The yield curve plots Treasury yields across maturities. The most-watched version is the 10-year yield minus the 2-year.
Normally the long yield sits above the short one and the curve slopes upward, because lenders want more to lock their money up for longer. A positive, upward-sloping curve is the ordinary state of the world.
When short yields rise above long yields, the curve inverts and the spread goes negative. That tends to happen when the market expects rates to fall, often because policy is restrictive now and growth is expected to slow later.
Un-inversion, the curve moving from negative back to positive, is the curve normalizing. In the historical record, deep inversions have preceded slowdowns, and the un-inversion that follows has often arrived near the turn. Read that as an association, not a clock. The curve is a backdrop, not a timing tool, and it has been early and wrong before.
How it reads against the lens: a steepening curve eases pressure on the rate-sensitive corners of the market, which is part of why some sectors sit calmer than others at any given moment. It is context, not a signal to act on.
