UK Inflation Climbs to 3.3% as Iran War Lifts Energy Costs

BBC Business reported Wednesday that UK inflation accelerated to 3.3% in the year to March, up from 3.0% in each of the two prior months and firmly above the Bank of England’s 2% target.

The figures mark the first official inflation reading since a US-Israel military conflict with Iran broke out, driving energy and fuel costs sharply higher across global markets.

Fuel, Food and Fares Drive the March Increase

The Office for National Statistics attributed the March pickup primarily to higher fuel prices. Rising airfares and increased food costs also contributed to the acceleration.

Food price inflation climbed from 3.3% to 3.7% over the same period. Chocolate, confectionery, meat, fish and soft drinks all recorded notable price rises, with Easter timing cited as a partial factor.

The Food and Drink Federation has warned that food inflation could reach as high as 10% by year-end, reflecting supply chain pressures that can take up to 13 months to filter through to shop shelves.

Background: From 11% Peak to a Complicated Recovery

UK inflation peaked at 11.1% in October 2022, the highest level in four decades, driven by pandemic-era energy demand and Russia’s invasion of Ukraine.

The Bank of England subsequently lifted its benchmark rate to 5.25% to cool price growth. Since August 2024, policymakers had delivered six consecutive cuts, bringing rates down to 3.75%.

Official forecasts published alongside Chancellor Rachel Reeves’ Spring Statement in March had projected inflation returning to near the 2% target over the coming five years. Those projections predated the Iran conflict entirely.

Rate Path Now Uncertain as War Risk Looms Large

The Bank of England has since cautioned that inflation could spike to as high as 6% in a worst-case scenario tied to the conflict. That warning has effectively put further rate reductions on hold.

Core CPI, which strips out volatile food and energy items, eased slightly to 3.1% in March from 3.2% in February. Policymakers watch this measure closely when assessing underlying price momentum.

Adding to the inflationary mix, businesses are absorbing higher staffing costs following increases to employer National Insurance contributions and the minimum wage. Companies facing those pressures are more likely to pass costs on to consumers, reinforcing the inflation cycle.

The Bank faces a difficult balancing act. Raising rates risks slowing an already sluggish economy and squeezing mortgage holders. Holding or cutting risks allowing inflation to become further entrenched.
