Fidelity, Schwab and the Price of ZeroNarrow moat
BlackRock (BLK) — moat facet
Rivals who manufacture funds as a marketing expense for a business that earns its money somewhere else.
Fidelity and Schwab compete with BlackRock in funds while making their money somewhere else — on brokerage, advice, custody, and the interest earned on client cash. That changes what a fund is for.
For BlackRock, a fund is the product and the fee is the revenue. For a brokerage, a fund can be a customer-acquisition cost. Charging zero for an index fund is a rational marketing expense if it brings an account onto the platform, where the economics are earned. Fidelity has run index funds at a zero management fee for years on exactly this logic.
The competitive consequence is a permanent floor of nothing under index pricing, set by firms who are indifferent to the fund's own profitability. BlackRock cannot match that arithmetic because it has no second business to subsidise the first — which is precisely why it has spent so much effort building one in technology and alternatives.
The offsetting fact is distribution. These firms are enormous distributors as well as manufacturers, and BlackRock's funds are on their platforms and in their advisory programmes. A brokerage that offers its clients open architecture makes money from BlackRock's products through trading, custody and advice, which makes the relationship mostly commercial rather than adversarial.
It is rated narrow because the threat is asymmetric in an awkward way. These firms cannot take BlackRock's institutional business and are not really trying. They dominate the direct retail channel BlackRock does not have — the firm serves retail investors principally through intermediaries1, which is 10% of its long-term assets and 25% of its long-term base fees2, they set the price at zero in the products that channel buys, and they control an approved list on which BlackRock is a guest.
The zero-fee funds have existed for years and have not taken BlackRock's institutional or adviser business. They continue to set the floor under retail index pricing, and neither side of that has moved recently.
Zero-fee index funds set a floor BlackRock cannot go below. Revenue growing this fast shows the product mix outrunning the fee pressure; slower revenue growth than asset growth would show the floor biting.
