Market Summary:

The US Dollar extended its gains sharply after the Federal Reserve raised interest rates by 25 basis points to 3.75%–4.00%, marking its first increase in more than three years.

Although the rate hike itself had already been largely priced into markets, the Fed delivered a more hawkish outlook than many investors expected. Sixteen of 18 policymakers projected at least one additional rate increase before the end of 2026, suggesting that the latest move may not be a one-off adjustment.

Fed Chair Kevin Warsh also reaffirmed the central bank’s commitment to controlling inflation, highlighting that price pressures remain too broad and persistent. Recent stronger-than-expected US inflation data, resilient economic activity and elevated energy prices have strengthened concerns that inflation may remain above the Fed’s target for longer.

The combination of a rate hike and expectations for further tightening provided strong support for the dollar. The Dollar Index rose around 0.6% following the decision, while shorter-dated Treasury yields climbed as traders repriced the future path of US interest rates.

Higher interest rates generally increase the relative attractiveness of dollar-denominated assets, particularly when other major central banks are expected to maintain a less aggressive policy stance.

Looking ahead, the dollar’s next direction will depend heavily on whether upcoming economic data continue to justify additional Fed tightening. Persistent inflation and resilient growth could reinforce expectations for another rate hike and extend the dollar’s bullish momentum. However, any signs of cooling inflation or weaker economic activity could reduce expectations for further tightening and trigger some profit-taking in the greenback.
