The short-term bias for GBPUSD is bearish after the pair fell below the daily Ichimoku cloud and below the 50-day moving average. Momentum indicators are also turning bearish with the RSI falling below 50. Support should come around the 200-day moving average around 1.5360. Resistance is at 1.5818.
In the bigger picture, GBPUSD remains neutral after the rebound from 1.4564 to 1.5929. We would need to see a break below the key psychological level of 1.5000 to see a shift back to the downtrend that began from 1.7190 in July 2014 to 1.4564.
