The private credit asset class is confronting growing risks just as a new wave of US pension fund capital prepares to enter the market. The dynamic, described by some senior market participants as the late innings of a boom, is attracting regulatory scrutiny and investor caution, with implications for UK pension schemes and asset managers also building exposure to the sector.

A market reaching a pivotal moment

Private credit, which has grown into one of the most substantial alternative asset classes globally, is reaching a pivotal moment. The sector has expanded dramatically over the past fifteen years, with total assets under management now measured in trillions of dollars. The expansion has been driven by the retreat of traditional banks from mid-market lending, the willingness of long-term investors to seek the yield premium associated with illiquid credit and the development of a sophisticated manager base capable of deploying capital at scale. As the asset class matures, questions about its resilience, its fundamental characteristics and the appropriateness of further capital inflows have become more pointed.

The immediate context is the combination of two linked developments. First, a series of indicators, including rising default rates in specific parts of the market, increased use of payment-in-kind structures to manage borrower distress, covenant-lite lending that has constrained lender options, and concerns about the valuations assigned to portfolio holdings, has raised questions about the quality of recent vintages. Second, a substantial wave of US public pension fund capital is anticipated to enter the market over the coming years, as trustees seek higher returns to address funding gaps and build on the initial allocations made by leading schemes. The interaction between these dynamics, with growing risks meeting growing inflows, is a subject of intense market and regulatory discussion.

For UK pension funds, asset managers and financial stability authorities, the US dynamics are highly relevant. UK institutional investors have built material exposure to US private credit, either directly through separate accounts or through commingled funds operated by specialist managers. UK asset managers, including some of the largest global firms, are significant participants in the market. The UK's regulatory authorities, while formally responsible for UK entities, engage actively with international counterparts on matters of financial stability and asset class integrity. The US private credit story is, in multiple ways, a UK institutional investor story as well.

Signals of rising risk

A number of indicators have contributed to the sense of rising risk in the private credit market. Default rates, while varying by segment and by manager, have ticked upwards in recent quarters from the historically low levels of the immediate pre- and post-pandemic period. The underlying drivers include higher interest rates, which have increased debt service burdens for leveraged borrowers, and sector-specific pressures in categories including software, healthcare services and consumer-facing businesses. Workout and restructuring activity has increased, with some managers devoting more resources to the management of distressed portfolio companies.

Payment-in-kind and amend-and-extend

The increasing use of payment-in-kind interest, in which accrued interest is added to loan balances rather than paid in cash, has attracted attention. While PIK is a legitimate structural feature that can support borrowers through temporary stress, its growing prevalence in portfolios can mask underlying cash flow problems and defer rather than resolve issues. Amend-and-extend transactions, in which loan terms are adjusted to avoid formal default, have also been observed at elevated levels. The interpretation of these trends is debated, with some observers seeing them as necessary portfolio management and others as signals of growing stress that is being managed to show smoother headline metrics than the underlying reality.

Covenant erosion

Covenant erosion has been a longer-running concern in the private credit market, reflecting the competitive dynamics of capital deployment. In the more benign environment of recent years, the willingness of lenders to accept weaker covenant structures has constrained their ability to intervene when borrower performance has deteriorated. As the market adjusts to higher rates and more challenging operating conditions for some borrowers, the consequences of weaker covenants are becoming more apparent. Leading managers with disciplined credit processes are likely to differentiate from those with more permissive approaches, but the overall market performance is affected by the cumulative effect of past underwriting.

Valuation practices

Valuation practices in private credit have been a persistent area of concern. Loans are typically marked by the manager using internal valuation methodologies, with limited reference to observable market prices. The resulting valuations can lag actual changes in credit quality, particularly in stressed conditions. The smoothness of reported returns relative to public credit markets partly reflects these valuation approaches, and the true volatility of the asset class may be higher than the headline metrics suggest. Improved transparency and valuation discipline have been subjects of regulatory focus.

The wave of US pension capital

Against this evolving risk backdrop, US public pension funds are preparing to allocate significant additional capital to private credit. Several of the largest funds have signalled meaningful increases in target allocations, with commitments in the multi-billion-dollar range planned over the coming years. The drivers are familiar: the need to generate returns that can support funding of ongoing benefit obligations, the perception that private credit offers attractive risk-adjusted returns, and the willingness of long-term investors to accept illiquidity in exchange for yield premium.

Funding status and allocation pressure

US public pension funds collectively manage trillions of dollars in assets and face well-documented funding challenges. While funded ratios have improved in recent years, reflecting both asset growth and contribution increases, the underlying obligations require returns of six to seven per cent or more to be achievable over long horizons. The search for such returns in an environment where traditional equity and bond allocations may not deliver them has driven continued allocation to alternatives, with private credit one of the categories receiving increased attention.

Manager selection and competitive dynamics

The process by which public pension funds select private credit managers is highly competitive among the fund managers themselves. Winning large mandates requires demonstrable track records, significant firm scale, robust operational infrastructure and, increasingly, willingness to accept fee structures that reflect the scale of the commitment. The concentration of capital among large, established managers has been a feature of the sector, and the coming wave of inflows is likely to reinforce this pattern, with possibly some stretching of capacity at mid-tier managers that succeed in winning mandates.

Regulatory and policy attention

Regulatory attention on private credit has intensified in recent years. The US Federal Reserve, the Office of the Comptroller of the Currency and the Securities and Exchange Commission have all engaged with aspects of the sector, with focus including the interconnections between private credit and the banking system, the accuracy of valuations, the disclosure of risks to investors, and the potential systemic implications of sustained growth. The Financial Stability Board and the International Monetary Fund have also published analyses highlighting specific areas of concern.

UK regulator engagement

The UK's Financial Conduct Authority and Prudential Regulation Authority engage with private credit through multiple channels, including direct oversight of UK-based managers, supervision of UK-regulated institutional investors with exposure and participation in international regulatory coordination. The Bank of England has highlighted private credit as an area of interest in its financial stability analysis. The regulatory framework for the sector in the UK is generally considered robust, but the interaction of UK rules with the international nature of the asset class means that effective supervision requires ongoing coordination with international counterparts.

Bank-private credit interactions

The relationships between banks and private credit managers have attracted specific regulatory attention. Banks are significant providers of leverage to private credit vehicles, are sometimes referral sources for private credit transactions, and in some cases operate private credit businesses themselves. The potential for risk to migrate between the formally regulated banking sector and the less intensively regulated private credit sector, with implications for systemic risk assessment, is an area of ongoing analysis. The management of these interconnections, in ways that support the legitimate business while ensuring adequate oversight, is a regulatory priority.

UK institutional exposure and strategy

UK institutional investors' approach to private credit has combined enthusiasm with caution. Large pension schemes, insurers and asset managers have built meaningful exposure, but typically through careful manager selection, attention to vintage and strategy diversification, and governance frameworks designed to manage the specific characteristics of the asset class. The experience of UK investors in private credit has been generally positive through recent periods, though the true test of the asset class in UK portfolios will come through a more pronounced credit cycle than has yet been experienced in its modern institutionalised form.

Manager due diligence evolution

Due diligence practices for private credit have evolved significantly. Leading UK institutional investors now conduct detailed assessments not only of headline track record but of underwriting processes, portfolio management capabilities, workout experience, valuation governance and operational infrastructure. The integration of environmental, social and governance considerations has also advanced, with expectations that managers demonstrate robust approaches to credit-specific ESG issues. The raising of due diligence standards supports better outcomes but also increases the cost and complexity of allocating to the asset class.

Strategy and structural choices

UK investors have diversified their private credit exposure across multiple strategies, including senior direct lending, subordinated and junior debt, asset-based lending, specialty finance, real estate and infrastructure debt, and opportunistic and distressed credit. The relative attractiveness of each strategy varies with market conditions, and portfolio construction involves active decisions about strategy allocation as well as manager selection. Structural choices, including the use of separate accounts, commingled funds, co-investment arrangements and secondary transactions, provide additional dimensions of portfolio design.

The broader macro context

The macro context for private credit includes the evolution of interest rates, the path of economic growth, sectoral dynamics in the corporate sector, and the performance of leveraged borrowers. The recent rate environment has been challenging for borrowers with significant floating rate debt, and the outlook for rates is a key input into credit performance assessments. Economic growth trajectories, both in the United States and in the global economy, affect the broader context for corporate performance and therefore for credit risk. Sector-specific dynamics, including in technology, healthcare, consumer and industrial sectors, interact with the portfolio composition of private credit managers to shape overall performance.

A more pronounced credit cycle, with elevated default rates and lower recoveries, would test the resilience of the private credit model and the quality of individual manager execution. The ability of managers to work out problem loans, to restructure distressed borrowers effectively and to recover value in difficult circumstances would become visible and would reshape competitive dynamics in the sector. The experience of such a cycle would also inform the future willingness of institutional investors to maintain or expand their allocations, affecting the trajectory of the asset class over the subsequent years.

Outlook: maturation, not reversal

The most likely outlook is for continued maturation of the private credit asset class rather than reversal. The underlying economics of the sector, including the retreat of banks from middle-market lending and the willingness of long-term investors to seek yield, remain supportive. The anticipated inflows from US pension funds, though raising questions about capacity, represent continued institutional endorsement of the category. The regulatory attention, while creating some additional compliance burden, is unlikely to fundamentally reshape the asset class in ways that would diminish its core role.

However, the character of the asset class is evolving, with increased differentiation among managers, greater attention to vintage and strategy selection, and more developed frameworks for risk management and disclosure. The combination of rising risks in the current cycle and continued capital inflows creates an environment in which manager selection and disciplined allocation become more important than simple exposure to the asset class. The period ahead will reward those investors, managers and regulators who navigate these complexities effectively and will expose those who do not.

For UK pension schemes and asset managers, the US developments carry multiple messages. The general direction of institutional allocation towards private credit is validated by US trustee behaviour, supporting continued UK engagement with the category. The specific risks highlighted in US analysis and regulatory commentary are largely relevant to UK investors as well, and call for careful risk management. The potential for spillover effects from any US-centred stress to UK holdings is real and requires consideration in portfolio construction and risk monitoring. The coming years will test the combined capability of the global private credit ecosystem to manage the transition from rapid growth to sustainable maturity, and the outcome will matter both to the institutions directly involved and to the broader financial system of which they are part.
