Private markets had a distribution problem for most of their history. The returns were attractive and the vehicles were closed — a ten-year lock-up, capital calls at inconvenient moments, and a minimum that ruled out anyone who was not an institution. The individual investor was structurally excluded.
The semi-liquid fund solved that. It holds private assets, accepts money continuously, and offers redemption on a periodic basis, usually quarterly, usually capped at a small percentage of net assets. It has raised an extraordinary amount of money, and it is a genuinely useful innovation. It is also carrying a promise that has not yet had to be kept at scale.
The cap is not a detail, it is the mechanism
The redemption limit is what makes the structure possible. A fund holding illiquid assets cannot honour unlimited withdrawals, so it agrees to buy back a fixed share per quarter and no more. If requests exceed that, everyone is filled pro rata and the rest queues.
That is disclosed clearly and it is not a trick. What is untested is the behaviour of the holders. Almost all of the money currently in these vehicles arrived during a period when nobody needed to leave, from investors who have never experienced the gate operating. An investor who reads "quarterly liquidity" and hears "I can get out" has misread the product, and will discover this at the worst possible time, because the quarter in which the cap binds is by definition the quarter in which many people want their money.
There is a valuation question underneath. Redemptions are paid at net asset value, and NAV for private holdings is an estimate produced periodically by people with a stake in it. If the mark is stale in a falling market, early redeemers are paid at a price the remaining assets cannot support, and the cost lands on whoever stayed. This is the mechanism that makes queues rational: once an investor suspects the mark is high, redeeming first is the correct individual decision, which is precisely the condition that produces a run.
It is also where the secondary market has become the exit matters, because secondaries are where private marks meet an actual bid — and for several fund vintages that bid has come in below carrying value.
The structural pressure is that this money is retail and increasingly sits inside retirement accounts, as alternative assets creep into retirement menus. An institution that hits a gate is annoyed and has a treasury team. A household that hits one may have been counting on the money, and has no alternative source.
None of this makes the vehicles unsound. They are a reasonable way to hold assets a household could not otherwise access, provided the holding is genuinely long-term money and the gate is understood as the ordinary operation of the product rather than a failure of it. The risk is not the structure. It is the gap between what the document says and what the buyer heard, and that gap gets measured in a quarter nobody has scheduled.
