Overview
Credit spreads are the difference between the yield on a corporate bond and the yield on a comparable government bond (or another benchmark) with similar maturity. When credit spreads widen, it usually signals rising risk premiums and tighter financial conditions. When spreads tighten, it often signals improving risk appetite and easier credit conditions.
Credit spreads are closely watched because they often move early when risk sentiment changes, especially during stress.
What it means in practice
Widening credit spreads typically reflect increased concern about default risk, growth risk, funding conditions, or broader uncertainty. Tightening spreads typically reflect improved confidence and stronger appetite for risk.
Credit spreads can influence other markets. When spreads widen sharply, equities can weaken, volatility can rise, and broader risk-off behaviour can take hold.
Why it matters in live markets
Credit spreads provide a cross-market signal about risk pricing. They can help confirm whether an equity move is broad-based stress or something more isolated.
Spreads can also influence liquidity and execution conditions during risk-off periods. When stress rises, market depth can thin and spreads across multiple assets can widen.
Key points
- Credit spreads reflect risk premium and stress in credit markets.
- Widening spreads often align with risk-off behaviour.
- Tightening spreads often align with risk-on behaviour.
- Credit spreads can move ahead of equities during early stress phases.
Example
If corporate bond yields rise while government bond yields remain stable, credit spreads widen. That often indicates investors are demanding extra compensation for credit risk, which can coincide with weaker equities and higher volatility.
