Managing Foreign Exchange Risk
This chapter discusses the method's application to foreign exchange risk management by elaborating how to use foreign exchange options for hedging the interest rate risk. The problem is to determine how many European Put options to purchase for optimal hedging of the foreign exchange risk: 1) Stochastic Optimisation is used to construct Efficient Frontier of optimal hedging strategies of the foreign exchange risk with minimal Standard Deviation; 2) Monte Carlo simulation is utilised to stochastically calculate and measure the Total Amount Hedged (US $), Variance, Standard Deviation and VAR of Efficient Frontier optimal hedging strategies; 3) Six Sigma process capability metrics are also stochastically calculated against desired specified target limits for Total Amount Hedged and associated VAR of Efficient Frontier optimal hedging strategies; 4) Simulation results are analysed and the optimal hedging strategy is selected based on the criteria of minimal VAR.
