A decade ago, when a private client asked about private equity or infrastructure, the conversation usually started with whether they could get in at all. Today it starts somewhere else entirely. The question is no longer whether to hold these assets, but how to hold them well, and with whom. That shift, from access to execution, is the clearest sign that investing like institutions has moved from the margins of private wealth to its centre.
With this shift, three separate forces have arrived at the same moment: the doors to institutional-style investments have opened, the strategy behind them has a long track record, and the structures that let wealthy individuals and families run money like an institution have matured. Below, we look at each in turn, and at the trade-offs that too many conversations skip over.
For most of the last century, the private investor's default was a portfolio of public shares and bonds, often in the familiar 60/40 split. Large institutions, the great pension funds, insurers, and university endowments, took a different path. They leaned heavily into private markets and real assets, accepted that some of their capital would be locked away for years, and put real effort into choosing a small number of exceptional managers.
One reference point is the endowment model, pioneered at Yale by the late David Swensen. Over more than three decades under his stewardship, the Yale endowment compounded at roughly 13% a year, comfortably ahead of public-market benchmarks, by tilting away from listed stocks and bonds towards private equity, real estate, and other alternatives. Central to the approach is the illiquidity premium: the extra return investors can earn for accepting that they cannot sell an asset quickly. Institutions could afford to lock capital away, so they were paid for doing so.
What has changed is that private investors can increasingly follow the same logic. Not by buying an index, but by building a genuinely diversified portfolio with a meaningful weight in private markets, and the patience to match.
The single biggest change is structural. For years, the best private funds were closed to anyone without tens of millions to commit and the willingness to lock it away for a decade. A new generation of fund structures has lowered those barriers. Evergreen and semi-liquid vehicles, which stay open indefinitely and allow subscriptions and redemptions on a periodic schedule rather than locking capital for the full life of a closed-end fund, now give private investors a far gentler entry point.
Fund managers have noticed where the next wave of capital is coming from, and have built products specifically for the private wealth channel. The flow into private market strategies through advisers and wealth platforms is rising sharply, and is widely projected to keep doing so for years yet. Access, in short, is no longer the bottleneck it was.
Access alone would mean little if the underlying approach did not work. Decades of data now show private markets outperforming their public counterparts over long horizons, though we always remind clients that past performance is never a guarantee, and that the average disguises a very wide spread of outcomes.
The professional verdict is striking. In Mercer's 2025 survey of wealth advisers, 92% already allocated to alternatives and 91% planned to increase that allocation over the following two years.1 When nearly the entire advisory profession is moving in one direction, it reflects a settled conviction rather than a trend.
The third force is the quietest, and often the most important. Investing like an institution takes more than access to the right funds. It takes governance, disciplined due diligence, and the ability to assess the strategies properly. This is where the family office has come into its own, whether a dedicated single-family operation or a shared multi-family arrangement. It gives a private investor the same machinery an institution relies on: a clear investment policy, a considered approach to risk, and the continuity to think in decades rather than quarters.
There is a generational dimension here too. The next generation of wealth holders tends to be markedly more comfortable with private markets and digital assets than their parents were, and as they take a greater hand in family decisions, that comfort is reshaping how portfolios are built.
In practice, investing like an institution rarely means a dramatic overnight switch. It means phasing in, deliberately, over several years.
A private investor might begin by carving out a portion of the portfolio for private equity, accessed through an evergreen fund to keep the commitment manageable. Alongside it, private credit (lending directly to companies rather than buying their shares) can offer income and a different risk profile from listed bonds. Real assets such as property and infrastructure are often added next, prized for the steady, inflation-linked income they can provide across economic cycles.
The point is not to chase every available asset class. It is to build a portfolio whose parts behave differently from one another, so that no single market event dictates the whole. This is where our holistic view takes the stage: we look at a client's entire financial life, their income needs, their time horizon, their plans for the next generation, and shape the allocation around that. As those circumstances change, so does the strategy. The aim is structure and clarity at every stage of the journey, not a fixed template applied regardless of the person.
For all its appeal, the institutional approach carries real costs, and an honest adviser names them plainly.
The first is liquidity. Locking capital away is the source of the illiquidity premium, but it is also a genuine constraint, and even the most sophisticated institutions can be caught out by it. During the 2008 financial crisis, a multitude of investors with heavy illiquid allocations found themselves short of cash, and were forced either to borrow or to sell holdings at distressed prices. More recently, one large property fund spent over a year capping how much investors could withdraw each quarter. Illiquidity is a feature you must be able to afford, not a flaw to be ignored. If you might need the money within a few years, it does not belong in a ten-year fund.
The second is dispersion. In public markets, the gap between an average manager and a good one is fairly narrow. In private markets it is vast. Choosing the right manager is not a refinement of the strategy; it largely is the strategy. That is precisely why the institutional machinery of due diligence and manager selection matters so much, and why access to any investment means little without the judgement to assess it.
The products and structures that let private clients invest like institutions are now widely available. The harder part, and the part that actually drives returns, is the discipline behind them: a clear policy, sober manager selection, a realistic view of liquidity, and the patience to let a long-term strategy do its work. Access without that discipline is where the real risk lies.
