Morgan 1994 annual report VAR summarizes the expected maximum loss (or worst loss) over a target horizon (day/month) within a given confidence interval. It allows us to estimate company-wide risks in one number and compare across different companies/markets It is now widely used in firms and banks.,18,Value at Risk (VAR): for general distribution and an example,Define W0 as initial investment, R rate of return, then at the end of the day/month, W=W0(1+R). Denote the expected return as and volatility of R as ; and the lowest portfolio value at the given confidence level c as W*=W0(1+R*). VAR is defined as the dollar loss relative to the mean, Value at Risk (mean)=E(W)-W*= - W0(R*- ) (1) J.P. Morgans distribution of daily revenue in 1994: Mean revenue is $5.1m, n=254. Select c=95%, 254x5%=12.7. In the chart, we find the 5% of occurrences (15 obs) below -$9m. After interpolating, we find W*= -$9.6m The VAR of daily revenues, relative to the mean is VAR = E(W) W*= $5.1m- (-$9.6m) = $14.7m (2) Absolute VAR=$9.6m,19,Short Term Capital Flows are Linked to Financial Fragility: Short term debt/reserve ratios peaked before crises,Source: GDF, 1999,20,Short Term Debt /Reserve Ratios are good warning indicators of financial fragility: It peaked before the Peso crisis,Source: GDF, 1999,21,Short-term Debt as percent of international reserves: a liquidity index,22,Short-term Debt as percent of international reserves: a good warning indicator,23,GDP growth and growth of short-term debt: Pro-cyclical to growth and exacerbate boom/bust,24,GDP growth and growth of short-term debt: Pro-cyclical to growth and exacerbate crises,25,III.
