The US dollar index has broken through key technical resistance, extending a rally that has pushed the greenback to its highest level against a basket of major currencies since May 2025.
The move marks the dollar's sharpest monthly gain in nearly a year, driven by a rapid repricing of Federal Reserve policy expectations.
Traders are increasingly betting that a resilient US economy will force the Fed to maintain higher interest rates for longer, or potentially hike again.
This shift in sentiment has propped up short-term interest rates, widening the yield differential between the US and other major economies and providing a fundamental tailwind for the currency.
The rally is not merely technical; it reflects a growing consensus that US growth remains robust enough to sustain a hawkish monetary stance.
This development follows a period of significant volatility in currency markets.
