Understanding Private Equity Trends: What HarbourVest’s Q3 2025 Benchmark Data Reveals About Global Investment Performance

Private equity—capital invested in privately owned companies rather than publicly traded stocks—has become a major force in the global financial system over the past several decades. Pension funds, university endowments, sovereign wealth funds, and institutional investors increasingly rely on private equity investments to diversify portfolios and potentially earn higher long-term returns.

In late 2025, global investment firm HarbourVest Partners released updated benchmark data covering private equity performance through the second quarter of 2025 and projections for the third quarter. The report provides insight into how private equity has performed compared with public markets and highlights key sectors and regions driving returns.

For investors, policymakers, and industry observers, the data offers more than just numbers. It helps explain how private equity functions, why its performance patterns differ from public markets, and what current trends may mean for the global economy.

The Growing Importance of Private Equity in Global Finance

Private equity refers to investments made directly into private companies or through buyouts of publicly traded firms that are then delisted from stock exchanges. Unlike stocks traded on public markets, private equity investments are typically long-term and involve active management or restructuring to improve a company’s value.

The modern private equity industry began expanding rapidly in the 1980s and 1990s. Since then, it has evolved into a multi-trillion-dollar global asset class. According to HarbourVest, its benchmark database analyzes more than 64,000 deals involving over $3.7 trillion in invested capital across roughly 3,000 partnerships spanning 45 years.

Private equity’s rise reflects several broader trends:

• Institutional investors seeking higher returns than traditional bonds or stocks.
• Companies staying private longer before pursuing public listings.
• Growing pools of capital managed by specialized investment firms.

Because private companies are not required to publish detailed financial data in the same way public companies are, measuring performance across the industry can be challenging. Benchmark datasets such as HarbourVest’s aim to provide transparency and standardized comparisons.

What the HarbourVest Private Equity Benchmarks Measure

The HarbourVest Private Equity (HV PE) Benchmarks track investment performance across several major categories, including:

• Global buyout funds
• U.S. buyout funds
• European buyout funds
• Global ex-U.S. buyout funds
• U.S. venture capital funds

These benchmarks analyze transaction-level data to estimate how private equity investments are performing relative to major public market indices.

Unlike stock market indices, which update daily, private equity performance is reported with a delay because investments are valued quarterly and underlying firms report results weeks or months after the end of each period. As a result, benchmark projections often provide early indications of market trends before final data becomes available.

The Q3 2025 projections were released alongside updated performance figures through June 30, 2025.

Key Performance Trends in the Latest Benchmark Data

The HarbourVest report highlights several notable patterns in private equity performance during 2025.

First, public markets outperformed private equity over the most recent 12-month period. However, private equity still maintained stronger performance over longer time horizons.

Benchmark Comparison

Benchmark Category	Projected Q3 2025 Return	Trailing 12-Month Return	5-Year Annualized Return	10-Year Annualized Return
Global Buyout	3.8%	9.4%	14.9%	13.7%
U.S. Buyout	3.5%	7.1%	14.8%	14.1%
Global ex-U.S. Buyout	2.8%	12.6%	15.0%	13.3%
Europe Buyout	2.5%	14.6%	15.8%	14.6%
U.S. Venture Capital	2.5%	12.8%	18.7%	16.2%

These figures illustrate a consistent pattern in private markets: short-term results can lag public equities, but longer-term returns often remain competitive or stronger.

For example, global buyout funds produced annualized returns of nearly 15% over five years and more than 13% over ten years. By comparison, the global public equity index MSCI ACWI delivered roughly 10.5% annualized returns over the same ten-year period.

Why Private Equity Often Shows Strong Long-Term Returns

Several structural characteristics explain why private equity may outperform over extended time periods.

1. Active Ownership

Private equity firms typically acquire large stakes or full ownership in companies. This allows them to influence strategic decisions, restructure operations, and pursue growth initiatives.

These interventions can include:

• Management changes
• Operational efficiency programs
• Expansion into new markets
• Strategic acquisitions

Such active involvement contrasts with public market investors, who generally hold minority stakes and have limited influence.

2. Longer Investment Horizons

Private equity funds usually operate on investment cycles lasting seven to ten years. During this period, investors focus on building value gradually rather than reacting to daily market fluctuations.

This longer horizon can provide stability during periods of public market volatility.

3. Access to Emerging Companies

Many high-growth firms remain privately owned for longer than in previous decades. Venture capital and growth equity funds invest in these companies before they reach public markets.

This can provide early exposure to sectors such as:

• Technology
• Healthcare innovation
• Digital infrastructure
• Financial technology

Sector Trends Driving Private Equity Performance

Another key insight from the HarbourVest benchmarks is the role of sector performance.

In the second quarter of 2025, several sectors stood out as outperformers in global private equity portfolios:

• Communication services
• Financial services
• Healthcare

At the same time, other sectors produced more modest results:

• Materials
• Industrials
• Information technology

The energy sector experienced negative returns during that period.

These variations reflect how private equity funds allocate capital across industries based on expected growth potential and market conditions.

For instance, healthcare investments may benefit from long-term demographic trends such as aging populations and rising healthcare demand. Similarly, communication services companies can benefit from expanding digital infrastructure and global connectivity.

Expanding Geographic Coverage in Benchmark Data

One notable development in the latest HarbourVest report is the introduction of new benchmarks covering regions outside the United States.

Two new benchmarks were included:

• Global ex-U.S. Buyout Benchmark
• Europe Buyout Benchmark

The Global ex-U.S. benchmark includes companies headquartered across several regions:

• Europe (approximately 76.7%)
• Asia (15.1%)
• North America outside the United States (4.4%)
• Emerging markets (3.8%)

The European benchmark focuses primarily on companies based in:

• United Kingdom
• Germany
• France
• Other Western and Eastern European countries.

These additions reflect the increasingly global nature of private equity investing. Over the past two decades, deal activity has expanded rapidly across Europe and Asia, as investment firms seek opportunities beyond North America.

Why Short-Term Private Equity Returns Can Lag Public Markets

While private equity often demonstrates strong long-term performance, short-term comparisons with public markets can appear less favorable. Several factors contribute to this difference.

Valuation Timing

Private equity assets are valued quarterly rather than continuously. During periods of rapid stock market growth, public equities can temporarily outperform because their prices update instantly.

Illiquidity

Private equity investments cannot be easily sold on demand. Funds must wait for exit opportunities such as acquisitions or public listings.

Economic Cycles

Economic shocks can temporarily reduce deal activity and slow exits, affecting short-term performance. For example, market volatility and policy uncertainty can delay mergers or initial public offerings.

Despite these factors, private equity performance tends to smooth out over longer periods.

---

Broader Industry Trends Affecting Private Equity

The benchmark report also arrives during a period of significant change in the global private equity industry.

Several trends are shaping investment activity:

Rising Deal Activity

Global private equity deal value reached approximately $1.15 trillion by the third quarter of 2025, with full-year totals expected to approach $1.4 trillion, marking the highest levels since 2021.

This suggests renewed momentum after a slowdown caused by macroeconomic uncertainty in previous years.

Increased Exit Activity

Exit activity—when private equity firms sell investments—also increased during 2025. The number of exits rose about 17% from the second quarter to the third quarter.

Higher exit levels are important because they return capital to investors and allow funds to launch new investment cycles.

Liquidity Pressures

Despite improving conditions, fundraising remains challenging. Institutional investors have faced liquidity constraints due to slower-than-expected distributions in recent years.

As a result, secondary markets—where investors sell stakes in private equity funds—have expanded significantly.

---

Who Is Affected by Private Equity Performance

Private equity returns affect far more than investment firms themselves.

Pension Funds

Many public and corporate pension plans allocate a portion of their portfolios to private equity. Strong performance can help support retirement benefits for millions of workers.

University Endowments

Major universities often invest heavily in private markets. Returns help fund scholarships, research, and campus operations.

Institutional Investors

Insurance companies, sovereign wealth funds, and family offices use private equity to diversify their portfolios.

Businesses and Workers

Private equity investments can influence company operations, employment levels, and strategic direction. In some cases, funds help companies expand and create jobs; in others, restructuring efforts can involve cost reductions.

Because of these impacts, private equity performance has broader economic implications.

---

Challenges Facing the Industry

Despite strong long-term returns, the private equity sector faces several ongoing challenges.

Valuation Transparency

Because private companies do not report financial results publicly, estimating asset values can be complex.

Benchmarking efforts aim to improve transparency, but investors must still rely on periodic reports.

Economic Uncertainty

Interest rate changes, geopolitical tensions, and regulatory shifts can influence deal activity and fundraising.

Higher borrowing costs, for example, may reduce the number of leveraged buyouts.

Regulatory Scrutiny

Governments in several countries have increased oversight of private market investments, particularly regarding disclosure requirements and investor protection.

These policies could shape how funds operate in the future.

What the Latest Data Suggests About the Future

The HarbourVest benchmark report suggests that private equity continues to demonstrate resilience despite short-term fluctuations.

Several developments may shape the next phase of the industry.

Continued Global Expansion

As investment opportunities diversify across regions, private equity firms are likely to increase activity in Europe, Asia, and emerging markets.

Growing Role of Private Wealth

Historically, private equity was accessible primarily to large institutional investors. Increasingly, firms are developing products designed for high-net-worth individuals and private wealth platforms.

Innovation in Investment Structures

New deal structures—such as continuation vehicles and secondary transactions—are becoming more common as funds seek liquidity solutions and longer holding periods for successful assets.

Alignment With Structural Trends

Many private equity investments focus on industries linked to long-term global trends, including:

• Digital transformation
• Healthcare demand
• Energy transition
• Infrastructure development

These sectors could continue to attract capital over the coming decade.

Conclusion

The release of HarbourVest’s Q3 2025 private equity benchmark data offers a detailed snapshot of how private markets are performing during a period of evolving global economic conditions.

Although public equities outperformed private equity over the most recent 12-month period, the benchmarks show that private equity continues to deliver competitive returns over five- and ten-year horizons. Sector performance, regional diversification, and evolving deal activity all play important roles in shaping outcomes.

Beyond financial metrics, these benchmarks also highlight the expanding role of private equity in the global economy. Pension funds, institutional investors, and businesses all depend on the industry’s performance in different ways.

As deal activity rebounds and new investment structures emerge, private equity is likely to remain a significant force in global capital markets. The latest benchmark data provides a valuable lens into how the sector is evolving—and what it may mean for investors and economies in the years ahead.
