The hotter-than-expected inflation data immediately altered expectations for monetary policy. Ahead of the report, Federal Reserve Governor Christopher Waller said in a speech in London that a strong policy move might be necessary if the underlying inflation measure reached 0.3 percent.
If the October CPI inflation data out later today are similar to the past two monthly readings, with core CPI inflation around 0.3 percent or even higher, then a stronger policy move may be needed,
