If you have a 401(k), you need to know about a rule change the Department of Labor is trying to push through—and the comment deadline is June 1st, which means you have about 24 hours to weigh in if this bothers you.

Here's what's happening: the DOL has proposed a rule (Docket EBSA-2026-0166-0001) that would make it easier for your employer to stuff private equity and private credit into your retirement account. Specifically, it creates a legal "safe harbor" for plan managers who add these alternative assets to target-date funds and default 401(k) lineups.

Translation: if your company checks off a basic procedural list when choosing these funds, they get a "presumption of prudence" under ERISA—the law that's supposed to protect your retirement savings. That means when the underlying assets tank or the fees eat your returns alive, it's going to be nearly impossible to sue them for breach of fiduciary duty.

Why is this a problem? Three reasons: liquidity, fees, and opacity.

Private equity is illiquid. You can't just sell it when the market tanks or you need cash. That's fine if you're a pension fund with a 30-year time horizon, but most 401(k) participants expect to access their money on reasonable terms. Target-date funds are supposed to get more conservative as you approach retirement, not less liquid.

The fees are brutal. Private equity funds charge management fees and carried interest—often 2% annually plus 20% of profits. Compare that to a Vanguard index fund charging 0.04%. Over 30 years, that difference is catastrophic. And because private equity valuations are self-reported and updated quarterly (not daily, like stocks), it's easy to smooth over bad performance until it's too late.

And here's the kicker: this won't be marketed as "private equity." It'll be baked into target-date funds with names like "Growth 2050" or "Retirement Income Plus." Most people won't even know they own it until they try to rebalance and discover they can't.
