Yield Curve
Graph of interest rates across different maturities for similar credit quality bonds, typically U.S. Treasuries.
The yield curve is a graphical representation of interest rates (yields) on bonds of the same credit quality (typically U.S. Treasury securities) across different maturities—from overnight to 30 years. It visualizes the term structure of interest rates, revealing the market's expectations for future interest rates, economic growth, and inflation at different time horizons.
Three shapes characterize yield curves. A normal (upward-sloping) curve exists when long-term yields are higher than short-term yields—investors demand higher returns for lending money longer because of greater uncertainty, inflation risk, and opportunity cost. A flat curve means short and long-term yields are approximately equal, often signaling an economic transition. An inverted curve (downward-sloping) occurs when short-term yields exceed long-term yields—historically a reliable predictor of recession, as the Federal Reserve has raised short-term rates so aggressively that investors expect future rate cuts and lower growth.
Yield curve dynamics matter enormously in finance. Bank profitability depends on the slope—banks borrow short-term and lend long-term, so a steeper curve increases their net interest margin while an inverted curve can compress profitability. Pension funds and insurance companies model liability durations against yield curve movements. Bond portfolio managers execute 'steepener' or 'flattener' trades to profit from curve shape changes.
For corporate finance, the yield curve establishes risk-free discount rates for DCF valuations—longer-duration assets use the appropriate Treasury yield for their cash flow timing. Companies issuing long-term debt watch the long end of the curve, while working capital borrowers (revolvers, commercial paper) watch the short end.
The most widely monitored yield curve relationship is the spread between the 2-year and 10-year Treasury yields (the 2s10s spread), which inverted in 2022 and remained negative for an extended period before economic conditions shifted.
FAQs
Why does an inverted yield curve predict recessions?
An inverted yield curve predicts recessions because it signals that the Federal Reserve has tightened monetary policy so aggressively (raising short-term rates) that markets expect future rate cuts as economic growth slows. It also directly tightens credit conditions—banks borrow short-term and lend long-term; when short rates exceed long rates, lending becomes unprofitable, reducing credit availability and slowing economic activity. The 2s10s spread has inverted before every U.S. recession since the 1970s, though the lead time varies from 6 months to 2 years, making it a directional signal rather than a precise timing tool.
How do changes in the yield curve affect stock valuations?
Rising long-term interest rates increase discount rates used in equity valuation models (DCF), reducing the present value of future cash flows and compressing price-to-earnings multiples. High-growth, long-duration stocks (technology companies with earnings far in the future) are most sensitive because a larger proportion of their value comes from distant cash flows that are more heavily discounted. Short-duration value stocks (with earnings heavily weighted near-term) are less affected. Rising rates also increase the relative attractiveness of bonds, drawing capital from equities. This explains why growth stocks declined significantly during the 2022–2023 rate hiking cycle.
What is duration in the context of the yield curve?
Duration measures a bond's price sensitivity to interest rate changes—specifically, the percentage price change for a 1% change in interest rates. A bond with 7-year duration loses approximately 7% of value if interest rates rise by 1%. Longer maturity bonds generally have higher duration (more price sensitivity) because more of their cash flows are distant, subject to higher discounting. When the yield curve steepens (long rates rise relative to short), long-duration bonds lose more value than short-duration bonds. Portfolio managers use duration to manage interest rate risk and to position for expected yield curve movements.
