In fact, if you hold a U.S. Treasury bond or a T-Bill in your portfolio right now, you are already a creditor to the United States government. And as you can see in today’s chart from HowMuch.net, foreign countries like China and Japan can also accumulate large positions in U.S. Treasurys, making them significant players in the overall United States debt pie.
U.S. Debt: The Big Picture
The United States federal debt currently sits at $22 trillion, and it’s held by a range of domestic and foreign investors. As you can see, about $8.1 trillion of debt is held by departments of the U.S. government or the Federal Reserve. This number would include securities sitting in retirement accounts of federal employees, social security trust funds, or any of the Treasurys sitting on the Fed’s balance sheet. Next, another $7.6 trillion of debt is held by domestic investors. These are marketable securities held by banks, mutual funds, pension funds, insurance companies, and other investors. While debt held domestically is mostly uninteresting, a bigger question mark is the $6.3 trillion of debt that is owned by foreign countries. After all, couldn’t a country like China “weaponize” its large holdings of Treasury securities as a form of retaliation in the ongoing trade war?
Foreign Owners of the Debt
Internationally, the biggest owners of debt include China and Japan, each with over $1 trillion. Why does China hold so much of the foreign-owned U.S. debt? China has accumulated Treasury securities over decades, as part of its strategy to keep its domestic currency from strengthening. Interestingly, the export-heavy nation has reduced its swath of Treasurys in recent months, selling off close to $200 billion of them.
Although China has $1.11 trillion of Treasurys left in reserve, the general consensus is that dumping all of them at once would destabilize the global financial system, having an equally negative effect on China as well. That said, with foreign nations holding U.S. debt, such a risk will always exist.
Gimme Shelter
While it’s not surprising to see countries like China, Japan, or Brazil on the list of top foreign debt holders, what are places like the Cayman Islands, Luxembourg, or Ireland doing on the list?
Two simple facts help to explain these anomalies.
Firstly, despite having a population of just 60,000 people, the Cayman Islands is a hedge fund capital with over 10,000 funds domiciled there. Luxembourg makes the list for similar reasons, given that it is the European-based tax shelter equivalent.
Ireland, on the other hand, is the overseas headquarters for many U.S.-based tech giants like Facebook or Alphabet. Apparently, these corporations like to hold their overseas profits in highly-liquid Treasurys, rather than paying a repatriation tax to bring the cash back to American soil.

Last year, stock and bond returns tumbled after the Federal Reserve hiked interest rates at the fastest speed in 40 years. It was the first time in decades that both asset classes posted negative annual investment returns in tandem.
Over four decades, this has happened 2.4% of the time across any 12-month rolling period.
To look at how various stock and bond asset allocations have performed over history—and their broader correlations—the above graphic charts their best, worst, and average returns, using data from Vanguard.
How Has Asset Allocation Impacted Returns?
Based on data between 1926 and 2019, the table below looks at the spectrum of market returns of different asset allocations:
We can see that a portfolio made entirely of stocks returned 10.3% on average, the highest across all asset allocations. Of course, this came with wider return variance, hitting an annual low of -43% and a high of 54%.
A traditional 60/40 portfolio—which has lost its luster in recent years as low interest rates have led to lower bond returns—saw an average historical return of 8.8%. As interest rates have climbed in recent years, this may widen its appeal once again as bond returns may rise.
Meanwhile, a 100% bond portfolio averaged 5.3% in annual returns over the period. Bonds typically serve as a hedge against portfolio losses thanks to their typically negative historical correlation to stocks.
A Closer Look at Historical Correlations
To understand how 2022 was an outlier in terms of asset correlations we can look at the graphic below:
The last time stocks and bonds moved together in a negative direction was in 1969. At the time, inflation was accelerating and the Fed was hiking interest rates to cool rising costs. In fact, historically, when inflation surges, stocks and bonds have often moved in similar directions. Underscoring this divergence is real interest rate volatility. When real interest rates are a driving force in the market, as we have seen in the last year, it hurts both stock and bond returns. This is because higher interest rates can reduce the future cash flows of these investments. Adding another layer is the level of risk appetite among investors. When the economic outlook is uncertain and interest rate volatility is high, investors are more likely to take risk off their portfolios and demand higher returns for taking on higher risk. This can push down equity and bond prices. On the other hand, if the economic outlook is positive, investors may be willing to take on more risk, in turn potentially boosting equity prices.
Current Investment Returns in Context
Today, financial markets are seeing sharp swings as the ripple effects of higher interest rates are sinking in. For investors, historical data provides insight on long-term asset allocation trends. Over the last century, cycles of high interest rates have come and gone. Both equity and bond investment returns have been resilient for investors who stay the course.
