The Mortgage Bankers Association (MBA) publishes the results of a weekly applications survey that covers roughly 50 percent of all residential mortgage originations and tracks the average interest rate for 30 year and 15 year fixed rate mortgages, 1 year ARMs as well as application volume for both purchase and refinance applications.
The purchase application index has been highlighted as a particularly important data series as it very broadly captures the demand side of residential real estate for both new and existing home purchases.
The latest data indicates that the average rate for a 30 year fixed rate mortgage decreased 9 basis points since last week to 5.19% while the purchase application volume declined 9.76% while the refinance application volume decreased a whopping 30.30% compared to last week’s results.
In past weeks I have speculated that the MBA has some difficulty seasonally adjusting their weekly series during the months of November to February and with the latest release I’m feeling more certain of this.
For example, although it’s obvious that when rates decline refinancing and purchase activity increases, the last two months of release would have you believe that purchase activity during the weeks just preceding and just after Christmas met or even exceeded the activity seen throughout the height of the summer selling season… an unlikely result that MUST carry with it some element of distortion.
It’s important to note that the purchase application volume now sits at the lowest point in at least two years even as rates remain exceptionally low.
In the coming weeks I hope to provide more evidence that demonstrates that these indices are slightly broken.
