The total public debt consists of two components:
1) Debt held by the public which is $US 11.177 trillion today.
2) Intragovernmental debt which is $US 4.783 trillion today.
The sum of these two is almost $US 16 trillion. The debt held by the public is increasing very rapidly, while the intragovernmental debt is stable.
Of these two components, the first one can be held by foreigners.
