Credit

Default Cycle

The multi-year pattern of corporate default rates, driven by leverage build-up in benign periods and forced restructurings in downturns.

Definition

Default cycles typically last 5–10 years: leverage accumulates when credit is cheap, then a shock (rates, recession, sector-specific) triggers a wave of downgrades and defaults. Peak default rates usually arrive 12–18 months after spread peaks.

Moody's and S&P publish 12-month trailing default rates; Moody's also publishes a forward base/bear/bull forecast.

Why it matters

Default cycles drive HY total returns asymmetrically. Avoiding the worst 10% of credits typically delivers more alpha than picking the best.

Worked example

2020: HY default rate peaked at ~8% in late 2020 driven by energy and travel — well below the 14% Moody's bear case, thanks to Fed credit support.

Frequently asked

What's a normal default rate?
Through-cycle HY default rates average ~3–4%; recessions push them to 8–14%.
Which sectors default first?
Most leveraged, least cash-flow-resilient: retail, energy E&P, telecom in past cycles.
Does QE suppress defaults?
Yes — cheap refinancing extends the cycle but increases ultimate losses when it turns.
How do you trade the default cycle?
Long IG/short HY in late-cycle, long distressed in early-cycle recovery, long CCC in mid-cycle expansion.
