**Hot September CPI data released mid-week drove the primary move in DXY during the week of October 12, 2026.** Headline inflation accelerated to 3.7% year-over-year from 3.4%, exceeding the 3.6% consensus, while core CPI rose to 2.6% from 2.4%. The hotter-than-expected print pushed market-implied odds of a Federal Reserve rate hike at the October 27-28 FOMC meeting from roughly 22% to around 42-45%, lifting two-year Treasury yields and supporting the dollar. DXY traded near 102.1-102.6 early in the week, surged above 102.9 to an 18-month high on the inflation reaction, then eased toward 102.1 by October 15 amid some profit-taking and mixed Fed commentary. Trader positioning reflected the repricing of the policy path, with higher yields widening interest-rate differentials versus other major central banks and reinforcing safe-haven demand amid geopolitical and energy-price volatility.
