Value at Risk (VaR)
Value at Risk (VaR) has come to be regarded as the premier risk management technique for the financial industry. It measures the probability-based measure of potential loss that can be measured for specific transactions, business units or the total enterprise.
VaR estimates the loss in money terms that could be exceeded (i.e. it represents the minimum loss) at a given level of probability. For example, a $5 million one-day VaR at 5% indicates a 5% chance that losses could exceed $5 million on a given day.
All else equal, a higher loss has a lower probability of occurrence. Likewise, reducing the probability level from 5% to 1% (the two most common levels in use) would result in a higher VaR at the lower probability level.
