Bank Lending Tightens as Private-Equity ‘Zombie’ Holdings Threaten Credit Flow

Across the United States, roughly 4,600 companies owned by private-equity funds have remained in portfolios for five years or longer, creating a backlog of “zombie” assets that are operational but lack a clear exit path. General partners now sit on more than $860 billion of net asset value in funds older than seven years, according to PitchBook analyst Kyle Walters. While the Federal Reserve Bank of Boston finds that banks’ senior secured claims on business-development companies would limit direct losses, its April 2026 Senior Loan Officer Opinion Survey reveals that banks are already tightening loan terms for private-equity sponsors.

This shift reflects supervisory concern that the exit delay and a looming private-credit maturity wall around 2028 could spill over into the wider credit system. Pension funds, university endowments and insurers also hold these aging stakes, but banks’ exposure poses a contagion risk that could tighten lending far beyond the private-equity sector. Optimists like Goldman Sachs CFO Denis Coleman note that deal activity is picking up, yet the scale of the backlog—31,000 unsold companies worth $3.7 trillion globally—remains a structural challenge.
