(1) The Scale and Structural Challenges of the U.S. Pension System

The U.S. pension system is vast and complex, and is the largest private retirement savings market in the world. As of 2025, the total asset size of retirement plans governed by the Employee Retirement Income Security Act (ERISA) reaches as much as $42 trillion, covering multiple forms such as employer-sponsored defined contribution plans (DC plans), defined benefit plans (DB plans), and individual retirement accounts (IRAs). Among these, target-date funds (TDFs) have become the default investment option for the vast majority of plans, playing the role of a qualified default investment alternative (QDIA) in about 94% of 401(k) plans. At the end of 2024, 67% of participants invested their funds into professionally managed asset-allocation strategies, with 60% investing in a single target-date fund and 7% investing in managed accounts.
