but we are talking about STRIPS (separate trading of registered interest and principal securities), which splits out coupon payments and principal payment into separate securities.
“The US Treasury does not issue zero-coupon securities with maturities greater than a year, but it has a program whereby the coupon and principal payments of standard Treasury securities can be disaggregated and traded separately as zero-coupon securities. This is called the STRIPS program, which the Treasury launched in 1985. STRIPS stands for Separate Trading of Registered Interest and Principal of Securities.
Under the program, a financial institution can present the Treasury with a standard Treasury note, Treasury bond or TIPS to be “stripped.” The Treasury disaggregates the individual cash flows into separate securities, which are returned to the financial institution. For example, a newly issued 5-year note would be stripped into eleven separate securities—ten representing the note’s semiannual coupon payments, and one representing its final principal payment. The new securities are called coupon strips and principal strips. Collectively, they are called Treasury strips or just strips.”
