We try and apply the single-scenario version of the general model in Castagna, Mercurio and Mosconi (2010) to the pricing of CDOs. We are able to establish a unified approach to both evaluate the Credit VaR and the risk of structured products, and thus evaluate on a consistent and uniform basis...

Recent empirical studies on interest rate derivatives have shown that the volatil- ity structure of interest rates is frequently humped. Mercurio and Moraleda (1996) and Moraleda and Vorst (1996a) have modelled interest rate dynamics in such a way that humped volatility structures are possible...

In this paper, we define and model forward risk-free term rates, which appear in the payoff definition of derivatives, and possibly cash instruments, based on the new interest-rate benchmarks that will be replacing IBORs globally. We show that the classical interest rate modeling framework can...

In this article, we propose a simple interest rate model, which can well accommodate swaption smiles, while recovering market prices of CMS swap spreads. The model is based on a (possibly multi-factor) Gaussian short rate model coupled with parameter uncertainty. Examples of calibration to real...

We introduce a simple extension of a shifted geometric Brownian motion for modelling forward LIBOR rates under their canonical measures. The extension is based on a parameter uncertainty modelled through a random variable whose value is drawn at an infinitesimal time after zero. The shift in the...
