We construct multi-currency models with stochastic volatility and correlated stochastic interest rates with a full matrix of correlations. We first deal with a foreign exchange (FX) model of Heston-type, in which the domestic and foreign interest rates are generated by the short-rate process of...

Capturing the … correlation structure in the two-factor Hull-White model is an integral element of CVA (XVA) modeling. However, the correlation …, the correlation structure of the two-factor Hull-White model is analyzed in detail. The correlation structure of co …

We propose a new derivation of the Heath–Jarrow–Morton risk-neutral drift restriction that takes into account nonzero instantaneous correlations between factors. The result allows avoiding the orthogonalization of factors and provides an approach by which interest rate derivatives can be...
