What to consider before buying treasury bonds

If you’re looking to buy Treasury securities, know that Treasury bonds are a different category than savings bonds. Unlike savings bonds, Treasury bonds can be traded before the maturity date on secondary markets. This makes Treasury bonds a liquid investment that you can easily convert to cash. (Other liquid Treasury securities include short-term Treasury bills, which can mature in a matter of weeks.)

Treasury bonds are considered low risk because the federal government guarantees interest. The same cannot be said for equities like stocks, ETFs, and mutual funds that experience volatility.

However, the benefit for your money is also low, because interest payments tend to be on the low side. Other types of bonds, like Series I savings bonds that reflect inflation trends, may offer higher yields if inflation becomes greater than market consensus.

If you want to buy bonds, know that the Internal Revenue Service (IRS) requires you to pay federal income tax each year on any interest you earn. On the plus side, there are no state or local tax requirements.
