NEW YORK (CNN/Money) - Interest rates for savings products were little changed the week ended Aug. 24, with 12-month CDs creeping to a 1.65 percent average from 1.64 percent the previous week.

"The movement in the CD rates (especially in the CDs for 12 months or longer) would be primarily due to the fluctuations in the T-Bill rate," said Randy Rosen, manager of deposit research at Informa Research Services, Inc.

"Banks have been a little slow to change the rates on some of the liquid products such as money market accounts."

Rates for 12-month CDs ranged from 0.35 percent on the low end to 3.04 percent, according to Informa Research Services. A month earlier, the average rate stood at 1.59 percent.
