increase evokes memories of the unprecedented spike in energy prices following the Covid-19 pandemic and Russia’s invasion of Ukraine, which necessitated significant government intervention through the Energy Price Guarantee (EPG). While the Chancellor has indicated that government support could be provided if bills escalate again, it is likely to be targeted at the most vulnerable, rather than the universal approach seen with the EPG.
Those seeking to fix their energy unit prices are encountering a similar environment to mortgage seekers, with fewer attractive long-term deals available as suppliers factor in future market volatility. The most immediate and unprotected impact of rising energy prices is felt by the estimated 1.5 million households that rely on heating oil, typically stored in an outdoor tank. These properties, often located in rural areas and predominantly in Northern Ireland, have no regulatory cap limiting the cost of their fuel. Consequently, heating oil users are directly exposed to the fluctuations of the global oil market. Recognising this vulnerability, Sir Keir Starmer announced support amounting to £53m for the most vulnerable heating oil users. This funding will be distributed via devolved authorities, with local councils in England determining eligibility and methods of financial assistance. Furthermore, the Competition and Markets Authority (CMA) is actively scrutinising the market to ensure customers are treated fairly. Emma Cochrane of the CMA stressed, "Generally, we would expect that customers who have placed orders for heating oil should receive it at the agreed price. Suppliers should be clear what they are charging and terms must be fair," urging consumers to be vigilant about pricing and terms.
Higher Cost of Living but with Limits (Inflation)
At the beginning of March, the UK’s inflation rate – the key measure of the rising cost of living – was forecast by the Office for Budget Responsibility (OBR) to hover around the Bank of England’s 2% target over the next five years. The government’s official forecaster had projected the price of a typical basket of goods to increase by 2.3% this year, before settling at 2% annually from 2027. However, these calculations were made prior to the commencement of the airstrikes on Iran, fundamentally altering the economic outlook.
Now, analysts widely anticipate that the rate of inflation is unequivocally on the rise. Making precise inflation estimates has become exceedingly difficult given the highly volatile military and economic situation. The cumulative effect of increased fuel, transport, and wholesale energy costs, coupled with potential disruptions to supply chains, will inevitably feed into consumer prices across the board. Businesses facing higher operational costs will likely pass these on to consumers, leading to an upward revision of inflation forecasts. However, analysts generally do not believe inflation will return to the peak of 11.1% seen in the UK in October 2022. This distinction is crucial; the war in Ukraine, for instance, caused significant spikes in the prices of basic foodstuffs such as wheat and edible oils due to Ukraine’s critical role as a global producer of these commodities. The current conflict, while impacting energy markets profoundly, does not pose the same direct threat to global food supplies, thus mitigating one major inflationary driver seen previously. Nevertheless, persistent higher inflation would erode purchasing power and place further strain on household budgets.
Interest Rates Could Rise, Not Fall

The Bank of England’s primary mandate is to maintain inflation as close as possible to its 2% target, and its most potent tool for achieving this is the setting of interest rates. Following the rate-setting committee meeting in February, Bank Governor Andrew Bailey had indicated there was scope for further rate cuts later in the year. However, the geopolitical developments have significantly complicated this outlook. Persistent inflationary pressures stemming from elevated energy prices, transport costs, and broader supply chain disruptions could compel the Bank of England to maintain interest rates at their current high levels for longer than previously anticipated, or even consider further hikes if inflation becomes deeply entrenched.
The implications of this shift are multi-faceted. Borrowing money, whether for mortgages, personal loans, or business investments, could become more expensive than previously thought. Conversely, savings rates might become slightly more lucrative, though often still failing to keep pace with the rising cost of living. In times of heightened uncertainty, there is a historical tendency for individuals and businesses to "hoard" savings as a precautionary measure. While this might provide a buffer for some, if the overall cost of living continues to rise significantly, the real spending power of these savings will diminish. Furthermore, prolonged higher interest rates and reduced consumer spending can dampen overall economic growth in the UK, creating a challenging environment for both individuals and the wider economy.
The Price of Fun
The wider implications for our finances extend to discretionary spending and leisure activities, highly dependent on how the war and its global impact evolve. One immediate area of concern is travel. The choice of holiday destinations for the spring and summer may become more limited, and flights are likely to become more expensive. This is directly attributable to the sharp increase in the price of jet fuel, which is intrinsically linked to the cost of crude oil. Global demand for air travel, coupled with supply chain security concerns and the overall rise in oil prices, pushes up aviation fuel costs.
While airlines often employ sophisticated buying strategies, such as hedging, to mitigate some of the immediate impact of fuel price volatility, these strategies have their limits. The longer aviation fuel remains expensive, the harder it becomes for airlines to absorb these costs without passing them on to consumers through higher fares or, in some cases, reducing flight capacity and routes to manage operational expenses. This could lead to fewer available flights, less competition on certain routes, and ultimately, a more expensive and potentially less convenient travel experience for holidaymakers. Beyond travel, the broader impact of higher inflation and reduced disposable income could also affect other forms of leisure and entertainment, as consumers tighten their belts and prioritise essential spending.
In conclusion, the ongoing US-Israel war with Iran is not a distant conflict but a significant economic force with tangible repercussions for UK households. From the daily cost of commuting and heating homes to the long-term affordability of housing and the simple pleasure of a holiday, the financial landscape is undergoing a profound transformation. As global events continue to unfold, vigilance, adaptability, and careful financial planning will be paramount for individuals seeking to navigate these turbulent economic waters.
