Middle East War Triggers Fresh UK Financial Turmoil
The escalating conflict in the Middle East, though geographically distant, is sending shockwaves through the UK economy, threatening to ignite a new cost of living crisis. Surging energy prices and volatile financial markets could reverse recent gains in living standards, putting household finances under severe strain.
Mortgage Rates Set to Climb Amid Interest Rate Uncertainty
Britons had welcomed a period of cheaper home loans after the Bank of England reduced interest rates four times in 2025, bringing the base rate down to 3.75%. However, this relief may be short-lived. Prior to Friday, the probability of another rate cut this month stood at 80%, but it has now plummeted to less than 30%. Traders now anticipate only one cut by year-end, down from two expected last week.
According to the National Institute of Economic and Social Research, if the current spike in energy costs persists for a year, interest rates could soar to 4.5%. The thinktank modelled scenarios where oil and gas prices increase by 30% and 50% respectively over one year, which would stoke inflation into 2026 and 2027, driving the base rate upward. This projection assumes rates remain at 3.75% rather than falling as previously forecast.
Fixed-rate mortgage deals are heavily influenced by money market swap rates, which have hit 30-day highs in response to the conflict. Two-year swaps rose 26 basis points from 3.33% on Friday to 3.59% by Wednesday morning, while five-year swaps increased 21 basis points to 3.71%, according to data from Moneyfacts.
Adam French, head of consumer finance at Moneyfacts, noted that the financial turmoil has led to a rapid shift in interest rate expectations, with an "almost instantaneous" impact on the mortgage market. He added, "Some lenders have already paused or reconsidered planned rate reductions."
Energy Bills Face Potential Surge Despite Recent Cap Drop
Just last week, there was optimism as Ofgem announced a 7% reduction in the energy price cap from April, setting it at £1,641 for a typical annual dual-fuel household. Analysts had predicted stable energy costs for the remainder of the year, but these forecasts are now in jeopardy.
Following sharp increases in wholesale gas prices on Wednesday, analysts at Cornwall Insight revised their forecast for the July to September price cap upward to £1,801. This represents a £160 or 10% rise from the April cap, which currently stands at £1,758.
Craig Lowrey, principal consultant at Cornwall Insight, cautioned, "While the rise is eye‑catching, any immediate concern should be tempered. We are still early in the assessment period for the July cap, and what happens in the energy markets over the next three months will be the key factor."
The Resolution Foundation, in its analysis of new economic forecasts presented by the chancellor, warned that an energy price shock could cause living costs to accelerate again. If sustained, these rises could add over £500 to typical household energy bills in the summer and roughly one percentage point to inflation, delivering another unwelcome cost of living shock to families.
Although the surge in gas prices has been significant, analysts emphasise that the market impact so far remains far smaller than the shock triggered by Russia's 2022 invasion of Ukraine.
Stock Market Investments: Stay Calm and Diversify
For those with stock market investments, the advice is clear: do not panic. The UK's FTSE 100 share index has lost about 3% of its value this week, declining sharply on Monday and Tuesday before a partial recovery on Wednesday. However, losses are only realised if shares are sold; holding investments until prices recover is often the best strategy.
Jemma Slingo at Fidelity International recommends staying invested during volatile periods. "When markets hit rocky waters, jumping in and out should be avoided, otherwise you run the risk of missing out on unexpected opportunities that might arise from market corrections," she said. This is an opportune time to ensure a broad range of investments.
Susannah Streeter at Wealth Club noted that investors have been bracing for geopolitical tensions and must now prepare for another rollercoaster ride. For long-term investors, "big bumps in the road are part of the journey." She added that assets such as gold and defensive stocks—including utilities, healthcare firms, and consumer staples—tend to be more resilient during unpredictable times.
Even individuals without direct shareholdings may be affected, as workplace and personal pension schemes invest in stock markets alongside other assets like property and bonds. In defined contribution schemes, pension values depend on investment performance. Younger savers often have riskier investments due to longer time horizons, while those nearing retirement typically shift to less-risky assets such as cash and bonds.
For retirees using pension drawdown, selling investments for income may not be advisable during current market conditions.
Household Finances: Gains at Risk of Being Wiped Out
The overall financial outlook for UK households remains uncertain. Chancellor Rachel Reeves recently stated that Britons would be "over £1,000 a year better off by the next election" compared to the final year of Tory rule, based on average disposable income. However, this benchmark is low given the decline in living standards under the previous government.
Much of the projected improvement could be erased if the war persists. Higher energy prices immediately impact consumers through petrol pump prices; each $10 per barrel rise in oil typically adds about 0.1 percentage points to inflation within months, with further increases as costs trickle down supply chains.
Simon Williams of the RAC reported that the average petrol price has increased by nearly 2.5p per litre since Saturday, with diesel up more than 3p, following oil surging above $81 a barrel. If oil reaches $90, petrol could exceed 140p per litre, and $100 could push it toward 150p. He added, "Providing oil stays around this level the average price of petrol shouldn’t really rise to more than 136p. Diesel, however, is increasing at a faster rate."
Other pressures are also mounting. While there was hope that the cost of living crisis was easing, some indicators, such as food prices, are moving in the wrong direction. Grocery price inflation rose to 4.3% in the four weeks to 22 February, up from 4% in January, according to Worldpanel by Numerator.
The Resolution Foundation analysed data from the Office for Budget Responsibility, finalised before the war began, indicating that a typical working-age household could be £300 better off over the next year. Unfortunately, the economic fallout from the Middle East conflict has the potential to completely erase these gains, underscoring the fragile state of UK finances.
