The US dollar climbed to an 18-month high in trading on Wednesday (November 11), marking a sharp surge that has unfolded over the past two months. The Bloomberg Dollar Spot Index rose by as much as 0.4%, reaching its strongest level since May 2025, with the dollar outperforming all other major currencies.
This strengthening is primarily driven by growing expectations that the Federal Reserve will raise interest rates again in December. Market participants have even begun to factor in the possibility of a 50-basis-point hike, although the prevailing baseline scenario still points toward a smaller increase.
Expectations for monetary tightening have intensified following US consumer inflation data that came in higher than anticipated. Hawkish remarks from several Federal Reserve officials have further reinforced the view that persistent price pressures necessitate a tighter monetary policy stance.
Throughout the year, inflationary pressures have been influenced by factors such as the conflict involving Iran, tariff policies, and a rapid surge in data center investments. These conditions prompted the Federal Reserve to resume its tightening cycle in September, following a three-year period without interest rate hikes.
The prospect of higher US interest rates has enhanced the appeal of dollar-denominated assets by offering greater yields. Market attention is now focused on just how aggressively the Federal Reserve will tighten policy, particularly if inflationary pressures persist in the coming months.
