The yield curve and why everyone watches it
When a two-year loan pays more than a ten-year one, the market is saying something bad.
The normal shape
Normally, lending long-term pays more than lending short-term. You demand an extra reward for locking your money up for ten years instead of two.
That gives a curve that climbs from left to right. It is the sign of a normal economy expecting growth and a little inflation.
Banks profit from that shape too: they borrow short-term and lend long-term, and the difference is their margin.
When it inverts
Sometimes the two-year bond pays more than the ten-year. That is an inversion, and it is strange: why would anyone accept less for locking their money up longer?
The answer is expectations. If the market believes the central bank will cut rates sharply within a few years — because the economy will slow — then locking in a rate today for ten years makes sense, even though it is lower.
So an inverted curve does not predict a recession directly. It shows that the market expects rate cuts, and big cuts usually come when something has broken.
As a signal, good but slow
Historically, in the United States an inversion has come before almost every recession. That has made it the most quoted signal in finance.
But the lag is long and unreliable — anywhere from six months to two years. An investor who exits the market on the day of the inversion can miss a year of gains before being proved right.
That is the usual pattern with macro signals: useful for understanding the context, almost useless for timing.
