Technical Analysis

Since establishing a bottom at 1.27078 on April 7, GBPUSD has been maintaining a well-defined upward trajectory characterized by a sequence of higher highs and higher lows. The initial trend reversal was confirmed by price action decisively closing above the 50-period Exponential Moving Average (EMA) and subsequently the 20-period EMA repositioning the GBPUSD in upward trajectory.

Momentum indicators continue to reinforce the bullish outlook. The Momentum Oscillator remains anchored above the 100 baseline, while the Relative Strength Index (RSI) holds above the neutral 50 mark, both suggesting sustained upward momentum.

That said, a negative divergence emerging between price action and the Momentum Oscillator warrants caution. This divergence could signal a potential near-term correction before the broader bullish trend resumes.

Potential Upside Targets  

Should the bulls maintain market control, traders may direct their attention toward the four potential resistance levels below:

1.36019: The initial resistance is 1.36019, which aligns with the weekly resistance, R3, estimated using the standard methodology.

1.39315: The second price target is identified at 1.39315, corresponding to the 261.8% Fibonacci Extension drawn from 1.34427 to 1.31393.

1.42341: The third target is established at 1.42341.

1.44211: An additional price target is estimated at 1.44211, which corresponds to the 423.6% Fibonacci Extension drawn from 1.34427 to 1.31393.

Potential Downside Targets  

Should the sellers take market control, traders may consider the four potential support levels listed below:

1.32604: The first level of support is identified at 1.32604, representing the weekly Pivot Point, PP, estimated using the standard methodology.

1.31393: The second support level is 1.31393, reflecting the daily low from May 12.

1.30142: The third support level is identified at 1.30142, corresponding to the peak marked March 20.

1.29404: An additional downward target is observed at 1.29404, corresponding to the weekly support, S3, estimated using the standard Pivot Point methodology.

Fundamentals

UK inflation accelerated in April, with the Consumer Prices Index including owner occupiers' housing costs (CPIH) rising 4.1% year-on-year, up from 3.4% in March. The standard CPI also climbed to 3.5% from 2.6% the previous month. On a monthly basis, both CPIH and CPI increased by 1.2%, a sharp rise compared to April 2024.

The main upward pressures came from housing, transport, and recreation costs, partially offset by a fall in clothing and footwear prices. Core inflation also rose, with core CPIH up to 4.5% and core CPI at 3.8%, reflecting persistent price pressures in services and an uptick in goods inflation.

Conclusion

With inflation surprising to the upside and a full slate of PMI and retail data ahead, markets are entering a pivotal stretch that could redefine expectations for growth and monetary policy. GBPUSD remains technically supported by a well-structured uptrend, but signs of negative divergence suggest that bullish momentum may face short-term headwinds. Traders should remain nimble, balancing the prevailing upward bias with heightened sensitivity to incoming data and potential volatility around key event risks.
