The U.S. Treasury has revised its data indicating which nation’s institutions through the end of the U.S. government’s 2011 Fiscal Year, which ended on 30 September 2011. With that revision, we’ve updated our chart revealing who the biggest holders of all the U.S. government’s public debt outstanding were as of 30 September 2011:

Compared to the preliminary version of this chart, we see a large decrease in debt appearing to be held by the United Kingdom, but large increases in debt actually held by other foreign entities. This is due to the role of financial institutions in the U.K. acting as international intermediaries for the interests of other foreign entities. The Treasury Department’s annual revision of this data accounts for the actual foreign ownership of U.S. government-issued debt.

We note that some $1,773 billion of the U.S. government-issued debt we’ve recorded as being held by U.S. individuals and institutions as of 30 September 2011 was held by the U.S. Federal Reserve.

The U.S. Federal Reserve then accounts for 28% of all the debt held by U.S. individuals and institutions and works out to be nearly 12% of all the nation’s public debt outstanding, as the Federal Reserve increased its U.S. debt holdings by $807 billion during the U.S. governments 2011 fiscal year.

Combined, the U.S. government-issued debt holdings of foreign individuals and institutions account for just shy of one-third of all the U.S. government’s public debt outstanding.
