How do private asset impact funds perform?

The financial performance of private asset impact funds varies considerably across investment strategies, geographies and market conditions. Private debt, private equity and venture capital funds have different return profiles, risk exposures and investment horizons, making direct comparisons difficult without consistent data.

Tameo's 2025 Private Asset Impact Fund (PAIF) Report examines financial performance across a market representing USD 105.2 billion in assets under management. Its findings point to improving credit risk indicators in 2024 among surveyed funds, alongside rising gross portfolio yields since 2023.

These developments provide useful insight into market conditions, but they should not be interpreted as evidence that impact investing as a whole delivers a particular level of financial return.

What determines financial performance?

Impact investing is defined by the intention to generate positive social or environmental outcomes alongside financial objectives. It does not prescribe a single financial strategy or return target.

Within private markets, financial performance depends on several factors.

• Investment strategy: Private debt funds typically generate income through interest payments and loan repayments. Equity funds depend more heavily on changes in enterprise value, distributions and exits.

• Geographical exposure: Investments in emerging and frontier economies involve different macroeconomic, regulatory, currency and political conditions.

• Portfolio composition: Sector concentration, borrower characteristics, diversification and financing structures influence both expected returns and potential losses.

• Fund structure: Management fees, leverage, hedging policies, liquidity provisions and the distribution of risks between investors affect realised returns.

These differences mean that comparing two funds solely on the basis of reported returns can produce misleading conclusions.

What does the latest PAIF research show?

Tameo's 2025 PAIF Report examines financial performance alongside portfolio quality, fund structures and wider market developments.

Among the findings, credit risk indicators improved in 2024 across the surveyed funds, while gross portfolio yields continued to increase from 2023.

Both developments are relevant to assessing private debt markets. Higher gross yields may support portfolio income, while changes in credit quality can influence loss expectations and the sustainability of returns.

However, gross portfolio yields are not equivalent to net investor returns. Expenses, credit losses, currency movements, fund leverage and other factors must be considered before assessing the ultimate financial performance received by investors.

The report also presents historical return analysis for unleveraged private debt funds, providing a more consistent basis for examining performance over time within a defined strategy.

Why benchmarking requires comparable data

A meaningful financial benchmark should compare investments with sufficiently similar characteristics.

For private asset impact funds, this involves considering the investment instrument, leverage, currency, region, vintage and reporting methodology.

The distinction between gross and net returns is particularly important. So too is the difference between realised cash flows and reported valuations.

Private equity funds, for example, may rely heavily on periodic valuations of investments that have not yet been exited. Private debt strategies may report comparatively regular income, but remain exposed to borrower defaults, recoveries and currency risk.

Neither return profile can be adequately understood through a single headline figure.

A well-designed benchmark allows investors to interpret performance within the relevant strategy and market environment rather than treating all impact funds as interchangeable.

Understanding risk in private asset impact investing

Reported volatility in private markets requires particular care.

Unlike publicly traded securities, private assets are generally not priced continuously. Valuations may be updated periodically, and reported returns can therefore appear smoother than those of investments with daily market prices.

Low observed volatility does not necessarily imply low underlying economic risk.

Credit exposure, liquidity constraints, currency mismatches and concentration risk can remain material, even when reported returns fluctuate relatively little.

Assessing risk consequently requires more than historical return statistics. Portfolio quality, default experience, valuation practices and the resilience of investment structures are essential complements.

Can investors compare impact and conventional investment performance?

Comparison is possible, but it requires careful selection of an appropriate reference group.

A private debt impact fund financing financial institutions in emerging markets cannot automatically be compared with a developed-market investment-grade bond index. Differences in currency, credit quality, liquidity and investment structure may dominate the result.

Similarly, private equity impact funds should be assessed against relevant private-market strategies and investment vintages.

A credible comparison should identify which differences reflect investment performance and which arise from underlying portfolio characteristics.

Financial and impact performance also need to be assessed separately. A fund's achievement of social or environmental outcomes does not by itself establish financial outperformance, just as a strong financial return does not demonstrate positive impact.

From reported returns to investment intelligence

Reliable performance assessment depends on consistent information over time.

Tameo's annual PAIF research contributes to this process through industry-level analysis of fund strategies, financial indicators, portfolios and market developments.

Its Analytics platform complements the research by providing access to proprietary data on more than 950 funds and 500 investment managers, including financial performance information and benchmarks.

The objective is not to reduce impact investing to a single performance figure, but to provide investors with a more reliable basis for screening, comparing and assessing private asset investment opportunities.

For a market characterised by heterogeneous strategies and uneven data availability, the quality of the comparison is often as important as the reported return itself.
