The US dollar retreated from an 18-month high on Thursday despite hotter than expected September inflation data.[^1]

September inflation was reported at 3.7%, exceeding the 3.6% expected by analysts. The reading initially strengthened the dollar and increased risk aversion.[^2][^3]

That initial reaction reversed, and markets normalized after the data release.[^4]
