Foreign Holdings of Federal Debt 
 
Summary 
This report presents current data on 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. The gross debt is composed of debt held by the public and intragovernmental 
debt held by federal trust funds. To finance the publicly held debt, 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; the Federal Reserve; financial institutions in the 
United States or overseas; and foreign, state, or local governments.  
As of December 2023, there was $26.2 trillion of Treasury securities outstanding, up from $16.6 
trillion in December 2019, a $9.6 trillion increase (figures are rounded). During the same period, 
foreign holdings of debt increased by $1.1 trillion to a total of approximately $8.1 trillion. After 
staying relatively flat in dollar terms for several years, overall foreign holdings increased in 2019-
2021, fell in 2022, then jumped in 2023. Because the total debt has increased faster than the debt 
held by foreigners, the share of federal debt held by foreigners has declined in recent years. In 
December 2023, foreigners held 31% of the publicly held debt. Interest on the debt paid to 
foreigners in 2023 was $197.5 billion. 
Foreign holdings can be divided into official (governmental investment) and private sources: 
47.7% ($3.8 trillion) of foreign holdings in U.S. federal debt are held by governmental sources, 
and private investors hold the other 52.3% ($4.2 trillion).  
Including private investors and governments, the top three estimated foreign holders of federal 
debt by country, as of December 2023, are Japan ($1.1 trillion), China ($0.8 trillion), and the 
United Kingdom ($0.7 trillion). Based on these estimates, Japan holds approximately 14.3% of all 
foreign investment in U.S. publicly held federal debt, China holds approximately 10.3%, and the 
United Kingdom holds approximately 8.5%.  
From an economic perspective, foreign holdings of federal debt can be viewed in the broader 
context of U.S. savings, investment, and borrowing from abroad. For decades, the United States 
has saved less than it invests. Domestic saving is composed of saving by U.S. households, 
businesses, and governments. By accounting identity, when the government runs budget deficits, 
it reduces domestic saving. By the same accounting identity, the shortfall between U.S. saving 
and physical investment is met by borrowing from abroad. To be a net borrower from abroad, the 
United States must run a trade deficit (i.e., it must buy more imports from foreigners than it sells 
in exports to foreigners). Borrowing from abroad has occurred through foreign purchases of both 
U.S. government and U.S. private securities and other assets. 
As a result of foreign purchases of Treasury securities, the federal government must send U.S. 
income abroad to foreigners. If the overall economy is larger as a result of federal borrowing 
(because the borrowing stimulated economic recovery or was used to productively add to the U.S. 
capital stock, for example), then this outcome may leave the United States better off overall on 
net despite the transfer of income abroad. In other words, without foreign borrowing, U.S. income 
would be lower than it currently is net of foreign interest payments in this scenario.

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 gross debt is composed of debt held by the public and intragovernmental 
debt held by federal trust funds. Although gross federal debt is the broadest measure of the debt, 
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. Intragovernmental debt, by contrast, is both an asset and a liability 
to the federal government. 
The portion of gross federal debt held by the public consists primarily of investment in 
marketable U.S. Treasury securities (i.e., bills, bonds, and notes traded in private markets).1 
Investors in the United States and abroad include official institutions, such as the U.S. Federal 
Reserve and foreign central banks; financial institutions, such as commercial banks; and private 
individual investors. 
Table 1 provides December 2019 through December 2023 data, available as of June 2024, on 
estimated ownership of U.S. Treasury securities by type of investment and the percentage of that 
investment attributable to foreign investors.2 
The table shows that during this period, foreign holdings of debt increased by $1.1 trillion to 
approximately $8.1 trillion. After staying relatively flat in dollar terms for several years, overall 
foreign holdings increased in 2019-2021, fell in 2022, and then jumped in 2023. During the same 
period, total publicly held debt increased by approximately $9.6 trillion from $16.6 trillion to 
$26.2 trillion.3 Because the total debt has increased faster than the debt held by foreigners, the 
share of federal debt held by foreigners has declined in recent years. In December 2023, 
foreigners held 31% of the publicly held debt.4 Interest on the debt paid to foreigners in 2023 was 
$197.5 billion.5

Foreign Investment in U.S. Federal Debt: 
Why Is It an Issue of Concern? 
From an economic perspective, foreign holdings of federal debt can be viewed in the broader 
context of U.S. saving, investment, and borrowing from abroad. For decades, the United States 
has saved less than it invests. Domestic saving is composed of saving by U.S. households, 
businesses, and governments. By accounting identity,8 when the government runs budget deficits, 
it reduces domestic saving. By the same accounting identity, the shortfall between U.S. saving 
and physical investment is met by borrowing from abroad. When the deficit rises (i.e., public 
saving falls), U.S. investment must fall (referred to as the deficit crowding out investment) or 
borrowing from abroad must rise. If capital were fully mobile and unlimited, a larger deficit 
would be fully matched by greater borrowing from abroad, and there would be no crowding out 
of domestic investment.  
By accounting identity, to be a net borrower from abroad, the United States must run a current 
account deficit. The trade deficit is the largest component of the current account deficit.9 In other 
words, to be a net borrower, the United States must buy more imports from foreigners than it sells 
in exports to foreigners. Since 2000, U.S. borrowing from abroad and the trade deficit have each 
exceeded $300 billion each year. Borrowing from abroad equaled $832 billion in 2023, down 
from a high of $976 billion in 2022.10 Borrowing from abroad has occurred through foreign 
purchases of both U.S. government and U.S. private securities and other assets.11 
As a result of foreign purchases of Treasury securities, the federal government must send U.S. 
income abroad to foreigners. If the overall economy is larger as a result of federal borrowing 
 
8 The accounting identity is (household saving + business saving + government saving) + (borrowing from abroad - 
lending to abroad) = (public investment + private investment). 
9 The current account also includes net income and transfer payments made by the United States.

(because the borrowing stimulated economic recovery12 or was used to productively add to the 
U.S. capital stock, for example), then this outcome may leave the United States better off overall 
on net despite the transfer of income abroad. In other words, without foreign borrowing, U.S. 
income would be lower than it currently is net of foreign interest payments in this scenario.  
It can be argued that the underlying long-term economic issue is the budget deficit itself and not 
that the deficit is financed in part by foreigners. This can be illustrated by the counterfactual. 
Assume the same budget deficits and U.S. saving rates without the possibility of foreign 
borrowing. In this case, budget deficits would have had a much greater crowding-out effect on 
U.S. private investment, because only domestic saving would have been available to finance both. 
The pressures the deficit has placed on domestic saving would have pushed up interest rates 
throughout the economy and caused fewer private investment projects to be profitably 
undertaken. With fewer private investment projects, overall GDP would have been lower over 
time relative to what it would have been. The ability to borrow from foreigners avoids the 
deleterious effects on U.S. interest rates, private investment, and GDP, to an extent, even if it 
means that the returns on some of this investment now flow to foreigners instead of Americans. In 
other words, all else equal, foreign purchases of Treasury securities reduce the federal 
government’s borrowing costs and reduce the costs the deficit imposes on the broader economy. 
The burden of a foreign-financed deficit is borne by exporters and import-competing businesses, 
because borrowing from abroad necessitates a trade deficit. It is also borne by future generations, 
because future interest payments will require income transfers to foreigners.13 To the extent that 
the deficit crowds out private investment rather than being financed through foreign borrowing, 
its burden is also borne by future generations through an otherwise smaller GDP. As interest rates 
have increased in recent years, interest paid on Treasury securities (to both Americans and 
foreigners)14 has risen rapidly. If rates do not fall, the burden will continue to rise as old debt 
matures and is rolled over into new debt instruments with higher rates. 
Thus far, this report has considered the impact of the government’s budget deficit and the low 
U.S. saving rate on U.S. Treasury yields but not investor demand. Since interest rates fell to 
historic lows at a time when the supply of Treasury securities rose to historic heights, it follows 
that Treasury rates have been driven mainly by increased investor demand in recent years. In the 
wake of the 2008 financial crisis and again during the COVID-19 pandemic, investor demand for 
Treasury securities increased as investors undertook a flight to safety. Treasury securities are 
perceived as a safe haven compared with other assets because of low perceived default risk and 
greater liquidity (i.e., the ability to sell quickly and at low cost) than virtually any alternative 
asset. For foreign investors, their behavior also implies that they view the risk from exchange rate 
changes of holding dollar-denominated assets to be lower than alternative assets denominated in 
other currencies. The reasons for this flight to safety are varied. For example, investors who had 
previously held more risky assets may become more averse to risk and seek to minimize their loss 
exposure; investors may not see profitable private investment opportunities and choose to hold 
their wealth in Treasury securities as a store of value until those opportunities arise; or investors 
may need Treasury securities to post as collateral for certain types of transactions (such as

Economic Effects, by Lida R. Weinstock. 
13 See CRS Report RL30520, The National Debt: Who Bears Its Burden?, by Marc Labonte. Income transfers to 
domestic debt holders have no net cost on the United States because they transfer income from one group of Americans 
(taxpayers) to another (bond holders).

repurchase agreements) where previously other types of collateral could be used (or used at low 
cost).  
Flight-to-safety considerations have subsided as economic conditions have normalized, reducing 
the incentive for foreigners to buy Treasuries and raising their yields, all else equal. But Treasury 
securities are also sought out by international investors because of the dollar’s unique role as the 
world’s reserve currency. As a result, Treasury securities are in permanent demand as underlying 
collateral in financial transactions and as a temporary store of value while trade or financial 
transactions are being executed. Treasury securities may also be relatively attractive compared to 
other government’s bonds because, for a variety of reasons, Treasury yields tend to be slightly 
higher, when adjusted for risk. 
More normal economic conditions have also increased domestic investment demand, which has 
both pushed up domestic interest rates and lead to more foreign borrowing. This relative 
movement in rates could attract additional foreign capital inflows. 
Additionally, any discussion of foreign holdings of Treasuries would be incomplete without a 
discussion of the large holdings of foreign governments (referred to as foreign official holdings in 
Figure 3).15 Foreign official holdings are motivated primarily by a desire for a liquid and stable 
store of value for foreign reserves. Relatively few assets besides U.S. Treasury securities fill this 
role well. Depending on the country, foreign reserves may be accumulated as a result of a 
country’s exchange rate policy, the desire to reinvest export proceeds, or the desire to build a war 
chest to fend off speculation against the country’s exchange rate and securities. If motivated by 
any of these factors, rate of return may be a lesser consideration for foreign governments than it is 
for a private investor, although large, foreign official holdings have not been significantly 
increasing since 2013—and peaked in 2020—after more than a decade of rapid growth before 
then. 
Since 1986, the United States has had a net foreign debt, and that debt was roughly $19.8 trillion 
in 2023.16 Additional growth in net foreign debt would be unsustainable in the long run if it grows 
faster than GDP, as it has generally done in recent decades. This net foreign debt has not imposed 
any burden on Americans thus far, however, because the United States has consistently earned 
more income on its foreign assets than it has paid on its foreign debt, even though foreigners 
owned more U.S. assets than Americans owned foreign assets. Although it is likely that the 
United States would begin to make net debt payments to foreigners at some point if the net 
foreign debt were to continue to grow, it has not occurred yet. To date, the primary drawback is 
the risk that its unsustainable growth poses, although that risk is slight in the short run. 
Unsustainable growth in the net foreign debt could lead to foreigners at some point reevaluating 
and reducing their U.S. asset holdings. If this happened suddenly, it could lead to financial 
instability and a sharp decline in the dollar’s value. Alternatively, were the growth in the debt to 
decline gradually, it is unlikely to be destabilizing.17

between the foreign assets and foreign liabilities of U.S. residents. 
17 The “safe haven” role of Treasuries and “reserve currency” role of the dollar have led to counterintuitive outcomes—
lower Treasury yields in response to U.S. events with systemic risk potential, such as the subprime mortgage crisis and 
the federal debt downgrade. These counterintuitive outcomes make it even harder to accurately predict when the debt 
might become unsustainable and perhaps make a destabilizing reversal of capital flows less likely compared with other 
countries.

A related concern is whether the major role of foreigners in Treasury markets adds more risk to 
financial stability. In other words, would financial stability be less at risk if the United States 
borrowed the same amount from foreigners, but foreigners invested exclusively in private 
securities instead of U.S. Treasury securities? Empirical evidence does not shed much light on 
this question, although the fact that some foreign countries that experienced debt crises, such as 
Ireland, had accumulated mainly private, not government, debts might suggest that avoiding 
foreign ownership of government debt is not a panacea. Although countries such as Greece with 
large foreign holdings of government debt have experienced financing problems, a large share of 
Italy’s large government debt was held domestically, and it has nevertheless faced financing 
problems. The major role of foreign governments as holders of U.S. Treasuries could reduce 
financial instability if foreign governments are less motivated by rate-of-return concerns, because 
that implies they would be less likely to sell their holdings if prices started to fall. Finally, foreign 
official holdings of U.S. debt may have foreign policy (as opposed to economic) implications that 
are beyond the scope of this report. 
What policy options exist if policymakers decided foreign ownership of federal debt is 
undesirable? Absent strict capital controls, it is unlikely that foreigners could effectively be 
prevented from buying Treasury securities. After Treasury securities are initially auctioned by 
Treasury, they are traded on diffused and international secondary markets, and turnover is much 
higher on secondary markets than on initial auctions. A foreign ban on secondary markets would 
be hard to enforce because secondary market activity could shift overseas, and even if it could be 
enforced, the U.S. saving-investment imbalance would likely shift foreign investment into other 
U.S. securities—perhaps even newly created financial products that allowed foreigners to 
indirectly invest in Treasury securities. Thus, a ban would not address the underlying economic 
factors driving foreign purchases. Economically, the only way the U.S. government could reduce 
its reliance on foreign borrowing is by raising the U.S. saving rate, which could be done most 
directly by reducing budget deficits. Reducing deficits too quickly could be counterproductive, 
however, if it undermined an economic recovery.
