GBP/USD Price Forecast: Turns flat after breakdown below 1.3400

Market impact: Mildly bearish GBP/USD, but with downside momentum temporarily pausing.

The break below the former rising trend-line support near 1.3495, combined with trading beneath the 20-period EMA around 1.3467, shifts the near-term technical structure in favor of sellers. The recovery toward 1.3385 appears more consistent with modest USD profit-taking than a confirmed sterling reversal. The RSI near 37.7 suggests weakening downside momentum, but it remains above oversold territory and does not yet provide a strong bullish signal.

The key market mechanism is the divergence between a softer dollar intraday and a still-hawkish US rates backdrop. Expectations that the Federal Reserve could deliver another rate hike this year support US yields and the dollar, limiting the ability of GBP/USD to sustain rebounds. If renewed USD strength pushes the pair below the recent low near 1.3336, the article identifies 1.3300 as the next downside area.

For sterling, the immediate catalyst is the UK flash S&P Global PMI release expected on Wednesday, September 23, 2026. A weaker-than-expected report would reinforce expectations of softer UK growth and increase pressure on GBP/USD. Conversely, a stronger PMI could produce a corrective rebound, but the technical bias would remain vulnerable unless the pair reclaims the 1.3467–1.3495 resistance zone.

The broader risk is that energy-market or geopolitical developments alter the US rate outlook. Higher oil prices could reinforce inflation concerns and Fed-hike expectations, favoring the dollar; a de-escalation or softer oil market could reduce that support. The US–Gulf discussions mentioned in the article therefore represent a short-term volatility catalyst rather than a durable sterling driver.

Trading implication:

the setup is bearish-to-neutral in the very short term—bearish while below the broken support zone, but vulnerable to a relief bounce because downside momentum is no longer accelerating. Confirmation would depend on whether GBP/USD holds above 1.3336, how UK PMI data changes BoE expectations, and whether US rate-hike pricing continues to strengthen.
