CNBC analysis indicates that despite traders widely betting on the Federal Reserve pausing interest rate hikes at its October 28 meeting, new Chairman Kevin Warsh's refusal to follow traditional communication methods and his persistent concerns about inflation leave the rate hike decision uncertain. Warsh has repeatedly emphasized that the 2% PCE inflation target is "firm and fixed," and recent Consumer Price Index (CPI) and Producer Price Index (PPI) data both show persistent inflationary pressures, which could prompt him to push the Federal Open Market Committee (FOMC) for a surprise rate hike.
