Liquidity Is Not Safety

The confusion being corrected

Marc Rowan collapses the public and private distinction onto the axis he says it actually measures: "Public is not safe or risky. Private is not safe or risky. They're both safe or risky. They're just differing degrees of liquidity."¹ Two properties travel together in public markets and are routinely treated as one and the same: liquidity, the ability to exit at a quoted price on demand, and safety, the probability and severity of permanent loss. They are independent. A daily-quoted equity index can lose half its value; an illiquid senior secured loan to a large company can return in full. What public markets supply is a continuous price and an exit, worth a great deal in some situations and nothing at all in others, but that is not the same thing as a reduction in the underlying risk of the asset. The industry's vocabulary has the axes crossed: people say safe when they mean quoted.

The forcing example: a fifty-year account in a daily-liquid fund

The argument bites because of where it gets applied, the retirement system rather than an institutional allocation. Rowan puts a scale on the system he means, twelve to thirteen trillion dollars, held by "people who need retirement money more than anyone else in the world."² Most of that sits in daily-liquid index funds held for fifty years, and roughly ten companies now make up about forty percent of the leading public index, which means, in Rowan's illustration, the United States has "levered the entirety of the retirement system" to a single name, NVIDIA. "So far that's been good. It's not always going to be good."¹ The structure of the observation runs in four steps: the daily liquidity in a fifty-year retirement account is a feature the holder does not actually use; it is not free, since its price is the requirement that the asset be publicly quoted, which restricts the opportunity set to public markets; that restricted opportunity set has become concentrated in a small number of names; and the safe-looking default is therefore a levered, single-factor bet, with the very feature that made it look safe being the feature that caused the concentration.

The compounding argument attached to it

The constructive half of the argument is a claim about long-horizon returns: an extra percentage point of annual return compounded over the decades a saver is actually invested produces something like a fifty to one hundred percent better terminal outcome. The arithmetic is unremarkable and correct in form. The contested part is not the math but the premise that private assets deliver that extra percentage point net of fees, and the broader supporting claim, that "every place that private assets have been added to public portfolios, you've gotten better outcomes," is offered without much specificity.¹ It is worth noting that a one percent edge is a modest number: the case being made for private assets in retirement accounts rests on a small edge compounded over an unusually long horizon, which is exactly the horizon over which fee drag also compounds.

What the argument does not fully address

Illiquidity is not costless either. The claim is that public and private are simply different degrees of the same axis, and then treats the difference as nearly free for a long-horizon holder, but retirement accounts do face real liquidity events, job changes, hardship withdrawals, plan transitions, and the retiree drawdown itself, and a plan-level fund with illiquid holdings inherits the collective version of that problem, which is why semi-liquid vehicles resolve it with redemption gates instead.¹ Marking frequency also does quiet work: an asset priced quarterly by its own manager looks less volatile than the same risk priced every second, so part of the perceived safety of private assets is a measurement artifact rather than a real difference in risk. And the argument is made by a seller of the remedy, since the conclusion is that retirement accounts should hold more of what the speaker's own firm originates, even though the diagnosis of index concentration is independently checkable on its own.

Adjacent

Ranking capital by how long it realistically stays before a covenant or margin call takes it is the same insight applied from the liability side rather than the asset side: Michael Saylor ranks capital by how long it can actually stay in a position, while this concept ranks assets by how long the holder actually needs to be able to exit them. Put together, they describe a single matching problem, where liquidity is only worth paying for when the horizon is genuinely short. Vlad Tenev's push to open private assets to retail investors argues the same underlying fact as one of fairness rather than portfolio construction, exclusion from private markets being inequitable rather than the public default being dangerously concentrated, and both arguments happen to be made by sellers of the same remedy. Uncorrelated Return Streams supplies the requirement the public market can no longer fill on its own, and Ray Dalio's framing of concentration risk is the cleanest statement of why concentration in the safe-looking default is the actual danger rather than a footnote to it.

The liquid side is not fully liquid either

A further inversion strengthens the argument considerably: the public fixed-income liquidity supposedly being given up in exchange for a private allocation largely does not exist either. "There is no liquidity in public fixed income markets," in Rowan's words: market-making capital sits at roughly ten percent of its 2008, pre-financial-crisis level against a bond market three times the size, meaning it can take five days to sell an investment-grade corporate bond even in ordinary conditions, with little to no liquidity expected in a genuine risk-off event. If that holds, the axis being described is not liquid versus illiquid so much as continuously quoted versus not continuously quoted, and a quote is not the same thing as an exit, which is the same point the argument already makes about safety being confused with being quoted, applied one level deeper.²

"Daily liquid seems to me to be the biggest imbalance that we have anywhere in the world," Rowan says. The strongest version of why unused daily liquidity is dangerous rather than merely wasteful is systemic: the United Kingdom's liability-driven investment crisis showed what happens when a shared liquidity assumption is called on collectively, with many holders owning the same AAA and AA-rated risk in the same way and assuming they could sell it to meet a margin call. They could not. Individually true liquidity assumptions can be collectively false, which cuts against a defense the argument needs elsewhere: if the promise of daily liquidity is itself unreliable under stress in public markets, a semi-liquid private vehicle with redemption gates is not obviously worse in kind, only more honest about the tradeoff up front.²
