The Consumer Price Index (CPI) is the one thing we wait for after the jobs report comes out.  After CPI, the one thing becomes the next jobs report (and so on and so on...).  The jobs report came out last week.  CPI comes out next Tuesday.  So what's up with CPI being in the news today?  Like many economic reports, CPI is seasonally adjusted.  If it weren't, it would be much harder to interpret without running one's own seasonal adjustments.  But seasonal patterns can change over time for so many reasons.  The adjustments stay more relevant if they're periodically updated.  That update was published today and applied to PAST releases of CPI.  Next week's release will be the most current release and a far more important event than today's revisions (which ended up being a non-event).
