Setting Market Risk Limits – Learning Roadmap

Risk models only have value if they are used effectively in combination with limit management and control process. While a conventional view of the control function is that it requires and relies on reports, the key is not generation of quantitative numbers, formatted in ten different variation and cuts; it is the interpretation and application of the analysis behind that reports that matters.
The objective of a risk function is to not just gather data, run reports, submit and analyze them, it is to ensure that unpleasant surprises and their impact is limited. While you can’t control the timing and magnitude of such surprises, a well managed and well run risk function can help manage expectations as well as plan ahead for unexpected shocks. Limits play a major role in achieving that objective.
