WASHINGTON -- Mortgage interest rates rose for a 10th straight week and remained at their highest since September 2003.

Freddie Mac said Thursday that the average for 30-year, fixed-rate mortgages stood at 6.37percent.

That was compared to 6.36 percent last week.

A year ago, the 30-year stood at 5.74 percent.

A competing survey from Bankrate.com had the average 30-year fixed-rate mortgage remaining at 6.42 percent.

The average for 15-year fixed mortgages was at 5.90 percent, also up slightly.

For one-year adjustable-rate mortgages, the average was put at 5.20 percent.

That was compared to 5.12 percent last week.

The average for the one-year ARM stood at 4.17 percent a year ago.

Inflation concerns have pushed mortgage rates higher over the past two months, but those concerns eased somewhat this week, according to Bankrate.com.

The release of both the Producer Price Index and Consumer Price Index calmed fears that inflation might be getting out of hand.
