The Flattening of the Yield Curve
Why are investors and economists getting nervous about Treasury yields?
One of my responsibilities as your financial adviser is to not only recommend suitable investments for your portfolio, but to also help you manage the risk of your portfolio. I accomplish this by monitoring several economic indicators that help paint a picture of where we are in the business cycle. One indicator that is in greater focus these days among economists and the financial community is the yield curve.
What is the yield curve, and why is the financial media writing about it? Here is a brief explanation, starting with a clarification.
A yield curve is really an X-Y graph projecting expected rates of return for equivalent-quality bonds with different maturity dates. But it is not just any yield curve that matters. When investors, commentators, and economists talk about “the yield curve,” they are talking about the graph plotting the interest rates of Treasuries: 3-month, 2-year, 5-year, 10-year, and 30-year notes. The “curve” is the line connecting their projected future yields. This Treasury yields snapshot is authoritatively referred to as: “the yield curve.”1,2
The yield curve normally slopes upward. (Think “rise over run.”) In other words, the projected yields on the short-term Treasuries (at the left of the X-Y graph) are small compared to the projected returns on the 10-year and 30-year Treasuries.2
When the economy is booming, the slope of the yield curve is often steep. A thriving economy typically has significant inflation, and when investors see rising inflation, they assume the Federal Reserve will start raising interest rates. That belief leaves them cold on longer-term bonds, so the prices of those bonds begin to fall, and their yields correspondingly rise.2
The yield curve usually flattens when the Fed tightens. It has been flattening lately, and some economists wonder if it will invert. When the yield curve inverts, interest rates on short-term Treasuries exceed interest rates on longer-term Treasuries.2,3
Inverted yield curves are strongly correlated with recessions. In fact, every recession America has experienced in the last 50 years has been preceded by an inverted yield curve. Three times in the 1950s, however, an inverted yield curve failed to presage a downturn.2,3
Right now, the gap between the 10-year and the 2-year Treasury is being closely watched. It has been steadily declining since December 2015 (when the Fed began tightening), and it narrowed to less than 0.5% this spring.2 Looking back over the last half-century, the 10s-2s gap has slimmed to less than 0.5% five other times, with an inversion of the yield curve – and a recession – following each time. Those recessions took time to arrive, though. On average, they began nearly two years after the yield curve inverted.2
Is a flatter yield curve a new normal, as former Fed chair Janet Yellen argued in 2017? She felt the latest gradual flattening was actually a product of a changing relationship between the yield curve and the business cycle. If that is correct, investors could worry a little less about the Fed’s determination to maintain its pace of rate hikes. (Its latest dot-plot projects four interest rate increases in 2018.) The New York Fed recently put the chance of a 2019 recession based on the slope of the yield curve at 11%; in comparison, the chance was 40% on the eve of the Great Recession.3,5
Regardless of whether the yield curve flattens or steepens, I will continue to keep an eye on this indicator - as well as other economic factors that help provide a glimpse of where we are in the economic cycle. We'll make portfolio recommendations and adjustments as necessary.
