This book provides a straightforward, rigorous, and thorough introduction to foreign exchange. Blending theory and practice, "Foreign Exchange" progresses from a short history of the foreign exchange market and a description of the FX Spot Market through currency forwards and other derivatives, to FX options strategies and more exotic and complex structures making this technical information generally accessible. What is even more unique is that this book frames the foreign exchange market in practical economic terms, so that it can be used as a primer or as a practical guide for traders, institutional investors, and the banking community to make sense of today's wide variety of FX products in an ever-evolving and dynamic market environment.
