​UK CPI July 2025: trading sterling after inflation surprise​

Headline inflation masks underlying weakness in price pressures

​The July consumer price index (CPI) reading delivered an upside surprise that initially rattled markets, with core inflation climbing to 3.8% year-on-year (YoY) against expectations of 3.7%. This marks the highest level since early 2024 and represents a significant challenge to the Bank of England's (BoE) recent dovish pivot.

​However, traders need to look beyond the headline figure to understand the true inflationary landscape. The upside surprise was driven by just three narrow categories: airfares, hotels, and canteens. These sectors alone accounted for the entire overshoot, while the broader economy showed signs of cooling price pressures.

​Core goods inflation actually weakened materially, falling around 0.7% month-on-month (MoM). This suggests that the manufacturing and retail sectors are experiencing genuine disinflationary forces, potentially linked to weaker consumer demand and improved supply chains.

​Perhaps most tellingly, only 36% of the CPI basket is running above a 2.5% annualised pace. This distribution indicates that inflation is far from broad-based, with most sectors experiencing moderate price growth that aligns with the BoE's target trajectory.

Bank of England faces policy dilemma amid mixed signals

​The mixed inflation data presents the BoE with a complex policy puzzle. The headline reading of 3.8% provides ammunition for hawks who argue that interest rate cuts remain premature, especially given the central bank's recent shift towards a more accommodative stance.

​Yet the underlying composition of the data tells a different story. With core goods deflating and services inflation softening, the broader disinflationary trend appears intact. The narrow nature of the price pressures suggests temporary factors rather than persistent inflationary momentum.

​Market pricing for BoE rate cuts has become more volatile following the release. Traders are now questioning whether the central bank can maintain its dovish stance or if it will need to pause its easing cycle to address headline inflation concerns.

​The timing of this data release is particularly significant, coming just weeks before the BoE's next policy meeting. Policymakers will need to weigh the headline surprise against the encouraging underlying trends when considering their next move.

​GBP trading opportunities emerge from inflation volatility

​The British pound's reaction to the CPI data has created several trading opportunities across major currency pairs. Initial GBP strength on the headline surprise has given way to more nuanced price action as traders digest the underlying details.

​EUR/GBP also offers interesting dynamics, as the European Central Bank (ECB) continues its own policy normalisation process. The relative pace of rate cuts between the BoE and ECB could drive sustained trends in this cross, making it attractive for position traders.

​Traders considering these moves should familiarise themselves with how to trade forex before diving into these volatile conditions. The currency markets can move rapidly on central bank policy shifts, requiring proper risk management.

​Looking ahead to the next BoE meeting

​The upcoming BoE meeting will be critical for determining market direction over the coming months. Policymakers will need to balance the headline inflation surprise against the encouraging underlying trends when setting policy.

​Communication from BoE officials will be scrutinised for clues about their reaction to the mixed data. Any suggestion that they remain committed to their easing bias could trigger renewed GBP weakness and FTSE 100 strength.

​Conversely, signs that the central bank is concerned about the headline reading could support the pound while pressuring growth-sensitive UK stocks. The interplay between currency and equity markets will be particularly important to monitor.

​Traders should prepare for increased volatility around the meeting announcement. Having a clear view on potential scenarios and appropriate position sizes will be essential for navigating whatever decision emerges from Threadneedle Street.
