Buyout Returns Were Financed by a 40 Year Slide in Interest Rates. That Slide Is Over.

What's New

The institutions that moved their equity from public to private markets were solving a rate problem, and the rate problem has reversed. Morgan Stanley's Counterpoint Global argues in its long term study of the shift from public to private equity that pension funds and endowments bought buyout and venture exposure because the 10 year Treasury yield fell from 15 percent in 1981 to 0.9 percent in 2020 while their liabilities kept growing. That yield is now 4.7 percent and the real yield has climbed from roughly negative 1.0 percent in late 2021 to 2.4 percent in August 2026, so the gap private assets were hired to close has narrowed on its own. The familiar statistics still hold: listed companies have halved since 1996, private capital raised has more than doubled public capital raised every year since 2020, and allocations to alternatives have reached 35 percent at state pensions and 55 percent at endowments. But the public market remains 25 times the size of buyout AUM and 50 times venture AUM, and the average private fund returns that justified the shift conceal dispersion wide enough that manager access decided most of the outcome. The authors treat public and private equity as complements and warn that the industry enters 2026 with record dry powder, a record exit backlog, and a cost of capital it has not operated under since the 1990s.

Why It Matters

Both engines behind the shift, falling risk free rates and cheap leverage, have reversed at the moment the industry is most exposed. GPs must now earn returns through operating improvement rather than multiple expansion, and the report's finding that buyout persistence has faded since 2000 means LPs cannot rely on track records to find the managers who can. With almost 90 percent of LPs at or near their private equity targets, the next leg of growth depends on retail retirement plans rather than institutions. For technology platforms, continuation funds, secondary buyouts, private credit financing, and semi liquid retail vehicles are stretching the valuation and liquidity infrastructure of private markets well beyond what it was built to carry.

Big Picture Drivers

• Pension math forced the search for risk: CalPERS assumed a 6.8 percent return while 10 year Treasuries yielded 0.65 percent in June 2020, a 6.35 point gap only private assets could plausibly close. Pensions raised alternatives from 7 percent of assets in 1990 to 35 percent in 2025; endowments went from 6 percent to 55 percent.

• The credit stack made leverage abundant: High yield bonds in the 1980s, leveraged loans since 2000, CLOs that now hold 75 percent of the loan market, and private credit that financed about half of buyout deals in 2025 each lowered the cost of buying companies with debt. Covenant lite issuance rose from 70 percent of the market to 90 percent in a decade.

• Regulation opened the private door: The 1979 prudent person clarification, the 1996 National Securities Markets Improvement Act, and the 2006 Pension Protection Act each cut the friction for institutional capital to go private. The 2025 tax law and Executive Order 14330 on 401(k) access extend the pattern.

• Smoothed marks are a feature, not a bug: GPs mark their own holdings, which makes private funds look calmer than their economic exposure justifies. Research cited in the report finds that exposure resembles public markets, and many LPs welcome the "phony happiness" because it calms boards and regulators.

• Companies stay private because they can: Late stage rounds grew from 10 percent of venture investment in 1980 to 70 percent in 2025, unicorns from 3 in 2006 to 945 by mid 2026, and tender offers rose 60 percent in 2025. GenAI has revived capital hunger, with OpenAI, Anthropic, and xAI raising enormous sums on negative free cash flow.

• The active to passive rotation reshaped the public side: Since 2006 investors have put $3.5 trillion into index funds and ETFs and pulled $3.4 trillion from active funds. Equity funds saw net outflows in most years since 2008 even as the S&P 500 compounded at 11.5 percent over 40 years.

By The Numbers

• $2.9 trillion: U.S. buyout AUM at year end 2025, including $0.8 trillion of dry powder worth almost $1.8 trillion of purchasing power at a 45 percent equity contribution.

• $825 billion to $375 billion: Buyout exits fell by more than half from the 2021 peak to 2025, lifting assets in funds 10 years or older from $4 billion in 2005 to $350 billion.

• 11.5x: Median EV/EBITDA for buyout deals in 2025, up from 6.6x in 2000. Low entry multiples, not high ones, have historically produced high public market equivalents.

• 12 percent: The EBITDA growth a 2025 deal needs to match the 2.5x MOIC a 2015 deal earned on 5 percent growth, given higher multiples, 8 to 9 percent debt costs, and lower leverage.

• 1.2x and 1.4x: Long run public market equivalents for buyout and venture funds. Bottom quartile funds in both categories trailed the S&P 500 while charging high fees.

• $250 to $500 billion: Morgan Stanley's bottom up estimate of incremental retail retirement demand for private equity over three to five years, drawn from a $5 trillion target date fund pool and well below the $1 trillion figures in circulation.

Key Trends to Watch

• The DOL safe harbor decision: The Department of Labor proposed a fiduciary safe harbor in March 2026 and received 47,000 comments by June. If finalized, retail access will run through target date and multi asset funds, and the semi liquid retail vehicles that already exist have underperformed industry benchmarks.

• Continuation funds as the new exit: Secondary buyouts were nearly half of all exits in 2025, and continuation vehicles grew from a handful in 2018 to more than 100 in 2025. The question is whether LPs keep accepting GP led liquidity or press for cash distributions.

• Software overhang in buyout portfolios: About 1,200 of 13,500 buyout owned companies are software businesses bought above average multiples. The report names GenAI as a strategic risk to the sector and notes the software ETF fell 17.2 percent in the year to July 2026.

• Venture concentration in late stage AI: 2025 was the second highest venture investment year on record, driven by AI, and the industry holds $300 billion of dry powder, four times annual fundraising. Early stage capacity is limited, and late stage returns should be muted where valuations rest on successive rounds rather than market prices.

• Private credit's role in the next downturn: Buyout targets are 10 times more likely to file for bankruptcy within a decade than comparable companies. With private credit financing half of deals and covenants largely gone, the next stress test will run through nonbank lenders.

The Wrap

Private equity delivered on the terms of the last regime, and the terms have changed before the industry has cleared the consequences. Record dry powder, a nine year exit backlog, higher rates, and fading persistence mean future returns depend on operating work and honest valuation rather than financial engineering. The push into 401(k) plans will bring new capital and new scrutiny of liquidity, fees, adverse selection, and marks that were never designed for daily pricing. For technology providers the opportunity sits where the strain is: mark transparency across continuation funds and secondaries, liquidity modeling for semi liquid retail vehicles, and cross asset views that let allocators see private credit, buyout, and venture as one leveraged balance sheet rather than three line items.
