Private markets: moving from access to outcomes

In our latest Global Asset Owner Barometer research with large asset owners, 96% of the respondents’ portfolios include private-market exposure, up from 80% in 2025 and 20% of asset owners are intending to increase their commitments in private markets over the next 12 months.

At the same time capability and selectivity are key. The same research shows over a quarter of large asset owners (27.7%) anticipate gaps in their ability to underwrite or conduct due diligence and 20.7% foresee gaps in their direct or indirect capabilities within the next three years.

Strategies and investment areas

What do I need to consider when investing in private markets?

First, you need to decide how much of your total portfolio you’re comfortable allocating to less liquid, long-term investments. You should consider your ongoing cash flow requirements and recognize that the capital you commit to private market investments will be invested incrementally over time, and you will need to have cash available when a capital call arrives.

In private markets, the difference between the returns made by the best and worst performing asset managers can be considerable and are often much wider than in traditional asset classes. We believe capturing the most attractive opportunities requires active sourcing, research and access to high-quality, specialist private markets asset managers. Asset manager selection is where you need to choose the right collaborator who understands your needs and has the depth of experience to help you implement a private markets solution.

Due to the capital-intensive nature of private market investments, most asset managers focus on a small number of assets in their portfolios. For example, in private equity or infrastructure, there may be as few as ten underlying assets in an individual manager’s fund. Allocating to a range of private markets strategies can help diversify your portfolio by number of underlying investments, manager, strategy, geography and vintage year.

Most private markets managers offer their investment strategies through closed-end fund structures and raise capital infrequently, with limited capacity. You need to put a robust commitment plan in place to build up and maintain your exposure at your desired target level over time.

Once you’ve implemented your strategy, we believe it is vital to monitor underlying investments and ensure you are comfortable that your portfolio is on the right track. This is called good governance. It’s particularly critical to assess your liquidity budget and commitment plan on an ongoing basis. This helps keep your strategy and target allocation in line with your desired position.

Operational, legal and tax due diligence is crucial, given that investment structures are in limited liquidity vehicles, with little option to action any changes after your initial commitment. These areas require careful consideration and rigorous assessment before committing to any private market investments.
