Exposure Netting (1)
A multinational firm should not consider deals in isolation, but should focus on hedging the firm as a portfolio of currency positions.
As an example, consider a U.S.-based multinational with Korean won receivables and Japanese yen payables. Since the won and the yen tend to move in similar directions against the U.S. dollar, the firm can just wait until these accounts come due and just buy won with yen.
Even if it’s not a perfect hedge, it may be too expensive or impractical to hedge each currency separately.
