ERISA Safe Harbor and the 401(k) Retailization Frontier

The expansion of private credit is entering its most consequential growth phase yet: the retailization of direct lending through ordinary Americans' retirement savings. This transition is being accelerated by landmark federal policy shifts and a highly anticipated Supreme Court case.

Federal Policy Shifts: Executive Order 14330 and the DoL Rule

Historically, employer-sponsored defined contribution plans (such as 401(k) plans) have had virtually zero exposure to unlisted alternative assets, consisting instead of liquid mutual funds and broad index funds.

On August 7, 2025, President Trump signed Executive Order 14330, titled "Democratizing Access to Alternative Assets for 401(k) Investors," declaring it the official policy of the United States that retirement plan participants should have access to alternative assets, including private credit, private equity, digital assets, and infrastructure.

To implement the order, the Department of Labor (DoL) published its proposed regulation, "Fiduciary Duties in Selecting Designated Investment Alternatives," on March 31, 2026. The rule is "asset-class neutral" and establishes a process-based safe harbor under ERISA. Under this safe harbor, a plan fiduciary is presumed to have satisfied the ERISA duty of prudence if they thoroughly evaluate six factors: performance, fees, liquidity, valuation, benchmarks, and complexity.

The safe harbor is specifically designed to shift the burden of proof in fiduciary litigation from plan sponsors to plaintiffs. The DoL estimates that, if finalized, the rule will result in approximately $178 billion in retirement assets across 4.5 million participants being allocated to alternative investments, primarily embedded within target-date funds (TDFs) via automatic enrollment.

Political Backlash

Critics have strongly condemned the timing of the rule. Senator Elizabeth Warren characterized the regulatory push as reckless, criticizing the administration's decision to channel volatile, illiquid assets into individual 401(k) plans precisely as "cracks emerge in the private credit market" and private credit funds are forced to gate withdrawals.

The Supreme Court and Anderson v. Intel Corporation

The legal viability of this retailization push will likely be determined by the U.S. Supreme Court. In January 2026, the Supreme Court granted certiorari in Anderson v. Intel Corporation Investment Policy Committee.

In Anderson, participants in Intel's retirement plans alleged that fiduciaries breached their ERISA duties by allocating significant funds to hedge funds and alternative investments that underperformed public markets. The Ninth Circuit dismissed the suit, holding that plaintiffs must identify a "meaningful benchmark" (a comparable public market alternative) to plead a fiduciary breach.

If the Supreme Court rejects the Ninth Circuit's "meaningful benchmark" requirement, fiduciaries who allocate 401(k) assets to underperforming or gated private credit vehicles will face a significantly higher risk of class action litigation. If the Court upholds the requirement, it will create a substantial legal shield for retirement plan administrators.

"The proposed rule establishes a process-based safe harbor under which an ERISA fiduciary selecting designated investment alternatives for a participant-directed defined contribution plan will be presumed to have satisfied the duty of prudence if the fiduciary objectively, thoroughly, and analytically evaluates six factors... The DoL estimated that if finalized, the rule could result in approximately $178 billion in retirement assets across 4.5 million participants being allocated to alternative investments." — Quinn Emanuel Client Alert: Private Credit Under Stress - Emerging Litigation Risks
