Moody’s sees a nearly $2 trillion market financing larger hard assets, but layered structures and thinner equity cushions are changing the risk allocators actually own.
Private credit is evolving from a leveraged buyout financing channel into a source of system scale infrastructure capital. The opportunity set is expanding, but so is the distance between a loan’s legal form and its true economic risk.
Moody’s estimates that private credit managers are moving into utilities, infrastructure, and artificial intelligence data centres as those sectors confront substantial capital requirements. United States utilities alone are expected to spend roughly $250 billion annually through 2028, creating a funding need that public debt markets and banks may not absorb independently. For allocators, the expansion offers access to long duration hard assets with regulated or contracted revenues, alongside construction, policy, and interest rate risks.
Transaction size confirms how far the market has progressed. Moody’s highlighted Apollo’s $6.4 billion financing of the xAI data centre platform and the $10 billion investment by KKR and the Canada Pension Plan in Sempra Infrastructure Partners. Commitments of this scale were not available from private lenders five years ago. Manager selection must therefore account for the ability to evaluate technology, energy supply, regulation, construction schedules, and concentrated exposure rather than conventional borrower leverage alone.
Financing structures are also becoming more engineered. Minority investments in subsidiaries, ring fenced special purpose vehicles, and payment in kind instruments allow companies to fund large projects while limiting immediate pressure on their reported balance sheets. Sponsors may nevertheless retain exposure through guarantees, governance rights, or repurchase options. Moody’s argues that credit quality depends on whether risk has genuinely transferred, making collateral control, liquidity planning, and contractual enforcement central to institutional underwriting.
Insurer demand is accelerating this evolution. Managers are packaging hard asset loans into rated notes with layered claims and higher loan to value ratios, giving insurers assets that can better align with long dated liabilities. The tradeoff is a thinner equity cushion if collateral values fall. Moody’s said private credit reached about 18 percent of United Kingdom insurer investments in 2025 and approximately 11 percent across European Union insurers, increasing the relevance of valuation, liquidity, and correlation assumptions within solvency portfolios.
Most insurer exposure remains concentrated in investment grade residential mortgages, commercial property, infrastructure debt, and private placements. More complex assets and lower quality credit currently represent only about 2 percent to 3 percent of portfolios, according to Moody’s, but that share is growing. As private loans begin to resemble structured finance instruments, allocators must examine subordination, recovery priority, manager incentives, and the reliability of external ratings under stressed conditions.
Asset quality is becoming less uniform. Moody’s observed rising nonaccruals but found little evidence of broad stress, with lenders generally retaining sufficient capital and liquidity to absorb a downturn. That resilience is constructive, although private valuations can adjust more slowly than comparable public credit. Investment committees should therefore treat stable reported marks as one input rather than definitive evidence that underlying risk has remained unchanged.
The next phase of private credit will be defined by risk transfer rather than transaction volume alone. Allocators should monitor cash interest coverage, payment in kind accumulation, loan to value ratios, collateral quality, refinancing schedules, insurer regulation, and manager concentration. Infrastructure lending can improve diversification and liability alignment, but returns will depend on whether underwriting standards keep pace with the market’s growing size and structural ambition.
