Oil surge fuels dollar rally as global FX markets come under pressure

Market overview

Currency markets are ending the week on a cautious footing, with shifting interest rate expectations, rising energy costs and renewed political uncertainty driving a clear divergence between the major currencies. The US dollar continues to attract demand as investors favour its yield advantage, while the euro struggles under mounting fiscal pressures and sterling remains caught between attractive interest rate differentials and deteriorating global risk appetite. Higher bond yields and concerns over inflation are complicating the outlook for central banks, leaving FX markets increasingly sensitive to economic data and geopolitical developments. With volatility building across energy and sovereign debt markets, the next move in currencies could prove more decisive than the relatively contained trading ranges suggest.

The dollar is on course for its fourth consecutive weekly advance, supported by hawkish Federal Reserve minutes and growing expectations of another rate increase before year-end. Meanwhile, renewed disruption risks in the Strait of Hormuz have pushed Brent crude towards $104 a barrel, threatening to reignite inflationary pressures. European markets face a different challenge, with France's deteriorating fiscal outlook unsettling bond investors and weighing on the single currency. The combination of tighter financial conditions, geopolitical uncertainty and diverging central bank expectations continues to favour defensive positioning, with the dollar looking best placed to benefit.

USD: Federal Reserve expectations keep the dollar in control

The dollar remains firmly supported after September's Federal Reserve minutes reinforced concerns that monetary policy may not yet be restrictive enough to contain inflation. Markets now assign an 80% probability to a December rate increase, helping lift the US 10-year Treasury yield to 5.25% and the two-year to 4.77%. Although Governor Christopher Waller's more measured comments on the timing of further tightening prompted some consolidation, the broader interest rate outlook continues to favour the greenback.

The Dollar Index (DXY) is trading around 102, with resistance between 102.5 and 103. A sustained move above 103 would strengthen the argument for another leg higher, while 101.5 provides initial support. Elevated energy prices and a fragile global bond market are reinforcing the dollar's appeal, although the next decisive move will likely depend on inflation data.

Attention now turns to today's University of Michigan consumer surveys, where inflation expectations are forecast to rise despite softer consumer confidence. Next Wednesday's US CPI release represents the more significant test, with annual inflation expected at 3.6%. A stronger reading could cement expectations of a December increase and propel the dollar towards fresh highs. Conversely, softer inflation could ease Treasury yields and trigger some profit-taking. For now, the near-term outlook remains constructive, with the balance of risks favouring further dollar strength.

GBP: Sterling holds its ground as global pressures build

Sterling continues to demonstrate resilience, although its ability to advance remains constrained by a stronger dollar and increasingly cautious investor sentiment. Attractive UK interest rate differentials are providing some support, but rising energy prices and tighter global financial conditions are limiting demand for risk-sensitive currencies. With few fresh domestic catalysts, the pound remains largely at the mercy of developments overseas.

GBP/USD continues to trade around 1.32, maintaining the unusually narrow range that has characterised much of 2026. Despite recent downward pressure, the pair has yet to establish a convincing move outside its established boundaries, highlighting sterling's ability to absorb wider market volatility. However, a further rise in US Treasury yields could test that resilience, particularly if incoming inflation figures reinforce expectations of additional Federal Reserve tightening.

Against the euro, sterling's position remains more encouraging. GBP/EUR has retreated below 1.18 following a rally towards levels rarely sustained over the past decade. However, the inability to consolidate above this threshold suggests that recent gains have been driven more by European weakness than renewed confidence in the UK outlook. Further progress may therefore depend on another deterioration in eurozone sentiment, while GBP/USD remains vulnerable to the dollar's broader momentum.

EUR: French fiscal concerns deepen the euro's difficulties

The euro remains one of the more vulnerable major currencies, with EUR/USD trading close to its weakest levels since May 2025. Political uncertainty, widening sovereign bond spreads and an increasingly unfavourable interest rate outlook are undermining investor confidence. Although technical indicators suggest that selling pressure may be becoming overstretched, the fundamental picture offers little encouragement for a sustained recovery.

France remains central to the market's concerns, as difficult budget negotiations and questions surrounding the country's debt trajectory continue to unsettle investors. The spread between French and German government bond yields has widened to levels not seen since 2012, reviving concerns over financial fragmentation within the eurozone. These pressures are increasingly overshadowing relatively resilient economic data, leaving the single currency exposed to further political and fiscal developments.

The European Central Bank is providing limited relief. September's meeting minutes revealed continued concern about inflation, but also highlighted the potential damage that elevated borrowing costs could inflict on economic growth. This more cautious policy balance has reduced expectations of additional tightening, particularly when compared with the Federal Reserve's more aggressive stance.

With EUR/USD hovering around 1.12, the immediate outlook remains challenging. Elevated oil prices, French sovereign debt concerns and the dollar's yield advantage continue to restrict upside potential. A short-term rebound is possible given stretched positioning, but without a meaningful improvement in European bond markets, any recovery is likely to struggle for momentum.

Looking ahead

• Friday, 9 October: US consumer sentiment. The University of Michigan surveys will provide fresh insight into inflation expectations and household confidence, with implications for near-term dollar sentiment.

• Federal Reserve commentary: Remarks from Susan Collins will be closely monitored for further indications of the Fed's willingness to raise interest rates in December.

• Wednesday, 14 October: US inflation. CPI is expected to reach 3.6% annually. An upside surprise could strengthen the dollar, while a softer reading may offer relief to GBP/USD and EUR/USD.

• European fiscal developments: French budget negotiations and sovereign bond spreads remain critical for euro sentiment. Further instability could provide additional support for GBP/EUR.

• Middle East tensions and oil prices: Developments around the Strait of Hormuz could drive renewed energy volatility, influencing inflation expectations, bond yields and global risk appetite.

• Key FX levels: Watch DXY resistance at 102.5 to 103, GBP/USD around 1.32, GBP/EUR at 1.18 and EUR/USD near 1.12 for indications of the next directional move.
