Wall Street is increasingly worried about hidden dangers in the $3 trillion private credit market, using vivid metaphors like 'cockroaches' to signal caution. This concern intensified after the September collapses of two companies financed by private credit, including one where JPMorgan Chase faced exposure. Jamie Dimon warned that one cockroach suggests more lurk unseen, a phrase quickly adopted industry-wide.

Blue Owl Capital, the largest public private credit firm, saw its shares plummet over 50% last year. A major worry is AI-driven software company failures, as the system shifts from benign conditions to visible risk. Regulators and experts constantly scan for distress signals, with Yale's Natasha Sarin warning weaknesses in this financial architecture could have 'seismic effects.' Other metaphors abound, from 'Wild West' to 'horses whinnying in the corral,' serving as coded warnings among insiders.
