• GBP/USD struggles to lure buyers ahead of the crucial inflation data from the UK and the US.
• A combination of factors keeps the USD bulls on the defensive and lends support to the pair.
• The fundamental backdrop supports prospects for an extension of a one-week-old uptrend.

The GBP/USD pair ticks lower during the Asian session on Wednesday and moves away from over a two-week high, around the 1.2870-1.2875 region touched the previous day. The downside, however, remains cushioned as traders keenly await the release of the latest consumer inflation figures from the UK and the US.

The UK CPI will play a key role in influencing the Bank of England's (BoE) monetary policy decision and drive the British Pound (GBP). Apart from this, the crucial US CPI report will be scrutinized for cues about the Federal Reserve's (Fed) rate cut path, which, in turn, should provide some meaningful impetus to the US Dollar (USD) and help in determining the next leg of a directional move for the GBP/USD pair. 

Ahead of the high-impact macroeconomic data, the GBP might continue to draw some support from Tuesday's UK data showing a surprise drop in the unemployment rate. This, to a larger extent, overshadowed a jump in the number of people claiming unemployment-related benefits, by 135 K in July, and a sharp deceleration in the wage growth, from the 5.7% YoY rate to 4.5% during the three months to June.
