Apparently not if foreign holders of Treasuries are unloading them.
From November 2013 through January 2014 Belgium with a GDP of $480 billion purchased $141.2 billion of US Treasury bonds. Somehow Belgium came up with enough money to allocate during a 3-month period 29 percent of its annual GDP to the purchase of US Treasury bonds.
Certainly Belgium did not have a budget surplus of $141.2 billion. Was Belgium running a trade surplus during a 3-month period equal to 29 percent of Belgium GDP?
No, Belgiums trade and current accounts are in deficit.
