Applying currency correlations to net cash flows (Exhibit 10.7)
If a MNC has positive net cash flows in various currencies that are highly correlated, it may be exposed to a relatively high level exchange rate risk. However, many MNCs have some negative net cash flow positions in some currencies to complement their positive net cash flows in other currencies.
Currency correlations over time
Because currency correlations change over time, an MNC cannot use previous correlations to predict future correlations with perfect accuracy.
