Long-term mortgage rates increased slightly as the U.S. economy showed signs that the worst of the coronavirus-fueled recession may have passed.

The average interest charged on a 30-year mortgage was 3.18% this week, up from 3.15% a week ago, according to a report Thursday by mortgage buyer Freddie Mac. That average is down from 3.82% a year ago.

The economic collapse following the COVID-19 outbreak has corresponded with a decline in mortgage rates. But there are signs that the economy may have already bottomed as government data shows that applications for jobless aid — though still historically high — are steadily falling.
