Private Credit AUM Growth and 2025 Stress Signals

Introduction

Private credit was one of the fastest-growing fixed-income segments through 2024-2025, with global AUM reaching approximately $3.5 trillion by year-end 2025 and the major platforms continuing aggressive growth. But the second half of 2025 brought the first meaningful stress signals to the asset class, with BDC NAV declines, redemption gating, and rising default rates all suggesting the "zero-loss fantasy" narrative around private credit may be ending. The 2026 outlook positions the asset class for its first major stress test as cumulative leveraged credit deterioration meets the structural features of private credit (illiquidity, lender concentration, weak covenants in some segments).

This article walks through the private credit AUM growth and 2025 stress signals in detail. It covers the cumulative growth trajectory across the major platforms, the specific stress signals emerging through 2025 (BDC writedowns, redemption gating, rising default rates), the underlying credit deterioration in specific sectors (software, automotive), the implications of the BlackRock/HPS acquisition completed in July 2025, and the structural considerations for the 2026 outlook. The framing is from the IBD DCM banker's seat, with leveraged finance origination and the major direct lenders as principal counterparties on private credit market intelligence.

Private credit has experienced extraordinary growth over the past decade, reaching approximately $3.5 trillion globally in 2025.

Growth Trajectory

The 2024-2025 growth rate accelerated meaningfully versus prior years, reflecting a combination of strong fundraising momentum, retail capital inflows through BDCs, and the BlackRock/HPS acquisition that consolidated significant existing AUM into a single new platform.

Major Platform Concentration

The growth has concentrated heavily in the largest platforms. The five largest listed alternative asset managers (Apollo, Ares, Blackstone, Carlyle, KKR) collectively manage approximately $1.5 trillion in perpetual capital, representing roughly 40% of their combined AUM and a meaningful share of total private credit.

Insurance Capital Acceleration

Insurance balance sheets have been a major driver of private credit growth. Insurance-linked capital platforms deployed an estimated $180 billion into private credit strategies in 2025, up from $120 billion in 2023. Apollo's Athene alone deployed $45 billion into private credit and asset-based finance in 2025, generating an average portfolio yield of 6.8% with 8.2-year duration.

Retail Capital via BDCs

Beyond institutional capital, retail capital flowing through non-traded BDCs has been a meaningful growth driver. Blackstone's BCRED grew to $66.6 billion AUM (the world's largest single private credit fund); Blue Owl's BDCs collectively manage substantial retail-accessed capital; and similar structures at other platforms have accelerated retail allocations to the asset class.

BDC (Business Development Company)

A specialized investment company structure under the Investment Company Act of 1940 that invests primarily in private credit and equity of US middle-market companies. BDCs provide retail and institutional investors with access to private credit through either publicly-traded shares (public BDCs like Ares Capital, Blue Owl Capital Corp, Owl Rock) or non-traded structures sold through retail brokerage platforms (Blackstone's BCRED, Apollo Debt Solutions BDC, Blue Owl Credit Income Corp). BDCs are required to distribute at least 90% of taxable income as dividends and are typically more leveraged than traditional asset managers (typically 1:1 debt-to-equity). The BDC structure has enabled retail capital to access private credit at scale, with combined BDC AUM growing dramatically over the past 5 years to anchor a meaningful share of total private credit market AUM.

The second half of 2025 brought the first meaningful stress signals to private credit after multiple years of broadly favorable conditions.

BlackRock TCP Capital NAV Decline

BlackRock TCP Capital Corp, a publicly-traded private debt BDC, disclosed that writedowns from a number of bad loans in its portfolio reduced its NAV by approximately 19% in Q4 2025. The decline was a stark warning signal for the broader BDC space and reflected concentrated exposure to credits that had deteriorated meaningfully.

Ares Strategic Income Fund Redemption Cap

Ares Management opted to curb investor withdrawals from its $10.7 billion private credit fund (Ares Strategic Income Fund) after withdrawal requests surged to 11.6%, capping redemptions in the fund at the standard 5% quarterly limit. The cap meant participating investors received only 5% of their requested redemption with the remainder rolling forward, illustrating the illiquidity inherent in private credit fund structures.

Non-Traded BDC Redemption Spike

Average redemptions across perpetually non-traded BDCs rose to 4.8% of NAV in Q4 2025 (up from 1.6% in Q3 2025), with five BDCs funding tenders above the standard 5% quarterly cap. The redemption pattern suggested broader investor concern about the asset class.

Default Rate Trajectory

Morgan Stanley warned that direct lending default rates (currently running around 5.6%) could reach 8% in stress scenarios, well above the 2-2.5% historical average. The headline default rate in private credit has remained below 2% for several years on standard reporting, but accounting for selective defaults and liability management exercises pushes the "true" default rate closer to 5%.

Sector-Specific Stress

Several sectors showed concentrated stress signals:

Payment-in-Kind (PIK) Toggle Increases

Rising use of PIK toggles in direct lending (where part of the coupon converts to additional principal rather than cash payment) signals borrower stress. PIK accommodation typically reflects borrowers unable to fund cash interest from operating cash flow.

Payment-in-Kind (PIK)

An interest mechanism in which a borrower pays its coupon not in cash but by adding the interest amount to the loan's principal, which then compounds. A "PIK toggle" lets the borrower choose, period by period, between paying in cash and paying in kind. PIK preserves a stressed borrower's cash but increases the debt balance over time, so a rise in PIK usage across a lender's portfolio is widely read as an early signal of borrower stress.

The 2025 stress signals have shifted how DCM bankers and leveraged finance teams engage with private credit and sponsor-led financings.

Increased Caution on Aggressive Pricing

DCM teams are calibrating private credit indicative term sheets more conservatively than in early 2025. Pricing assumptions have firmed, with less aggressive spread compression than the borrower-friendly Q1-Q2 2025 environment.

More Diligent Credit Selection

Direct lending platforms have become more selective on credit underwriting, with greater attention to cash flow stability, sector dynamics, and downside scenarios. Sectors with clear stress signals (software, automotive, certain healthcare) face tighter underwriting.

Covenant Package Evolution

Some private credit lenders are pushing for tighter covenant packages on new transactions, including more meaningful maintenance covenants, tighter restricted payments, and earlier-warning triggers. The trend may partially reverse the cov-lite drift of recent years.

Portfolio Monitoring Intensity

Major direct lenders have increased their portfolio monitoring intensity, with more frequent borrower engagement, more detailed financial review, and earlier intervention on emerging stress. The intensity reflects the broader credit deterioration in specific portfolio segments.

Communication With LPs

Platforms are providing more detailed communication with limited partners about portfolio composition, credit quality, and forward outlook. The communication is partly defensive (managing expectations during stress) and partly proactive (demonstrating sophisticated risk management).

The stress signals reflect a more challenging credit environment than the headline numbers suggest.

Cumulative Leveraged Credit Deterioration

The cumulative effect of multi-year elevated rates, sector-specific challenges, and weakening covenant protections has produced credit deterioration in specific corners of the leveraged credit market. While the broader IG and HY bond markets remain healthy, certain leveraged loan and private credit segments are showing earlier-cycle stress signals.

The "Selective Default" Phenomenon

A growing share of credit deterioration in private credit is being managed through "selective defaults" and liability management exercises rather than formal payment defaults. The accounting treatment masks some of the underlying credit deterioration but doesn't eliminate it.

Cov-Lite Documentation Effects

The cov-lite documentation that dominates large-cap private credit reduces lenders' early-warning visibility into borrower stress. Lenders may not have actionable information about credit deterioration until very late in the deterioration cycle, with implications for ultimate recovery rates.

Concentration Risk

Many private credit lenders have meaningful concentration in a few large positions, reflecting the structural lending dynamic. A single large credit event can produce material NAV impact, as the BlackRock TCP situation demonstrates.

The single largest private credit transaction of 2025 was BlackRock's acquisition of HPS Investment Partners.

Deal Mechanics

BlackRock completed the $12 billion all-stock acquisition of HPS Investment Partners on July 1, 2025. The transaction:

Strategic Rationale

BlackRock's strategic rationale combined:

Implications for the Industry

The acquisition signals continued consolidation pressure in the private credit industry. Several other major banks and asset managers have pursued or are pursuing direct lending capability through acquisitions or organic builds, suggesting continued M&A activity in 2026 and beyond.

The 2025 stress signals can be put in historical context to understand both their magnitude and the potential trajectory.

2008 Financial Crisis

The 2008 financial crisis produced severe stress in leveraged credit markets, with HY default rates exceeding 14% at peak and many BSL loans defaulting. Private credit was a much smaller market at the time (well under $500 billion globally) so the crisis impact on the asset class was limited. The 2025 environment differs because private credit is now an order of magnitude larger and has substantially deeper interconnections with banks and insurance balance sheets.

2020 Pandemic

The 2020 pandemic produced a sharp but brief credit shock. Private credit weathered the period reasonably well, partly because of substantial dry powder available for new lending and partly because the rapid policy response (Fed rate cuts, fiscal stimulus) limited the ultimate credit damage. The 2025 stress is more gradual and may extend longer than the 2020 shock.

2022-2023 Rate Volatility

The 2022-2023 rate-hiking cycle pressured leveraged credit but did not produce a full default cycle. Many borrowers managed through with the help of covenant relief, PIK accommodation, and amend-and-extend transactions. The 2025 stress builds on this base, with cumulative deterioration emerging after multiple years of accommodation.

Implications for 2026 Outlook

Historical patterns suggest credit cycles can extend for multiple years once stress emerges, with cumulative defaults building over 24-36 month windows. The 2025 stress signals could be early indicators of a multi-year credit cycle rather than a brief deterioration.

The 2025 stress signals have implications for sponsor-led portfolio companies that have used private credit financing.

Refinancing Considerations

Sponsor-led portfolio companies with private credit debt may face different refinancing dynamics in 2026 than they would have in 2024-2025. Direct lenders have less capital to deploy aggressively, may price more conservatively, and may apply tighter covenant packages on new transactions. Sponsors should plan for less aggressive private credit terms going forward.

Dual-Track Importance

The dual-track BSL/private credit process becomes more important as private credit pricing normalizes versus BSL. Sponsors that ran dual-track processes in 2024-2025 captured borrower-friendly economics in both markets through direct competition; sponsors that only engaged one channel may have left value on the table.

Capital Structure Optimization

Some sponsors are optimizing capital structures to combine BSL senior debt with private credit second-lien or unitranche structures, capturing BSL pricing efficiency on the senior portion while using private credit for structured layers. The hybrid approach may become more common as private credit pricing tightens.

Default and Restructuring Considerations

Sponsors of stressed portfolio companies face more challenging restructuring dynamics in private credit than in BSL. The bilateral or small-club lender structure produces concentrated lender power, and the lack of secondary trading means lenders cannot easily exit positions. Sponsors negotiating with private credit lenders on stressed credits face different dynamics than equivalent BSL situations.

The 2026 outlook for private credit is positioned for the asset class's first major stress test.

Continued Growth With Caveats

Major forecasts continue projecting private credit growth (BlackRock's view of doubling to $4.5 trillion by 2030). The growth trajectory remains intact even as 2025 stress signals emerge.

First Major Stress Test

The 2026 environment will test the asset class's resilience in its first major stress test: rising default rates; redemption pressures; sector-specific stress (particularly software/tech and automotive); and the cumulative effect of weak covenant documentation. How the major platforms manage through this test will shape the asset class's long-term trajectory and the broader credibility of private credit as an institutional asset class.

Regulatory Attention

Regulators are increasingly attentive to private credit. The lack of public disclosure makes systemic monitoring difficult, and the interconnections with banks and insurance balance sheets create channels for potential stress propagation. 2026 will likely see continued regulatory engagement on these issues.

Investor Segmentation

Different investor segments are likely to respond differently to the 2025 stress signals. Sophisticated institutional investors may continue allocating; retail investors through non-traded BDCs may pull back; insurance and pension allocations may continue gradually. The differentiated response could affect platform-specific dynamics.

The 2025 private credit stress signals fit into a broader narrative about the leveraged credit ecosystem and its evolution since the 2008 crisis.

Post-2008 Credit Restructuring

After the 2008 crisis, regulatory reforms pushed banks out of leveraged lending, creating space for the private credit industry to grow. The shift was structural: bank capital regulations made it economically unattractive for banks to hold sub-investment-grade corporate loans, and the asset managers stepped in to fill the gap. The cumulative effect was the $3.5 trillion private credit market we see in 2025.

Interconnections and Systemic Considerations

The growth has produced meaningful interconnections between private credit, banks, insurance companies, and the broader institutional investor base. Banks lend warehouse facilities to direct lenders; insurance balance sheets fund a substantial share of private credit; CLOs blur the line between BSL and private credit. These interconnections create channels for stress to propagate beyond private credit itself if the asset class faces sustained difficulty.

The "Shadow Banking" Question

Some regulators and commentators have characterized private credit as "shadow banking" because it provides credit intermediation outside the regulated bank framework. The characterization is technically accurate but doesn't necessarily indicate systemic risk: private credit is funded by long-duration capital (insurance, pension, private wealth) rather than short-term deposits, providing meaningful structural protection against the bank-run dynamics that characterized 2008.

Looking Forward

The private credit industry's 2026 stress test will help establish whether the asset class can manage through a meaningful credit cycle without producing systemic effects. A successful navigation would cement private credit as a permanent fixture of the institutional credit ecosystem; a more disorderly outcome could produce regulatory restrictions or capital flight that reshapes the asset class.

The private credit market remains one of the most consequential structural developments in fixed income, but the 2025 stress signals indicate the asset class is entering a more challenging environment.
