This article is about what is yield curve inversion. The yield curve is a graphical representation of the yields on similar bonds across a variety of maturities. For example, the U.S. Treasury publishes daily Treasury bill and bond yields that can be charted as a curve. The yield curve reflects the expectations of bond investors about the future course of interest rates, inflation and economic growth.
What is Yield Curve Inversion?
Normally, the yield curve slopes upward, meaning that longer-term bonds have higher yields than shorter-term bonds. This is because investors demand a higher return for locking up their money for a longer period of time, and because they anticipate higher inflation and interest rates in the future.
However, sometimes the yield curve inverts, meaning that longer-term bonds have lower yields than shorter-term bonds. This is an unusual situation that signals that investors are pessimistic about the economic outlook and expect lower inflation and interest rates in the future. An inverted yield curve also implies that investors are willing to accept lower returns for holding longer-term bonds, because they perceive them as safer assets than shorter-term bonds.
An inverted yield curve has historically been a reliable indicator of a recession. According to Investopedia, an inverted yield curve has preceded every U.S. recession since 1955. with only one false positive in 1966. The most commonly used measure of yield curve inversion is the spread between the 10-year and 2-year Treasury bond yields. When this spread turns negative, it means that the 10-year bond yield is lower than the 2-year bond yield, indicating an inverted yield curve.
The Federal Reserve Bank of St. Louis publishes this spread daily on its website. As of November 24. 2023. the spread was -0.45%, meaning that the 10-year bond yield was 0.45 percentage points lower than the 2-year bond yield. This is the most negative level since August 2022. when the spread briefly dipped below zero for the first time since 2007.
The World Economic Forum has created a visualization of the yield curve from November 2021 to November 2022 using eurodollar futures data, which are contracts that reflect the market expectations of future interest rates on U.S. dollar deposits. The visualization shows how the yield curve has become more inverted and more extreme over time, reaching levels not seen since the global financial crisis of 2008-2009.
Why does an Inverted Yield Curve Signal a Recession?
There are several possible explanations. One is that an inverted yield curve reflects a tight monetary policy by the central bank, which raises short-term interest rates to curb inflation and overheating in the economy. This reduces the demand for credit and investment, slowing down economic activity and growth.
Another explanation is that an inverted yield curve reflects a flight to quality by investors, who seek safer and more liquid assets such as long-term Treasury bonds in anticipation of a downturn in the economy. This increases the demand for long-term bonds and lowers their yields, while reducing the demand for riskier and less liquid assets such as stocks and corporate bonds, which lowers their prices and raises their yields.
A third explanation is that an inverted yield curve reflects a self-fulfilling prophecy by investors, who act on their expectations of a recession by reducing their spending and investment, which in turn causes a contraction in aggregate demand and output in the economy.
Regardless of the exact mechanism, an inverted yield curve is a worrisome sign for the economy and may prompt policymakers to take action to stimulate growth and prevent a recession. For example, the Federal Reserve may lower its target interest rate or implement quantitative easing to ease financial conditions and support lending and spending in the economy.
However, an inverted yield curve is not a perfect predictor of a recession, nor does it imply that a recession is imminent or inevitable. There may be other factors that affect the shape of the yield curve, such as changes in global demand and supply of bonds, fiscal policy actions by the government, or structural shifts in the economy. Moreover, there may be a lag between an inverted yield curve and a recession, which can vary from several months to several years.
Bottom Line
In this article, we have discussed what is yield curve inversion. While an inverted yield curve is an important signal to monitor, it should not be taken as a definitive or final verdict on the state of the economy.
