Credit Conditions (spreads)
Education only · our voice · free public data
Definition
The extra yield corporate bonds pay over Treasuries — a direct read on how much compensation investors demand to hold default risk, and one of the cleanest gauges of financial stress.
How to read it
Spreads (commonly the option-adjusted spread, OAS) tighten when investors are confident and widen when they fear defaults or want liquidity. High-yield (HY) spreads are more sensitive than investment-grade (IG). Because credit markets are dominated by institutions with access to fundamentals, credit is often treated as a 'smart money' tell: deteriorating credit while equities are calm is a classic warning. Direction and rate-of-change matter more than the absolute level.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Credit leading equities: HY OAS bottoming and turning up weeks before an equity top is a recurring sequence — credit prices in the cycle turn earlier because refinancing risk bites first. The CDX/cash-bond basis and primary-market issuance drying up can flag stress before secondary spreads fully reprice. Watch the lowest-quality cohort (CCC) relative to BB: CCC-BB decompression is an intra-credit risk-off signal that headline HY OAS smooths over.
