Washington spent four years saying private equity doesn't fit a 401(k). Reversing it for 90 million savers took twelve months.

The finding, in one paragraph: the largest pool of ordinary Americans' savings — the participant-directed retirement system, more than 90 million people by the executive order's own count — is being opened to the highest-fee, hardest-to-value asset classes in finance, through a regulatory sequence that ran from presidential signature to guidance rescission in five days, and to a proposed liability shield in under eight months.▸ The safest summary of the stakes is the one the government itself wrote twice: in 2021, when the Labor Department said typical plan fiduciaries lack the expertise to evaluate these assets; and in 2026, when its own proposed rule enumerated the six things that can go wrong — fees, liquidity, valuation, benchmarks, performance, and participant comprehension — as the checklist whose completion will now confer legal deference.

Four documents anchor this piece.▸ Executive Order 14330, Democratizing Access to Alternative Assets for 401(k) Investors (August 7, 2025), read directly — including its characterization of prior DOL guidance as "stifling" and litigation as the work of "opportunistic trial lawyers." The Labor Department's December 21, 2021 Supplemental Statement and its August 12, 2025 rescission — DOL's site blocks retrieval, so their language is quoted via the retirement-industry associations' contemporaneous records of the releases. And the March 30, 2026 proposed rule ("Fiduciary Duties in Selecting Designated Investment Alternatives"), classified economically significant at OMB, whose six-factor safe harbor is documented across the legal-bar analyses cited below.

Fees are the one certainty in the debate.▸ Returns are contested — the industry cites institutional private-market performance; critics note appraisal-smoothed valuations flatter both returns and volatility — but the fee gap is contractual: roughly 2 percent of assets annually plus 20 percent of gains, against 0.3 percent for the average 401(k) equity fund and 0.05 percent for an index fund. The arithmetic in the table is illustrative but mechanical: a 10 percent menu allocation at private-equity fee levels adds about 0.17 percentage points of drag to a whole portfolio, every year, compounding across a working lifetime — the same compounding argument that made index funds the default in the first place.

The two positions in this fight were both written by the Department of Labor.▸ The 2021 Supplemental Statement's core finding — issued after reviewing the same 2020 information letter the new EO celebrates — was about capability, not asset quality: plan-level fiduciaries of typical individual-account plans "are not likely suited" to perform the "complex evaluation" private equity requires. The 2026 proposed rule does not refute that finding; it restructures the consequence. Under the safe harbor, a fiduciary who documents a review of six factors — performance history, total-cost transparency, liquidity, valuation methodology, benchmarking, and "an honest assessment of whether participants can reasonably understand what they are investing in" — earns judicial deference. The six factors are, item for item, the risk catalog the 2021 statement worried typical fiduciaries couldn't evaluate. What changed between the two documents is not the risks; it is who bears them when the evaluation is wrong. And the EO's stated premise — that alternatives offer "the very same long-term net benefits... achieved by public pension plans" — is precisely the contested question: pension allocations are negotiated at institutional scale with institutional fee breaks and no daily liquidity requirement, none of which describes a participant-directed account that must price and redeem daily.

The final rule can publish after OMB's minimum 30-day review of the post-comment draft — late 2026 on the current path.▸ Then the market answers: recordkeepers must build daily-valued wrappers around quarterly-valued assets; target-date managers decide whether the safe harbor justifies the litigation risk the EO could not actually extinguish (ERISA's statutory duties remain); and the first generation of products discloses its fees. The measurable outcomes arrive slowly and publicly — in Form 5500 filings, fee disclosures, and, eventually, the performance record of the first cohort. The 2021 statement and the 2026 rule are both on the record; one of them will age well.

EO 14330 was read directly; DOL's 2021 statement, 2025 rescission, and 2026 proposed rule are quoted from DOL releases as preserved in the retirement-industry and legal-bar records cited, DOL's website having blocked direct retrieval. Fee figures are standard industry terms as documented in the rulemaking coverage; the 0.17-point drag is arithmetic, not an official estimate.
