💹 Market Reaction
The cooler inflation tone prompted renewed rate-cut expectations:
-
U.S. Treasury yields edged lower.
-
The U.S. dollar weakened broadly, especially against the euro, yen, and commodity currencies.
-
Risk assets such as equities and gold firmed slightly as investors priced in a softer policy stance from the Federal Reserve going into the next FOMC meeting.
In short, the September CPI confirmed a controlled inflation slowdown, reigniting expectations for a gradual rate-cut cycle and temporarily shifting sentiment toward dollar weakness.
