WHAT IS ECONOMIC EXPOSURE?

PDVSA, the Venezuelan state-owned oil company, recently set up an oil refinery near Rotterdam, The Netherlands for shipment to Germany and other continental European countries. The firm planned to invoice its clients in ECU, the official currency unit of the European Community. The treasurer is considering sources of long term financing. In the past all long term finance has been provided by the parent company, but working capital required to pay local salaries and expenses has been financed in Dutch guilders. The treasurer is not sure whether the short term debt should be hedged, or what currency to issue long term debt in.
This is an example of a situation where the definition of exposure has a direct impact on the firm's hedging decisions.
Translation exposure has to do with the location of the assets, which in this case would be a totally misleading measure of the effect of exchange rate changes on the value of the unit. After all, the oil comes from Venezuela and is shipped to Germany: its temporary resting place, be it a refinery in Rotterdam or a tanker en route to Germany, has no import. Both provide value added, but neither determine the currency of revenues. So financing should definitely not be done in Dutch guilders.
Transactions exposure has to do with the currency of denomination of assets like accounts receivable or payable. Once sales to Germany have been made and invoicing in ECU has taken place, PDVSA-Netherlands has contractual, ECU-denominated assets that should be financed or hedged with ECU. For future sales, however, PDVSA-Netherlands does not have exposure to the ECU. This is because the currency of determination is the U.S. dollar.
Economic exposure is tied to the currency of determination of revenues and costs. Since the world market price of oil is dollars, this is the effective currency in which PDVSA's future sales to Germany are made. If the ECU rises against the dollar, PDVSA must adjust its ECU price down to match those of competitors like Aramco. If the dollar rises against the ECU, PDVSA can and should raise prices to keep the dollar price the same, since competitors would do likewise. Clearly the currency of determination is influenced by the currency in which competitors denominate prices.
