In this paper we focus on a fundamental practical issue regarding the bilateral counterparty risk adjustment. The past literature assumes that, at the moment of the first default, a risk-free closeout amount will be used. The closeout amount is the net present value of the residual deal which is...

Gaussian Copula as a model for default correlation has been recently criticized for a number of fallacies in its application to pricing and risk management of financial liabilities. Here we point out an element of model risk that appears to be overlooked. When the Gaussian Copula is applied to...

Different anomalies have appeared in the interest rate market after the burst of the credit crunch. A wide wedge has opened between the market quotes of Forward Rate Agreements and their standard spot Libor replication, and large Basis Spreads have appeared for exchanging floating payments with...

This work focuses on the swaptions automatic cascade calibration algorithm (CCA) for the LIBOR Market Model (LMM) first appeared in Brigo and Mercurio (2001). This method induces a direct analytical correspondence between market swaption volatilities and LMM parameters, and allows for a perfect...

The Initial Margin is an amount of collateral that CCPs and Regulators require dealers to post beside Variation Margin. Computing the funding cost associated to Initial Margin requirements, at times called MVA (Margin Value Adjustment), presents both conceptual and computational challenges. Here...

This paper presents the implementation of a derivative market on a public blockchain. Managing derivatives on a distributed system requires a careful re-design of the derivatives business model. The implementation presented here provides many of the features financial professionals are used to,...

We show that when a derivative portfolio has different correlated underlyings, hedging using classical greeks (first-order derivatives) is not the best possible choice. We first show how to adjust greeks to take correlation into account and reduce P&L volatility. Then we embed...
