The exchange rate, in the long run, needs to be at the level which a basket of goods costs the same in two currencies. Thus, if a Mickey Mantle rookie card, for instance, costs $50,000 Canadian and $25,000 U.S., the exchange rate should be two Canadian dollars for one American dollar. Foreign exchange is important for one major reason: it determines the value of foreign investment. A volatile exchange rate discourages foreign investment, as does a high, stable one. A low, stable exchange rate, however, encourages foreign investment, but at the price of the low-valued currency's economy. The following exchange rates are certified by the Federal Reserve Bank of New York for customs purposes as required by section 522 of the amended Tariff Act of 1930. These rates are also those required by the SEC for the integrated disclosure system for foreign private issuers.
