This is the class for the European-style swaption, an option to enter into a swap (payer or receiver of the fixed cpn), that starts in the future and with a fixed maturity, at a swap rate fixed today.

Methods

value

value(self, value_dt, discount_curve, model)
Valuation of a Ibor European-style swaption using a choice of models on a specified valuation date. Models include FinModelBlack, FinModelBlackShifted, SABR, SABRShifted, FinModelHW, FinModelBK and FinModelBDT. The last two involved a tree-based valuation.

cash_settled_value

cash_settled_value(self, value_dt: financepy.utils.date.Date, discount_curve, swap_rate: float, model)
Valuation of a Ibor European-style swaption using a cash settled approach which is a market convention that used Black's model and that discounts all of the future payments at a flat swap rate. Note that the Black volatility for this valuation should in general not equal the Black volatility for the standard arbitrage-free valuation.

print_swap_fixed_leg

print_swap_fixed_leg(self)
Print the present value of the fixed leg of the underlying swap.

print_swap_float_leg

print_swap_float_leg(self)
Print the present value of the floating leg of the underlying swap.
