Pricing Bermudan Swaptions on the LIBOR Market Model using the Stochastic Grid Bundling Method. Stef Maree∗,. Jacques du Toit†. Abstract. We examine. Abstract. This paper presents a tree construction approach to pricing a Bermudan swaption with an efficient calibration method. The Bermudan swaption is an. The calibration adjusts the model parameters until the match satisfies a threshold of certain accuracy. This method, though, does not take into account the pricing.

The swaption prices are then used to compare the model’s predicted values. One useful approximation, initially developed by Rebonato, is the following, which computes the Black volatility for a European swaption, given an LMM with a set of volatility functions swwption a correlation matrix.

The hard-coded data for the zero curve is defined as: Zero Curve In this example, the ZeroRates for a zero curve is hard-coded. The Hull-White model is calibrated using the function swaptionbyhwwhich constructs a trinomial tree to price the swaptions. priicng
Based on your location, we recommend that you select: To compute the swaption prices using Black’s model:. For Bermudan swaptions, it is typical to calibrate to European swaptions that are co-terminal with the Bermudan swaption to be priced. The function swaptionbylg2f is used to germudan analytic values of the swaption price for model parameters, and consequently can be used to calibrate the model.

The choice with the LMM is how to model volatility and correlation and how to estimate the parameters of these models for volatility and correlation. In practice, you may use a combination of historical data for example, observed correlation between forward rates and current market data.

The hard-coded data for the zero curve is defined as:. Once the functional forms have been specified, these parameters need to be estimated using market data. However, other approaches for example, simulated annealing may be appropriate. The following matrix shows the Black implied volatility for swaptioh range of swaption priclng dates columns and underlying swap maturities rows. For this example, two relatively straightforward parameterizations are used.

In the case of swaptions, Black’s model is used to imply a volatility given the current observed market price. Specifically, the lognormal LMM specifies the following diffusion equation for each forward rate. All Examples Functions More.

Starting parameters and constraints for and are set in the variables x0lband ub ; these could also be varied depending upon the particular calibration approach.
In this case, all swaptions having an underlying tenor that matures before the maturity of the swaption to be priced are used in the calibration. Other MathWorks country sites are not optimized for visits from your location.
