GBP/USD Price Forecast: Technical outlook

The GBP/USD extended its losses below 1.3300, opening the door for further downside. Sellers are eyeing August 27’s peak of 1.3266. In the short term, momentum shifted to be bearish, as portrayed by the Relative Strength Index (RSI), which aimed toward its neutral line. However, the RSI is still in bullish territory.

Once the GBP/USD clears the August 27 high, the next support would be the 1.3200 figure. On further weakness, the next stop would be the September 17 daily low of 1.3145, followed by the 1.3100 mark.

Conversely, for a bullish continuation, the GBP/USD must climb past 1.3300 and clear the top-trendline of the ascending channel at around 1.3380-90.
