Foreign Holdings of Federal Debt

Summary
This report presents current data on estimated ownership of U.S. Treasury securities and major
holders of federal debt by country. Federal debt represents the accumulated balance of borrowing
by the federal government. To finance federal borrowing, U.S. Treasury securities are sold to
investors. Treasury securities may be purchased directly from the Treasury or on the secondary
market by individual private investors, financial institutions in the United States or overseas, and
foreign, state, or local governments. Foreign investment in federal debt has grown in recent years,
prompting questions on the location of the foreign holders and how much debt they hold.
This report will be updated annually or as events warrant.

Foreign Holdings of Federal Debt

Selected Statistics on Foreign Holdings of
Federal Debt

Federal debt represents, in large measure, the accumulated balance of federal borrowing of the
U.S. government. The portion of gross federal debt held by the public consists primarily of
investment in U.S. Treasury securities.1 Investors in the United States and abroad include official
institutions such as the U.S. Federal Reserve, financial institutions such as private banks, and
private individual investors.
Table 1 provides December 2010 data, available as of March 2011, on estimated ownership of
U.S. Treasury securities by type of investment and the percentage of that investment attributable
to foreign investors.2
As the table shows, during the five years from December 2005 to December 2010 foreign
holdings of debt increased by $2.3 trillion to more than $4.3 trillion. During the same period, total
privately held debt increased by approximately $4.4 trillion to $8.4 trillion.3
In December 2005, total foreign investment in U.S. federal debt was approximately $2 trillion
(51.2%) of the total of approximately $4 trillion in privately held debt. By December 2010, total
foreign investment in U.S. federal debt had grown by 1 percentage point to approximately $4.4
trillion (52.2%) of the total of approximately $8.4 trillion in debt held by private investors.4 The
foreign-held share of the federal debt in 2009 and 2010 was slightly lower than the share in 2007
and 2008 because the overall debt grew more quickly than foreign holdings of the debt.

2 This report discusses foreign holdings of U.S. federal debt. Foreign investors also hold U.S. private securities. For
data on foreign holdings of U.S. private securities, see “Foreign Portfolio Holdings of U.S. Securities,” at
http://www.treasury.gov/resource-center/data-chart-center/tic/Pages/fpis.aspx, produced by the Treasury Department
International Capital System.
3 The publicly held federal debt includes Federal Reserve holdings. The privately held federal debt excludes them.
4 Data are excerpted from Table OFS-2 in the March 2010 Treasury Bulletin. Table OFS-2 presents the estimated
ownership of U.S. Treasury securities. Information is primarily obtained from the Federal Reserve Board of Governors
Flow of Funds data, Table L209. State, local, and foreign holdings include special issues of nonmarketable securities to
municipal entities and foreign official accounts. They also include municipal, foreign official, and private holdings of
marketable Treasury securities.

Although gross federal debt is the broadest measure of the debt, it may not be the most important one. The
debt measure that is relevant in an economic sense is debt held by the public. This is the measure of debt that
has actually been sold in credit markets and has influenced interest rates and private investment decisions. This
table reflects that portion of public debt held by all private investors in federal securities and the portion of that
debt held by foreign investors. See CRS Report RL31590, The Federal Government Debt: Its Size and Economic
Significance, by Brian W. Cashell.
Data on major foreign holders of federal debt by country are provided in Table 2. According to
the data, the top three estimated foreign holders of federal debt by country, ranked in descending
order as of December 2010, are China ($1,160.1 billion), Japan ($882.3 billion), and the United
Kingdom ($272.1 billion). Based on these estimates, China holds approximately 26.1% of all
foreign investment in U.S. privately held federal debt; Japan holds approximately 19.9%; and the
United Kingdom holds approximately 6.1%.5

Foreign holdings as estimated by the Treasury Department can be divided into official
(governmental investment) and private sources. Figure 1 provides data on the current breakdown
of estimated foreign holdings in U.S. federal debt. As the figure shows, 71.1% of foreign holdings
in U.S. federal debt are held by governmental sources. Private investors hold the other 28.9%.

Foreign Investment in U.S. Federal Debt: Why Is It
an Issue of Concern?

Foreign ownership of federal debt has become a growing concern among some Members of
Congress because of the nation’s large and rising trade deficit. During the past three decades, U.S.
national saving has not been adequate to finance its capital investment needs, and borrowing from

abroad has covered the gap. For foreigners to invest in the U.S. economy on net, the United States
must import more than it exports (run a trade deficit). When the government runs a budget deficit,
as it has done since 2002, it reduces the national saving rate. This implies that domestic
investment must fall, unless private saving rises or borrowing from abroad increases.6
As seen in Table 1, as the national debt has increased, foreign ownership of U.S. Treasuries has
followed closely, suggesting that the budget deficit has been financed, in part, through borrowing
abroad. By June 2004, foreigners held more than 50% of the public debt held by private investors
for the first time. Although this percentage has no particular economic significance, it may have
other significance.
Since 2002, some observers have been concerned that the nature of foreign purchases of U.S.
Treasuries has changed. Beginning in that year, a significant fraction of the trade deficit was
financed through official purchases of U.S. assets, such as purchases by foreign central banks.
Although no direct data on official purchases of Treasuries by country exist, it can be inferred that
the Treasuries may have been purchased by certain Asian and oil-producing countries because
they were the only countries that had large increases in their foreign reserves during that period.
Although the effect on the U.S. economy of official purchases of Treasuries is the same as private
purchases, the motivations behind the purchases are different. Whereas private purchases are
typically motivated by the profit incentive, official purchases may be motivated by a country’s
desire to keep its exchange rate constant or mitigate its rise against the dollar.7 Many observers
are concerned that the large fraction of national debt held by foreigners has the potential to be
harmful to the U.S. economy. Specifically, they fear that if foreigners suddenly decided to stop
holding U.S. Treasury securities or decided to diversify their holdings, the dollar could plummet
in value and interest rates would rise. Others are concerned that the accumulation of U.S. assets
by foreign governments, such as China, will give those governments leverage that may be applied
to the detriment of U.S. interests. Some economists also argue that foreign borrowing at current
levels is unsustainable and could cause problems for the U.S. economy down the road.8
When the United States borrows through sales of U.S. Treasuries to foreign purchasers, or sales
of any U.S. asset to foreign purchasers, the overall interest rates in the United States move slower
than if the borrowing would have been financed domestically out of national saving. Then
because interest rates are lower as a result of net capital inflows, more interest-sensitive spending
is undertaken. Interest-sensitive spending includes capital investment (e.g., production plants and
equipment), residential investment (e.g., new homes), and durable consumption goods (e.g.,
automobiles and appliances). On the other hand, U.S. foreign borrowing induces a trade deficit by
reducing exports and import-competing production. The trade deficit occurs because foreigners
must first purchase U.S. dollars before purchasing U.S. assets. When the demand for dollars
increases, the dollar appreciates, making U.S. exports and import-competing goods relatively
more expensive. Thus, foreign borrowing shifts production away from exports and into interest-
sensitive sectors.9

Foreign Holdings of Federal Debt

Since the financial turmoil began in August 2007, the supply of Treasury securities has risen
sharply, as a result of the increase in federal borrowing to finance spending on economic and
financial recovery. At the same time, the demand for Treasury securities has risen as there has
been greater investor preference for Treasury securities compared with riskier private securities.
Thus, although an increase in the supply of Treasury securities would be expected to cause
Treasury yields to rise, they instead fell relative to pre-crisis levels. Foreign demand has
contributed to the low yields that have allowed the U.S. government to finance large deficits at
low cost, though some fear that same foreign demand could prove transient in the future.
