Alderstone-Holdings credit markets analyst Veronica Johnson examines alarming findings from Goldman Sachs’ institutional survey showing growing concerns about private credit vulnerabilities as oil shocks threaten financial stability.
While markets obsessed over the 8 PM ET Iran deadline, a Goldman Sachs poll of 784 institutional clients revealed deeper anxieties lurking beneath headline geopolitical fears. The survey, conducted between March 30 and April 1, showed investors increasingly worried about private credit market vulnerabilities that could trigger financial contagion.
The timing proved eerily prescient. Crude oil spiking to $115 per barrel on April 7 represented exactly the type of oil-driven shock that poll respondents flagged as a potential catalyst for private credit stress. The asset class that attracted hundreds of billions during low-rate years now faces its first real test.
The Private Credit Explosion
Private credit markets grew from roughly $500 billion in assets under management in 2015 to over $1.7 trillion by early 2026. The expansion accelerated as traditional bank lending contracted following regulatory changes, and rising interest rates made bond issuance expensive.
Middle-market companies unable to access public debt markets turned to private credit funds offering flexibility that banks and bond markets couldn’t match. Leverage levels reached 6x to 7x EBITDA in many deals, far exceeding historical norms.
The Goldman poll found that 62% of institutional investors expressed concern about underwriting standards deteriorating during the growth phase. Lenders competed aggressively for deals, potentially accepting weaker covenants and higher leverage to deploy capital.
The Transparency Problem
Unlike public bonds with standardized disclosure and pricing, private credit operates in opaque markets where valuations depend on internal models rather than observable transactions. This opacity creates information asymmetries that can hide problems until they explode.
Mark-to-model rather than mark-to-market valuation allows private credit funds to avoid recognizing losses during market stress. Public bond prices reflect real-time selling pressure. Private credit marks might lag reality by quarters.
The Goldman survey showed 58% of respondents worried about how illiquidity could amplify stress during adverse macro conditions. If borrowers default simultaneously, forced selling becomes difficult when no liquid secondary market exists for distressed private loans.
The Oil Shock Catalyst
$115 crude oil sustained for quarters creates recession conditions that stress corporate borrowers. Middle-market companies with high leverage and limited hedging face margin compression as energy costs spike while revenue softens.
Transportation, manufacturing, and retail sectors particularly vulnerable to oil shocks, represent significant portions of private credit portfolios. Defaults in these sectors could cascade as interconnected supply chains amplify stress.
The Goldman poll specifically flagged borrower sector stress as a concern, with 47% of respondents citing this risk. The geographic distribution of private credit portfolios concentrates in sectors that prospered during low oil prices but struggle when energy costs spike.
The Covenant-Lite Problem
During the deal-making frenzy of 2021-2023, covenant-lite loans became standard in private credit markets. These structures provide borrowers maximum flexibility but leave lenders with minimal protection if performance deteriorates.
Traditional bank loans included maintenance covenants requiring borrowers to meet quarterly financial metrics. Violations triggered renegotiation, where lenders could demand higher rates, additional collateral, or operational changes.
The Institutional Investor Exposure
Pension funds, insurance companies, and endowments increased private credit allocations significantly, attracted by yield premiums of 300 to 500 basis points over similarly rated public bonds.
But institutional investors often lack internal expertise to underwrite private loans or work out troubled credits. They delegate to private credit fund managers whose incentive structures prioritize asset gathering over risk management.
The Goldman survey found 52% of respondents were concerned about whether institutional investors fully understand the risks embedded in their private credit allocations. The asset class’s complexity exceeds what many allocation committees can adequately evaluate.
The Interest Rate Double Whammy
Rising interest rates in 2022-2024 already stressed floating-rate private credit borrowers. Many loans priced at SOFR plus 500 to 700 basis points now carry all-in rates exceeding 9% to 10%.
Companies that could service debt at 5% to 6% struggle when rates nearly double. Debt service coverage ratios deteriorate, consuming cash flow that otherwise would fund operations or growth investments.
The combination of high interest rates and energy cost spikes creates a perfect storm for middle-market borrowers. Fixed operating costs become less flexible to adjust when revenue declines, accelerating the path to default.
The Market Signal
The Goldman poll results surfacing amid the Iran crisis suggest sophisticated investors worry about multiple risks simultaneously. Geopolitical threats create immediate market volatility, but structural credit vulnerabilities pose longer-term dangers.
Private credit’s first real stress test approaches as macro conditions deteriorate. The asset class thrived during benign economic conditions and falling rates. How it performs during a recession and rising defaults will determine its long-term viability.
The 62% of institutional investors expressing concern about underwriting standards know they can’t easily exit positions if problems emerge. This creates a perverse incentive to hope for the best rather than demand transparency.
