FX.co ★ GBP/USD Forecast for September 15, 2025

On the daily chart, the British pound has consolidated above the MACD line. With the Marlin oscillator developing in the positive zone, the target at 1.3631 becomes relevant.

However, this outlook may be deceptive, since the signal line of the Marlin oscillator is at the upper boundary of the descending channel. A downward movement is possible, even breaking below its lower boundary. A move and consolidation below the 1.3525 level would also mean consolidation below the MACD line, making the 1.3364 target realistic rather than a false one (as opposed to 1.3631).

On the four-hour chart, the price remains within the range of the September 9–11 extremes and the MACD line (1.3493–1.3589), with upward pressure. However, the Marlin oscillator is not advancing (not growing), instead maintaining a wait-and-see stance on the zero neutral line (anticipating the Fed meeting).
