Indicator Background British Preliminary GDP is a key economic indicator, and provides an excellent indication of the health and direction of the British economy. Traders should pay close attention to the GDP release, as an unexpected reading could affect the direction of GBP/USD.

The estimate for Preliminary GDP in the Q2 report stands at 0.3%. Sentiments and levels Last week’s strong  housing and job numbers have increased speculation about a rate hike by the Fed, perhaps as early as September. All eyes will be on the Fed policy statement later this week, as any hints about a rate hike could help the US dollar rally even higher against the pound.  So, the overall sentiment is  bearish on GBP/USD towards this release. Technical levels, from top to bottom: 1.5769, 1.5682, 1.5590, 1.5485, 1.5341, and 1.5269. 5 Scenarios Within expectations:  0.0% to 0.6%. In such a scenario, GBP/USD is likely to rise within range, with a small chance of breaking higher. Above expectations: 0.7% to 1.0%: An unexpected higher reading can push the pair above one resistance line. Well above  expectations: Above 1.0%: A surge in the reading would  push  the pound higher  and the pair could break a second line of  resistance as a result. Below expectations: -0.4% to -0.1%: In this scenario, GBP/USD could drop below one support level. Well  below  expectations: Below -0.4%. A sharp contraction  could hurt the  pound, and the pair could fall below a second level of support. For more on the pound, see the GBP/USD forecast.
