This week’s column is about interest rates and the yield curve, two key fundamentals for weighing future economic activity and market returns. As I was finalizing the column, however, Russia invaded Ukraine – an unfortunate but largely expected act of aggression. The war is unnecessary and will almost certainly lead to devastating outcomes for the Ukrainian people. But I do not believe this regional crisis is bearish for the global economy or markets.
Looking back at conflicts since 1925 – the Korean War, Vietnam, the Cuban Missile Crisis, the Iran/Iraq War, two U.S. wars in Iraq, the list goes on and on – it was only World War II that resulted in a bear market. Some readers may even recall that when Russia invaded and annexed Crimea in 2014, the S&P 500 continued to move higher, and did so for years:

At the end of the day, geopolitical crises are not desirable or positive for the world or markets. But they are also not necessarily a negative – historically speaking, it is the uncertainty that matters more and tends to weigh on markets. Now that Russia has invaded Ukraine, that uncertainty is gone, and markets can move on to discounting the effects on global growth, corporate earnings, inflation, interest rates, and the credit markets. Russia’s invasion may cause some disruption in oil markets and have knock-on effects on inflation, but I do not see material impact on any of the other economic fundamentals. Ukraine’s GDP makes up just 0.2% of the world’s total, and Russia and Ukraine combined make-up far less than 1% of total U.S. imports and exports.
Onto this week’s column.
There have been reports recently about the yield curve being in a flattening pattern, which many are saying could spell bad news for the economy. History supports the argument: an inverted yield curve has typically preceded recessions by about 5 to 15 months, and with the Federal Reserve on the cusp of a rate hike cycle, many investors are mumbling about a worsening economic outlook from here.2
The basis for these concerns happens when the yield curve is measured as the difference between the yield on the 10-year U.S. Treasury bond and the 2-year U.S. Treasury bond, as seen below. When the yield on the 10-year minus the yield on the 2-year is zero, the yield curve is completely flat. As you can see on the chart, the difference in yields is approaching zero – i.e., in a flattening pattern.

But there’s a problem with this analysis: comparing the 10-year U.S. Treasury bond yield with the 2-year is not the most accurate and meaningful way to measure the yield curve. In my view, it is much better to compare the 10-year U.S. Treasury bond yield with the 3-month U.S. Treasury bond yield – something many pundits and columnists are not doing when issuing warnings about the yield curve.
An analysis of the yield curve as the 10-year U.S. Treasury bond yield minus the 3-month U.S. Treasury bond yield shows the curve has steepened over the past year, not flattened (see chart below). The 10-year bond yield has been moving higher at a faster clip than the 3-month and other short-term rates, causing the steepening. Looking at the yield curve in this way (the correct way, in my view) changes the economic narrative completely and signals that the financial conditions have been getting better recently, not worse.

Some investors may be wondering, why does any of this yield curve analysis matter? For two reasons, in my view. The first is that the yield curve gives us insight into bank profitability, which is correlated with economic activity. The second is that historically, the yield curve has been a reliable predictor of economic recessions, so it is worth keeping an eye on.
Let’s start with the first reason regarding bank profitability. Put simply, banks borrow money and pay deposits using short-term interest rates (overnight and up to 3 months), and then in turn loan money to consumers, homeowners, and businesses at longer-term interest rates (10+ years). This is the key reason investors should look at the 10-year and 3-month U.S. Treasury yields for the yield curve, as these are the rates that matter. Banks generally do not borrow money at 2-year U.S. Treasury rates.
Banks make money when long-term interest rates are meaningfully higher than short-term interest rates – a steep yield curve. When short-term interest rates are higher than long-term interest rates and the yield curve inverts, net interest margins get squeezed, profits fall, and a bank’s incentive to lend money falls. As banks loan less, economic activity tends to follow.
The second reason yield curve analysis is important is that historically, an inverted yield curve has been a good indicator of an economic slowdown ahead. Readers can see in the chart below that when the yield curve inverts (the line dips below zero), recessions tend to follow shortly after. Since 1970, there have been eight recessions and all of themwere preceded by an inverted yield curve.

The upshot in the current environment is easy to see in the chart – the line is not only above zero, but it is also rising. That means the yield curve has been steepening recently, which is counter to what is being said and written about in the financial media.
Bottom Line for Investors
The yield curve is an important economic indicator and should be monitored regularly. It matters to bank profitability, which in turn matters to loan growth and economic activity. But the yield curve is also analyzed incorrectly quite often, in my view. Looking at the 10-year U.S. Treasury bond yield minus the 2-year U.S. Treasury bond yield does not provide a meaningful reading – banks do not borrow at 2-year rates.
Instead, investors should always focus on the 10-year U.S. Treasury bond yield (or longer) minus the 2- or 3-month U.S. Treasury bond yield. In the current environment, this more accurate view shows the yield curve has been steepening, not flattening, which should bode well for the economic activity ahead.
