GBP/USD Price Analysis: Technical outlook

After hitting a three-month high at 1.2860, the GBP/SD dropped more than 100 pips and cleared a support trendline drawn from lows of May 17 that passes at around 1.2730.

Although momentum favors buyers with the Relative Strength Index (RSI) above the 50-neutral line, the major has failed to sustain the uptrend above 1.2800.

Risk events, like the latest inflation report, could not lift the GBP/USD close to 1.2800. That, along with Thursday’s Bank of England decision, will keep the pair trading volatile in the upcoming days.

Key resistance levels lie at 1.2739, the current week’s high, followed by 1.2800. Once cleared, the next stop would be the monthly high of 1.2860.
