The U.S. government’s 2017 fiscal year officially ended on 30 September 2017. From the end of its 2016 fiscal year (FY2016) a year earlier, the total public debt outstanding of the U.S. government increased by $671.5 billion, rising from $19,573 billion (or $19.6 trillion) to $20,245 billion (or $20.2 trillion) during FY2017.
The following chart shows the major breakdown of who the U.S. government has borrowed that total $20.2 trillion from:
According to the U.S. Treasury Department, the U.S. government spent some $665.7 billion more than it collected in taxes during its 2017 fiscal year. The difference between this figure and the $671.5 billion that the total national debt actually rose can be attributed to the government’s net borrowing to fund things like Federal Direct Student Loans, which collectively account for nearly $1.1 trillion of the government’s $20.2 trillion debt, or 5.4% of the total public debt outstanding.
Put differently, the U.S. national debt would be 5.4% less at roughly $19.1 trillion if not for the federal government’s takeover of the student loan industry from the private sector in March 2010. Since that time, approximately $1 of every $10 that the U.S. government has borrowed has been for the purpose of funding its student loan program.
Overall, 69% of the U.S. government’s total public debt outstanding is held by U.S. individuals and institutions, while 31% is held by foreign entities. China has resumed its position as the top foreign holder of U.S. government-issued debt, with directly accounting for 6.9% between institutions on the Chinese mainland and Hong Kong.
Beyond that, China likely has additional holdings that are currently being shown as being held in the international banking centers of Belgium and Ireland, which together account for 2.0% of the U.S. national debt, where China’s holdings are believed to represent a significant portion of the amounts currently being credited to both these nations.
