US Dollar Surges in September as Euro Lags, Fed-ECB Rate Divergence in Focus

The Quick Take

• The US dollar posted strong gains throughout September 2026, with the Business Times Singapore noting the euro has lagged significantly as investors reassess the Fed-ECB rate differential.
• Key drivers for USD/EUR direction remain expectations for Federal Reserve and European Central Bank rate policy, with the Fed maintaining a relatively tighter stance.
• A surging dollar creates global ripple effects — tightening financial conditions for emerging markets, raising commodity import costs, and pressuring Asian central banks managing currency stability.

The US dollar posted a notable surge through September 2026, ending the month as the dominant performer among major currencies while the euro lagged behind. Business Times Singapore reported that the key drivers for the common currency's performance are tied to expectations for Federal Reserve and European Central Bank policy, a divergence that has been widening as the US economy continues to show resilience while Europe faces energy and fiscal headwinds. The dollar index's September strength reflects a reassessment by currency markets of the depth and pace of US rate cuts relative to the more aggressive easing path being priced for the ECB.

The consequences of sustained dollar strength are broad across global financial markets. Asian central banks, including the Bank of Japan, Bank of Korea, and Monetary Authority of Singapore, face increased pressure to defend their currencies or accept the imported inflation that comes with dollar appreciation. For Singapore specifically, the strong dollar affects MAS's exchange rate-based monetary policy framework, which targets the SGD nominal effective exchange rate rather than a policy interest rate. Commodity-importing economies face higher energy and food bills denominated in dollars, which risks reactivating inflation that central banks had been working to suppress throughout 2025-2026.

The forward catalysts for dollar direction include the US PCE inflation data released September 30, the October non-farm payroll report on October 4, and the Federal Reserve's next FOMC meeting. A hot PCE print would further cement dollar strength by pushing back Fed rate cut expectations. For the euro, the ECB's October meeting guidance will determine whether EUR/USD can recover from its September underperformance. Singapore investors with offshore USD assets have benefited from September's dollar surge, but those with dollar-denominated liabilities or imports face rising costs that will flow through to corporate margins in the coming quarter.
