Step Up Bond

Step Up Bond

Definition: A bond with a coupon that increases over time on schedule – unless the issuers call it. Ordinarily, the coupon begins slightly above the going rate for short-term bonds and the bond is callable at par on each coupon reset date.

Example: FHLBB issued in December 1997 a bond that matures in 1/03. Its first coupon is 6%, and the coupon increases to 6 3/8 % in 1/99, 6.5% in 1/00, 7% in 1/01, then 8% in 1/02 through maturity.

Application: At the start of each coupon accrual period, the investor bets that the next oversize coupon compensates for the possibility that the issuer may call the bond.

Pricing: At the last reset date, the issuer has an option to call the bond. At each previous reset date, the issuer can either call the bond or pay a forward premium (the excess of the next coupon(s) over the going market coupon) for the current installment of a compound option. Thus, the Step Up Bond has a sort of embedded Chooser Option (q.v.).

Risk Management: The Step Up Bond embodies two kinds of market risk (interest rate risk and exposure to the volatility of the rates), and may embody credit risk.
