Satellite Model

From Open Risk Manual

Definition

A Satellite Model denotes a Risk Model that is used to translate a given Macro Economic Scenario into Risk Parameters at the firm level

Context

The concept of distinct satellite risk models emerged in the context of post-crisis large scale Stress Testing activities organized by banking regulators worldwide. A key design of these stress testing exercises is that a set of common scenarios are specified as applying to all firms and those are then translated into specific firm models using proprietary firm specific data.[1]

Types of Satellite Models

  • Credit Risk
    • Probability of default (PD) models
    • Loss given default (LGD) models
  • Interest Rate Risk
  • Net Interest Margin
  • Fee's and Commission Income

Issues and Challenges

  • Market and Operational Risk are not easy to integrate into a macro-economic scenario stress testing framework
