On The Yield Curve Inversion: The Camel's Nose Is In The Tent - Maybe

  • Any inversion of a portion of the yield curve is a negative long leading indicator, specifically for the period 12 to 24 months out.
  • But the depth, duration, and breadth of the inversion are all important in assessing the weight to give the indicator.
  • A one-day inversion of a narrow band in the yield curve by no means inevitably means an ensuing recession.
  • In particular, actors with agency, and most importantly the Fed, can react to the indicator and alter course, thereby changing the trajectory of the future.


I am sure that there are dozens of posts up today in the economic and financial media about the yield curve inversion that happened yesterday. Just to document the atrocity, here is CNBC's yield chart from 5:30 PM ET, showing both an inversion at both the 3 to 5 year and 2 to 5 year timeframes:

A look at the history

Most of the commentary you have read probably boils down to an assertion that this is bad (it is) and that a recession is now likely in the next 12 to 24 months (maybe). But let's go to the graphs, and then step back a second for a little consideration.

First, here are the spreads between 2 and 5 year Treasuries (blue), 2 and 10 year Treasuries (red), and 3 month and 10 year Treasuries (green) going back the last 40 years:

Next, here is a close-up of 1998, which I'll discuss in more detail below:

Finally, here is the spread between the 10 and 30 year Treasuries over the same 40 year time frame:


So let's note a few things:

When the 2 to 5 year spread inverted, typically the 2 to 10 year spread did so simultaneously or very shortly, as in days or a week, later. Usually later, so did the 10 to 30 year spread. In fact, when all three of those levels were in inversion simultaneously, a recession always followed within 12 to 24 months. But, even if we just consider the 2 to 5 year spread, its inversion usually was a prelude to a full spread inversion of the yield curve.

In other words, as the saying goes, "the camel's nose is in the tent." If you're not familiar with the saying, it means that the rest of the camel is likely to soon follow, with bad consequences for the people in the tent.

BUT, consider the following:

1. Several times - at the end of 1994 and the beginning of 1998 -- an inversion only happened for one day or even only intraday. Not only did they not signal an oncoming recession but a reversal to a normal spread happened almost immediately. In other words, bond traders have agency, and as a whole (i.e., "the market") might decide that the move has gone on long enough.

2. The 10 to 30 year spread had a number of false positives. We don't have to worry about that for now.

3. More importantly, I would consider the second half of 1998 a false positive as well, since no recession began until nearly 3 years after the inversion started, and over two years after it ended. Specifically, in mid-1998, both the 2 to 5 year and 2 to 10 year spreads inverted. While the 2 to 5 year spread stayed inverted until the end of the year, the 2 to 10 year did not. By the time the 10 to 30 year spread inverted - sporadically, over one month near the end of the year -- the 2 to 10 year spread was already positive.

In short, a one-day inversion over a limited portion of the bond yield curve, while more often than not heralding a full-on inversion and bad consequences to come, is by no means dispositive.

Most significantly, as in 1998, the Fed might react. If you are aware of the history of an inversion, and if I am aware of the history of an inversion, and if all of the other commentators who are writing about it are aware of the history of an inversion (I lay 50/50 odds that by the time you read this, Paul Krugman has already weighed in), then don't you think the Fed and its economists might possibly discuss the possible implications of an inversion in their upcoming meeting? Particularly if Powell's boss, who can fire him "for cause," unleashes a Tweetstorm?

The Fed is an actor. The Fed has agency. The Fed can affect the future course of the bond market. The Fed can react to this news if it chooses, and thereby change the future.


If you've read me for any period of time, you know that I have been bullish on the economy since 2009. You also know that my array of long leading indicators has been deteriorating this year from positive, to weakly positive, to neutral 6 months ago, to negative for the last 3 weeks. Any sort of yield curve inversion just adds to the negativity.

But, to mix metaphors, the long leading indicators turning negative is like the Ghost of Christmas Future visiting Scrooge. Without more, they do not show what *must* be, only what will be if present trends continue, if actors with agency fail to find a correct course in time.

New Deal democrat As a professional who started an individual investor for almost 30 yeas ago, I quickly focused on economic cycles and the order in which they typically proceed. I have been writing about the economy for nearly 15 of those years, developing several alternate systems that include mid-cycle, long leading, short leading, coincident, lagging and long lagging indicators. I also focus particularly on their effects on average working and middle class Americans.
