As I noted earlier this week, I haven’t updated my suite of long leading indicators in awhile, mainly because they have been overwhelmed by the economic chaos emanating from Washington, and partly also because several important ones are in terra incognito. On Monday and Wednesday I updated the non-financial elements of the long leading indicators having to do with housing and consumer spending. Today let me focus on one of the financial elements, that has been most puzzling: interest rates.
The interest rate elements of the long leading indicators come in two varieties: the *level* of rates, and the *duration spread* of rates. If we start from the idea that interest rates are “the cost of renting money,” then the former simply means that renting money at a lower rate of interest is always better than renting it at a higher rate of interest. The latter means that normally we would expect to pay a higher rate of interest the more we risk dealing with unforeseen issues further out into the future. If the immediate future is deemed more risky, something is wrong.
The level of rates has typically been measured by corporate bond yields, and there are systems that rely on such rates going back 100 years. In fact we can take the relationship all the way back to the 1850s if we measure by short term corporate paper. So let me start by directing your attention to the red line in the two below graphs, which shows the interest rate on BAA rated corporate bonds, historically from the 1980s through the present:
While it is absolutely true to say that not every significant increase in corporate bond yields presaged a recession, it is true that all recessions (except for the brief pandemic lockdown) were presaged by an increase in those rates.
Now let me explain the blue line. It is a similar measure, but for Treasurys, using the average of 3 month, 2 year, 5 year, and 10 year notes, which captures short, medium, and longer term rates. Like corporate bonds, there were significant increases in the average Treasury interest rates before each recession - although note the sharp increases in 1994-95 did not presage a recession.
Now let’s focus on the last few years of the same data:
After the very sharp interest rates increases of 2022 into 2023 - which did not presage a recession (at least not in the ensuing 3 years!), both corporates and Treasurys have meandered within relatively narrow ranges — the former between 5.4% and 6.4%, and the latter between 3.6% and 4.6%. Corporate bonds are currently almost right in the middle of that range, while Treasury rates at the short end have contributed to a downtrend in those rates which has not really been broken by the increase that started with the onset of the Iran war.
In short, the *level* of bond rates is not sending a negative signal at this time, but rather “neutral.”
Now let’s turn to the duration spread or yield curve measure.
Here is the historical graph from the 1980s until the pandemic of the 10 year (blue), 2 year (gold), and 3 month (red) Treasurys, together with the Fed funds rate (purple):
In general, throughout most of these economic expansions, the longer the duration of the government note, the higher the interest rate it commanded. Further, not every significant increase in the Fed funds rate (1984, 1994) gave rise to an inversion. But in 1989, 2000, and 2006 there were across the board inversions, where in response to the Fed hiking rates, the shorter the duration of the note, the higher the interest rate was demanded. And sure enough, recessions followed. Further, those recessions ended about 4 to 8 months after rates were fully normalized.
Now let’s turn to the post-pandemic record:
We had a nearly full inversion of the curve in 2023-24, with only the 3 month note paying slightly more than the Fed funds rate. Both widespread models for recession forecasting, featuring the 10 year minus 2 year, and 10 year minus 3 month spreads signaled “recession ahead.”
But the curve started normalizing in late 2024 (as to the 10 year minus 2 year spread), and then in 2025 (as to the 10 year minus 3 month spread). The normalization was completed earlier this year when both the 2 year and 3 month spread turned higher than the Fed funds rate.
Based on past experience, that is a positive signal for roughly year end 2026 and beyond.
But there is one wrinkle, because as I pointed out about a month ago, this is the first time in history that a yield curve has normalized by Treasury note rates moving *higher*, rather than following a decline in the Fed funds rate *lower.* This is terra incognito.
There is one somewhat similar episode from the past which ought to indicate caution is still very much warranted. Here is the smae graph focusing in on the Great Recession:
Note that the yeild curve started to normalize in late 2007, and was almost completely normalized (with only the Fed funds vs. 3 month spread remaining inverted) by spring 2008. Further - and very similarly to right now - part of that normalization was the increase in interest rates in the 3 months and 2 year notes. And then the investment banks imploded.
Just like now, in spring 2008 there was a gas price spike, from roughly $3 to $4.25/gallon:
It was this inflationary pulse which caused interest rates to increase. That finally broke the proverbial camel’s back.
While the current gas price spike is not as severe either in terms of GDP or average wages as the one in 2008, there is nevertheless an inflationary pulse in the economy. So while the duration spread indicator is positive, the uniqueness of its regularization warrants a big fat asterisk.
