UK inflation has increased to 3.3% in the year to March, rising from 3% in February, after a sharp rise in petrol and diesel prices linked to the US-Israel conflict with Iran. The latest figures from the Office for National Statistics provide the first official indication of how the conflict in the Middle East is feeding into living costs in the UK.
The rise adds further pressure on households already dealing with elevated costs, with fuel once again playing a central role in overall inflation trends.
Fuel costs lead the rise in inflation
The ONS confirmed that the main driver behind the increase was higher motor fuel prices, alongside smaller contributions from airfares and food.
Fuel prices rose significantly in March, with petrol and diesel recording an 8.7% monthly increase, the largest jump since mid-2022 during the post-Ukraine invasion energy shock. On an annual basis, fuel costs were up 4.9%, marking the highest yearly rise since early 2023.
These increases reflect rising wholesale energy costs, which have surged since the conflict began at the end of February. Disruption to oil production and transport routes across the Middle East has contributed to volatility in global energy markets, feeding through to UK pump prices.
Other areas also pushing prices higher
While fuel was the dominant factor, food and travel costs also contributed to the overall rise in inflation.
Food inflation increased from 3.3% to 3.7% in the year to March, driven by higher prices for chocolate, confectionery, meat, fish and soft drinks. Some of this movement is also linked to seasonal demand around Easter, which can temporarily affect pricing patterns.
Airfares also rose, although the ONS noted this was partly due to the timing of Easter this year, which fell earlier than in 2025 and influenced travel data during the measurement period.
Clothing prices helped offset some of the upward pressure, rising more slowly than in the same period last year, which limited the overall increase in inflation.
Early signs of broader economic impact
Economists believe the inflation rise could be the beginning of a wider cost increase across the economy. Higher energy prices typically take time to filter through supply chains, meaning further pressure could emerge in the coming months.
Some analysts expect inflation could peak between 3.5% and 4% this year. While this remains well below the double-digit levels seen in 2022 during the Ukraine conflict, it is still significantly above the Bank of England’s 2% target.
The concern for policymakers is that higher energy costs could also slow economic growth, as households and businesses cut back on spending to absorb higher bills.
Interest rate outlook becomes less certain
The inflation data adds complexity to the Bank of England’s interest rate decisions. Rates currently sit at 3.75%, and expectations had previously leaned towards gradual cuts during 2026.
However, rising inflation could force policymakers to keep rates higher for longer, or in some scenarios reconsider further tightening if price pressures persist.
Central banks typically raise interest rates to reduce inflation by discouraging borrowing and spending. But if economic growth weakens at the same time, it creates a difficult balancing act for policymakers.
The Bank of England’s Monetary Policy Committee is due to meet next week, where it will review the latest economic data before making its next decision.
Government response to rising costs
Chancellor Rachel Reeves said the government recognises the pressure rising prices are placing on families and businesses. She stated that controlling living costs remains a key priority, alongside strengthening the UK’s long-term energy security.
She also indicated that the government would take steps to protect consumers from unfair price increases where possible, particularly in relation to essential goods such as food.
Political reactions to inflation rise
Opposition figures have argued that international events are not the only factor behind rising costs, pointing to domestic policy decisions as contributing pressures. Mel Stride said recent economic choices have left the UK more exposed to global shocks and called for changes to taxation and energy policy.
Other parties have focused on the broader cost-of-living crisis, suggesting that rising fuel and food prices are worsening financial strain on households that have already faced several years of high inflation.
Businesses and households feeling the impact
Economists warn that the latest inflation increase is only the first visible effect of higher energy costs, with further impacts expected in related sectors such as manufacturing, agriculture and transport. Rising input costs, including fuel, fertiliser and raw materials, may gradually filter through to consumer prices.
For households, the effects are already being felt at petrol stations, where fuel costs have increased noticeably in a short space of time. This has placed additional pressure on those who rely heavily on travel for work.
Self-employed workers and driving instructors, for example, have reported rising monthly fuel expenses, alongside higher maintenance and servicing costs linked to increased transport activity prices.
Outlook remains uncertain
With inflation rising again and energy markets remaining volatile, the outlook for the UK economy is increasingly uncertain. While price growth is still far below recent historical peaks, the direction of travel has shifted upwards once more.
The coming months will be crucial in determining whether this marks a temporary spike driven by geopolitical disruption, or the start of a more sustained period of inflationary pressure affecting households across the UK.
