The 30-Year Yield Signals Confidence, Not Fear
The yield on 30-year Treasury bonds surged above 5.30 percent on Monday, marking its highest point since 2007. It’s interesting—if you only read the economic news, you’d think this was a sign of trouble, but it actually reflects a recognition of the US economy’s robustness.
According to CNBC, this uptick was attributed to “growing concerns among investors about ongoing inflation and government borrowing.” You can find the theory of inflation anxiety almost everywhere. Historical comparisons popped up right away. Just last week, borrowing costs for 30-year bonds reached their highest since 2001, while yields in the secondary market peaked at a 19-year high on Monday.
However, this alarming view may not be entirely accurate; market movements don’t really suggest that investors are panicked over prolonged inflation or the government’s fiscal capabilities.
Breaking Down Yields
To understand nominal Treasury yields, they can typically be looked at as consisting of two main components. So, let’s simplify things. The first part is the compensation investors seek for expected inflation. This measure increases when concerns about debt, budget deficits, or the Federal Reserve’s credibility arise. The second part is the real return—essentially the compensation investors desire for not using their money in other investments or current consumption options. When investors anticipate that the economy will grow faster and expect other investments, especially stocks, to yield higher returns, they call for higher bond yields. A glance at the market for US Inflation-Protected Securities (TIPS) shows this clearly. As the principal of TIPS rises with the Consumer Price Index (CPI), the expected yield reflects the return above inflation that investors hope to gain.
The difference in yield between a conventional government bond and an inflation-protected bond of the same duration is known as the “break-even point inflation rate,” which indicates how much inflation compensation investors require.
If rising deficits and debt were troubling investors about the U.S. government inflating its obligations, then one would expect the 30-year break-even point to be on the rise. But that’s not quite what we’re seeing. The break-even point for July was 2.20%, down from 2.30% in May. Since this data series started in 2010, the median has been 2.23%. This figure is lower than the 2.55% seen in April 2022 and significantly below the 2.71% from 2011.
Looking at the daily numbers reveals even more. At the start of the year, the nominal 30-year Treasury yield was 4.86%, and the real yield on the inflation-protected 30-year Treasury was 2.63%. The gap was 2.23%. Given that the Fed’s 2% target references a measure called the Consumer Expenditure Price Index—which tends to be slightly lower than the CPI—it could imply that investors believe the Fed will keep to its target. By Friday, the nominal yield had jumped 39 basis points to 5.25%, while real yields climbed 37 basis points to 3%. The actual inflation compensation only increased by 2 basis points.
On Monday, even as yields hit that eye-catching 19-year high, the break-even point fell to 2.23%, a bit lower than the previous Friday. This indicates that much of the rise in long-term bond yields this year is genuine. Whatever shifts may have happened in market outlook, they’re not tied to anticipated long-term inflation rates.
Understanding the Bigger Picture
A more reasonable interpretation could be that expected real returns on other investments have increased. Investors seem to think the economy will provide more lucrative opportunities. Consequently, they seek higher returns on government bonds before committing their funds. In other words, rising yields on government bonds stem from an increasing opportunity cost as investors anticipate stronger growth ahead.
This misunderstanding often arises from the prevailing narrative—sometimes dubbed “Trump confusion syndrome”—that dominates economic reporting. When there’s a focus on factors like controlling illegal immigration or adjusting tariffs, it becomes challenging to interpret bond market signals accurately. If one believes that Fed Chairman Kevin Warsh is keen to restore credibility by being transparent, a rise in yields may seem like a spike in inflation expectations. If, however, one views Trump’s tax cuts and deregulation as unlikely to enhance growth, understanding the increasing opportunity cost of holding long-term bonds becomes difficult.
Yet, if you set aside such biases, the expectation for continued growth is clear. Investment in building artificial intelligence, for instance, is driving tremendous capital demand. Data centers, semiconductor plants, power generation, transmission equipment, and cooling systems all need financial backing. AI firms are issuing considerable amounts of corporate bonds, convinced that these investments will yield returns that outweigh the cost of borrowing. They also recognize that much of this growth must happen domestically, given the constraints on foreign AI influence within the US economy.
Increased real yields are precisely what you’d expect from an economy where capital productivity is on the upswing and businesses have discovered profitable new applications. Higher yields reflect the market’s demand to draw money from these investment opportunities back into Treasuries.
Long-term bonds aren’t a warning signal about runaway inflation. Instead, they’re point to something we need to pay attention to: the real return on capital is increasing. This shouldn’t be surprising in the context of a significant investment boom.
Sure, some people are concerned about long bonds, but oddly enough, the long bonds seem less anxious.
