Which Countries Hold the Most U.S. Debt in 2022?
Today, America owes foreign investors of its national debt $7.3 trillion.
These are in the form of Treasury securities, some of the most liquid assets worldwide. Central banks use them for foreign exchange reserves and private investors flock to them during flights to safety thanks to their perceived low default risk.
Beyond these reasons, foreign investors may buy Treasuries as a store of value. They are often used as collateral during certain international trade transactions, or countries can use them to help manage exchange rate policy. For example, countries may buy Treasuries to protect their currency’s exchange rate from speculation.
In the above graphic, we show the foreign holders of the U.S. national debt using data from the U.S. Department of the Treasury.
Top Foreign Holders of U.S. Debt
With $1.1 trillion in Treasury holdings, Japan is the largest foreign holder of U.S. debt.
Japan surpassed China as the top holder in 2019 as China shed over $250 billion, or 30% of its holdings in four years.
This bond offloading by China is the one way the country can manage the yuan’s exchange rate. This is because if it sells dollars, it can buy the yuan when the currency falls. At the same time, China doesn’t solely use the dollar to manage its currency—it now uses a basket of currencies.
Here are the countries that hold the most U.S. debt:
|Rank||Country||U.S. Treasury Holdings||Share of Total|
|3||🇬🇧 United Kingdom||$655B||8.9%|
|6||🇰🇾 Cayman Islands||$284B||3.9%|
|11||🇭🇰 Hong Kong||$221B||3.0%|
|16||🇸🇦 Saudi Arabia||$120B||1.6%|
|17||🇰🇷 South Korea||$103B||1.4%|
As the above table shows, the United Kingdom is the third highest holder, at over $655 billion in Treasuries. Across Europe, 13 countries are notable holders of these securities, the highest in any region, followed by Asia-Pacific at 11 different holders.
A handful of small nations own a surprising amount of U.S. debt. With a population of 70,000, the Cayman Islands own a towering amount of Treasury bonds to the tune of $284 billion. There are more hedge funds domiciled in the Cayman Islands per capita than any other nation worldwide.
In fact, the four smallest nations in the visualization above—Cayman Islands, Bermuda, Bahamas, and Luxembourg—have a combined population of just 1.2 million people, but own a staggering $741 billion in Treasuries.
Interest Rates and Treasury Market Dynamics
Over 2022, foreign demand for Treasuries sank 6% as higher interest rates and a strong U.S. dollar made owning these bonds less profitable.
This is because rising interest rates on U.S. debt makes the present value of their future income payments lower. Meanwhile, their prices also fall.
As the chart below shows, this drop in demand is a sharp reversal from 2018-2020, when demand jumped as interest rates hovered at historic lows. A similar trend took place in the decade after the 2008-09 financial crisis when U.S. debt holdings effectively tripled from $2 to $6 trillion.
Driving this trend was China’s rapid purchase of Treasuries, which ballooned from $100 billion in 2002 to a peak of $1.3 trillion in 2013. As the country’s exports and output expanded, it sold yuan and bought dollars to help alleviate exchange rate pressure on its currency.
Fast-forward to today, and global interest-rate uncertainty—which in turn can impact national currency valuations and therefore demand for Treasuries—continues to be a factor impacting the future direction of foreign U.S. debt holdings.
Ranked: The World’s Top Diamond Mining Countries, by Carats and Value
Who are the leaders in rough diamond production and how much is their diamond output worth?
Ranked: World Diamond Mining By Country, Carat, and Value
Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.
This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.
Rough Diamond Production, By Weight
Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.
Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.
Here’s a quick breakdown of rough diamond production in the world.
|5||🇿🇦 South Africa||9,660,233|
|10||🇸🇱 Sierra Leone||688,970|
|18||🇨🇮 Cote D'Ivoire||3,904|
|19||🇨🇬 Republic of Congo||3,534|
Note: South Africa’s figures are estimated.
As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.
Diamond Mining, by Country
However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.
Here’s a quick breakdown of diamond production by value (USD) in 2022.
|5||🇿🇦 South Africa||$1,538M|
|9||🇸🇱 Sierra Leone||$143M|
|19||🇨🇬 Republic of Congo||$0.20M|
|20||🇨🇮 Cote D'Ivoire||$0.16M|
Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.
Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.
Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.
Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.
Which Regions Produce the Most Diamonds in 2022?
Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.
|Rank||Region||Share of Rough|

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.
By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.
And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.
