New Federal Rules May Open Retirement Accounts to Riskier Private Investments
Washington, Thursday, 20 August 2026.
Proposed administration changes could bring high-risk private equity into America’s $10 trillion 401(k) market while shielding employers from worker lawsuits over severe plan losses.
Regulatory Rollback Proposed for Retirement Plans
The Trump administration is preparing a significant regulatory rollback designed to loosen restrictions on retirement investment options, a move that could allow plan sponsors to include less-regulated, potentially higher-risk assets in standard portfolios [1]. Wall Street firms are aggressively lobbying for access to the funds held in private 401(k) accounts across the United States, seeking a larger share of the market [1][4]. The proposed changes would permit assets such as private equity and hedge funds to be included in retirement portfolios, sparking a debate between industry proponents seeking higher yields and critics concerned about increased risk for individual savers [1]. This strategic shift follows an executive order issued by President Trump in August 2025, which called for new rules to reduce what was termed regulatory overreach and lawsuits filed by opportunistic trial lawyers regarding 401(k) investment options [1].
Enforcement and Leadership Changes
The Department of Labor, led by appointee Daniel Aronowitz, is driving these changes; Aronowitz previously operated a firm specializing in protecting large companies against employee lawsuits, a sector that stands to benefit from the proposed rule shifts [1]. In April 2026, the Employee Benefits Security Administration (EBSA) released a bulletin updating enforcement priorities, mandating that staff obtain Aronowitz’s approval for major enforcement actions [1]. The bulletin instructs investigators to avoid cases that second-guess process-based fiduciary judgments, effectively creating a safe harbor for employers if they follow a specific, documented process [1]. Ali Khawar, a former senior official at the Department of Labor, criticized the move, stating, “What they have done is lower the standard for everything” [1][2].
Retirement Market Scale
As of March 31, 2026, total US retirement assets were $47.6 trillion, representing a decrease from the $49.1 trillion reported in total retirement assets as of Q4 2025 [1][3]. The percentage change in total retirement assets between Q4 2025 and Q1 2026 is calculated as -3.055 [1][3]. Within this market, 401(k) assets totaled $9.9 trillion as of March 31, 2026, with 58% of those assets managed by mutual funds [3]. The broader US 401(k) market is valued at approximately $10 trillion, making it a significant target for regulatory adjustments aimed at alternative asset integration [1].
Industry Impact and Timeline
Approximately 1,000 companies have already agreed to offer managed accounts with alternative investment options through Empower, the second-largest 401(k) recordkeeper [1]. The administration’s proposed rule predicts that once finalized, plans covering approximately 5 million participants will introduce new or modified target date funds containing alternative investments [1]. A new Department of Labor rule that would shield employers from lawsuits if they follow a documented process for selecting investments is expected to be finalized by the end of 2026 [1]. Tim Hauser, a 34-year veteran of EBSA, noted that the ability of courts and regulators to hold employers accountable for using bad judgment when choosing 401(k) investments is fundamental to the whole system [1].
