The Big Idea
Value at Risk is the risk measurement tool that global banks, hedge funds, and regulators rely on to answer one question: how bad could things get tomorrow? Philippe Jorion’s framework distills that uncertainty into a single number — the maximum probable loss over a given time period at a given confidence level. That number is powerful, widely used, and genuinely useful. It is also completely silent on what happens when markets stop behaving normally — which is precisely when it matters most. This is the book that built modern risk management and, if read honestly, also explains why it keeps failing.

About the Author
Philippe Jorion is a professor of finance at UC Irvine’s Paul Merage School of Business and one of the most cited authorities on quantitative risk management in the world. He holds a PhD from the University of Chicago and has contributed the risk management curriculum used by the CFA Institute. His work on Value at Risk became the technical foundation for the Basel II and Basel III international banking regulations — meaning his framework has directly shaped how every major bank on earth measures risk.
Power Quote From the Book:
“The greatest danger of VaR is that it gives a false sense of security.”
— Philippe Jorion, Value at Risk
