DOL Issues Proposed Rule and Safe Harbor Intended to Facilitate the Inclusion of Alternative Assets in 401(k) Plans

Key Takeaways

• DOL proposes safe‑harbor for alternative assets in 401(k) plans
• Six factors guide fiduciary selection of designative investment alternatives
• Fiduciaries gain presumption of prudence if process followed
• Rule expands permissible asset classes, including private equity, digital assets
• Comment period ends 60 days after Federal Register publication

Summary

On March 30, 2026 the U.S. Department of Labor issued a proposed rule that creates a safe‑harbor framework for including alternative assets in designative investment alternatives (DIAs) offered by participant‑directed 401(k) plans. The rule, issued under President Trump’s executive order, clarifies fiduciary duties and lists six non‑exhaustive factors—performance, fees, liquidity, valuation, benchmarks and complexity—that must be considered when selecting a DIA. Fiduciaries who follow the prescribed process receive a presumption of prudence and greater deference in litigation. Comments are due 60 days after publication in the Federal Register.

Pulse Analysis

The Department of Labor’s latest proposal marks a decisive shift in how defined‑contribution plans may approach alternative investments. Prompted by a 2025 executive order, the rule seeks to modernize ERISA’s historically process‑centric prudence standard, which has long limited 401(k) participants to traditional equities and bonds. By codifying a safe‑harbor that emphasizes thorough analysis over hindsight outcomes, the DOL aims to reduce the regulatory uncertainty that has kept many plan sponsors from venturing into private‑equity, real‑estate, commodities, infrastructure and digital‑asset strategies.

Central to the proposal are six analytical factors—performance, fees, liquidity, valuation, benchmarks and complexity—that fiduciaries must evaluate when adding a designative investment alternative. The guidance does not prescribe specific thresholds; instead, it offers a flexible, fact‑based framework that, if adhered to, triggers a presumption of prudence and significant judicial deference. This process‑based shield is designed to mitigate litigation fears, encouraging plan sponsors to broaden their investment menus while still meeting the fiduciary duty of care required under ERISA.

If finalized, the rule could reshape the retirement‑plan landscape, creating a new distribution channel for alternative‑asset managers and expanding diversification options for millions of workers. Asset managers will likely develop DIA products tailored to the six‑factor rubric, emphasizing transparent valuation methods and appropriate liquidity provisions. Plan sponsors must monitor the 60‑day comment window and prepare to adjust governance policies accordingly. Early adopters could gain a competitive edge by offering innovative, compliant alternatives that enhance participants’ long‑term risk‑adjusted returns.
