Private Equity's Shifting Value Proposition in a Post-Interest Rate World

The post-2022 surge in interest rates has forced private equity to abandon its traditional playbook. For years, the industry thrived on financial engineering—leveraging debt to amplify returns, chasing multiple expansion, and relying on public market liquidity to fuel exits. But as central banks raised rates to combat inflation, the cost of capital soared, and the math of leveraged buyouts became less forgiving. Today, private equity firms are recalibrating their strategies, prioritizing capital efficiency and operational rigor over speculative bets. The question now is whether these adaptations can sustain risk-adjusted returns in a world where money is no longer free.

The New Arithmetic of Leverage and Liquidity

The most immediate impact of higher interest rates has been on leverage. According to a report by the VCI Institute, leverage ratios in buyout transactions have dropped from 6x EBITDA to 4.5–5x as lenders tighten terms and demand higher risk premiumsNavigating High Interest Rates in 2025: PE’s Winning Playbook^[1]. This shift has forced private equity firms to rethink how they structure deals. Earnouts—where sellers receive payments contingent on future performance—and seller financing at below-market rates have become tools to bridge valuation gaps and reduce upfront cash outflowsNavigating High Interest Rates in 2025: PE’s Winning Playbook^[1].

But the cost of debt isn't just a financing issue; it's a drag on portfolio company performance. With refinancing costs now 2–3 percentage points higher than at issuance, portfolio companies are under pressure to generate operational efficiencies to offset rising interest expenses.

These efforts are no longer optional—they're existential.

Extended Hold Periods and the Illiquidity Premium

The traditional private equity timeline—buy, fix, sell in five to seven years—is fraying. Public markets remain volatile, and trade sales have become harder to execute in a high-rate environment. As a result, hold periods are stretching. Data from Goodwin Law shows that North American private equity funds now average 7.1 years of ownership, while European funds hover at 5.9 yearsStretching and Flexing – Part 1 Addressing Longer Hold Periods^[2]. This extension isn't just a delay; it's a strategic recalibration.

Longer hold periods allow for deeper value creation but also demand greater patience from limited partners. To manage liquidity needs, general partners are turning to tools like GP-led secondaries and continuation vehicles. These structures let LPs exit portions of their investments while GPs retain control of high-potential assetsNavigating High Interest Rates in 2025: PE’s Winning Playbook^[1]. The tradeoff is clear: private equity's illiquidity premium is now being tested against the reality of extended capital lockups.

Private Credit: A New Engine for Returns

Amid these challenges, private credit has emerged as a bright spot. Structured with floating-rate loans, private credit instruments adjust with rising rates, offering yields of 8–10% in a world where base rates are 5–6%Navigating High Interest Rates in 2025: PE’s Winning Playbook^[1]. KKR has even proposed a 40/30/30 portfolio framework, allocating 10% to private credit to enhance diversification and risk-adjusted returnsPrivate Credit: 5 Charts All Investors Need to See in …^[4].

Yet the rapid growth of private credit—particularly among hyperscalers—has raised red flags. Underwriting standards have weakened in some corners of the market, and liquidity risks persist.

The key for private equity is to balance growth with prudence, ensuring that private credit remains a source of alpha rather than a new vulnerability.

The Operational Imperative

Ultimately, the shift in private equity's value proposition hinges on operational excellence. Financial engineering alone can't offset higher borrowing costs, but operational improvements can. A case study from Forbes highlights a logistics firm that boosted inventory turnover by 40% and cut freight costs by 18% through AI-driven supply chain optimizationNavigating High Interest Rates in 2025: PE’s Winning Playbook^[1]. Such gains directly enhance EBITDA margins, which are critical for maintaining valuation multiples in a high-rate world.

McKinsey's analysis underscores this point: private equity firms that prioritize operational value creation—such as supply chain restructuring and workforce alignment—achieve internal rates of return (IRRs) 2–3 percentage points higher than their peersBridging private equity’s value creation gap^[5]. These improvements also prepare portfolio companies for premium exits, a necessity in a market where public valuations remain depressed.

Risk-Adjusted Returns: A Delicate Balance

The jury is still out on whether these strategies will sustain private equity's historical risk-adjusted returns. Private credit's Sharpe ratio—measuring excess return per unit of risk—has outperformed U.S. stocks with 75% less volatility, according to T. Rowe PricePrivate Credit: 5 Charts All Investors Need to See in …^[4]. However, the tyranny of IRR remains a concern. As the CFA Institute notes, IRR can be misleading in private markets, where cash flows are irregular and liquidity is scarceBridging private equity’s value creation gap^[5]. Investors must look beyond IRR to metrics like Sharpe ratios and stress-testing to gauge true resilience.

Conclusion: A New Normal

Private equity's post-interest rate world is defined by tighter capital constraints, extended timelines, and a renewed focus on operational rigor. The industry's ability to adapt will determine whether it can maintain its allure as a source of alpha. For now, the evidence suggests that firms embracing operational excellence and private credit's yield potential are best positioned to navigate the new normal. But as always, the line between innovation and overreach is razor-thin.
