DOL plan to let 401(k)s hold crypto and private funds could unlock trillions in new demand while triggering sharp warnings over fees, volatility and risk.

The U.S. Department of Labor (DOL) has proposed new rules that would allow 401(k) retirement plans to invest in alternative assets ranging from private equity and private credit to cryptocurrencies, potentially opening the $12.5 trillion defined contribution market to some of Wall Street’s riskiest products. The draft guidance, published Monday, seeks to “clarify how trustees can add alternative assets” into 401(k)s, offering fiduciaries a roadmap and legal protection if they document rigorous reviews of performance, fee structures and liquidity before adding such options. The proposal implements an executive order signed by President Donald Trump last summer that directed regulators to expand access to alternatives in retirement accounts, including digital assets such as Bitcoin and Ethereum.

Under the proposed framework, plan sponsors would not be required to offer crypto or private funds, but those that do would need to demonstrate that products meet “prudence” standards around diversification, valuation, redemption terms and participant understanding. Reuters reported that DOL officials emphasized the move “will not open the floodgates for private equity, private credit or crypto funds,” framing the rule instead as a way to remove blanket prohibitions and replace them with case‑by‑case analysis. The department opened a 60‑day public comment period that will run through late May, after which it can finalize, amend or withdraw the rule.

Private equity stocks jump on $14T retirement opportunity

Public markets quickly reacted to the prospect of 401(k) money flowing into alternative managers. Yahoo Finance said shares of Apollo Global Management, Blackstone and KKR climbed between 4% and 5% on Monday, reversing part of the 20%‑plus drawdowns they had suffered earlier in 2026 as fundraising slowed. In a separate analysis, Invezz estimated that the rule could “open a $14 trillion opportunity” for firms like Blackstone and Carlyle, pointing to the sheer size of U.S. defined contribution assets.finance.

While crypto markets only moved modestly — Yahoo noted that Bitcoin (BTC) rose about 1% toward the mid‑$60,000s and Ethereum gained just over 2% after the announcement — the proposal formalizes what had previously been a grey area for plan sponsors around digital assets. A previous Reuters feature on Trump’s 401(k) order warned that opening retirement accounts to crypto and private markets “introduces a new level of risk for everyday investors, who may not fully grasp these complexities,” quoting Allvue Systems executive Phila Hanson on the likelihood of “increased fees” and the need for “careful consideration.”

Warren warns workers could “lose big”

The loudest political critic so far has been Senator Elizabeth Warren. In a letter obtained by CNBC, Warren argued that “for the majority of Americans, their 401(k) serves as a crucial support for retirement stability, not a risk‑laden playground,” and warned that “introducing crypto into American retirement accounts could lead to significant financial losses for workers and their families.”

Warren pointed to research from the U.S. Government Accountability Office that found crypto assets have “unique volatility” and lack reliable methods for forecasting returns, highlighting how Bitcoin’s price swung from more than $126,000 at its October 2025 peak to roughly $70,000 by early February 2026. She also cited estimates from the Center for American Progress that President Trump and his family booked around $12 billion in crypto‑related gains in the year after his 2024 reelection, arguing there is “no basis to expect that permitting plans to offer these alternative investments will yield better results for participants” given their high fees and drawdown risk.finance.

In a previous crypto.news story on South Korea’s own effort to widen access to digital assets in retirement‑style products, regulators similarly stressed the need for guardrails around stablecoins and high‑risk tokens, suggesting that even as jurisdictions race to modernize savings systems, the fight over how far to go with crypto exposure has only just begun. Another story explored how U.S. exchange‑traded funds have already brought Bitcoin exposure into IRAs and brokerage accounts, previewing many of the same diversification versus volatility debates now playing out over 401(k)s. A third story on institutional portfolio construction highlighted how pensions and endowments typically cap crypto at low single‑digit allocations, a benchmark that could shape how aggressively plan sponsors embrace the DOL’s proposal if it becomes law.
