Expected Returns in Private Equities and Infrastructure: Capital Market Assumptions 2026
We introduce 2026 Capital Market Assumptions (CMAs) utilising infraMetrics® and privateMetrics®, including the flagship infra300® and private2000® indices. Our capital market assumptions tool and Excel add-in allow one to download the monthly prices across indices, compute returns, volatility, and correlation across asset classes. The tool allows for building optimal asset allocation using the inputs obtained from privateMetrics and infraMetrics, combined with public markets data. The indices are comprised of private companies, built with representative industry and geographic allocations. This represents an improvement over applying arbitrary premiums to listed markets or using appraisal NAV based indices, which can produce misleading CMA inputs due to inaccurate return, volatility, and correlation estimates.
Private Infrastructure CMAs Highlights
Median expected returns and volatility1 for the infra3002 index are 11.31% and 8.84%, respectively. For the infra100 Global index, expected returns and volatility are 11.75% and 12.15%, respectively. Finally, for the infraGreen index, expected returns and volatility are 10.15% and 7.95%. Expected returns across the three indices are in line with the total annualized returns observed over the past 3 years. During this period, asset prices have adapted to a changing interest rate regime, with higher bond yields. Additionally, we provide expected returns at the Industrial level.
Private Equities CMAs Highlights
For private equities, we provide discount rates for the private2000 index and for the Activity Class (sector) level of the index. Median expected return and volatility for the private2000 index is 12.2% and 17.3%3, respectively. Recent private equities returns have been weak. Nonetheless, current expected returns reflect appropriate compensation for risk taken in the private equities market, assuming assets are marked to market. Moreover, by providing discount rates at the sector level, we enable a more granular assessment of return expectations across sectors.
