Yield Curve Plotter

The yield curve can take three primary shapes, each signaling a different economic outlook:

Normal (upward-sloping) curve:

• Longer maturities yield more than shorter ones — the natural state of affairs
• Investors demand a term premium for locking up money longer, compensating for inflation risk and uncertainty
• Signals healthy economic growth expectations and stable or accommodative monetary policy
• Historically, a 2s/10s spread above 50 basis points is considered solidly normal

Flat curve:

• Short-term and long-term yields are nearly the same, with minimal term premium
• Often occurs during transition periods — either the Fed is tightening (pushing short rates up) or the economy is weakening (pulling long rates down)
• Banks earn less from the borrow-short/lend-long trade, which can tighten credit conditions
• A flat curve is ambiguous — it can precede either a return to normal or a move into inversion

Inverted (downward-sloping) curve:

• Short-term yields exceed long-term yields — the bond market is signaling that it expects the Fed to cut rates in the future
• Rate cuts typically happen because the economy is weakening, which is why inversion is such a powerful recession signal
• The 2s/10s and 3M/10Y are the two most-watched spread measures. Both have strong recession-prediction track records
• Important: the recession typically begins 6 to 24 months after initial inversion, and often not until the curve un-inverts (steepens again)

The 2s/10s spread is the difference between the 10-year Treasury yield and the 2-year Treasury yield. It is the most widely cited measure of the yield curve's slope and is tracked by the Federal Reserve, Wall Street banks, and financial media alike.

How to calculate it:

2s/10s Spread = 10-Year Yield − 2-Year Yield

A positive spread means the curve is upward-sloping (normal). A negative spread means the curve is inverted. The larger the absolute value, the more pronounced the signal.

Why 2s/10s specifically?

• The 2-year yield closely tracks where the market expects the Fed Funds rate to be over the next two years. It captures near-term monetary policy expectations.
• The 10-year yield reflects long-run growth and inflation expectations, plus term premium. It is also the benchmark rate for mortgages, corporate bonds, and DCF discount rates.
• Together, they capture the tension between where the Fed is now (or headed) and where the market thinks the economy will be in the long run.

Historical context: The 2s/10s spread inverted before every U.S. recession going back to the late 1970s. The median lead time from first inversion to recession onset is roughly 14 months. However, false positives are rare but not impossible — in some cases, the curve briefly touched zero without a recession following.

The alternative measure — the 3M/10Y spread — is preferred by some economists (including Fed researchers) because the 3-month T-bill more directly reflects the current Fed Funds rate. Both are useful; they occasionally diverge, providing additional information.

An inverted yield curve predicts recessions because it reflects the bond market's expectation that short-term interest rates will fall significantly in the future. The only reason the Fed cuts rates aggressively is economic weakness. So inversion is the market pricing in a downturn before it arrives.

The mechanism in more detail:

• Expectations theory — Long-term yields approximate the average of expected future short-term rates. If investors expect rates to fall (because the Fed will be cutting), the long end of the curve drops below the short end.
• Credit channel — When short rates exceed long rates, banks' net interest margins get squeezed. Lending becomes less profitable, so banks tighten credit standards. Less credit means less economic activity.
• Self-fulfilling dynamics — When businesses and consumers see the inversion and hear recession talk, they may pull back on spending and hiring preemptively, contributing to the slowdown the curve was predicting.

The track record: The 2s/10s has inverted before all six of the last six U.S. recessions (1980, 1981, 1990, 2001, 2007, 2020). The 3M/10Y spread has a similarly impressive record. The average lead time is 12 to 18 months, though it has been as short as 6 months and as long as 24.

Important caveats: Inversion is not a timing tool. Markets can stay inverted for months while the economy continues to grow. The recession often begins after the curve un-inverts — that is, when the Fed starts cutting rates (re-steepening the curve), confirming that the slowdown has arrived. Selling everything at first inversion and sitting in cash for 18 months has historically been a poor strategy.

Term premium is the extra yield investors demand for holding a longer-maturity bond instead of rolling over a series of shorter-term bonds. It compensates for the uncertainty and risks of being locked into a fixed rate for an extended period.

Sources of term premium:

• Inflation uncertainty — Over 10 or 30 years, inflation could erode a bond's purchasing power far more than over 3 months. Investors demand compensation for this risk.
• Interest rate risk — Longer-duration bonds have higher price sensitivity to rate changes. A small rise in yields causes a much larger price drop on a 30-year bond than a 2-year bond.
• Liquidity and supply/demand — Changes in government borrowing patterns, central bank bond purchases (quantitative easing), or shifts in foreign demand can compress or expand term premium independently of economic expectations.

Why it matters for the yield curve: Under pure expectations theory, the yield curve's slope depends only on expected future short rates. In reality, term premium adds an upward bias to the long end. When term premium is positive and large, the curve appears steeper than economic expectations alone would warrant. When term premium is compressed (as it was during years of quantitative easing), the curve can flatten or invert even without strongly bearish economic expectations.

This is why some economists argue that the post-2022 inversion may have been partially driven by distorted term premiums rather than pure recession expectations. The New York Fed publishes an estimated term premium decomposition (the ACM model) that attempts to separate expectations from term premium in the 10-year yield.

The Federal Funds rate is the overnight lending rate between banks, set as a target range by the Federal Reserve. It is the shortest interest rate in the economy and serves as the anchor for the entire yield curve.

The transmission mechanism:

• Short-term Treasuries (1M, 3M, 6M) trade very close to the Fed Funds rate. When the Fed hikes, these yields move up almost immediately.
• Medium-term Treasuries (2Y, 5Y) reflect the average of expected Fed Funds rates over the next several years. If the market expects the Fed to cut, the 2Y will trade below the current Fed Funds rate.
• Long-term Treasuries (10Y, 30Y) are less sensitive to near-term Fed actions. They reflect long-run economic growth potential, inflation expectations, and term premium.

How the Fed causes yield curve shifts:

• Tightening cycle (raising rates) — Pushes the short end up. If long rates do not rise as much, the curve flattens. If the market expects the tightening to slow growth, long rates may actually fall, causing inversion.
• Easing cycle (cutting rates) — Pulls the short end down, typically steepening the curve. The long end may not fall as much if the market expects the easing to eventually revive growth and inflation.
• Quantitative easing/tightening — Direct bond purchases compress long-term yields and term premium (QE flattens the curve). Selling or allowing bonds to roll off (QT) does the opposite.

The critical takeaway for equity investors: the risk-free rate used in CAPM and WACC typically references the 10-year Treasury, not the Fed Funds rate. But the Fed Funds rate indirectly influences the 10-year yield through expectations, making Fed policy the single biggest driver of discount rates across all asset classes.

The yield curve is a valuable input but should never be the sole driver of investment decisions. Here is how different types of investors can incorporate it:

For equity investors:

• Use the 10-year yield as the risk-free rate in CAPM and WACC calculations for DCF models. When the 10Y rises, all else equal, fair values decline.
• Monitor curve steepening for bank stocks and flattening/ inversion for defensive sectors. Rate-sensitive sectors like utilities and real estate react strongly to shifts in long rates.
• Do not panic-sell based on inversion alone. Historically, equities have often rallied for months after initial inversion. The signal is about what happens 12 to 18 months from now, not tomorrow.

For fixed-income investors:

• A steep curve rewards extending duration — you earn meaningful extra yield for going longer.
• A flat curve means there is little compensation for duration risk. Consider staying shorter and waiting for steepening.
• An inverted curve paradoxically means short-term bonds pay more than long-term ones. T-bills and money market funds may offer higher yields than 10-year bonds.

For business and real estate decisions:

• The curve influences mortgage rates (pegged to the 10Y), corporate borrowing costs, and the cost of floating-rate debt. A steep curve means fixed-rate borrowing is more expensive relative to floating.
• Inversion can signal a coming credit tightening, as banks reduce lending when margins shrink. Companies with upcoming refinancing needs should pay attention.

Both the 2s/10s (10-year minus 2-year) and the 3M/10Y (10-year minus 3-month) are widely used measures of the yield curve's slope. They usually move in the same direction but can diverge, and each has strengths:

2s/10s spread:

• The most commonly cited spread on financial news and trading desks
• The 2-year yield incorporates market expectations for Fed policy over the next 1–2 years, providing a forward-looking view
• Tends to lead the cycle — it can invert before the Fed is done hiking because the 2Y anticipates the rate path
• Has preceded all six of the last six U.S. recessions

3M/10Y spread:

• Preferred by many academic economists and the Federal Reserve Bank of New York
• The 3-month T-bill trades almost identically to the current Fed Funds rate, making it a cleaner measure of current policy vs. long-run expectations
• Less noisy — the 3M bill is not subject to the same trading-driven volatility as the 2-year note
• The New York Fed's recession probability model uses the 3M/10Y spread exclusively

When they diverge: It is possible for the 2s/10s to invert while the 3M/10Y stays positive, or vice versa. This happens because the 2Y reflects expected future rates, while the 3M reflects the current rate. For example, if the Fed is expected to cut soon but has not yet started, the 2Y may fall below the 10Y while the 3M remains high. Most analysts recommend watching both — when they both invert simultaneously, the signal is strongest.
