My name is Muhammad and I hold a Master's degree in Commerce.
On the above list, the United States is at the top in the ranking. According to this report, the United States imports in billions of dollars which is $1,150, which is a huge amount. Now let me tell you something about mercantilism -- the trade theory.
According to the theory, countries should export more than they import and if a country imports more than it exports, then the BOP will be in deficit, but if a country exports more than it imports, then the BOP will be in surplus. According to this report which is about U.S. Total Goods and Services Trade (in billions of current U.S. dollars):
Description__ 2008 2009 2010 2011
Exports $1,842.7 1,578.9 1,842.5 2,103.4
Imports __$2,541.0 1,958.1 2,337.2 2,663.2
If we subtract $2,663.2 imports of the last year, from $2,103.4 in export, the answer will be 559.8, which means the U.S. imports more than they Export. That's why the BOP is in deficit.
The U.S. dollar's decline on the international market, well there are so many reasons and I think one of the reasons is the one i have already explained above.
