As of April 28, 2009 the International Reserve Position of the United States shows total foreign exchnage reserves of $ 75, 877 million - or around $ 76b, according to this press release from the Department of the Treasury.
According to a Treasury statement to the Associated Press, The US Treasury plans to borrow $361 billion in the current April to June Quarter. Excerpt:
The $361 billion estimate for borrowing this quarter compared with borrowing needs of just $13 billion in the year-ago period. Normally the government's borrowing needs shrink sharply in the April-June quarter because of all the tax revenue being collected.
But, please remember:
Treasury also estimated it will need to borrow $515 billion in the July-September quarter, down slightly from the $530 billion borrowed during the year-ago period. The all-time high of $569 billion was set in the October-December period.
