How does the yield of a long-term bond compare to the yield of a short-term bond?

Short-term bonds are attractive to many investors because they don't require you to tie up your money for long periods of time. They're suitable for those who will need to spend their invested money in the near future, but they can also be useful even for long-term investors. For instance, if you expect a rise in interest rates over the short run, then investing in a short-term bond will let you reinvest the money at maturity in a bond that by then should be paying a much higher interest rate.

The downside of short-term bonds is that they generally pay lower interest rates than long-term bonds. As a result, in order to get the benefits of a short-term bond, you typically earn less income, forcing you to make sure that the advantages short-term bond investing brings are truly worth it for you.

Long-term bonds have much different attributes from short-term bonds. With a long-term bond, you'll typically earn a higher interest rate, as the entities that issue the bonds will be willing to pay more in interest in exchange for the security of locking in a known rate for a longer period of time. If you need to maximize income, then a long-term bond can look extremely attractive.

The downside of long-term bonds is that you lack the flexibility that a short-term bond offers. If interest rates rise, for instance, the value of a long-term bond will usually go down, penalizing you for having committed to a locked-in rate for the long haul. In addition, depending on the issuer, a long-term bond can have a greater risk of default -- especially if the same issuer has other outstanding bonds that mature before the bonds you own.
