introduction
U.S. Treasury bonds, known as the "safe haven" of the global financial market, are essentially "IOUs" issued by the U.S. government when borrowing money from investors. These IOUs promise to repay the principal on a specific date and pay interest at an agreed rate. However, when countries or institutions holding Treasury bonds choose to sell them for various reasons, it will trigger a series of market reactions, which will in turn affect the U.S. and even the global economy.
This article will take Japan's holdings of $1.2 trillion in U.S. Treasuries as an example to analyze the price drops and yield increases caused by the sale of Treasuries, as well as the far-reaching impact on U.S. finances, revealing the logic and risks behind this financial phenomenon.
1. The Nature and Market Mechanism of U.S. Treasury Bonds
U.S. Treasury bonds are debt instruments issued by the U.S. Treasury to cover fiscal deficits or support government spending. Each bond clearly indicates the face value, maturity date, and interest rate. For example, a bond with a face value of $100, an annual interest rate of 3%, and maturity in one year means that the holder will receive $100 in principal plus $3 in interest, a total of $103. This low-risk feature makes U.S. Treasury bonds a favorite of investors around the world, especially countries such as Japan, which hold up to $1.2 trillion.
However, treasury bonds do not have to be held until maturity. Investors can sell them in the secondary market for cash. The trading price of treasury bonds is affected by market supply and demand: when demand is strong, prices rise; when supply is excessive, prices fall. Price fluctuations directly affect the yield of treasury bonds and constitute the core of market dynamics.
2. Hypothetical scenario of Japan selling government bonds
Suppose Japan decides to sell some of its US Treasury bonds due to economic needs (such as stimulating domestic consumption or coping with exchange rate pressure), and pushes a large number of "IOUs" out of the $1.2 trillion into the market. According to the principle of supply and demand, the supply of Treasury bonds in the market suddenly increases, and investors' bids for each Treasury bond will decrease. For example, a Treasury bond with a face value of $100 may only be sold for $90.
This price drop will significantly change the yield of the Treasury bond. Continuing with the example of a Treasury bond with a par value of $100, an annual interest rate of 3%, and a principal and interest payment of $103 after one year:
Normal situation: The investor pays $100 to purchase and receives $103 at maturity, with a yield of 3% ($3 interest ÷ $100 principal).
After selling: If the market price drops to $90, the investor buys at $90 and still gets $103 upon maturity, with a profit of $13, and the yield rises to 14.4% ($13 ÷ $90).
As a result, the sell-off caused Treasury prices to fall and yields to rise, a phenomenon known in financial markets as the "inverse relationship between bond prices and yields."
3. The direct consequences of rising yields
The impact of rising U.S. Treasury yields on the market and the economy is multi-dimensional. First, it reflects changes in market confidence in U.S. Treasuries. Rising yields mean that investors require higher returns to offset risks, which may be due to excessive selling or increased market concerns about the health of the U.S. fiscal system.
More importantly, rising yields directly push up the cost of newly issued treasury bonds. The U.S. government's debt management strategy is often called "debt repayment" - raising funds by issuing new treasury bonds to repay old treasury bonds that have matured. If the market yield remains at 3%, new treasury bonds can continue to use similar interest rates. But when the market yield soars to 14.4%, new treasury bonds must offer higher interest rates to attract investors, otherwise no one will be interested.
For example, suppose the United States needs to issue $100 billion in new Treasury bonds:
- At 3% yield: Annual interest expense is $3 billion.
- At a yield of 14.4%: Annual interest expense increases to $14.4 billion.
This difference means an increased fiscal burden on the US, especially considering that the current US debt is over $33 trillion (as of 2023 data, and may be higher in 2025). The surge in interest payments will squeeze out other budgets, such as infrastructure, health or education.
4. Financial difficulties and the risk of “taking money from Peter to pay Paul”
The U.S. government's debt cycle relies on low-cost financing. When yields rise, interest rates on new debts rise, and fiscal pressure increases sharply. Historically, the United States has maintained debt sustainability by "taking money from Peter to pay Paul" - borrowing new debt to repay old debts. However, in a high-interest environment, the cost of this strategy has rapidly expanded.
Taking the Japanese sell-off as a trigger, assuming that market yields remain high, the United States may face the following dilemma:
- Debt snowball effect: High interest rates lead to an increase in the proportion of interest expenditures in the fiscal budget. According to the Congressional Budget Office (CBO), if interest rates continue to rise, interest expenditures may account for more than 20% of the federal budget by 2030. This will limit the government's flexibility in economic stimulus or crisis response.
- Shaken market confidence: As a global reserve asset, abnormal fluctuations in the yield of U.S. Treasuries may cause investors to worry about the U.S. credit rating. Although the U.S. has maintained its AAA rating to date, S&P downgraded its rating to AA+ in 2011. Large-scale selling may exacerbate similar risks.
- Monetary policy pressure: Rising U.S. Treasury yields may force the Federal Reserve to adjust monetary policy, such as raising the federal funds rate to curb inflation expectations. This will further push up borrowing costs, affecting businesses and consumers.
5. Impact of the global economy
Japan's selling of U.S. debt is not only a problem for the United States, but will also affect global financial markets:
- Dollar exchange rate fluctuations: Rising U.S. bond yields may push up demand for the U.S. dollar, leading to its appreciation. This is unfavorable for export-oriented economies such as Japan, which may prompt them to further sell U.S. bonds, forming a vicious cycle.
- Emerging market pressure: Many emerging markets have debts denominated in US dollars. The appreciation of the US dollar and high interest rates will increase their debt repayment costs and may trigger a debt crisis.
- Global asset reallocation: The decline in U.S. Treasury prices may prompt investors to reallocate assets to other safe assets (such as gold) or high-risk assets (such as stocks), triggering market volatility.
6. How to deal with the risk of sell-off?
To mitigate the crisis caused by the sell-off, the U.S. and global financial systems need to take multiple measures:
- U.S. fiscal reform: By optimizing taxes or cutting spending, reducing reliance on debt financing and enhancing market confidence in U.S. debt.
- International coordination: Major creditor countries (such as Japan and China) and the United States can negotiate through bilateral negotiations to gradually reduce their holdings of U.S. debt and avoid drastic market fluctuations.
- Federal Reserve intervention: In extreme cases, the Federal Reserve may purchase U.S. Treasuries through quantitative easing (QE) to stabilize prices and yields, but this may increase inflation risks.
- Diversified reserves: Global central banks can gradually diversify their foreign exchange reserves, reduce their reliance on U.S. Treasuries, and spread the risks of a single asset.
Conclusion
U.S. Treasuries are not only the government's "IOUs," but also the cornerstone of the global financial system. The hypothetical scenario of Japan selling $1.2 trillion in U.S. Treasuries reveals the delicate and complex balance in the Treasury market: selling leads to falling prices and rising yields, which in turn pushes up U.S. fiscal costs and may even destabilize the global economy. This chain reaction reminds us that a single country's debt decisions can have far-reaching global consequences. In the current context of high debt and high interest rates, countries need to manage financial assets prudently and jointly maintain market stability to prevent the debt game of "taking money from Peter to pay Paul" from evolving into an unmanageable fiscal dilemma.
