Sterling supported by rate rise as US midterms reshape the market
The latest US midterm elections and the ongoing Iran conflict are creating fresh uncertainty for currency markets as investors look towards the end of 2026 and into 2027. In this episode of Currency Exchange, Brian Daingerfield is joined by Paul Robson to discuss the implications of the Bank of England’s latest interest rate decision, the UK Budget and the surprisingly strong Democratic performance in the US midterms. They explore what the election result could mean for America’s AI investment boom, the outlook for oil prices and the dollar, and why Sterling has remained remarkably resilient despite a challenging global backdrop. Key points: 1. Bank of England turns more hawkish The Bank of England’s 25 basis point rate hike was more hawkish than markets had anticipated. The voting split, with eight members supporting a hike and one favouring a larger increase, suggested growing momentum towards tighter monetary policy. The Bank also indicated that further increases were likely, providing support for Sterling. 2. Sterling remains remarkably resilient Sterling’s trade-weighted index has reached its highest level since the UK’s EU referendum in 2016. Several factors have supported the currency, including its attractive carry position, equity inflows and a reduction in the UK’s perceived risk premium. Further improvements in Sterling’s relative yield advantage could provide additional support into 2027. 3. UK Budget postpones difficult fiscal decisions The UK Budget passed without significant market disruption, but questions remain about the longer-term fiscal outlook. Although it contained 98 policy changes, its immediate implications for growth, inflation and interest rates were limited. Attention will now turn to government borrowing, spending decisions and the potential political implications of postponing difficult choices until next year. 4. Democratic midterm victory puts AI investment under scrutiny The scale of the Democratic victory was greater than anticipated, raising questions about the future pace of US AI investment. Potential restrictions on data centre development at state and local level could challenge one of the main drivers of US economic exceptionalism, business investment and equity market performance. 5. Iran conflict and oil prices remain crucial market drivers The election result has reinforced pressure on the Trump administration to find a resolution to the Iran conflict. Expectations of a potential diplomatic breakthrough have helped push oil prices lower, improving the outlook for risk assets. However, the persistence of higher energy prices remains an important consideration for central banks and inflation expectations. 6. Dollar outlook remains tilted to the downside Despite the potential for increased safe-haven demand during periods of market volatility, Brian maintains a negative medium-term outlook for the dollar. A moderation in US AI investment could reduce the exceptional growth and investment advantage that has supported the currency. Expectations of less aggressive Federal Reserve tightening also reinforce the downside risks.
