Rising tensions and conflict in the Middle East have triggered a sharp surge in global energy prices, igniting an economic ripple effect that is already straining household budgets across the UK. With oil and gas prices rocketing, economists warn that inflation could climb far higher than anticipated, forcing the Bank of England to consider multiple interest rate hikes later this year.
Explosive Energy Price Increases Spark Inflation Concerns
The ongoing war in Iran has pushed the benchmark Brent crude oil price to approximately $110 per barrel, a dramatic increase from around $72 before the conflict erupted. This surge in oil costs is mirrored in the wholesale gas market, where prices have nearly doubled in just three weeks—from 77p per unit to a staggering 150p.
These soaring energy costs are fueling inflationary pressures across the economy. Thomas Pugh, chief economist at accounting firm RSM, now projects inflation could spike to 5% by year-end—more than double the previously expected 2% target.
Such a sudden rise in inflation threatens to erode consumers’ purchasing power, increasing the cost of essentials like heating and transportation. The Monetary Policy Committee has acknowledged this new economic shock, highlighting that rising fuel and utility prices will hit households directly and also push up costs for businesses.
Interest Rate Outlook Shifts Amid Inflation Surge
Against this backdrop, financial markets have rapidly adjusted their expectations for future interest rate movements. Just weeks ago, the consensus forecasted that borrowing costs would decline this year, with debates centered on the timing and scale of cuts.
However, prior to the Bank of England’s recent decision to hold the base interest rate steady at 3.75%, traders had shifted their outlook dramatically. The likelihood of an interest rate increase—once considered improbable—has now risen to about 3%, with markets pricing in a potential hike as soon as June 2026.
This pivot stems largely from expectations that the energy price cap will rise in June, reflecting the ongoing volatility in wholesale energy markets. Data from the London Stock Exchange Group indicates a razor-thin divide ahead of April’s rate-setting meeting, with a 51% chance of no change versus a 49% chance of a rate cut.
Looking further ahead, traders anticipate up to three interest rate hikes in 2026—potentially in June, July, and December—pushing the base rate up to 4.5% by year-end. This contrasts sharply with forecasts from earlier this month, which predicted a fall to 3.25%.
Not all economists agree on this trajectory. Pantheon Macroeconomics argues that if oil prices stabilize below $125 per barrel, the Bank of England may have enough flexibility to maintain the current rate without increases.
Consumers Already Feeling the Squeeze
Even before any official interest rate hikes occur, the ripple effects are evident. Mortgage rates have climbed sharply, hitting the highest levels in nearly a year. The average two-year fixed mortgage rate surged from 4.83% at the start of March to 5.3%, its peak since April 2025. Similarly, five-year fixed rates rose from 4.95% to 5.35%, levels not seen since August 2024.
These rising borrowing costs present a tough challenge for homeowners, especially those looking to remortgage or secure new loans. Higher rates translate into increased monthly payments, squeezing disposable income and dampening consumer spending.
Beyond mortgages, households face escalating energy bills as wholesale gas prices remain elevated. This dual pressure threatens to reduce overall economic growth by curtailing consumer demand and increasing business expenses.
Why This Matters: The Wider Economic Impact
The intersection of geopolitical conflict and economic policy has never been more apparent. The war in Iran has disrupted global energy markets, transforming a regional crisis into a global economic challenge. Rising inflation and potential interest rate hikes could slow economic recovery and increase financial strain for millions of Britons.
For the Bank of England, navigating this volatile environment will require balancing the need to control inflation without stifling growth. For consumers, the coming months may bring tougher financial choices as energy bills climb and borrowing costs rise.
Ultimately, this situation underscores the interconnectedness of global events and domestic economic health. The conflict’s far-reaching effects highlight the importance of resilient economic policies and cautious consumer financial planning.
As the year progresses, monitoring oil price movements and inflation data will be critical to understanding the full impact on interest rates and household finances.
