The Retired Investor: Could higher bond yields simply reflect a stronger economy?

PITTSFIELD, Mass. — Over the last month, equity investors have grown concerned with the rapid rise in U.S. Treasury bond yields.

Higher interest rates should spell danger for stocks. And yet, equities are still less than 2 percent from all-time highs. What gives?

Many financial experts say bond yields are rising because of oil prices, inflation, out-of-control government spending, Trump tariffs, and anticipation of Fed rate hikes. What if the explanation was much simpler? Could higher bond yields simply reflect a stronger growth economy?

This isn’t a new concept. The higher growth/yield correlation occurred in 1994, 2009, and 2012. In fact, financial history is rife with similar correlations. The underlying dynamics are straightforward. When the economy grows more rapidly than expected, consumer spending and business investment increase, as does the stock market. That’s a good thing if it doesn’t contribute to higher inflation.

To prevent the economy from overheating and triggering more inflation, central banks often raise interest rates to make borrowing more expensive. As readers know, the U.S. Federal Reserve Bank has begun an interest rate tightening cycle at its September meeting. The odds that they will tighten again in October have come down. It is perfectly natural for bond yields to rise in anticipation of a hiking cycle.

That is exactly what at least one eminent Fed president sees in this recent climb in bond yields. I caught a CNBC interview with New York Fed President John Williams, a permanent voting member of the rate-setting Federal Open Market Committee, last Wednesday. He remains in the wait-and-see camp among Fed Heads, while others are clamoring for more hikes.

On Tuesday, in prepared remarks, he said, "With the policy action we took at our September meeting, there is no need for urgency, and we have time to gather more information."

Williams is one of those Fed figures I pay attention to because he has a great deal of experience in the financial markets and keeps his cool when others don’t. When asked about yields, he said, "What’s driving it, in large part, is a really strong economy and a strong economic outlook fueled by big investments in AI and data centers and technology in general."

Williams laid out his base case for interest rates when he said: "If the economy evolves in a manner broadly consistent with my forecast, one further upward adjustment of the federal funds target range may be appropriate late this year to support a timelier return of inflation to target."

One way to see whether inflation or growth is driving the climb in bond yields is to determine which has moved more: real yields (nominal rates minus the inflation rate) or inflation expectations. Real yields reflect the market’s expectations of the economy's underlying strength. It is usually measured by looking at the rates on U.S. inflation-protected U.S. Treasuries called TIPS.

To see how much of a yield move is driven by inflation expectations, you measure the difference between TIPS yields and those of regular Treasury securities maturing around the same time. The gap between the two should give us an idea of what investors think the inflation rate will be during that time.

Axios Markets, a well-respected financial newsletter, crunched the numbers and discovered that over the last month the five-year real yield accounted for 0.72 percentage points in the rise in the five-year Treasury note. Inflation expectations only accounted for 0.06 percentage points of the move. Some may find that hard to believe.

Yes, I'm aware of all the consternation around the economy's inflation, but there are compelling reasons to believe the yield spike is a growth story. Second-quarter Gross Domestic Product was revised up to a 2.2 percent annualized growth rate from the previously reported 1.5 percent.

Consumer spending grew at a healthy 3.8 percent annualized pace, while stronger business investment contributed to the revision. Consider that the artificial intelligence revolution has sparked the largest capital investment boom in American history. Goldman Sachs analysts project AI spending will reach $1.3 trillion in 2027 and $2 trillion in 2028, in addition to the trillions of dollars already spent. As a result, corporate profits have grown between 20 percent and almost 30 percent per quarter for the last few quarters. The unemployment rate is at 60-year lows. That is a heck of a case for the growth/yield story.

Granted. For the ordinary worker, struggling with mounting energy bills, affordability issues, and the like, it certainly doesn’t feel like growth. In fact, American laborers are receiving the smallest share of income from these economic benefits in our nation's history. Of course, every two years, these same workers can change that equation if they so choose through the ballot box. Recently, they have chosen not to.
