Coupon stripping separates a bond's interest payments and principal repayment into separately tradable zero-coupon securities.
Coupon stripping is a financial mechanism that involves detaching the interest payments (coupons) from a bearer bond and selling them separately. This process converts the original bond into a zero-coupon bond. The decoupling of the coupon payments and the principal allows investors to manage their cash flows more flexibly and tailor their investment strategies according to their needs.
Coupon stripping allows the bondholder to sell the future interest payments (coupons) and the principal separately. For example, a 10-year bond with annual coupon payments can be split into 10 coupon payments and one principal repayment, creating 11 separate securities.
