Core-CPI has remained relatively steady and was actually 18 basis points higher month-over-month in January. The year-over-year core-CPI has remained between 1.50%-2% for the past two years. Unfortunately, the core-CPI series only goes back to 1958 so we can't see how low it got in the first two periods when the headline CPI went negative. In October 2009, however, core-CPI printed a year-over-year change 0.60%

The housing component of CPI looks like it should be the headline CPI in the near future. The vacancy rate is at its lowest level since 1995


Lastly, while headline CPI is at lowest level since 2009. Our CPI diffusion index is actually higher than it was in November. The diffusion index looks at the year-over-year change of each component. If it is higher than a year ago it registers +1, if it lower than a year ago it registers a 0.
