British Pound: Range-bound against US Dollar ahead of Budget – Scotiabank

Market impact: Mixed, with a short-term neutral-to-slightly bullish bias for GBP/USD.

GBP/USD is being supported by improved political sentiment following the leadership transition, but that support is being offset by softer UK–US yield spreads. The latter is important because narrowing rate differentials reduce the relative carry advantage of sterling and make sustained upside harder without stronger UK data or a more hawkish Bank of England outlook.

The immediate implication is consolidation rather than a decisive trend move. With limited UK data and little BoE communication during August, volatility is likely to remain event-driven. Scotiabank identifies a near-term range around 1.3600–1.3700, while noting that the broader technical structure remains constructive after the late-July rally. A move above the upper end of that range would require renewed yield support, broad US-dollar weakness, or further improvement in UK political risk sentiment.

The more significant medium-term risk is fiscal policy. The October 28, 2026 Autumn Statement could materially alter expectations for UK borrowing, gilt yields, inflation, and BoE policy. A credible, growth-supportive budget could reinforce sterling by reducing political and fiscal-risk premia. Conversely, measures implying larger deficits, heavier taxation, or weaker growth could pressure GBP through higher risk premia—even if gilt yields rise—because markets may interpret the move as deteriorating fiscal quality rather than improved monetary support.

For traders, the key distinction is whether higher UK yields arise from better growth and policy credibility or from increased fiscal stress. The former would tend to support GBP/USD; the latter could weaken sterling and increase downside volatility. The pair’s relatively elevated RSI, just below the overbought threshold, also suggests that upside may be vulnerable to profit-taking unless fundamental support improves.

What to monitor next:

UK gilt–Treasury yield spreads, BoE guidance, UK inflation and labor data, US rate expectations and dollar momentum, and early details or market reaction surrounding the October 28 budget. Until one of these catalysts changes the rate or fiscal-risk outlook, the impact remains predominantly range-bound and mixed.
