From Freddie Mac today: Mortgage Rates Roiling From Taper Talk

Freddie Mac today released the results of its Primary Mortgage Market Survey® (PMMS®), showing average fixed mortgage rates jumping along with bond yields amid recent Fed remarks that it could begin tapering its bond purchases later this year. The average 30-year fixed-rate mortgage rose from 3.93 percent last week to 4.46 percent this week; the highest it has been since the week of July 28, 2011. ...

30-year fixed-rate mortgage (FRM) averaged 4.46 percent with an average 0.8 point for the week ending June 27, 2013, up from last week when it averaged 3.93 percent. Last year at this time, the 30-year FRM averaged 3.66 percent.

15-year FRM this week averaged 3.50 percent with an average 0.8 point, up from last week when it averaged 3.04 percent. A year ago at this time, the 15-year FRM averaged 2.94 percent.

Mortgage rates have increased for seven consecutive weeks, and spiked higher last week.

This graph shows the relationship between the monthly 10 year Treasury Yield and 30 year mortgage rates from the Freddie Mac survey.

Currently the 10 year Treasury yield is 2.48% and 30 year mortgage rates are at 4.46% (according to Freddie Mac). Based on the relationship from the graph, if the ten year yield stays in this range, 30 year mortgage rates might move down next week to 4.4% or so in the Freddie Mac survey.

Note: The yellow markers are for the last three years with the ten year yield below 3%. A trend line through the yellow markers only is a little lower, but still over 4.2% at the current 10 year Treasury yield.

The second graph shows the 30 year fixed rate mortgage interest rate from the Freddie Mac Primary Mortgage Market Survey® compared to the MBA refinance index.

The refinance index has dropped sharply recently (down almost 42% over the last 7 weeks) and will probably decline significantly if rates stay at this level.
