Excerpt:
Both the Case-Shiller House Price Index (HPI) and the Federal Housing Finance Agency (FHFA) HPI for September were released today. Here is a graph of the month-over-month (MoM) change in the Case-Shiller National Index Seasonally Adjusted (SA).
The Case-Shiller Home Price Indices for “September” is a 3-month average of July, August and September closing prices. July closing prices include some contracts signed in May, so there is a significant lag to this data.
The MoM decrease in Case-Shiller was at -0.76% seasonally adjusted. This was the third consecutive MoM decrease, and slightly less than the decrease last month. This suggests prices fell sharply for September closings.
On a seasonally adjusted basis, prices declined in all of the Case-Shiller cities on a month-to-month basis. The largest monthly declines seasonally adjusted were in San Francisco (-2.2%), Phoenix (-2.1%) and Las Vegas (-2.1%). San Francisco has fallen 10.3% from the peak in May 2022.

The September Case-Shiller report is mostly for contracts signed in the May through August period when 30-year mortgage rates were in the low-to-mid 5% range. The October report will mostly be for contracts signed in the June through September period – when rates were mostly in the low-to-mid 5% range (except September).The impact from higher rates in September and October will not show up significantly for a few more months.
