Stress-Testing a Private Credit Fund's Portfolio Against 3 Macroeconomic Scenarios

Summary 

We conducted a comprehensive credit risk assessment for a US-focused private credit fund, stress-testing its portfolio across rate shocks, sector downturns, and liquidity squeeze scenarios. By integrating borrower-level financials, covenant structures, and macroeconomic variables, we quantified downside risks, default probabilities, and recovery outcomes. The analysis enabled portfolio rebalancing, improved risk-adjusted returns, and strengthened investor confidence amid tightening financial conditions and elevated volatility in credit markets.

Identifying Challenges

• Limited borrower-level forward projections constrained accurate estimation of default probabilities and recovery rates under stressed macroeconomic and sector-specific conditions.
• Covenant-lite structures reduced early warning signals, complicating detection of financial deterioration and delaying proactive portfolio risk mitigation actions.
• Fragmented data across portfolio companies hindered consistent modeling of leverage, interest coverage, and cash flow resilience under varying rate environments.
• Illiquidity in private credit markets limited price discovery, making mark-to-market adjustments and valuation benchmarking highly subjective and inconsistent.

Our Solution

• Developed a multi-scenario stress testing framework incorporating three distinct macroeconomic environments rate shock, sector downturn, and liquidity squeeze linking top-down macro variables such as interest rates, GDP slowdown, and credit spreads to bottom-up borrower financial performance.
• Built borrower-level cash flow models for each portfolio company, integrating revenue sensitivity, margin compression, and refinancing assumptions to simulate EBITDA decline, debt servicing capacity, and default likelihood under each stress scenario.
• Conducted covenant analysis across the portfolio, mapping leverage ratios, interest coverage thresholds, and liquidity covenants to identify breach points and estimate timing of covenant violations under stressed conditions.
• Quantified expected credit losses (ECL) and recovery rates using scenario-weighted probability frameworks, incorporating sector-specific downturn assumptions and capital structure positioning to assess loss given default (LGD) across the portfolio.
• Designed a portfolio aggregation engine to consolidate borrower-level outputs into fund-level risk metrics, including stressed IRR impact, NAV drawdown, and concentration risks across industries and sponsor exposures.
• Delivered actionable insights, including risk-based portfolio rebalancing strategies, sector exposure adjustments, and refinancing prioritization, enabling the fund to proactively manage downside risks and optimize capital allocation decisions.

Highlights
