Case-Shiller CPI is formulated by substituting the Case-Shiller housing index for Owner's Equivalent Rent in the CPI. For a complete description of the reasons and methodology, please see What's the Real CPI?



The chart and commentary below is courtesy of my friend "TC" who writes:



CS-CPI continues to fall albeit at a less rapid pace and measures -5.1% YOY. Meanwhile the government’s CPI-U also continues to fall at a slower pace and measures -1.5% YOY. The divergence is to due to the government’s housing metric of Owners’ Equivalent Rent (OER) continuing to show price increases (+1.7% YOY) vs. Case-Shiller data showing price decreases (-13.3% YOY).

Since the Case Shiller housing market peak in June 2006, OER is up +7.7%, while the Case-Shiller index is down -30.9% - an amazing 3860 basis point divergence!



CS-CPI YOY has now fallen for 11 consecutive months and 14 of the past 18. Meanwhile the government's CPI-U YOY has fallen for 6 consecutive months.
