One of the chief advantages of the VaR approach is that it assesses exposure to
different markets (interest rates, foreign exchange, etc) in terms of a common base –
losses relative to a standard unit of likelihood. Hence, risks across different
instruments, traders and markets can be readily compared and aggregated. In
addition, a dollar-value VaR can be directly compared to actual trading profit and
loss results – both as a means of testing the adequacy of the VaR model and to
assess risk-adjusted performance. Risk-adjusted returns can be quantified simply by
looking at the ratio of realised profits/losses to VaR exposure. Such calculations
provide a basis for a bank to develop sophisticated capital-allocation models and to
renumerate individual traders not just for the volume of trading done, but to reflect
the riskiness of each trader’s activities.
