Trumpflation and the UK Cost of Living Crisis: A Deep Dive

Britons are facing yet another surge in the cost of living, fueled by economic instability stemming from the ongoing conflict in the Middle East. Dubbed “Trumpflation,” this modern wave of economic pressure is impacting household finances across the board, from mortgage payments and energy bills to fuel and grocery costs. As the war continues, the outlook for UK consumers remains uncertain.

The Impact on Home Loans

The Iran war has had a “catastrophic” effect on the UK home loans market, with nearly 1,000 mortgage products pulled by lenders in a matter of weeks. Borrowers taking out a new two-year mortgage deal are now facing average annual costs £900 higher than before the war began, based on a £250,000 mortgage over 25 years The Guardian.

The Bank of England held rates at 3.75% on Thursday, March 20, 2026, but expectations of rate cuts have shifted towards potential rate rises in response to the escalating conflict. This shift significantly impacts both prospective homebuyers and those needing to refinance existing deals. Approximately 1.8 million fixed-rate mortgage deals are set to expire in 2026, leaving many borrowers vulnerable to higher rates The Guardian.

“The shocks caused by the unrest in the Middle East are having a catastrophic impact on the UK mortgage market,” said Rachel Springall, finance expert at data firm Moneyfacts The Guardian. The average two-year fixed mortgage rate has risen by around 0.5% to 5.35%.

Rising Energy Bills

The war has triggered an energy price shock, with experts predicting an increase of over £300 per year for a typical household energy bill. Although the price cap in England, Wales, and Scotland currently shields consumers from immediate market fluctuations, this protection is temporary. From April to June, the average annual dual-fuel bill is £1,641. However, analysis by Cornwall Insight suggests this figure could jump to £1,972 a year from July The Guardian.

The 1.5 million UK households using heating oil are particularly vulnerable, as this fuel is not protected by the price cap and has more than doubled in cost since the war began. The government has allocated £53 million to support low-income households with heating oil costs The Guardian.

Fuel Costs at the Pump

Rising energy prices are immediately reflected in fuel costs. The average price of unleaded petrol is likely to reach 150p per litre, with diesel potentially reaching 180p by Easter. Since the conflict began, petrol prices have risen by almost 12p (9%) to 144.51p per litre, and diesel by 24p (17%) to 166.24p per litre The Guardian. This adds approximately £6.40 to the cost of filling a typical family car with unleaded petrol and £13 for diesel.

The RAC suggests carpooling or working from home to mitigate fuel costs, and advises drivers to adopt fuel-efficient driving habits. Shopping around for the cheapest fuel prices using apps like PetrolPrices and myRAC is also recommended The Guardian.

The Weekly Shop: Food Price Inflation

Surging energy prices are gradually impacting the cost of groceries as higher transportation and production costs are passed down the supply chain. The prices of essential farming inputs, such as fuel and fertilizer, have already increased. Approximately one-third of the global seaborne trade in fertilizers passes through the Strait of Hormuz The Guardian.

Analysts at Jefferies predict that food price inflation will accelerate towards the end of the year. Stuart Rose, executive chair of Asda, emphasized the critical link between energy costs and the food industry, stating, “Oil and gas is to business what water is to life” The Guardian.

Travel Costs on the Rise

The travel industry warns that higher jet fuel prices will drive up airfares. Thomas Cook advises booking holidays in advance to secure the best prices, noting a 40% increase in bookings for Portugal and the Balearic Islands, and a 16% increase for the Canary Islands since the war began The Guardian.

Travel insurance costs are also increasing, particularly for travel outside of Europe. The average premium for a single trip policy to the United Arab Emirates has risen by 16%, and Turkey has seen a near 2% increase The Guardian.

UK Response and International Involvement

The United Kingdom has been actively involved in the 2026 Iran war since the joint US-Israeli airstrikes on February 28, 2026, shooting down Iranian drones and missiles over allied countries including Qatar, Iraq, and Jordan Wikipedia. Following a drone strike on a British military base in Cyprus, the UK deployed additional military assets to the island and repositioned the HMS Dragon destroyer to the Eastern Mediterranean Wikipedia. The UK is also working to evacuate its 300,000 citizens from the region Wikipedia.

Meanwhile, concerns are growing over the detention of British citizens in Iran, with families alleging they are being used as “human shields” Reuters.

As the conflict continues, the economic repercussions for the UK are expected to worsen, requiring continued vigilance and proactive measures to mitigate the impact on households and businesses.
