Mainland China has decreased its holdings of U.S. Treasury securities since last October, according to a report updated today by the U.S. Treasury Department.
Since September 2008, when they eclipsed Japan, entities in mainland China have been the largest foreign owners of U.S. government debt. But, as indicated by the Treasury Department chart linked here, Chinese ownership of U.S. Treasury securities peaked in October 2010 and has declined in each of the four most recent months reported by the Treasury Department.
In the two years between September 2008 and September 2010, China increased its U.S. government debt holdings by $533.7 billion—from $618.2 billion to 1.1519 trillion. By the end of October 2010, China’s holdings of U.S. government debt had increased to their peak of 1.1753 trillion.
After that, mainland Chinese holding of U.S. government debt declined for four straight months.
Entities in Hong Kong have also been decreasing their ownership of U.S. government debt. Hong Kong ownership of U.S. Treasury securities peaked at $152.4 billion in February 2010. By the end of February 2011, that had dropped to $124.6 billion.
