Key Takeaways
- • US life insurers collectively held $807 billion in private credit and illiquid assets in 2025, representing 20% of their $4 trillion fixed income portfolios, up from $685 billion (18%) in 2024, marking a significant year-over-year expansion in alternative asset exposure.
- • KKR-backed Global Atlantic Financial Group and Apollo-backed Athene Holding accelerated private credit allocations by approximately 30% during the period reviewed, outpacing the broader insurance market's growth trajectory and demonstrating the outsized role of alternative asset manager-affiliated platforms.
- • A concentrated group of approximately 10 large insurers controls $352 billion of private and illiquid investments, indicating substantial clustering of exposure within a limited number of balance sheets and raising potential systemic considerations around correlation risk.
- • Nearly 38% of insurers' private credit holdings consist of structured and asset-backed credit rather than traditional corporate or government debt, while close to 10% carry below-investment-grade ratings, reflecting increased complexity and credit risk in insurance portfolios.
- • The expansion reflects insurers' strategic pursuit of higher-yielding assets to match long-duration liabilities, creating a structural convergence between insurance capital flows and the private credit ecosystem.
Summary
US life insurers are substantially deepening their exposure to private credit and illiquid assets, according to analysis from Moody's Ratings cited by the Wall Street Journal. The sector's collective holdings of these assets grew to $807 billion in 2025, representing 20% of the industry's $4 trillion fixed income portfolio. This represents a notable increase from $685 billion held in 2024, when private credit and illiquid assets comprised 18% of fixed income allocations. The trajectory underscores the ongoing structural shift toward alternative assets within traditional insurance balance sheets.
The growth is being driven disproportionately by insurers affiliated with major alternative asset managers. KKR's insurance platform Global Atlantic Financial Group and Apollo Global Management's Athene Holding have led the expansion, each increasing private credit allocations by approximately 30% over the period reviewed. This pace of growth significantly outstrips the broader market expansion, positioning these platforms as primary architects of the insurance sector's pivot toward private markets.
Moody's analysis reveals a highly concentrated market structure. Approximately 10 large insurers account for $352 billion of the $807 billion in private and illiquid investments, meaning roughly 44% of the sector's exposure is concentrated within a small cohort of balance sheets. This concentration raises questions about correlation risk and systemic implications should market conditions deteriorate.
The composition of these portfolios introduces additional complexity. Roughly 38% of insurers' private credit holdings are tied to structured and asset-backed credit products rather than traditional corporate or government debt. Additionally, nearly 10% of holdings carry below-investment-grade ratings, reflecting a measured but discernible shift toward credit risk in pursuit of yield enhancement. This asset composition requires sophisticated risk management and detailed stress-testing protocols.
The underlying driver is straightforward: insurers seek higher-yielding assets to match long-duration liabilities inherent in their product portfolios. The convergence between insurance capital and private credit markets reflects rational capital allocation in a persistently low-rate environment, though the accelerating pace and concentration of this exposure merit continued regulatory and investor scrutiny.
