A swaption is an option to enter an interest-rate swap at a fixed rate KK on a future date. A payer swaption gives the right to pay fixed; a receiver swaption the right to receive fixed. At expiry TT a payer is worth NA(T)max⁡(ST−K,0)N A(T)\max(S_T - K, 0), where STS_T is the par rate of the underlying swap then and A(T)A(T) its annuity. A callable bond is a bond its issuer may repay early, at a set price on set dates.

A 1y×10y payer and receiver swaption struck at a 4% forward, per 100 of notional, on a flat 4% curve. At expiry each pays the annuity (7.80) times the distance of the swap rate beyond the strike; a year before, the payer is worth its time value on top, at a normal volatility of 95 basis points. Illustrative; data: the chapter’s tutorial.
