Operational Hedges and Foreign-Exchange Exposure: The Experience of U.S. MNCs During the Asian Financial Crisis

This study provides evidence on the importance of operational hedges in foreign-exchange risk management, an issue that has been largely ignored in the literature. One possible reason for the absence of empirical evidence in the literature may be related to the difficulty in devising the appropriate measures of a firm's ability to construct operating hedges. We utilize measures of the structure of an MNC's foreign subsidiary network as proxies of the firm's ability to devise operational hedges and examine their relationship to exposure coefficients computed prior to and during the 1997–1998 Asian currency crisis. Our results show that the mean exposure during the Asian crisis period was significantly higher than the pre-crisis period. In addition, the mean of the absolute change in the exposure of MNCs that only operate in the Asian crisis region was significantly higher than that of MNCs without operations in the crisis region. We find a strong relationship between our proxies for ability to construct operating hedges and exchange-rate exposure measures both prior to the crisis and during the crisis. An even stronger association between exposure and measures of the MNC network structure is found for the sub-sample of MNCs that have some operations in the Asian crisis region. Similar results are obtained when the relationship is examined separately for “net importers” (MNCs with positive exposures) and “net exporters” (MNCs with negative exposures). Overall, our results are consistent with the notion that operational hedges significantly reduce a firm's exposure to foreign-exchange risk.
