Summary of Key Points
Recently, there has been a frenzied selling of long-term U.S. government bonds (especially those with a 30-year maturity), causing yields to soar to nearly 20-year highs (with the 30-year yield breaking through 5.3%), triggering a chain reaction in global bond markets. The reasons behind this include the high U.S. fiscal deficit (nearly $2 trillion per year), the surge in corporate bond issuance driven by the AI boom, the Federal Reserve's hesitancy on inflation, and investors' concerns about long-term inflation and debt risks. This has not only increased the financing costs for the U.S. government but also affected areas such as mortgages and business loans. There are currently no signs of a market reversal, and institutions warn against attempting to buy bonds at these levels.
1. What does it mean when U.S. bond yields soar to nearly 20-year highs, with the 30-year yield breaking through 5.3%?
Simply put, bond yields and prices move in opposite directions: as yields rise, it indicates that fewer people are buying bonds, causing their prices to fall. The 30-year U.S. bond yield reaching 5.3% is the first time since 2007, meaning that investors would earn an annual interest rate of 5.3% on a $100 investment in these bonds—much higher than before—but this also reflects their fear of long-term risks.
For context, in 2007, the 30-year yield also reached 5.3%, but at that time, the U.S. government's debt was only $8.8 trillion; now it has exceeded $39.9 trillion, 4.5 times higher. With more debt and higher yields, the interest payments the government will have to make in the future are expected to increase dramatically.
2. Why are long-term U.S. bonds being sold so frenziedly?
Four main factors have come together:
1. The government is borrowing too much, leading to a surplus of supply over demand: The U.S. has a fiscal deficit of nearly $2 trillion per year (spending more than it earns by $2 trillion), and it can only cover this gap by issuing bonds. As more bonds are issued, investors cannot keep up with the demand, causing prices to fall and yields to rise. Last week, when the U.S. sold 30-year bonds, it had to offer an extremely high interest rate of 5.216% to sell them, the highest since 2001.
2. AI companies are competing for funds, diverting bond-buying capital: The AI boom has led large corporations to borrow heavily to fund infrastructure projects. This year, the issuance of corporate investment-grade bonds in the U.S. has repeatedly broken records (reaching over $145.2 billion in August, a new high for the same month). With limited investor funds, less money is available to buy government bonds.
3. The Federal Reserve's hesitation and market lack of confidence in inflation: Inflation has consistently been higher than the Fed's target of 2%, but the Fed has been slow to raise interest rates. Investors fear that inflation may remain high in the future, leading them to demand higher yields as a compensation for the risk of holding long-term bonds.
4. Global investors' concerns about long-term risks: Inflation has been high over the past five years, and with the U.S. debt on an out-of-control scale, there are fears that the country may not be able to repay its debts on time or that its currency could depreciate, prompting a widespread sell-off of long-term U.S. bonds.
3. The chain reaction of this selling spree:
- The U.S. government is suffering: Rising bond yields mean higher financing costs for the government, increasing its fiscal pressure and potentially leading to a vicious cycle of borrowing more to pay even higher interest rates.
- Higher mortgage and loan costs for individuals: U.S. bond yields serve as a benchmark for global interest rates, so mortgage rates (e.g., 30-year fixed-rate mortgages) rise accordingly. Currently, U.S. mortgage rates have exceeded 7%, making it difficult for many people to afford homes.
- Pressure on global bond markets: The yield on Canadian 30-year bonds has reached a 2010 high, and German long-term bond yields are at their highest since 2011. Bond markets in Europe and Japan have also declined because U.S. bonds were once considered a safe asset; now that they are unstable, other countries' bond markets are affected.
4. Institutions warn: Don't try to buy bonds at these levels yet! A reversal requires the following conditions:
Barclay Bank suggests that it is too early to buy long-term U.S. bonds, and improvement may only occur when several conditions are met simultaneously:
- A sudden reduction in the fiscal deficit (the government spends less money).
- A slowdown in the pace of AI company bond issuance.
- The U.S. Treasury reducing the issuance of long-term bonds (decreasing supply).
- Continuing economic deterioration (which could lead to the Fed lowering interest rates to ease pressure).
Castle Securities added that markets are very disappointed with the Fed's lack of decisive action on inflation, as high inflation has increased concerns about long-term inflation.
5. Is the rapid issuance of AI bonds “crowding out” government bonds?
In economics, there is a concept called the “crowding-out effect”: when the government borrows too much, it can reduce the financing options available for businesses, making it more expensive for them to borrow money. However, the current situation is reversed: the massive issuance of AI bonds has absorbed so much capital that investors no longer have enough funds to buy government bonds. For example, corporate bond issuance in August reached $145.2 billion, higher than in the same period of 2020, leading to reduced demand for government bonds and forcing yields to rise. This phenomenon, where businesses “crowd out” the government in borrowing, is relatively rare.
In summary, this sell-off of U.S. bonds is not isolated; it reflects a combination of issues such as U.S. debt, inflation, and the AI boom. For ordinary people, the most direct impact is higher mortgage and loan costs. For the global economy, instability in U.S. bonds leads to fluctuations in all assets. In the short term, this situation is likely to continue until the aforementioned conditions for a reversal are met.
