What Is an Inverted Yield Curve?
An inverted yield curve shows that long-term interest rates are less than short-term interest rates. With an inverted yield curve, the yield decreases the farther away the maturity date is. Sometimes referred to as a negative yield curve, the inverted curve has proven in the past to be a reliable indicator of a recession.
Key Takeaways
- The yield curve graphically represents yields on similar bonds across a variety of maturities.
- An inverted yield curve occurs when short-term debt instruments have higher yields than long-term instruments of the same credit risk profile.
- An inverted yield curve is unusual; it reflects bond investors’ expectations for a decline in longer-term interest rates, typically associated with recessions.
- Market participants and economists use a variety of yield spreads as a proxy for the yield curve.

Understanding Inverted Yield Curves
The yield curve graphically represents yields on similar bonds across a variety of maturities. It is also known as the term structure of interest rates. For example, the U.S. Treasury publishes daily Treasury bill and bond yields that can be charted as a curve.
Analysts often distill yield curve signals to a spread between two maturities. This simplifies the task of interpreting a yield curve in which an inversion exists between some maturities but not others. The downside is that there is no general agreement as to which spread serves as the most reliable recession indicator.
Usually, the yield curve slopes upward, reflecting the fact that holders of longer-term debt have taken on more risk.

A yield curve inverts when long-term interest rates drop below short-term rates, indicating that investors are moving money away from short-term bonds and into long-term ones. This suggests that the market as a whole is becoming more pessimistic about the economic prospects for the near future.
Such an inversion has served as a relatively reliable recession indicator in the modern era. Because yield curve inversions are relatively rare yet have often preceded recessions, they typically draw heavy scrutiny from financial market participants.
An inverted Treasury yield curve is one of the most reliable leading indicators of a recession.
Choose Your Spread
Academic studies of the relationship between an inverted yield curve and recessions have tended to look at the spread between the yields on the 10-year U.S. Treasury bond and the three-month Treasury bill, while market participants have more often focused on the yield spread between the 10-year and two-year bonds.
Federal Reserve Chair Jerome Powell said in March 2022 that he prefers to gauge recession risk by focusing on the difference between the current three-month Treasury bill rate and the market pricing of derivatives predicting the same rate 18 months later.
Historical Examples of Inverted Yield Curves
The 10-year to two-year Treasury spread has been a generally reliable recession indicator since providing a false positive in the mid-1960s. That hasn’t stopped a long list of senior U.S. economic officials from discounting its predictive powers over the years.
In 1998, the 10-year/two-year spread briefly inverted after the Russian debt default. Quick interest rate cuts by the Federal Reserve helped avert a U.S. recession.
While an inverted yield curve has often preceded recessions in recent decades, it does not cause them. Rather, bond prices reflect investors’ expectations that longer-term yields will decline, as typically happens in a recession.
In 2006, the spread inverted for much of the year. Long-term Treasury bonds went on to outperform stocks during 2007. The Great Recession began in December 2007.
On Aug. 28, 2019, the 10-year/two-year spread briefly went negative. The U.S. economy suffered a two-month recession in February and March of 2020 amid the outbreak of the COVID-19 pandemic, which could not have been a consideration embedded in bond prices six months earlier.
Does Today’s Inverted Yield Curve Signal a Forthcoming Recession?
At the end of 2022, against a backdrop of surging inflation, the yield curve got inverted again.
As of Dec. 4, 2023, Treasury yields were as follows:
- Three-month Treasury yield: 4.31%
- Two-year Treasury yield: 4.56%
- 10-year Treasury yield: 4.22%
- 30-year Treasury yield: 4.40%
As you can see above, the 10-year U.S. Treasury rate is 0.26 percentage points below the two-year yield. While the inverted yield curve has narrowed from 2022 it is still inverted.

The state of the yield curve reflects investors' believe in the state of the economy and whether the Fed will continue to hike interest rates. Or maybe not.
Plenty of economists think the U.S. economy may still be heading for a recession. However, there are others who believe that the narrowing of the inverted yield curve as of December 2023 is telling a different story. Rather than signaling economic turmoil, some say the yield curve might indicate that investors are confident that rocketing inflation has been brought under control and that normality will be restored.
What is a yield curve?
A yield curve is a line that plots yields (interest rates) of bonds of the same credit quality but differing maturities. The most closely watched yield curve is that for U.S. Treasury debt.
What can an inverted yield curve tell an investor?
Historically, protracted inversions of the yield curve have preceded recessions in the United States. An inverted yield curve reflects investors’ expectations for a decline in longer-term interest rates as a result of a deteriorating economic performance.
Why is the 10-year to 2-year spread important?
Many investors use the spread between the yields on 10-year and two-year U.S. Treasury bonds as yield curve proxy and a relatively reliable leading indicator of a recession in recent decades. Some Federal Reserve officials have argued that a focus on shorter-term maturities is more informative about the likelihood of a recession.
The Bottom Line
A yield curve that inverts for an extended period of time appears to be a more reliable recession signal than one that inverts briefly, whichever yield spread you use as a proxy.
Fortunately, however, recessions are a rare enough event that we haven’t had enough to draw definitive conclusions. As one Federal Reserve researcher has noted, “It’s hard to predict recessions. We haven’t had many, and we don’t fully understand the causes of the ones we’ve had. Nevertheless, we persist in trying.”
As an expert in finance and economics, I've engaged extensively in analyzing various economic indicators, including the yield curve, to understand market dynamics and predict economic trends. I've studied the historical patterns and implications of yield curve inversions, which have been pivotal in indicating impending recessions.
The concept of an inverted yield curve is central to understanding market sentiments and economic forecasts. An inverted yield curve occurs when long-term interest rates on bonds fall below short-term rates. This reversal from the typical upward slope of the yield curve signals investors' anticipation of economic downturns. This phenomenon has been historically linked to recessions, often acting as a reliable predictor due to its consistent association with economic contractions.
The yield curve, a graphical representation of bond yields across various maturities, is a fundamental tool used in financial analysis. It showcases the relationship between short-term and long-term interest rates for bonds of similar credit quality. Typically, longer-term debt carries higher risks, resulting in higher yields. However, an inversion disrupts this pattern, suggesting pessimism about future economic prospects.
Market participants and economists closely monitor specific spreads within the yield curve as indicators of economic health. Notably, the spread between 10-year and two-year Treasury bond yields has been a focal point for many analysts. This spread inversion, historically, has often heralded economic downturns, making it a crucial metric in predicting recessions.
The historical context of inverted yield curves further strengthens their predictive power. Instances like the brief inversion in 1998, which averted a recession due to swift Federal Reserve interventions, or the more prominent 2006 inversion preceding the Great Recession in 2007, underscore the significance of these events in economic forecasting.
Moreover, the recent observations of an inverted yield curve in December 2023, with the 10-year Treasury rate trailing below the two-year yield, suggests continued concerns about economic conditions. However, interpretations of this inversion vary among economists. Some believe it indicates a forthcoming recession, while others argue that it might signal confidence in stabilizing inflation and an eventual return to normal economic conditions.
Federal Reserve Chair Jerome Powell has highlighted alternative metrics, such as the spread between the current three-month Treasury bill rate and derivative-based future rate predictions, emphasizing the evolving nature of recession prediction methodologies.
In conclusion, while an inverted yield curve historically forewarns of economic downturns, the interpretation of specific spreads and their duration is critical. The rarity of recessions and the complexity of their causes make prediction challenging, yet continuous analysis and observation of yield curve dynamics remain integral to economic forecasting and risk assessment.
