Reinvestment risk
Reinvestment risk is a form of financial risk. It is primarily associated with fixed income securities (including bonds), in the form of early redemption risk and coupon reinvestment risk. Early redemption One form of reinvestment risk is the possibility that the cash flows from an investment might somehow be cancelled or stopped before its stated maturity date. This could happen if the issuer has the right to redeem (or "call") a fixed income security before its contractual maturity date. In that case, the investor might not be able to find a new investment which is as attractive as the security being redeemed. Mortgage loans typically include a prepayment option, which permits the borrower to repay a portion or all of the loan before scheduled maturity. This creates reinvestment risk for lenders and mortgage-backed securities holders. Early termination of the loan can also occur when the borrower sells the property, refinances the loan or defaults. In each case, the lender and the holder of a mortgage-backed security cannot be certain of receiving the expected cash flows from the loan. Prepayment models have been developed to help deal with this risk. Coupon reinvestment Investors who plan to reinvest periodic interest (or "coupon")
