GBP/USD Price Analysis: Technical outlook

After a five-day consolidation that witnessed the GBP/USD hitting a yearly peak of 1.3044, followed by a tall bearish candle that sent the pair drifting from around 1.3000s toward the 1.2940 mark before tumbling deeper, toward the 1.2900 figure.

Momentum, as depicted by the Relative Strength Index (RSI), remains bullish, but in the near term, sellers have moved in, as the RSI slope aims downwards.

Therefore, the GBP/USD could continue to edge lower, but first, market participants need to push the exchange rate below 1.2900. In that outcome, the next support could be the June 12 high at 1.2860, followed by July 10 low at 1.2779. A further downside is seen at the 100-day moving average (DMA) at 1.2678.
