Private Equity Does Not Belong in Your 401(k)

“It is the holy grail,” the man said to me in a solemn tone. He worked in private equity, and he was referring to the 401(k) market. We were just making small talk at a reception, but as it turns out, his view is not uncommon in the industry: Private equity wants access to Americans’ retirement accounts, and is lobbying President-elect Donald Trump’s administration to get it.

I was skeptical about my newfound acquaintance’s metaphor. But I am even more dubious about his assertion that small retail investors should invest their scarce retirement funds in such an opaque and lightly regulated asset class. And almost one-quarter of economists in a recent poll agree with me: Privately owned assets do not belong in 401(k) accounts.

That’s not to say proponents of investing in private markets don’t have their reasons. One has to do with the time horizon. Retirement funds are in it for the long term, and private assets are supposed to offer a higher expected return in exchange for being illiquid. Why shouldn’t long-term individual investors benefit in the same way as long-term institutional investors, such as pension funds or insurance companies? Another has to do with diversification. Private assets are a distinct asset class, and including them in retirement funds would allow them to reduce risk by offering access to a wider variety of assets.

In theory, both of these arguments have merit. But in practice, there are a few problems. First, the risk involved in private assets is not just lack of liquidity. It is lack of transparency.
