Mortgage rates retreated for the second week in a row, according to the latest data released Thursday by Freddie Mac.

Concern over the global economy is fueling volatility in the financial markets and pushing down rates on home loans. The 10-year Treasury yield closed at a two-month low on Wednesday. The movement of the 10-year Treasury bond is one of the best indicators whether mortgage rates will rise or fall. When yields go down, interest rates tend to go down.


The 30-year fixed-rate average dropped to 3.92 percent with an average 0.6 point, its lowest level since early November. (Points are fees paid to a lender equal to 1 percent of the loan amount.) It was 3.97 percent a week ago and 3.66 percent a year ago.
