US debt owed to foreigners totalled $7.625 trillion at the end of June, up 3.2 percent from the $7.392 trillion seen at the end of March, the Treasury Department said on Thursday.
The external debt data cover government and private bank debt owed to foreign investors, governments, banks and monetary authorities.
Treasury first published the data in October 2003 in an effort to comply with the International Monetary Fund's Special Data Dissemination System guidelines for economic data.
In the quarterly release, the Treasury said $1.454 trillion in principal and $61.99 billion in interest payments were due within three months in June. That was down from the $1.488 trillion in principal and $58.25 billion in interest that was due in three months at the end of March.

The report may underscore worries about the ability of the United States to fund its current account deficit.
The shortfall in the broadest measure of trade and investment flows between the United States and the rest of the world grew to a record $166.18 billion in the second quarter, according to Commerce Department data.
