Deal or No Deal? Conflict Drives Oil Volatility and UK Inflation

The latest Iran conflict has once again shown how quickly energy markets can swing. After President Trump’s threat to target Iranian infrastructure, Brent surged past $100 per barrel, only to retreat below that psychological barrier within days. Such volatility feeds directly into business‑to‑business price surveys, with PMI data flagging rising cost pressures that will eventually filter to consumers. While the price gap between $100 and $99.99 may seem trivial, it has already rattled equity markets and heightened concerns about a broader energy‑driven inflation shock.

UK consumer price inflation held steady at 3% in February, but core CPI edged up to 3.2%, indicating sticky price dynamics once volatile energy and food items are stripped out. The Institute of Grocery Distribution warned that a prolonged Middle‑East flare‑up could push food inflation above 8%, adding roughly $188 to an average household grocery bill. Government officials have hinted at targeted support for heating‑oil users and a contingency plan for the new energy‑price cap, but details remain vague, leaving many households exposed to the looming energy shock.

Corporate earnings painted a mixed picture. Kingfisher’s focus on trade‑customers boosted DIY sales, delivering robust results despite a still‑soft housing market. Fintech challenger Revolut posted a record profit for 2025 and secured a UK banking licence, sparking speculation about a London IPO versus a US listing. Meanwhile, Estée Lauder and Pooch are negotiating a $40 billion merger, but cultural clashes and family‑shareholder consent could stall the deal. Retail confidence remains fragile, with the CBI’s weighted balance of sales volume plunging to –52 in March, the steepest decline since April 2020, underscoring the pressure on UK consumer spending.
