UK headline CPI eased to 2.6% year on year in June, which was 0.5 percentage points below the MPC’s April near-term projection of 3.1%. The shortfall was spread across food, core goods and services, and food inflation slowed to 1.7% year on year, the lowest in 15 months. Measures of domestic price pressure also cooled, but the data sit against a backdrop of renewed external cost risks.
Energy has re-emerged as a key variable for the inflation outlook. Crude oil prices rose after the collapse of the US-Iran ceasefire and fresh disruption to shipping via the Strait of Hormuz, while Ukrainian attacks on Russian refining capacity tightened diesel and refined product markets. The MPC said in June that risks to its energy-price view were skewed to the upside, and it is expected to revisit its assumptions and, as in April, set out alternative scenarios for a prolonged supply shock, even as such exercises can add uncertainty.
Short-Term Cooling Versus Rising Energy Risks
We recently saw UK headline inflation drop to 2.6% in June, which was lower than many expected, but we believe this cooling is only temporary. Given the mounting pressures in global energy markets, we expect inflation to quickly bounce back above the 3% mark in the coming weeks. This means derivative traders should prepare for 3% to become the new normal for UK inflation rather than the Bank of England’s official 2% target.
To support this view, we point to Brent crude oil prices, which have climbed back above $85 a barrel due to escalating tensions in the Middle East and ongoing strikes on refining infrastructure. Historically, a 10% sustained increase in energy prices tends to boost UK headline inflation by roughly 0.5 percentage points over the subsequent quarters. These supply-side shocks are highly likely to trigger second-round inflation effects as companies pass higher transport and manufacturing costs onto consumers.
Strategic Market Positioning Amid Persistent Inflation
For short-term interest rate (STIR) traders, this shifting outlook suggests that current market pricing for aggressive Bank of England rate cuts is misplaced. We recommend positioning for higher yields by shorting Sonia futures contracts expiring in late 2026, as persistent 3% inflation will force policymakers to keep interest rates elevated. Historically, when inflation consistently beats forecasts, the yield curve flattens as traders price out near-term monetary easing.
Additionally, we see a strong opportunity in buying UK inflation swaps, where the market is still underpricing this structural shift and expecting a rapid return to the 2% target. Derivative traders can also utilize call options on Brent crude to hedge against further shipping disruptions in the Strait of Hormuz. By positioning for higher-for-longer inflation and elevated energy volatility, traders can exploit the current mispricing in both fixed income and commodity markets.
