There may be some correlation between CD interest rates and inflation. For example, in one situation interest rates might be 15% and inflation 15%, and in another situation interest rates might be 2% and inflation may be 2%. These factors cancel out, so the
real interest rate is zero in both of these examples. However the real rates of return offered by CDs, as with other fixed interest instruments, can vary significantly. For example, during a
credit crunch banks are in dire need of funds, and CD interest rate increases may not track inflation. The above does not include
taxes. When taxes are considered, the higher-rate situation above is worse, with a lower (more negative) real return, although the before-tax real rates of return are identical. The after-inflation, after-tax return is what is important. Author
Ric Edelman writes: "You don't make any money in bank accounts (in real economic terms), simply because you're not supposed to." On the other hand, he says, bank accounts and CDs are fine for holding cash for a short amount of time. CD rates are correlated with the expected inflation at the time the CD is bought. The actual inflation may be lower or higher. Locking in the interest rate for a long term may be bad (if inflation goes up) or good (if inflation goes down). For example, in the 1970s, inflation increased higher than it had been, and this was not fully reflected in interest rates. This is particularly important, for longer-term notes, where the interest rate is locked in for some time. A little later, the opposite happened, and inflation declined. In general, and similar to other fixed-interest investments, the economic value of a CD rises when market interest rates fall, and vice versa. Some banks pay lower than average rates, while others pay higher rates. In the United States, depositors can take advantage of the best FDIC-insured rates without increasing their risk. As with other types of investment, investors should be suspicious of a CD offering an unusually high rate of return.
