Iran War Begins to Fuel Inflation as Pay Awards Ease

Why It Matters

Geopolitical tension is reigniting inflation pressures, tightening household finances while moderating wage growth, which could shape Bank of England policy and government support decisions.

Key Takeaways

• UK CPI rose to 3.3% YoY in March, driven by fuel
• RPI reached 4.1% in March, the highest since 2022
• Median basic pay award slipped to 3.2% in April
• Statutory wage hikes absorb larger share of pay budgets
• Economists warn inflation may stay elevated through year

Pulse Analysis

The escalation of the Iran‑Israel conflict has quickly filtered into the United Kingdom’s price landscape. Fuel prices posted their steepest three‑year rise, pushing the consumer‑price index (CPI) to 3.3 % year‑on‑year in March, while the retail‑price index (RPI) climbed to 4.1 %. ONS chief economist Grant Fitzner highlighted air‑fares and food as secondary drivers, echoing the CBI’s warning that the energy shock will keep household bills under pressure. Although the surge is milder than the 2022 post‑Ukraine‑war spike, the upward bias remains firmly tilted to the upside.

At the same time, the labour market is showing signs of restraint. Brightmine’s data reveal a median basic pay award of 3.5 % for the quarter ending March, but the figure slipped to 3.2 % in April as employers grapple with higher statutory minimum‑wage obligations that took effect on 1 April. The mandatory National Living Wage increase and sector‑specific uplifts are consuming a larger slice of pay budgets, leaving less room for discretionary raises. With a still‑softening job market, firms appear to be prioritising affordability over aggressive wage growth.

Policymakers now face a delicate balancing act. The Bank of England could afford a modest pause in rate hikes if the labour market remains weak, yet persistent inflation above the 2 % target may force tighter monetary policy later in the year. The Treasury is under pressure to roll out targeted energy‑bill support for vulnerable households, especially as food price pass‑throughs are expected to materialise over the next twelve months. Overall, the convergence of geopolitical risk, stubborn price pressures, and cautious wage growth suggests a protracted period of economic uncertainty for the UK.
