48. A US-based corporation has decided to make an investment in Norwegian Kroner of NOK 500 Million (NOK = Norwegian Kroner) in 3 months. The company wishes to hedge changes in the the US dollar-NOK exchange rate using forward contracts on either the euro (EUR) or the Swiss Franc (CHF). The company makes the following estimates:

•If EUR forwards are used: The standard deviation of quarterly changes in the USD/NOK spot exchange rate is 0.005, the standard deviation of quarterly changes in the USD/EUR forward rate is 0.025, and the correlation between the changes is 0.90.

•If CHF forwards are used: The standard deviation of quarterly changes in the USD/NOK spot exchange rate is 0.005, the standard deviation of quarterly changes in the USD/CHF forward rate is 0.020, and the correlation between the changes is 0.80.

The current USD/NOK spot rate is 0.160 (i.e., USD 0.160 per NOK), the current 3-month USD/EUR forward rate is 1.36, and the current 3-month USD/CHF forward rate is 1.04.
