GBPUSD could be the focal point on the final trading day of the next week. In the face of a potential global economic slowdown, gross domestic product numbers from the UK at 09:30 (the world’s 5th largest economy) could provide volatility ahead of US Consumer Price Index data out in the afternoon. Inflation is key for the pace at which the Federal Reserve will be hiking rates in 2019. Generally speaking, a high reading could be seen as positive (or bullish) for the USD, while a low reading could be seen as negative (or bearish).
From a technical point of view, we will be looking for a long position above 12820, alternative scenario sell position below 12680
