Private credit, the sprawling universe of non-bank lending that has quietly become one of the most important funding sources for mid-sized companies, is now firmly on the European Central Bank’s radar.

ECB Vice-President Luis de Guindos flagged private credit as a potential threat to financial stability on April 21, noting that high valuations and shifting fiscal policies make the sector particularly vulnerable. The warning came weeks after the ECB launched fresh supervisory checks on banks’ private credit exposures in March 2026.

The numbers behind the concern

The Financial Stability Board published a report on May 6 estimating that global private credit assets surged to between $1.5 trillion and $2 trillion by the end of 2024.

The FSB report identified several structural vulnerabilities: leverage that’s hard to measure from the outside, valuation opacity that makes it difficult to assess true portfolio health, and borrower credit quality that may be deteriorating beneath the surface.

Euro area exposure: limited but layered

The ECB’s current assessment is that euro area banks and insurers don’t have alarming direct exposure to private credit. Indirect risks are where things get more complicated. Many of the same corporate borrowers tapping private credit also have relationships with traditional banks. If a wave of defaults hit private credit portfolios, the stress wouldn’t stay neatly contained, bleeding into the broader corporate lending ecosystem through shared borrowers and interconnected credit facilities.

Barclays and Deutsche Bank have reported exposures of approximately $20B and $30B, respectively, in private credit. Neither institution views its position as posing systemic risk.

Why this matters beyond banking

The FSB report also highlighted intricate links between banks and private credit entities. Some banks originate loans and then sell them into private credit vehicles. Others provide leverage to private credit funds themselves. These interlinkages mean that a stress event in private credit could ripple back through the banking system in ways that are difficult to model precisely because the data isn’t comprehensive enough.

Regulators remain concerned about unlikely but possible scenarios involving sector-wide defaults that could cascade from private credit into the banking system. The ECB appears to be operating on the principle that you stress-test the roof while the sun is still shining.
