I’ve got both a 5% savings and a 5.6% CD (13 months). Both are absolutely safe. Aren’t bonds a good bet these days, too?
It depends on which direction you think interest rates are going to go. If you think they will go down then you may want to buy the 3 year CD and lock in that interest rate for 3 years. If you think they will go up or stay the same you would want the 1 year CD.
