Editing Zero-coupon bond (section)

==Strip bonds==
Zero coupon bonds have a duration equal to the bond's time to maturity, which makes them sensitive to any changes in the interest rates. Investment banks or ''dealers'' may separate coupons from the principal of coupon bonds, which is known as the residue, so that different investors may receive the principal and each of the coupon payments.  That creates a supply of new zero coupon bonds.

The coupons and residue are sold separately to investors.  Each of the investments then pays a single lump sum. That method of creating zero coupon bonds is known as ''stripping'', and the contracts are known as strip bonds. "STRIPS" stands for '''S'''eparate '''T'''rading of '''R'''egistered '''I'''nterest and '''P'''rincipal '''S'''ecurities.<ref>{{cite web

Dealers normally purchase a block of high-quality and [[callable bond|non-callable bonds]], often government issues, to create strip bonds. A strip bond has no [[reinvestment risk]] because the payment to the investor occurs only at maturity.

The impact of interest rate fluctuations on strip bonds, known as the [[bond duration]], is higher than for a coupon bond. A zero coupon bond always has a duration equal to its maturity, and a coupon bond always has a lower duration.  Strip bonds are normally available from investment dealers maturing at terms up to 30 years. For some [[Canada|Canadian]] bonds, the maturity may be over 90 years.{{citation needed|date=March 2013}}

In Canada, investors may purchase packages of strip bonds, so that the cash flows are tailored to meet their needs in a single security.  These packages may consist of a combination of interest (coupon) and/or principal strips.

In [[New Zealand]], bonds are stripped first into two pieces—the coupons and the principal.  The coupons may be traded as a unit or further subdivided into the individual payment dates.

In most countries, strip bonds are primarily administered by a [[central bank]] or [[central securities depository]].  An alternative form is to use a [[custodian bank]] or trust company to hold the underlying security and a transfer agent/registrar to track ownership in the strip bonds and to administer the program.  Physically created strip bonds (where the coupons are physically clipped and then traded separately) were created in the early days of stripping in Canada and the [[United States|U.S.]], but have virtually disappeared due to the high costs and risks associated with them.
