Derivative Pricing and Credit Exposures Modelling: Python Prototype of XVA for Practitioners (2.0)

-------------------------SECOND EDITION ------------------- ABOUT THE BOOK It is a practical guide to introduce Derivative pricing models and Counterparty Credit Exposure modelling. XVA has been a hot topic in the industry for the last decade and probably more years to come. It has gathered many powerful brains into these subjects within Quantitative Finance. This book opens up the subject for non-mathematical savvy people. Many simple examples are used to explain concepts like Randomness of asset behavior, Derivatives , Counterparty Credit Risk, Monte Carlo method and most importantly, XVAs. With the help of graphs and Python prototypes, the technical complexity will be lower and the subject much easier to understand.

Desk level risk management including hedging and client facing tactics are also included in this edition. I covered this during my time at JP Morgan and Barclays Credit Hybrids derivatives Trading & Structuring around 2008-2012. Markets have changed a lot since the financial crisis and most of these products now have a very thin market with a small number of active players. This is the reason why I only touched lightly on products like FTD/NTD and Recovery Swaps, but I wanted to preserve the product knowledge and hope that my readers will enjoy it. Many thanks to Dr. Günter Umlauf for his proof reading and inspiring discussions which have helped me to retrieve those old golden memories.
