Mortgage buyer Freddie Mac said Thursday that the average rate for 30-year fixed loans fell to 3.43% from 3.54% last week. That's near the 3.31% reached in November, which was the lowest on records dating to 1971.
The average rate on 15-year fixed mortgages dipped to 2.65% from 2.74% last week. That's slightly above the record low of 2.63%, also reached in November.
Low mortgage rates are helping sustain a housing recovery that began last year. Home sales and residential construction are up, prices are rising and more Americans are refinancing. That's helped the broader economy.
Mortgage rates have been low because they tend to track the yield on 10-year Treasury notes. The yield has fallen in recent weeks and went as low as 1.71% April 5, after a weak report on March hiring drove investors to seek the safety of a U.S. Treasury bonds. When demand rises, bond yields fall.
On Thursday, the yield was up to 1.79%, still low by historical standards.
