UK Inflation Reaches 3.3% in March as Iran War Drives Up Fuel Costs
The UK's inflation rate rose to 3.3% in the year to March, an increase from 3% in February, following a substantial jump in petrol and diesel prices. The Office for National Statistics (ONS) confirmed this rise was 'largely due to increased fuel prices', with airfares and food costs also contributing to the upward trend.
This data represents the initial official assessment of the Middle East conflict's impact on the UK's cost of living. Forecasts now suggest higher inflation for the year, with elevated energy costs potentially impeding economic growth as household and business spending power diminishes.
War's Immediate Economic Impact
Wholesale energy prices have escalated since the US-Israel coalition initiated strikes against Iran on 28 February. The conflict has disrupted energy production and transportation across the Middle East, leading to a slowing or cessation of operations due to ongoing missile and drone attacks. The ONS collected its March data mid-month, weeks after hostilities commenced.
Motor fuel prices saw an 8.7% month-on-month increase, the largest since June 2022. Annually, fuel prices rose by 4.9% to March, the highest since January 2023. Beyond fuel, ONS chief economist Grant Fitzner noted that rising airfares and food prices also played a role. Conversely, clothing costs offered 'the only significant offset', with prices rising less than in the previous year.
Food inflation climbed from 3.3% to 3.7% year-on-year in March, driven by chocolate, confectionery, meat, fish, and soft drinks. This could also be linked to the earlier timing of Easter this year.
Monetary Policy Implications
Prior to the conflict, the Bank of England was expected to reduce interest rates this year. However, the renewed threat of higher inflation has prompted speculation that the Bank may maintain current rates or even consider increases. The Monetary Policy Committee is scheduled to convene next week to review the current 3.75% rate. Chancellor Rachel Reeves acknowledged the war's impact, stating it was 'pushing up bills for families and businesses' and reaffirmed the government's commitment to 'keep costs down'.
Economists at PwC UK warned that this represents 'just the first wave of the energy shock', primarily affecting fuel prices at the pump, with potential knock-on effects for downstream products such as fertilisers, helium, plastics, and metals yet to materialise.
