Investopedia explains Trade Deficit
Economic theory dictates that a trade deficit is not necessarily a bad situation because it often corrects itself over time. However, a deficit has been reported and growing in the United States for the past few decades, which has some economists worried. This means that large amounts of the U.S. dollar are being held by foreign nations, which may decide to sell at any time. A large increase in dollar sales can drive the value of the currency down, making it more costly to purchase imports.
