An employer’s 401(k) menu could look very different within a few years, and the asset management industry is eager to explain why.
President Donald Trump signed Executive Order 14330 in August 2025, directing federal agencies to smooth the regulatory path for alternative investments inside workplace retirement plans.
The order covers private equity, cryptocurrency, real estate, and other categories that have historically been unavailable in most 401(k) and 403(b) accounts.
The Department of Labor followed with a proposed safe harbor rule in March 2026, and firms like BlackRock began building PE-infused products for retirement accounts.
Vanguard, one of the largest retirement-focused asset managers, published an investor-facing allocation framework on Aug. 14, 2026, that tells a far more cautious story.
The firm’s recommended private equity range starts at 0%, targets ultra-high-net-worth investors, and warns of restricted liquidity and elevated costs.
Vanguard’s private equity allocation starts at zero and caps well below industry hype
The firm’s framework recommends a private equity allocation from 0% to 40% of total equity exposure, not overall portfolio allocation, Vanguard specified.
A 10% allocation of the equity sleeve in a traditional 60/40 portfolio translates to roughly 6% of total assets, a fraction of what headlines suggest.
Vanguard lays out four tiers, and the first is explicitly zero for people with higher liquidity needs, shorter time horizons, or discomfort with uneven outcomes.
Investors comfortable locking up capital for extended periods while accepting irregular and unpredictable cash flows occupy the upper end of that allocation range.
The firm’s disclosure adds that private equity remains generally available only to ultra-high-net-worth investors who meet accredited investor or qualified purchaser thresholds.
An April 2026 Vanguard research paper raised a fundamental concern about whether the average private equity fund compensates investors for the illiquidity and fees it demands.
A $3.8 trillion exit backlog fuels the push for retirement money
The private equity industry’s own financial picture adds context to Vanguard’s caution and underscores what is driving the sudden interest in retirement plan assets.
Private equity firms globally are holding roughly 32,000 unsold portfolio companies valued at about $3.8 trillion, Bain & Company’s 2026 report found.

- Vanguard’s new 401(k) numbers have good news for Millennials
- Vanguard doubles down on U.S. stocks with 4 new ETFs
- Vanguard sends urgent warning on major 401(k) growing problem
Average holding periods at exit have stretched to roughly seven years, compared with five to six years from 2010 to 2021, the report confirmed.
Distributions to private equity investors have remained below 15% of net asset value for four consecutive years, the longest such stretch on record, Bain noted.
“The push for private assets into retirement plans is entirely supply-driven. Sponsors, advisers, and participants are not asking for it at all,” said George Webb, chief executive officer of advice firm Pension & Wealth Management Advisors.
Defined-contribution plan assets totaled $13.8 trillion as of the first quarter of 2026, including $9.9 trillion held in 401(k) plans, Investment Company Institute data showed.
For an industry struggling to return capital to existing investors, paycheck deductions flowing automatically into 401(k) accounts create a stream no voluntary pool can match.
How opaque pricing and layered fees affect everyday 401(k) savers
Publicly traded stocks price continuously throughout each session, but private equity holdings are valued quarterly or less frequently based on fund manager estimates, Vanguard’s framework noted.
That valuation gap can mask true losses for months, leaving your account balance appearing stable while underlying holdings may already be declining in market terms.
More than a third of workers (34%) have taken a loan or early withdrawal from a 401(k) or similar plan, the Transamerica Institute’s 2025 survey found.
Private equity holdings, which typically cannot be redeemed on demand, could create complications that do not exist with publicly traded investments in those situations.
Alicia Munnell, a MarketWatch columnist and senior advisor of the Center for Retirement Research at Boston College, warned that private equity’s valuation structure introduces risks that retirement savers are not equipped to navigate.
…private equity is not a transparent investment. Moreover, it takes years for returns to be realized, and participants who leave early will have paid higher fees for nothing. Private equity simply adds unnecessary risk to retirement savings.
Robert Morris, CEO of Olympus Partners, warned that layered fees inside retail private equity products make it unlikely that net returns will outpace an index fund.
Morris, in a warning to Olympus investors cited in a Better Markets analysis, said routing 401(k) savings into private markets “bodes to be the successor to the 2008 mortgage crisis.”
The Private Equity Stakeholder Project reviewed 15 large private equity evergreen funds marketed to retail investors and found they delivered a median return of 11.97% in 2025.
That was roughly half the 22.34% return of the MSCI ACWI Index, while median expenses reached 3.76% across the funds.
Vanguard’s conclusions matter for 401(k) savers reviewing private equity options
Vanguard’s midyear private equity research from July 2026 reinforced a conclusion with direct relevance to this debate.
Without consistent access to top-tier fund managers and broad diversification across strategies, the premium over public stocks is not reliably capturable, the analysts wrote.
The executive order opened a regulatory pathway, but cost structures, liquidity constraints, and valuation opacity flagged in Vanguard’s framework remain unchanged for everyday retirement savers.
For workers building retirement savings through these plans, the question is whether their employers will apply the selectivity that Vanguard demands for its wealthiest clients.
