Private Equity's Leverage Problem: $1.2 Trillion in Buyout Debt Comes Due

Private equity firms have spent the past fifteen years borrowing cheaply to buy companies, strip out costs, and sell them at a profit. The model worked beautifully when central banks kept interest rates near zero. Now, with rates above 5% in the United States and the eurozone, the arithmetic has reversed. According to data from Preqin and S&P Global, approximately $1.2 trillion in leveraged buyout debt will mature between 2026 and 2028. Much of it was issued when benchmark rates were below 2%. Refinancing that debt at today's rates will cost, on average, three times as much in annual interest payments. This is, to put it mildly, suboptimal.

The consequences extend beyond Wall Street. Private equity now owns more than 11,000 companies in the United States alone, employing roughly 12 million people, according to the American Investment Council. In Europe, the figure is another 8 million. When overleveraged portfolio companies cannot service their debt, they cut jobs, delay capital investment, and in some cases file for bankruptcy. The retail, healthcare, and manufacturing sectors—where private equity ownership is concentrated—are particularly exposed. What began as a financial engineering problem is becoming an employment problem.

The Numbers

The scale of the problem is clearest in the data. Between 2010 and 2021, private equity firms completed more than 45,000 leveraged buyouts globally, worth a combined $4.8 trillion, according to PitchBook. The average deal was financed with debt equal to six times the target company's earnings before interest, taxes, depreciation, and amortisation (EBITDA). At the peak in 2020 and 2021, some deals reached leverage ratios of eight or nine times EBITDA. The loans were cheap: floating-rate debt tied to LIBOR or SOFR, which hovered near zero.

Today, SOFR stands at 5.3%. A company that borrowed $500 million in 2020 at SOFR plus 200 basis points paid roughly $10 million annually in interest. The same loan, refinanced today, costs $36.5 million. For companies already operating on thin margins—as many PE-owned firms do after cost-cutting measures—the difference is existential. S&P Global Ratings estimates that nearly 30% of speculative-grade loans issued by private equity-backed companies are at risk of default or distressed exchange by 2027.

The sectors most at risk are those where private equity binges were heaviest. Healthcare, particularly hospital chains and physician practices, saw more than $180 billion in PE-backed deals between 2018 and 2022. Retail—already battered by the shift to e-commerce—absorbed another $140 billion. Both sectors are now seeing credit downgrades. Moody's Investors Service downgraded 47 private equity-owned healthcare companies in 2025, citing unsustainable debt loads. Retail has fared worse: at least 22 PE-backed chains filed for Chapter 11 bankruptcy in the United States in 2025, including several with household names.

A Familiar Pattern

This is not the first time private equity has faced a refinancing crisis. In 2008 and 2009, as the financial crisis unfolded, PE firms found themselves unable to refinance debt taken on during the pre-crisis buyout boom. According to research from the Bank for International Settlements, roughly $400 billion in leveraged loans came due between 2008 and 2010, much of it at firms that had been acquired at peak valuations. Many portfolio companies defaulted. Others were sold at steep losses, or restructured in ways that wiped out equity holders—including the PE firms themselves.

The lesson, apparently, was not learned. After 2010, as central banks flooded markets with liquidity, private equity returned to the same playbook: high leverage, low margins for error, and the assumption that cheap credit would always be available. The Federal Reserve's first rate hike in March 2022 shattered that assumption. By mid-2023, the leveraged loan market had effectively frozen. New issuance fell by 60% compared to 2021, according to LCD, a unit of S&P Global. Firms that needed to refinance were forced to negotiate with lenders in private, often accepting worse terms.

The difference this time is scale. In 2008, private equity controlled roughly $2 trillion in assets globally. Today, the figure is $9.3 trillion, according to Preqin. The industry is larger, more systemically important, and more deeply embedded in the real economy. When a PE-owned hospital chain cannot refinance its debt, the consequences are not confined to investors. Emergency rooms close. Staff are laid off. Patients are transferred to facilities miles away.

The Mechanism

Why did private equity firms take on so much debt? The answer lies in the structure of returns. In a typical leveraged buyout, the PE firm contributes equity—often 30% to 40% of the purchase price—and borrows the rest. If the company's value increases, the equity holders capture the full upside, while creditors receive only their interest payments. This is leverage in the literal sense: a small amount of equity can generate outsize returns.

The model works brilliantly in rising markets with low interest rates. But it is fragile. If the company's value stagnates or falls, or if interest rates rise sharply, the debt becomes unsustainable. The equity is wiped out, and creditors take control. In effect, private equity shifts risk onto two groups: the companies' employees and customers, who bear the cost of cost-cutting and underinvestment; and the lenders, who are left holding loans that may never be repaid in full.

The lenders, it should be noted, are not innocent bystanders. Many of the loans were packaged into collateralised loan obligations (CLOs)—securities backed by pools of leveraged loans—and sold to pension funds, insurance companies, and other institutional investors. The CLO market is now worth roughly $1 trillion globally. If defaults rise, the losses will not be confined to a handful of hedge funds. They will ripple through the financial system.

What Is Being Done

Regulators have taken notice, albeit belatedly. In December 2025, the Federal Reserve, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation issued joint guidance reminding banks that loans with leverage above six times EBITDA are considered risky and should be avoided. The guidance is non-binding. It has been issued, in various forms, since 2013. Banks have largely ignored it.

In Europe, the European Systemic Risk Board published a report in January 2026 warning that private equity leverage poses a threat to financial stability. The report recommended stricter disclosure requirements and caps on leverage ratios. No legislation has followed. The European Commission, wary of driving PE activity to less regulated jurisdictions, has been reluctant to act.

The private equity industry, for its part, insists that the problem is manageable. In a February 2026 letter to investors, the American Investment Council argued that PE firms have ample "dry powder"—undeployed capital raised from investors—to support struggling portfolio companies. The figure cited was $2.6 trillion globally. This is true but misleading. Dry powder is earmarked for new deals, not bailouts. Deploying it to prop up overleveraged companies would reduce returns and anger the pension funds and endowments that supply the capital.

What Should Be Done

The immediate priority is transparency. Private equity firms are not required to disclose the debt levels of their portfolio companies in most jurisdictions. Investors—including public pension funds—often do not know how leveraged the companies they indirectly own actually are. Regulators should require quarterly disclosure of leverage ratios, interest coverage, and maturity schedules for all PE-backed companies above a certain size threshold. The Securities and Exchange Commission in the United States has the authority to impose such rules. It should use it.

Second, leverage limits should be binding, not advisory. The guidance issued by U.S. banking regulators is toothless because it carries no penalties. A statutory cap—say, six times EBITDA for any loan extended by a federally regulated bank—would force discipline. PE firms would still be able to borrow from non-bank lenders, but those lenders would demand higher rates, making extreme leverage less attractive.

Third, the CLO market needs scrutiny. Many CLOs are structured to hide risk, with the riskiest tranches held by entities that are lightly regulated or entirely opaque. The Financial Stability Board, the international body that monitors systemic risk, should conduct stress tests on CLO portfolios and publish the results. If significant losses are concentrated in pension funds or insurance companies, those institutions should be required to raise capital or divest.

Finally, policymakers should prepare for defaults. The 2008 crisis taught that disorderly bankruptcies impose larger costs on society than managed restructurings. Courts should be given resources to handle an expected surge in Chapter 11 filings. And regulators should clarify the treatment of workers and pensioners in PE-owned companies that fail. Too often, employees are the last to be paid.

The Reckoning Ahead

Private equity has grown fat on cheap credit and light regulation. For years, the model delivered impressive returns—at least on paper. But leverage is a wager on the future, and the future has arrived with higher interest rates and slower growth. The debt that seemed manageable in 2021 is now crushing. Some firms will survive by cutting deeper, selling assets, or securing last-minute refinancing. Others will not.

The broader question is whether regulators will act before the crisis metastasises. The tools exist: disclosure rules, leverage caps, stress tests. What is missing is political will. Private equity is a powerful lobby, and its leaders are skilled at framing regulation as an attack on free markets. But there is nothing free about a market built on hidden debt and socialised risk. The maturity wall is here. The only question is whether it will be climbed or whether it will collapse.
