FYI,
Think Credit Union has an August certificate savings account special of 1.86% APY. That rate is guaranteed for two years. Minimum opening amount is $2500, and minimum withdrawal is $2500. After seven days, there are no withdrawal penalties.
Highest rate I could find on
BankRate.com is 1.42% APY on a conventional one month (30 day) CD, with no interest rate lock on that. (Meaning, if interest rates go down, you have to roll over into something with a lower rate.) And that's a bank in Puerto Rico. You have to go to a conventional 6 month CD to get a higher rate but, again, no protection against lower interest rates 6 months from now, and you can't touch your money for 6 months.
Only bad news is there are some requirements to join this credit union -- it's not open to everyone. Check to see if you qualify. As a general comment, credit unions are absolutely wonderful institutions for DUers, since they tend to keep fees low and returns high.
