At this very moment, savings bonds accrue a very low interest rate. BUT, if it’s between CD’s and a bond, get the bond. With bonds, rates are variable and change every 6 months. They pay more than CD’s (any CD’s) and the interest is state tax free. So no matter what the rate is, it’s more cause you don’t pay tact on the interest. You do on the CD’s. And unlike stocks, the rate is guarantied not to go negative. And as long as you hold for no less than 5 years, there is no penalty if you cash in before the 30 years you get compounded interest on it. Don’t rule these out if you typically hold CD’s.
