The European Central Bank has put private credit markets on notice. The central bank’s supervisory arm is flagging a constellation of risks in a sector that has quietly ballooned since the global financial crisis, from credit quality concerns to the sheer difficulty of figuring out who owes what to whom.

A trillion-dollar blind spot

Private credit, the catchall term for loans made outside the traditional banking system, has grown into a market estimated at $1.5 to $2 trillion in global assets by the end of 2024. Euro area private credit funds stood at approximately 106 billion euros as of the second quarter of 2024.

The ECB launched a dedicated monitoring exercise in early 2024 specifically targeting data gaps around banks’ exposures to private credit. The problem isn’t just the size of these markets. It’s that aggregating exposures across different business lines, identifying where risk is concentrated, and tracing how stress might spread from one corner of the financial system to another has proven genuinely difficult.

ECB Vice-President Luis de Guindos has gone further, classifying private credit as a significant emerging risk to financial stability.
