Example 1 Suppose that a financial institution has bought 10 million shares of one company and 50 million ounces of a commodity.The shares are bid $89.5,offer$90.5. The commodity is bid $15, offer $15.1. The cost of liquidation in a normal market is ? The mid-market value of the position in the share is 90×10=900 million; in the commodity is 15.05×50=752.50million the bid-offer spread for share is 1/90= 0.01111 for commodity is 0.1/15.05=0.006645 cost of liquidation 900×0.01111×1/2+752.5×0.006645×1/2=7.5million Example 2 Suppose that in Example 1 the mean and standard deviation for the proportional bid-offer spread for the shares are0.01111 and 0.02222; for the commodity are both 0.006645. Assuming that the spreads are normally distributed, the cost of liquidation that we are 99% confident,thatλ=2.33 900×1/2(0.01111+2.33×0.02222)+752.5×(0.006645+2.33×0.006645)=73.25 Risk Management and Financial Institutions 2e, Chapter 19, Copyright ?
