Treasury Securities

Treasury securities are government bonds issued by the United States Department of the Treasury through the Bureau of the Public Debt. They are the debt financing instruments of the U.S. Federal government, and are often referred to simply as Treasuries. There are four types of treasury securities: Treasury bills, Treasury notes, Treasury bonds, and Savings bonds. All of the Treasury securities (besides savings bonds) are very liquid and are heavily traded on the secondary market.

Treasury Bond

Treasury bonds (or T-Bonds) mature in ten years or longer. They have coupon payment every six months like T-Notes, and are commonly issued with maturity dates of ten and thirty years. The secondary market is highly liquid, so the yield on the most recent T-Bond offering was commonly used as a proxy for long-term interest rates in general. This role has largely been taken over by the 10-year note, as the size and frequency of long-term bond issues declined significantly in the 1990s and early 2000s.
The U.S. Federal government stopped issuing the well-known 30-year Treasury bonds (often called long-bonds) on October 31, 2001. As the U.S. government used its budget surpluses to pay down the Federal debt in the late 1990s, the 10-year Treasury note began to replace the 30-year Treasury bond as the general, most-followed metric of the U.S. bond market. However, due to demand from pension funds and large, long-term institutional investors, along with a need to diversify the Treasury's liabilities - and also because the flatter yield curve meant that the opportunity cost of selling long-dated debt had dropped - the 30-year Treasury bond was re-introduced in February 2006.
