Sterling Weakens as BoE Easing Bets Rise

The inflation backdrop is doing the heavy lifting. The latest U.S. CPI forecast points to a 0.89% monthly rise in July, underscoring how sticky price pressures remain in the world’s largest economy, while UK inflation has eased to its lowest level since March 2025, according to the market context. For currency traders, that relative divergence is more important than the absolute level of inflation: weaker UK price momentum usually translates into lower yields and a softer pound, especially if the BoE is seen moving faster than the Fed.

Yields are reinforcing that view. The U.S. two-year Treasury note is around 4.205%, with the 10-year at 4.582%, levels that continue to offer the dollar an interest-rate cushion. Against that backdrop, sterling has been unable to sustain gains, even though FXB still trades above its 50-day moving average of 128.48 and its 200-day moving average of 127.81.

Momentum indicators suggest the move is losing steam rather than breaking down outright. FXB’s RSI has eased to 61.4 from 85.9 on July 15, while MACD remains positive at 0.3, pointing to a market that is still constructive but less stretched. Adalytica’s British pound trade signals show sentiment at 95, or “Extreme Greed,” even as awareness sits in “Fear,” a combination that often leaves the currency vulnerable to a pullback if incoming data fail to justify the optimism.

For investors, the message is straightforward: a softer UK CPI print would likely keep pressure on sterling, support dollar strength, and weigh on any pound-sensitive assets tied to the currency. The next catalyst is the next batch of UK inflation and labor data, which will shape whether the BoE can afford to move earlier than the Fed or whether the pound has to digest another leg lower.
