Private Credit's Cockroach Moment Spreads to the Banks

The recent one-off blowups (BDC markdowns like BlackRock TCP Capital's 14% slide, surprise bad-loan disclosures rocking bank stocks) are the first cockroaches of a broader credit deterioration cycle, not idiosyncratic accidents. Over the next 9 months, losses migrate from private credit vehicles into regional bank books — KRE falls from ~$76 to below $65, and high-yield spreads widen from a complacent 282bps past 400bps.

The "cockroach theory" in credit holds that problem loans never come alone — the first visible markdown signals deteriorating underwriting across an entire vintage. The 2021–2023 private credit boom deployed $1.7T+ into leveraged loans at compressed spreads; at sustained elevated rates, the refinancing wall for these borrowers is becoming a structural stress event. Regional banks with middle-market and CRE exposure are the downstream victims when private credit vehicles can no longer absorb losses quietly, and HY spread widening is the public market signal that the credit cycle has turned.
