US inflation to shake up FX?
Market overview
Global currency markets are approaching a critical turning point as investors reassess interest rate expectations, political risks and the sustainability of recent moves. The dollar remains close to its 2026 highs, although its five-week rally is showing signs of fatigue. The euro continues to struggle with French political uncertainty, while sterling's strength against the single currency masks a mixed performance elsewhere. Shifting bond yields, elevated energy prices and weaker equity markets are creating a more challenging backdrop, with traders increasingly questioning whether recent currency trends have further room to run.
Attention now turns to today's US inflation report, potentially the most important catalyst for FX markets this week. Brent crude near $105 a barrel continues to fuel inflation concerns, while pressure on technology stocks and tighter credit conditions are weighing on risk appetite. With expectations for further monetary tightening already reflected in market pricing, the scope for additional currency moves may increasingly depend on fresh economic surprises. A stronger inflation reading could reignite dollar demand, while softer figures may encourage a broader recovery in European currencies.
USD: Dollar rally faces its biggest test yet
The dollar remains near its 2026 highs, although its five-week rally is losing momentum as investors question whether further Fed tightening is already priced in. The greenback softened yesterday as stretched positioning and recovering global bonds encouraged profit-taking. Comments from Fed official John Williams added pressure by improving risk appetite rather than significantly altering rate expectations. Williams still anticipates another increase this year but sees inflation easing without further tightening in 2027.
Today's September CPI report will be pivotal. Headline inflation is forecast at 0.6% month on month, with core at 0.2%. A stronger reading could revive expectations of an October hike and lift the Dollar Index towards 103. Softer figures may reinforce expectations of a Fed pause, potentially exposing support near 101.5.
GBP: Sterling's euro strength masks a mixed outlook
Sterling continues to outperform the euro, with GBP/EUR up approximately 2% since September and reaching its highest level since June 2025. However, gains largely reflect euro weakness rather than underlying pound strength. GBP/USD has also recovered modestly from the low 1.32s as the dollar's rally loses momentum.
Looking ahead, persistent inflation and elevated energy prices are strengthening expectations of a potential Bank of England rate increase on 5 November, supporting sterling's yield appeal. The UK Budget on 28 October will also be closely watched, with markets looking for fiscal discipline and measures that preserve investor confidence.
EUR: Political uncertainty keeps the pressure on
The euro remains under pressure as French political instability and wider US-European yield differentials weigh on sentiment. EUR/USD has fallen around 4.3% from its September peak, briefly touching 1.1153 before recovering towards 1.1200. However, the rebound largely reflects dollar weakness rather than renewed confidence in the single currency.
With much of the French political risk potentially priced in, attention shifts to today's US inflation figures. Softer data could support a recovery towards 1.13 over the coming month, although stronger figures may trigger another test of the 1.1150 to 1.1160 support region.
Looking ahead
US inflation: September CPI takes centre stage today, with headline inflation forecast at 0.6% and core at 0.2% month on month. A hotter reading could renew dollar buying.
Federal Reserve: Markets will reassess the probability of an October rate increase, currently around 20%, alongside expectations for December.
EUR/USD: The 1.1150 to 1.1160 region remains key support, while a sustained recovery above 1.1200 could improve the near-term outlook.
GBP/EUR: Further gains will depend on continued euro weakness and growing expectations of tighter Bank of England policy.
UK Budget, 28 October: Fiscal measures and their implications for gilt yields could influence sterling sentiment.
Bank of England, 5 November: Persistent inflation and elevated energy prices could strengthen the case for another interest rate increase.
