Private markets’ maths problem is really a messaging problem

Private markets don’t have a performance problem. They have an expectations problem. This week’s headlines, from the Wall Street Journal’s take on the “crazy math” of private markets to the Financial Times reporting on redemption pressure and valuation scrutiny, all point in the same direction: the story the industry has told about itself is colliding with how the asset class actually behaves under stress. 

For a decade, that story has been simple and effective: smoother returns, reliable income, institutional access. It fuelled the rise of private credit and helped open the door to wealth and retail capital via semi-liquid structures. 

However, smoother doesn’t mean safer; it often just means slower to reprice. Private assets are illiquid, infrequently valued and model driven. This creates the appearance of stability - until liquidity is tested. When it is, gates appear, redemption queues build and “paper gains” come under scrutiny, not because the assets are broken, but because the messaging was incomplete. 

And yet, the biggest allocators aren’t blinking. The UK pension scheme Nest Corporation is committing £450m to private markets and targeting up to 30% allocation by 2030. Manulife is putting $2bn into private credit. For them, volatility isn’t a red flag - it’s part of the model.

This gap between institutional conviction and broader investor understanding is where the real pressure is building. Private markets are no longer being explained to a narrow group of sophisticated LPs. Now, they are being marketed to a much wider audience, across wealth channels and semi-liquid structures, where expectations are shaped by daily pricing, easy access and comparability with public markets. The language has simplified, and the products have followed. The underlying assets have not.

This tension is now surfacing publicly.

Valuations that once felt comfortably abstract are being questioned. Liquidity terms that sat quietly in documentation are becoming headlines. Narratives built around consistency and resilience are being tested in real time.

None of this weakens the long-term case for private markets. However, it does expose a growing communications gap. The takeaway for asset managers is straightforward: the narrative needs to catch up with the product.

For years, private markets have been sold on what they deliver. Now, there is a greater need to explain how they work. This means being more explicit on valuation approaches, clearer on liquidity constraints, and more disciplined in how stability and income are described. Messaging that leans too heavily on simplicity risks creating confusion when markets turn.

This is ultimately a question of credibility. As private markets become more visible and more widely distributed, scrutiny will follow. The firms that navigate this successfully will not be the ones that avoid difficult conversations, but the ones that address them directly, with clarity, consistency and realism.

Private markets remain a long-term story. However, in a more transparent, more retail-driven environment, how that story is told will matter just as much as the returns themselves.
