The dollar climbed sharply this week, positioning itself for its strongest performance since March. The advance follows fresh US inflation data that rekindled market expectations for Federal Reserve interest rate hikes through next year. Traders are recalibrating their forecasts as price pressures prove stickier than anticipated.

This shift in rate-hike probability has fueled a broad-based dollar strength. The dollar index surged, reflecting gains against major peers like the euro and yen. Currency markets are highly sensitive to any signal that the Fed will maintain higher rates for longer, which enhances the dollar's yield appeal.

Investors are now pricing in a more hawkish Fed stance, pulling forward expectations for the first hike. The data effectively ended the recent narrative of imminent rate cuts, triggering a reassessment of portfolio allocations. The dollar's trajectory underscores how quickly sentiment can turn on inflation prints.
