Interest Rate Models’ Implied Volatility Function Stochastic Movements
نویسنده
چکیده
Abstract: This paper presents a one factor and a two factor arbitrage-free interest rate models with parsimonious implied volatility functions. The models are empirically tested on the entire swaption surface in three currencies (U. S. dollar, Euro and Japanese yen) over a five year period. They are shown to be robust in explaining the swaption values, and the implied volatility functions are shown to exhibit a three factor movement in all three currencies.

VAR Modeling for Dynamic Loadings Driving
The implied volatility of an option as a function of strike price and time to maturity forms a volatility surface. Traders price according to the dynamics of this high dimensional surface. Recent developments that employ semiparametric models approximate the implied volatility surface (IVS) in a finite dimensional function space, allowing for a low dimensional factor representation of these dyn...
متن کاملLinearity-Generating Processes, Unspanned Stochastic Volatility, and Interest-Rate Option Pricing
We propose to use the linearity-generating framework to accommodate the evidence of unspanned stochastic volatility: Variations in implied volatilities on interest-rate options such as caps and swaptions are independent of the variations on the interest rate term structure. Under this framework, bond valuation depends only on the transition dynamics of interest-rate factors, but not on their vo...
متن کاملOption-based tests of interest rate diffusion functions
The consistent finding in papers that estimate the interest rate diffusion function is that interest rate volatility is an increasing function of the spot rate. This paper introduces and implements regression tests of monotonic diffusion functions using an implied volatility proxy for objective volatility. Using the case of three-month LIBOR rates, this paper documents that the relationship bet...
متن کاملExtended Libor Market Models with Affine and Quadratic Volatility
The market model of interest rates specifies simple forward or Libor rates as log-normally distributed, their stochastic dynamics has a linear volatility function. In this paper, the model is extended to quadratic volatility functions which are the product of a quadratic polynomial and a level-independent covariance matrix. The extended Libor market models allow for closed form cap pricing form...
متن کاملOption Prices with Uncertain Fundamentals Theory and Evidence on the Dynamics of Implied Volatilities
In an incomplete information model, investors' uncertainty about the underlying drift rate of a rm's fundamentals a ects option prices through (i) endogenous and belief-dependent stochastic volatility, (ii) stochastic covariance between returns and volatility, and (iii) a market price of \belief risk." For the special case where the drift takes only two values, we provide an option pricing form...
