How Falling Fund Fees Shift Investor Flows Toward Passive Funds
Summary
The article reviews the long decline in mutual fund and ETF expense ratios and links it to investor choices, competition, and changes in financial advice and retirement plans. It distinguishes asset-weighted averages, which reflect where investors put their money, from equal-weighted averages, which describe the typical fund. The reported data show lower costs for passive funds and substantial net flows toward the lowest-cost fifth of funds, much of it into index funds and ETFs.
It also explains why headline fund expenses may understate what investors pay: advisory services and distribution costs can move outside the fund fee and reappear as separate charges. Broad market index funds face especially intense price competition, while the article expects fee pressure to spread further. Its evidence is mainly historical fee and flow data through 2020, with a forecast that costs may continue to fall; it does not establish that low fees alone ensure good investment outcomes or capture each investor’s total costs.
Key ideas
- Asset-weighted expense ratios fall more when investors shift assets toward cheaper funds.
- Passive funds had lower reported fees than active funds, with especially strong declines over time.
- Investor flows into low-cost funds reflect preferences, fee-based advice, and index target-date retirement products.
- Advisory and distribution charges can leave fund expense ratios while remaining part of investors’ total costs.
- Competition has pushed some index funds to zero fees, and the article expects continued downward pressure.
