GBP/USD Price Forecast: Technical outlook

The GBP/USD uptrend remains questionable as the pair has dropped below the 20-day SMA at 1.3590, but so far is clinging above the 50-day SMA at 1.3492. Momentum indicates that bears have the upper hand, as depicted by the Relative Strength Index (RSI).

That said, a daily close below 1.3500 could pave the way for further GBP/USD losses. The first support is 1.3500, followed by the 50-day SMA. A breach of the latter will expose 1.3400 and the 100-day SMA at 1.3248. On the flipside, if the pair stays above 1.3500, buyers need to surpass the 20-day SMA to challenge 1.3600.
