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.

To compute the swaption prices using Black’s model:. Click here to see To view all translated materials including this page, select Country from the country navigator on the bottom of this page. Click the button below to return to the English version of the page. The Hull-White one-factor model describes the evolution of the short rate and is specified by the following:.
Trial Software Product Updates. For Bermudan swaptions, it is typical to calibrate to European swaptions that are co-terminal with the Bermudan swaption to be priced. Other MathWorks country sites are not optimized for visits from your location. The swaption prices are then used to compare the model’s predicted values.
In practice, you may use a combination of historical data for example, observed correlation between forward rates and current market data. For this example, only swaption data is used.

Selecting the instruments to calibrate the model to is one of the tasks in calibration. Translated by Mouseover text to see original.
Calibration consists of minimizing the difference between the observed market prices and the model’s predicted prices. Calibration consists of minimizing the difference between the observed implied swaption Black volatilities and the predicted Black volatilities.
In this case, all swaptions having an underlying tenor that matures before the maturity of the swaption to be priced priclng used in the calibration. Monte Carlo Methods in Financial Engineering. The following matrix shows the Black implied volatility for a range of swaption exercise dates columns and underlying swap maturities rows.
Norm of First-order Iteration Func-count f x step optimality 0 3 0. Swaption prices are computed using Black’s Model.

Options, Futures, swaaption Other Derivatives. Further, many different parameterizations of the volatility and correlation exist. For this example, two relatively straightforward parameterizations are used. Calibration consists of minimizing the difference between the observed market prices computed above using the Black’s implied swaption volatility matrix and the model’s predicted prices.
Once the functional forms have been specified, these parameters need to be estimated using market data. The hard-coded data for the zero curve is defined as: The hard-coded data for the zero curve is defined as:.
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. The Hull-White model is calibrated using the function swaptionbyhwwhich constructs a trinomial tree to price the swaptions.

Black’s model is often used to price and quote European brmudan interest-rate options, that is, caps, floors and swaptions. Select the China site in Chinese or English for best site performance. In this example, the ZeroRates for a zero curve is hard-coded.
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 and a correlation matrix.
