Yield Curve

A plot of bond yields against maturities, typically using government bonds. The shape of the curve — normal, flat, or inverted — provides clues about growth and inflation expectations.

How yield curve works

The basic concept:

X-axis — bond maturity (3-month, 2-year, 10-year, 30-year).
Y-axis — yield (interest rate).
Plot points — yields for each maturity.
Connect — produces curve showing rate term structure.
Most-watched — US Treasury yield curve.

The curve summarizes market expectations across time horizons.

Normal yield curve shape

Standard pattern:

Upward sloping — long rates higher than short.
Reflects time premium and inflation expectations.
Why — investors demand more yield for longer commitment.
Most common shape.

This represents healthy economic conditions.

Inverted yield curve

Notable anomaly:

Long rates below short rates.
Most-watched inversion — 10-year vs. 2-year (or 3-month).
Inverted yield curve — historically predicts recession within 6-24 months.
Mechanism — markets expect Fed to cut rates due to weakening economy.

The inversion of 2022-2024 preceded recession concerns globally.

Flat yield curve

Intermediate state:

Long and short rates similar.
Often a transition between normal and inverted.
Signals uncertainty about future economy.
Less directly predictive than inversion.

Flat curves often precede inversions or normalization.

What drives the curve

Several factors:

Fed policy — most directly affects short end.
Inflation expectations — affect long end.
Growth expectations — affect overall level.
Supply and demand — Treasury issuance, foreign buying.
Risk premiums — uncertainty premiums vary.

The curve incorporates many market expectations.

Why the curve matters

Several uses:

Recession prediction — inversions historically reliable.
Rate expectations — implied future Fed policy.
Bond pricing — basis for pricing all fixed income.
Mortgage rates — long-end rates affect mortgages.
Investment decisions — affects allocation across maturities.

The yield curve is one of the most-watched indicators in finance.

Yield curve history

Notable patterns:

Persistent inversions before 1970s, 1980, 1990, 2001, 2008, 2020 recessions.
2019 inversion preceded pandemic recession (some debate causation).
2022-2024 — significant inversion as Fed hiked aggressively.
2025-2026 — varies with conditions.

The "this time is different" claim has historically been wrong.

Yield curve and Fed policy

Critical relationship:

Fed sets short rate directly.
Long rate set by markets.
Steep curve — Fed accommodating; markets see growth.
Flat/inverted curve — Fed restrictive; markets see weakness.

Fed actions ripple through the curve.

What individuals should know

For investors:

Watch the 10-2 spread — most-cited recession indicator.
Yield curve affects everything from mortgage rates to savings rates.
Inversions signal caution; don't ignore.
Bond duration — yield curve shape affects bond strategy.

For mortgage borrowers:

30-year fixed rates roughly track 10-year Treasury.
Curve shape affects refinancing windows.

The yield curve is one of the most-information-rich indicators in finance. Understanding its shape and what it signals is foundational to interpreting macroeconomic conditions and market expectations.
