UK Inflation Rises to 3.3% as Iran Conflict Pushes Energy Costs Higher

Consumer prices in the United Kingdom rose at a faster pace in March, with annual inflation climbing to 3.3% from 3% the previous month, as escalating conflict in Iran triggered a sharp increase in energy costs.

The latest figures from the Office for National Statistics matched expectations but have led markets to rethink the likelihood of an imminent interest rate cut by the Bank of England, which now appears increasingly unlikely.

The rise in inflation was driven primarily by a surge in fuel prices, with petrol and diesel costs jumping 8.7% over the month. This marks the steepest increase since the summer of 2022, when global energy markets were disrupted following Russia’s full-scale invasion of Ukraine.

The impact of higher fuel costs has extended beyond petrol stations, feeding into broader areas of the economy, including airfares and food prices, and adding to the pressure on households and businesses.

UK Treasury chief Rachel Reeves acknowledged the international roots of the issue, noting that although the conflict is not domestic, it is directly increasing costs for families and companies across Britain.

Lindsay James, an investment strategist at Quilter, underscored the significance of the latest data, stating, "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 global equity markets have shown some signs of recovery, the physical oil market—particularly supply flows into Europe—remains under intense strain. Analysts suggest that reopening the Strait of Hormuz would be critical to easing supply constraints and reversing the upward pressure on prices, though the geopolitical situation remains highly uncertain.

The timing of the inflation increase presents a significant challenge, as it coincides with signs of weakening in the domestic economy. Recent labour market data points to falling payrolled employment and rising economic inactivity, while wage growth has begun to slow.

For many workers, the combination of rising living costs and easing earnings growth is eroding real purchasing power.

For the Bank of England, the renewed inflationary pressure complicates its policy outlook.

Prior to the escalation of the Iran conflict, there had been growing expectations that the central bank would begin cutting interest rates this spring, with its main rate projected to fall from 3.75% as inflation moved closer to the 2% target. However, with inflation now expected to potentially reach 4% in the coming months, policymakers face a more difficult decision at their upcoming meeting.

There is also increasing debate among economists about whether raising interest rates would be an effective response to the current situation. As James explained, "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 perspective suggests that the Bank of England may opt to keep interest rates on hold for now, choosing to monitor whether rising prices begin to feed into wage growth before taking further action.
