Resumo
In this paper we examine the term structure of instantaneous volatilities of forward rates for the Spanish market covering the period 1999-2002. This analysis is undertaken within the LIBOR Market Model framework. A new model with easily understandable parameters is proposed to describe the behaviour of the instantaneous volatility of forward rates. Two other alternatives are calibrated using data from the cap market and used as benchmarks to test the accuracy of the new model.
