Does an Inverted Yield Curve Really Predict Recessions?
A reasoning-led walkthrough of a market signal that is genuinely useful, but often described more confidently than the evidence allows.
The claim everyone repeats
“The yield curve inverted, so a recession is coming.” That line is repeated with a certainty the evidence does not fully justify. The inverted curve has preceded essentially every US recession over the last half-century, which is a real and unusually clean regularity — but “preceded” is not the same as “predicts precisely.”
Why the simple version is incomplete
Lead time is long and variable: inversions have historically preceded recessions by anywhere from roughly six months to two years.
False positives matter: a signal is only useful if it helps you avoid being too confident too early.
The mechanism may be changing: heavy central-bank intervention can distort long-end yields for reasons that are not purely about growth expectations.
How I would frame the real question
What is the conditional probability of recession within a defined time window after inversion?
Which spread matters most — 10y–3m, 10y–2y, or both?
Has the relationship held up in the era of stronger central-bank balance-sheet intervention?
What the evidence broadly supports
The curve is a genuinely useful but imprecise indicator. It meaningfully raises the probability of recession over the following one-to-two years, but it is not a timing tool and it should not be treated as a deterministic forecast.
What I would not claim
I would not say “recession next quarter.”
I would not treat a single spread as the full story.
I would not assume the historical mechanism is unchanged in a structurally different market.
The transferable point is simple: the best analysis is neither dismissive nor overconfident. It finds the useful signal, states the limits clearly, and resists the temptation to turn a pattern into a prophecy.
