Fund-Fee Study: 3 Things to Know About What's Driving Fund Fees Down

Asset flows reveal that investors favored lower fund fees in 2018

The amount investors paid to own funds hit a record low in 2018: The asset-weighted average expense ratio for U.S. open-end mutual funds and exchange-traded funds fell to 0.48%, down from 0.51% in 2017.

We estimate that investors saved roughly $5.5 billion in fund expenses last year due to this 6% fee decline, marking the second-largest year-over-year percentage decline since we began tracking asset-weighted average fees in 2000.

Morningstar Research Services’ annual fund-fee study examines fees across U.S. open-end mutual funds and exchange-traded funds. Below, explore some of this year’s key findings on asset flows and the impact of advice on fees.

1. Funds with lower fees are experiencing greater asset flows

The trend of the cheapest funds raking in assets continued in 2018: Funds whose fees ranked within the bottom quintile of their Morningstar Category group saw net inflows of $605 billion in 2018, with around three fourths of that sum directed to passively managed funds. 

At the same time, the remaining 80% of funds (the top four quintiles when sorted by cost) have seen substantial outflows. This group’s flows have been negative for five consecutive years, a trend that continued in 2018 when it witnessed a record $478 billion in outflows.

2. Fund fees are being shaped by the evolving economics of advice 

As the financial advice business continues to evolve, it’s creating a marked impact on flows and fee trends. For instance:

  • Advisor compensation is becoming less reliant on commissions and more so on basis-point fees, which can move advisors to avoid share classes with built-in costs for advice and distribution.
  • The ongoing shift from investment management to planning has led several advisors to redefine the way they advise clients, emphasizing asset allocation over security selection. 

These trends have spurred demand for cheap wide-market exposure, which has favored lower-cost passive funds.

3. How fund fees account for advice

In 2018, Morningstar introduced the service-fee-arrangement data point to its U.S. funds database, which identifies how fund share classes bundle in fees that pay for advice. The three options for this data point include: 

  • Unbundled. In this case, the share class charges investors for investment management and fund-operating expenses only.
  • Semibundled. The share class charges investors for investment management and other operating expenses, and it indirectly charges for sales distribution (in the form of revenue sharing) but doesn't levy 12b-1 fees.
  • Bundled. This indicates that the share class charges investors for investment management and other operating expenses, and levies 12b-1 fees.

The chart below compares these three service-fee arrangements in full. 

When compared with one another, we see that bundled share classes have experienced outflows over the past five years, while semibundled and unbundled share classes have earned steady inflows (as shown on the chart below). This trend aligns with the shift from transaction-driven advice models toward fee-based models.

Overall, we have reason to believe that this trend toward lower fund fees is likely to continue. Today’s investors are paying roughly half as much to own funds as they did in 2000, 40% less than a decade ago, and about 26% less than five years ago. We believe it is unlikely that any of the forces driving declines in fund fees will abate any time soon, so investors may be likely to see fund fees slip even lower in the years to come.
