During the middle years of last decade, the exchange rate of the U. S. dollar has declined against the currencies of its major trading partners. You would expect this to result in a corresponding increase in U. S. dollar denominated import prices from those trading partners. U. S. dollar import prices, however, often rise less than the increase in the currency value of the exporter. Why

Because there are other factors that influence the weakening or strengthening of the dollar, not just the dollar exchange rate in relation to the exchange rates of other countries' currencies.

Explanation:

Although the United States has registered increases in the trade deficit, that is, when the country imports more goods and services from abroad than it exports, there are other factors that determine whether the country's currency is valued or not. In the case of the dollar, its value has not decreased despite the fall in the exchange rate of the dollar in relation to the currencies of its main trading partners due to the fact that the dollar is the main reserve currency in the world, which means that the dollar is the fashion of commercial transaction in the world, therefore its value is not lost in relation to other currencies, since several important transactions in the world such as gold and oil commodities are traded in dollars.

There is also the fact that the US attracts a lot of international investment for US Treasury bills, which helps to strengthen the dollar.
