The U.S. Department of the Treasury issues debt securities called Treasury bonds (aka Treasuries) that provide fixed income in the form of bond interest rate payouts over time.

Ways to buy treasury bonds
There are several options to purchase treasury bonds. Let us understand them in more detail.

You can buy treasury bonds directly at TreasuryDirect.gov., The U.S. Treasury’s online platform. They allow individuals to buy treasury bonds at auction, directly from the source. You need to create a TreasuryDirect account and take part in non-competitive bids.

If you prefer not to buy individual bonds, you can invest in treasury bond mutual funds or ETFs (exchange-traded funds). Treasury bond mutual funds pool money from many investors to buy a diversified portfolio of U.S. Treasury securities. These funds are typically actively managed, meaning a fund manager decides which bonds to buy and sell based on the fund’s objectives.
Treasury bond ETFs are similar, but they trade on stock exchanges like individual stocks.
