Key Takeaways:
Top U.S. insurance regulators are preparing to tighten oversight on the sector's rapidly growing exposure to private credit, announcing a new due diligence framework for spring 2026 after years of monitoring valuation discrepancies. The move by the National Association of Insurance Commissioners (NAIC) targets an asset class that has swelled to over $1.5 trillion in the closely-watched Bermuda reinsurance market alone.
"State insurance regulators are committed to rigorous oversight that keeps pace with rapidly changing insurer investment practices," Scott A. White, President of the NAIC and Virginia's Insurance Commissioner, said in a letter published on April 13.
The NAIC's planned "Credit Rating Provider Due Diligence Framework" follows measures implemented since 2018 requiring insurers to submit private ratings for greater transparency. The increased scrutiny comes as international regulators, including the IMF, have flagged potential systemic risks from the growing nexus of private equity and insurance, particularly in offshore hubs like Bermuda where PE-backed reinsurers manage vast blocks of pension and annuity assets.
The new framework signals a more aggressive regulatory stance, potentially forcing insurers to de-risk their portfolios and impacting profitability in the hunt for yield. For the private credit market, it could mean a reduced appetite from one of its largest capital providers, while policyholders may see a shift in the risk profile of long-term savings products.
The NAIC's actions mirror recent steps taken by regulators in Bermuda, a major hub for the global life reinsurance industry. The Bermuda Monetary Authority (BMA) has already enhanced its public disclosure regime, requiring reinsurers to provide detailed breakdowns of their assets and liabilities, a move supported by the industry group Biltir.
"It’s normal and appropriate for regulators to ask questions and to want to gain more clarity as a sector evolves," said Suzanne Williams, CEO of Biltir, which represents long-term insurers with over $1.5 trillion in assets under management.
Bermuda's regulators have focused on ensuring that the assets held by reinsurers, which include large allocations to private credit and other less liquid securities, are appropriately matched to the long-term nature of their liabilities. "An asset only needs to be as liquid as the liability that it’s matched against," Williams said, emphasizing the importance of asset-liability matching.
Concerns about the sector have centered on the potential for systemic risk, with the International Monetary Fund flagging the risk of "contagion" from offshore reinsurance in a 2023 report. In response, the BMA conducted a stress test last year modeling a 2008-style financial crisis. The results showed that 71 percent of the island's long-term reinsurers remained above a 150 percent capital adequacy ratio, which the BMA concluded highlighted the sector's resilience.
The NAIC has been observing growing discrepancies between ratings and the underlying risk of certain insurer investments for several years. The new framework aims to address this by giving regulators more power to challenge credit ratings and increase transparency, particularly in complex reinsurance transactions and private-equity acquisitions within the insurance sector. The public comment period for the framework this spring will be a key indicator of the final rules' stringency.
