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 as well as the volume of 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 is showing that the average rate for a 30 year fixed rate mortgage (from FHA and conforming GSE data) jumped a notable 16 basis points to 3.91% since last week while the purchase application volume declined 2% and the refinance application volume declined 15% over the same period.
Rates have risen steadily for the past few weeks seemingly correlated with the Feds recent suggestion that they may start to wind down GSE purchases later this year. Only time will tell if this is a trend or simply an aberration.
