UK Inflation Rises to 3.3% in March 2026 as Middle East War Hits Fuel and Energy Costs

Britain's small and medium-sized businesses are facing fresh pressure after official figures revealed inflation eased to 3.3 percent in March, the first hard evidence of how the Middle East conflict is feeding into the real economy.

Data released by the Office for National Statistics on Wednesday showed that the Consumer Price Index grew from 3 percent in February, in line with City forecasts and marked the first increase in the headline rate since December. It is also the first inflation reading to capture a surge in global oil and gas prices since the outbreak of war two months ago, when Brent crude rose nearly 30 percent and traded around the $100-a-barrel mark for several weeks.

The pain at the pump was palpable. Petrol rose 8.6 pence a liter to 140.2p, the highest price since August 2024, while diesel, a mainstay of the freight and commercial transport sector, jumped 17.6p to 158.7p, the highest since November 2023. It equates to key operating costs and inputs.

Air fares added some heat, rising 10 percent month-on-month compared to a 0.3 percent fall in the same period last year. That is the biggest increase for February to March since 2016, although the ONS noted that prices were collected before the outbreak of war and increased for the period of long-haul flights immediately after Easter.

Grant Fitzner, chief economist at the ONS, said: “Inflation picked up in March, largely due to a rise in fuel prices, which led to their biggest increase in more than three years.

Economists at the International Monetary Fund and elsewhere have warned that the top rate could rise in the summer to more than 5 percent, more than double the Bank of England's two percent target. Core inflation, which strips out food and energy variables, eased to 3.1 percent from 3.2 percent, but services inflation, a measure closely watched by Threadneedle Street, edged up to 4.5 percent from 4.3 percent. Food prices were up 3.7 percent year-on-year, a number that will increase with the number of visitors.

The Bank of England's monetary policy committee is expected to leave the Bank rate unchanged at 3.75 percent when it meets next Thursday, although rate planners are facing a crisis. Martin Beck, chief economist at WPI Strategy, said: “With inflation likely to remain above target for a long time, the Bank of England is unlikely to cut rates anytime soon. But equally, the case for further tightening remains weak. A prolonged policy freeze looks the most likely outcome, leaving the economy exposed to a collision course and its impact on energy markets.”

Peter Dixon, senior economist at the National Institute of Economic and Social Research, went further, saying that the Bank “can't risk being complacent, so we expect there to be one defensive measure.” [quarter point] rate hike in the coming months.” A move like that would raise the cost of variable rate borrowing for millions of homeowners and small business owners, and set back those trying to get on the property ladder.

However, there are leaves of persistence. GDP grew by a stronger-than-expected 0.5 percent in February and unemployment unexpectedly fell to 4.9 percent in the three months to February, down from 5.2 percent, suggesting that, for now at least, the labor market is holding up despite external shocks.

Rachel Reeves, the chancellor, wrote words of sympathy: “This is not our war, but it is increasing the debts of families and businesses. That is why it is my main goal to keep costs down.” The Ministry of Finance has so far extended support to a limited number of rural households that rely on heating oil and has extended an existing program aimed at reducing energy bills for businesses, although SME lobby groups are already pushing for more aid targeted at firms whose fuel and transport costs cannot easily be passed on to customers.

For British SMEs, the immediate message from March's data is clear: strongly driven inflation is back, interest rate easing is further away than many expected, and the next phase of the Middle East conflict will do as much to correct the outlook for cash flows and investment as anything decided in Westminster.
