The average interest rate on 30-year fixed-rate mortgages surged to 7.82 percent this week, the highest level in three weeks, in part responding to a signal by the Federal Reserve that it may raise short-term rates later this year.

The average was up from 7.70 percent last week, according to a weekly survey released Thursday by Freddie Mac.

Mortgages rates have been on an upward climb this year.

The average rates on a 30-year mortgage have hit a low of 6.74 percent in late January and a high of 8.15 percent in mid-August.

Fifteen-year mortgages, a popular option for refinancing, averaged 7.43 percent this week, also up from the average of 7.35 percent last week.

On one-year adjustable-rate mortgages, lenders were asking an average initial rate of 6.27 percent this week, up from 6.12 percent the previous week.
