The risk is not evenly distributed. While banks’ exposures remain contained, the ECB’s analysis points to the non-bank financial sector—specifically insurance corporations and pension funds—as the most vulnerable link .

The €263 billion exposure: insurers and pension funds in the crosshairs

The FSR provided granular data on where the direct risk sits:

• Insurance corporations hold approximately €211 billion in private credit, equivalent to 2.3% of their total assets .
• Pension funds hold approximately €52 billion, equivalent to 1.4% of their total assets .
• Combined, these two sectors carry roughly €263 billion in direct private credit exposure .

To quantify the danger, the ECB simulated a “severe” shock to the market. The three-stage exercise modeled direct private credit losses, further hits from loans to correlated sectors like software firms, and finally, broader second-round revaluation losses through equity and bond markets . The result: European insurers and pension funds would likely be hit harder than banks, largely because of their larger and less senior exposures . In absolute terms, insurers faced the biggest hit in the simulation.

Spillover risks: from private credit to public markets

A key focus of the review is how stress in the opaque private credit market could cascade into publicly traded assets. The ECB flagged that revaluation losses on private credit portfolios could force fire sales or rapid deleveraging that spills into leveraged loans, high-yield bonds, and equities .

The central bank’s broader financial stability warning reinforces this concern: “Price adjustments in stretched and concentrated asset markets risk becoming disorderly,” particularly if liquidity and leverage fragilities in the non-bank financial sector amplify the swings . This creates a transmission mechanism where a problem born in unlisted, illiquid loans can end up rattling exchange-traded markets that affect a much wider pool of investors.

Opacity, ‘lend and extend,’ and the hidden default problem

The ECB raised a red flag about the opacity of a sector that has swelled to an estimated $1.5 trillion to $2 trillion globally, much of it outside the perimeter of traditional banking regulation and disclosure . Within the euro area, the central bank warned that private credit-backed firms are finding it “harder to service interest payments,” signaling a steady deterioration in borrower health .

The report calls for enhanced data infrastructure and regulatory oversight to close information gaps that currently make it difficult to assess true risk levels .

This opacity is not just a European concern. The Financial Stability Board (FSB), in its own Report on Vulnerabilities in Private Credit published on May 6, 2026, echoed many of the same themes. The FSB highlighted that the “opacity of valuations and the ‘lend and extend’ practice”—where lenders roll over troubled loans rather than recognize losses—could mask accumulating risks . In a stressed scenario, the FSB warned, liquidity mismatches and interconnections with the broader financial system could amplify an initially localized problem.

What the default data actually shows

The ECB’s warnings didn’t emerge in a vacuum. U.S. private credit default data released in the weeks before the review painted a deteriorating picture of borrower health, adding urgency to the European assessment:

• Fitch Ratings reported that the U.S. Private Credit Default Rate (PCDR) hit a record 6.0% for the trailing twelve months ended April 2026, up from 5.7% in March—the highest since the index launched in August 2024 . Ten private credit defaults were recorded in April alone, with seven involving maturity extensions described as under stress .
• Moody’s analysis indicated that the 2025 private credit default rate likely fell between 1.6% and 4.7% depending on whether distressed exchanges were included . Crucially, Moody’s found that roughly 65% of all corporate default events in 2025 were distressed restructurings—amend-and-extend maneuvers that push maturities out rather than forcing a full default. Excluding these events sharply lowers the headline rate but “risks understating the true stress” in the market .
• The Proskauer Private Credit Default Index, which tracks senior-secured and unitranche loans in the U.S., registered a default rate of 2.73% for Q1 2026, up from 2.46% in Q4 2025 and 1.84% in Q3 2025 .

These figures explain why the ECB and FSB are focusing on what they can’t see. The wide gap between Fitch’s 6.0% and Proskauer’s 2.73% highlights the sector’s fundamental measurement problem: different methodologies, different samples, and the pervasive use of distressed exchanges all make it difficult to know how much stress is really being deferred.

What it means

The ECB’s May 2026 FSR draws a careful line. The euro area is not on the verge of a private-credit-driven financial crisis. The direct exposures are too limited, and the connections to banks too contained, for that to happen today. But the review makes equally clear that parts of the financial system—insurers and pension funds with €263 billion in direct exposure—are already feeling the pressure. The real danger lies in the spillover channels: a deterioration in private credit portfolios that forces markdowns, triggers asset sales, and bleeds into the leveraged loan, high-yield bond, and equity markets where the broadest investor losses would be felt.

For now, the biggest risk is what remains unseen. As long as restructurings outnumber true defaults and valuations are marked only intermittently, both regulators and investors are watching a stress that may be deeper than the headline numbers suggest.
