The cost of living in the UK accelerated throughout March, propelled by a significant increase in petrol and diesel prices following the outbreak of the Iran war.

According to the Office for National Statistics, the annual consumer price inflation rate moved to 3.3% from 3% the previous month, a shift that matched the forecasts.
This inflationary pressure is largely attributed to an 8.7% monthly jump in motor fuel costs, which represents the sharpest rise seen since the summer of 2022, following Russia’s full-scale invasion of Ukraine.
Beyond the petrol stations, the fallout from higher energy prices has trickled down into airfares and food supplies, complicating the economic landscape for the government and the Bank of England.
UK Treasury chief Rachel Reeves noted that while the conflict is not a domestic one, it is directly pushing up bills for families and businesses across Britain.
Lindsay James, an investment strategist at Quilter, observed that “this morning’s inflation data showed CPI creeping back up to 3.3%, confirming that price pressures are re-accelerating rather than fading away since the outbreak of the war in Iran.”
While international markets have shown some signs of recovery in equity prices, the physical market for oil delivery into Europe remains under immense strain.
Experts suggest that a swift reopening of the Strait of Hormuz is the only viable path to unwinding the current inflationary trend, yet the situation remains volatile and unpredictable.
The Bank of England’s policy dilemma
The timing of this inflation surge is particularly problematic because it coincides with a period of cooling in the domestic economy.
Recent data from the labour market indicates that payrolled employment is falling and economic inactivity is on the rise, while wage growth has started to ease.
For the average British worker, the combination of rising essential costs and stagnating earnings growth creates a challenging environment for real purchasing power.
As for the Bank of England, this sudden spike in prices has disrupted the projected path of beginning to lower borrowing costs this spring.
Prior to the escalation of the Iran war, there was a growing consensus that the central bank would reduce its main interest rate from 3.75% as inflation appeared to be heading back toward the official 2% target.
However, with inflation now expected to potentially hit 4% in the coming months, the Monetary Policy Committee faces a much more difficult decision during its meeting next week.
There is a growing debate among economists regarding whether traditional interest rate hikes are the correct tool to address this specific crisis.
According to James “a rise in rates risks misdiagnosing the problem. This inflationary pulse is being driven by supply disruption, not excess demand. Higher interest rates will do nothing to increase the flow of oil or other goods from the Middle East.”
This sentiment suggests that the Bank of England may choose to maintain its current stance, keeping rates on hold while monitoring whether these price increases begin to manifest in higher wage demands across the broader economy.
