BankShout surveys the top jumbo certificate of deposit yields, current as of Friday, May 21, 2010. Annual percentage yields (APY) are for U.S. national and Internet banks. Jumbo CDs traditionally refer to deposit amounts of at least $100,000. Banks in our survey are insured by the Federal Deposit Insurance Corporation.

Banks largely kept jumbo CD rates the same from two weeks earlier, according to our latest BankShout survey of U.S. national and Internet-chartered banks. The jumbo yield leader remains EverBank. The Jacksonville, Florida-based bank has a 3.14% APY on its Yield Pledge CD; the term is for 5 years.

Nationwide once again held its 5-year jumbo APY at 3.10%, good for second place. USAA remained in third, at 3.05% APY, although it should be noted that USAA compounds interest on a monthly, as opposed to a daily basis. In joining the trend of keeping yields static, State Farm Bank is still offering 3.02% APY for a 5-year jumbo term.

A trio of financial institutions held steady at 3.00% for a five year jumbo, including Discover Bank, Third Federal Savings and Loan, and troubled, headline-making AIG Bank.

By contrast, 3-year jumbo yields become slightly less competitive this week, with two of the top three banks cutting rates for that term. USAA remains on top, holding its 3-year APY at 2.40%. But Aurora Bank, FSB, and Ally Bank land at 2.38% APY and 2.31% APY, respectively, for 3-year jumbos; both of those banks were at 2.39% two weeks ago.
