Pound Retreats as Markets Watch UK CPI and Fed Rate Call

Key Moments

GBP Under Pressure Ahead of Key Central Bank Events

GBP/USD slips toward 1.3470 in early Asian trading on Wednesday, with the British Pound losing ground against a strengthening US Dollar. The move reflects positioning ahead of two major catalysts later in the day: the UK August Consumer Price Index (CPI) release and the Federal Reserve’s interest rate decision.

Dollar strength is being underpinned by expectations that the Federal Reserve will raise interest rates, as investors adjust to the prospect of tighter US monetary policy. The GBP/USD pair has eased below the 1.3500 mark, with traders cautious as they await fresh policy and inflation signals from both sides of the Atlantic.

Fed Expected to Hike as Energy Costs Lift Inflation

Market participants are increasingly confident that the Fed will deliver a 25 basis point increase to its benchmark rate at its September policy meeting on Wednesday. The anticipated move is seen as a response to higher energy prices, which have contributed to a stronger-than-expected rise in underlying inflation in August.

“While markets are prepared for a hike, investors should remain on alert for any surprises,” said Juan Perez, senior director of trading at Monex USA in Washington.

“You have to be prepared for the unexpected … this is a time of volatility,” Perez said, adding that given Fed Chair Kevin Warsh’s aversion to forward guidance, it was not unthinkable that the US central bank may choose to hold rates.

UK Inflation Data Poised to Shape BoE Outlook

Attention is also firmly on the upcoming UK inflation figures. August CPI is forecast to rise by 3.1% from a year earlier, compared with 2.9% in July. Core CPI is projected to increase by 2.6% year-on-year in August, the same pace as previously. The data will be a critical input for the Bank of England (BoE) as it prepares for its interest rate decision on Thursday.

The BoE is expected to keep its policy rate unchanged at 3.75% in September. However, a rate increase to 4% is anticipated before the end of the year as inflation pressures accumulate.

Strategists See CPI as Key Near-Term Driver for Sterling

Strategists at Scotiabank highlight that the coming UK inflation release is the main short-term catalyst for the Pound, calling the CPI data “the weekly data highlight.” Even so, they argue that the report is “unlikely to force policymakers to unexpectedly hike on Thursday,” supporting the consensus that the BoE is likely to maintain current policy settings at this week’s meeting unless there is a major surprise in the figures.

Technical Picture: Support Cluster Around the 100-Day Moving Average

On the daily chart, GBP/USD is trading just above the 100-day moving average and the lower Bollinger Band, forming a modest area of technical support. Despite this, the pair remains below the middle Bollinger Band, which is capping the broader upside tone. The 14-period Relative Strength Index hovering near 42 points to waning bullish momentum and a slight bearish tilt in the near term, with price consolidating within the Bollinger Bands.

On the upside, initial resistance is located at the middle Bollinger Band near 1.3550, followed by a more significant ceiling at the upper Bollinger Band around 1.3660, where sellers may re-emerge if the pair stages a stronger rebound. On the downside, immediate support sits just below current levels at the 100-day moving average around 1.3445, backed up by the nearby lower Bollinger Band near 1.3440. A clear break beneath this support zone would open the way for a deeper retracement within the broader range.
