NEW YORK (CNN/Money) - Interest rates for savings products were largely flat the week ended Aug. 17, with 12-month CDs creeping to a 1.64 percent average from 1.63 percent the previous week.

"There has actually been very small to no movement in the CD rates over the last week." said Randy Rosen, manager of deposit research at Informa Research Services, Inc. "Any 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."

"It appears that even though the Federal Reserve made a rate change over a week ago, the financial institutions have not reacted to that change with much movement in the checking or money market products," he added.

Rates for 12-month CDs ranged from 0.35 percent on the low end to 3.05 percent for the week, according to Informa Research Services. A month earlier, the average rate stood at 1.57 percent.

Meanwhile, interest rates for money market and checking accounts showed no signs of life.
