British Pound Price Chart – GBP/USD Weekly

Chart Prepared by Michael Boutros, Sr. Technical Strategist; GBP/USD on TradingView

Technical Outlook: In last month’s British Pound Weekly Forecast we noted that, “a six-day sell-off rebounded off support on Friday with an outside-day reversal. From a trading standpoint, the immediate focus is on this recovery…” GBP/USD rallied nearly 3.5% in the following weeks with price exhausting into the 75% parallel of the ascending pitchfork extending off the 2023 low. A pullback of more than 1.9% off those highs reversed course this week with the post-NFP rally snapping a two-losing streak on Friday.  

Weekly resistance remains along the 75% parallel and is backed by the 2025 high-week close (HWC) / 78.6% retracement of the June decline at 1.3648/50- look for a larger reaction there IF reached with a breach / weekly close above the 2022 high at 1.3749 ultimately needed to mark resumption of the broader uptrend. Subsequent resistance objectives eyed at the upper parallel / 61.8% extension of the 2022 advance at 1.4003.

Initial weekly support rests at with the 2024 swing high at 1.3434 and is backed by 1.3280-1.3315- a region defined by the July low-week reversal close and the 61.8% retracement of the July advance. Note that the median-line converges on this threshold in the coming weeks and a break / close below this slope would suggest a more significant high is in place / a larger reversal is underway. Subsequent support objectives seen at 1.3092-1.3144 and the 100% extension at 1.2948 in the event of a break.

Bottom line: Sterling failed a third attempt to break support this week with the September opening-range taking shape just above- look for a breakout of this week’s range in the days ahead. From a trading standpoint, losses should be limited to the median-line IF price is heading higher on this stretch with a breach / close above 1.3650 needed to fuel the next leg of the advance.

Keep in mind we get the release of key US inflation data next week with Core PPI & CPI on tap Wednesday and Thursday respectively. Stay nimble into the releases and watch the weekly closes for guidance here. Review my latest British Pound Short-term Outlook for a closer look at the near-term GBP/USD technical trade levels.
