The 9-variable private credit due diligence.
Private credit is the fastest-growing alternative-investment category. Most retail entry points underprice the structural risks.
$1.7T inflows. Most retail entry points underprice the risk.
Private credit AUM has grown from $300B to over $1.7T in 14 years. Retail-accessible vehicles (BDCs, interval funds, ETFs) have proliferated. The structural risks — illiquidity, default cycle, manager concentration — are typically underpriced in retail marketing.
The nine indicators
The nine variables of credit due diligence.
Each is observable in the manager's documents, performance history, or industry positioning. The composite separates strong managers from average.
Manager track record across credit cycles
Threshold: 2+ cycles
Managers without experience through 2008 and 2020 cycles haven't been tested. Cycle exposure is the core information.
Sponsor relationships and deal flow
Pattern: deep PE relationships
Direct lenders source most deals from PE sponsors. Strong sponsor relationships produce better deal selection and pricing.
First-lien senior secured concentration
Threshold: > 80% first-lien
First-lien loans recover most in default. Subordinated or unsecured exposure raises tail risk.
Average loan size and diversification
Threshold: < 3% per name
Concentrated loan books amplify single-credit risk. Diversified portfolios with 30+ loans absorb idiosyncratic defaults.
Workout and recovery capability
Pattern: in-house team
Default workouts require specialized capability. Managers with in-house workout teams achieve higher recoveries.
Leverage on the fund
Threshold: < 1.0× fund leverage
Many private credit funds use leverage to amplify yields. Fund-level leverage adds risk on top of underlying credit risk.
Liquidity terms — gates and lock-ups
Pattern: quarterly with gates
Most retail private credit vehicles offer quarterly liquidity with gates — meaning withdrawal can be limited or denied during stress.
Fee structure
Pattern: 1.5/15 or richer
Private credit fees often run 1.5% management plus 15% incentive. The fees compress net yields meaningfully.
PE sponsor quality and exit history
Pattern: top-tier sponsors
Loans to top-tier PE-sponsored companies have lower historical defaults than middle-quality sponsors.
Why private credit grew so quickly
Post-2008 banking regulation reduced the appetite of traditional banks for middle-market lending. The vacuum was filled by direct lending firms — Apollo, Blackstone, Ares, Owl Rock, Antares, and dozens of others. The structural shift moved trillions of dollars of corporate lending from regulated banks to less-regulated alternative managers.
The growth has been remarkable but creates concentration. The largest private credit managers have grown faster than their underwriting capacity. Loan terms have loosened. Cov-lite structures are now standard. The sector has not been tested through a major credit cycle in its current scale.
Retail access points and their tradeoffs
Retail can access private credit via Business Development Companies (publicly traded BDCs like ARCC, MAIN), interval funds (Blackstone BCRED, Blue Owl), and increasingly ETFs (BIZD). Each vehicle has distinct liquidity, fee, and tax structures.
BDCs are most accessible but trade with discount/premium dynamics on top of underlying NAV. Interval funds offer better access to top-tier private credit managers but with quarterly liquidity gates. ETFs provide trading liquidity but limited access to the most premium managers.
Where the risks concentrate
The historical default cycle for direct lending shows 2–4 percent annual default rates in normal regimes, rising to 6–10 percent in stress. Recovery rates on first-lien senior secured loans typically run 60–80 cents on the dollar. The combined credit cost in stress can exceed 4 percent of the portfolio annually — meaningful for funds yielding 8–10 percent.
The concentration of private credit in PE-backed companies adds correlation risk. When PE exits soften (as in 2022–2024), the underlying portfolio companies face refinancing pressure simultaneously. The systemic risk of the asset class is higher than its diversified-loan-book appearance suggests.
Position sizing in retail portfolios
Private credit can play a role as part of a diversified fixed-income allocation, typically capped at 10–15 percent of the fixed-income sleeve. Higher allocations introduce concentration to a single asset class with limited liquidity and untested cycle exposure.
The discipline is to evaluate the manager and structure rather than the asset class category. A top-tier manager with strong track record, conservative leverage, and quality sponsor relationships can be a meaningful portfolio contributor. A growth-focused manager chasing yield through aggressive structures should be avoided regardless of the asset class label.

Common questions
Questions.
Is private credit better than HY bonds?
Different exposures. Private credit is illiquid, concentrated in middle-market PE-backed companies. HY bonds are liquid, broader. Risk-adjusted comparisons depend on cycle position.
What are interval funds?
Closed-end-fund-style structures with periodic (quarterly) liquidity windows. Allow access to less-liquid strategies than open-end mutual funds permit.
Are private credit yields sustainable?
Yields reflect the floating-rate nature of underlying loans plus credit spreads. As Fed rates change, yields adjust. Spreads have compressed in recent years; sustainable in current form is uncertain.
How does this compare to BDCs?
BDCs are the publicly-traded version of similar exposure. Interval funds and direct private credit funds offer access to wider manager universe at the cost of liquidity.
What's the tax treatment?
Most private credit is taxed as ordinary income, similar to HY bonds. Tax-efficient placement matters.
Will private credit blow up?
Sector-wide blowup is possible but not certain. The first major credit cycle will test the asset class. Manager selection and conservative position sizing reduce individual exposure to this risk.
