High Yield Spread
The high yield spread is the extra yield investors demand to hold riskier corporate bonds instead of government bonds of similar maturity. It is compensation for the possibility that the borrower does not repay.
How it is measured
The spread is the difference between the yield on a basket of below investment grade corporate debt and the yield on comparable government debt, quoted in basis points or percentage points.
It moves for two distinct reasons that are worth separating: changes in how likely default is thought to be, and changes in how much investors are willing to be paid to bear that risk at all.
How to read it
Widening means lenders are demanding more compensation, which is a statement about perceived risk in the real economy rather than about market sentiment. Tightening means the opposite, and very tight spreads can themselves be a warning that risk is being underpriced.
Credit markets have historically been an earlier and less noisy signal than equity markets, because bondholders are paid to think about downside and have no upside to distract them.
A worked example
Equity indices can sit near highs while credit spreads widen. That divergence is informative: equity holders are pricing continued growth while lenders are pricing rising default risk, and the two cannot both be right indefinitely.
The most common mistake
Reading a single spread level as good or bad without context. The same absolute level means different things at different points in the cycle and under different policy regimes. Direction and rate of change are usually more informative than the level.
How CORVIX uses it
The high yield spread is one of the inputs to CORVIX's credit category in the business cycle classification, and it also feeds the correction risk estimate. When the primary credit measure is unavailable, the spread serves as the documented fallback rather than the field being silently dropped.
