Information Technology Considerations
In the first 39 chapters of this book, we reviewed the tools necessary to construct a fully integrated measure of interest rate risk, market risk, liquidity risk, foreign exchange risk, and credit risk. This measure, the Jarrow-Merton put option, produces an answer to the key question “What is the hedge?” Some of the tools we have discussed were focused on risk management strategy, such as usage of the Jarrow-Merton put option as a comprehensive measure of risk. Other tools have been more mechanical, such as how to value an American call option embedded in a bond when the default of the issuer is a possibility. In this chapter, we focus on another set of issues that have to be faced when implementing a comprehensive risk management system—the information technology aspects of an implementation.
The authors collectively have spent 105 years in the implementation of risk systems in major financial institutions in 23 countries around the world, and our comments below reflect the worldwide best practice in that regard.
