WHAT IS 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 and is now issued quarterly. This will bring the U.S. in line with Japan and European governments issuing longer-dated maturities amid growing global demand from pension funds. Some countries, including France and the United Kingdom, have begun offering a 50-year bond, known as a Methuselah.
