When the rate of return on long-term United States sovereign debt is high, the market tends to think first about the Federal Reserve interest rate path. However, according to external sources,10 annual rates of return on United States debt do not only reflect short-term interest rate expectations in the future, but some of them come from investors.Term premiumThis is also why long-end interest rates sometimes continue to work in anticipation of lower interest rates.
The so-called term premium is the additional return required for holding long-term national debt in relative and repeated purchases of short-term national debt. The Federal Reserve in New York sees this as compensation for the risk of change in interest rates during the bond life. Since this indicator cannot be observed directly, model estimates are usually required.
Why is the term premium up?
Investors usually demand higher returns when the risk of long-term bonds is more difficult to judge or when the attractiveness declines. Unstable inflation prospects, a widening fiscal deficit and increased United States Treasury debt raise market demand for long-term bonds.
In addition to increased supply, increased interest rate volatility and reduced demand for long-term buyers, such as central banks and pensions, can push up long-term returns. The increase in global long-term debt supply, as well as changes in investor demand structure, were also mentioned in the United States Treasury Department ' s related resource materials as likely to put upward pressure on term premiums.
Equity valuation under pressure
According to the article, an increase in the term premium would directly suppress the stock market valuation in the absence of further moves by the Fed. This is due to the fact that when the rate of return on national debt rises, the market assesses the future profits of an enterprise with a higher discount rate, which is particularly sensitive to growth equity.
Another impact arises from competition for assets. If low-risk United States Treasury bonds provide higher returns, investors ' willingness to pay high valuations for high-risk assets will decline. Technology and AI are more affected, as the construction of chips, servers, electricity and data centres itself requires significant funding.
The encryption market will also be affected.
The article mentions that encrypted assets are also subject to pressure. Rising long-term rates of return usually mean tightening financial conditions, while increasing returns on low-risk assets, which may weaken some of the funds ' allocation needs for highly volatile assets.
For bond investors, it is more crucial to identify the sources of the rise in the rate of return. If the expected changes in the Federal Reserve dominate, inflation retreats or economic data weaken, it may be faster to drive the rate of return back; if the term premium rises, the long-end rate of return does not necessarily go down significantly, even if interest rates fall in the future.
Additional information:For example, the article states that in August 2026, the United States long-term national debt (LNG) rate of return rose significantly in August, with 30 annual rates of return rising by 5.2 per cent and 10 near 4.7 per cent, indicating that long-term interest rate changes have begun to pass on to risky assets such as equities.
