# Where the margin actually lands: mapping value capture across the chain
A retail investor in Ohio buys a passive S&P 500 fund charging 0.03% a year. On a $10,000 holding, that is $3 annually. Now watch that $3 travel. By the time it settles, it has been split between at least four businesses, and the asset manager whose name is on the fund keeps surprisingly little of it. Understanding who takes what, and why, is the fastest way to see where power actually sits in asset and wealth management.
A client's fee passes through a value chain. Each link performs a function and takes a cut:
The fee the client sees is the expense ratio (the annual percentage a fund charges, also called the total expense ratio or TER in Europe). But that headline fee is only part of the story, because distribution is often paid separately.
Take an ultra-cheap passive equity fund at 3bp ($3 on $10,000). Rough allocation, using publicly discussed industry economics (illustrative estimates, not a specific fund's disclosed breakdown):
| Link | Approx share of the 3bp | Dollars on $10,000 |
|---|---|---|
| Asset manager (net) | ~1.0 to 1.5bp | $1.00 to $1.50 |
| Index licence fee | ~0.5 to 1.0bp | $0.50 to $1.00 |
| Custody and admin | ~0.3 to 0.5bp | $0.30 to $0.50 |
| Distribution | often $0 here | $0 |
The striking part: on a passive product, the index provider can capture a share comparable to what the manager keeps. S&P, MSCI and FTSE Russell run high-margin licensing businesses precisely because their benchmarks are effectively standards. A manager cannot sell "the S&P 500 fund" without paying S&P. That is structural power.
The manager's tiny slice is why passive is a scale game. At 1bp net on $3 trillion of assets, you earn $300 million. At 1bp on $3 billion, you earn $300,000. This is the entire strategic logic behind Vanguard and BlackRock's iShares: volume, not margin.
Now flip to a typical active mutual fund in a US wealth channel. Headline fee might be 0.75% (75bp). But look who wins.
For decades, US funds paid a 12b-1 fee (named after the SEC rule authorizing it), a slice of the expense ratio, often around 25bp, routed to distributors and advisers for selling and servicing. Add revenue sharing (payments from the fund company to the platform for shelf space), and the distributor's take can rival or exceed the manager's.
Concretely: of 75bp, the manager might net 35 to 45bp for actual portfolio management, while 25 to 35bp flows to distribution and platform economics. The person who controls the client relationship extracts a toll.
This is the core power dynamic of the sector: whoever owns the client owns pricing. Fidelity and Schwab can offer zero-fee funds and still profit, because they monetize the surrounding relationship (cash sweep, securities lending, advice fees, order flow economics). The fund fee is a loss leader.
In the EU and UK, regulators attacked this directly. The RDR (Retail Distribution Review, UK, 2013) banned commissions paid by fund managers to independent advisers. MiFID II (Markets in Financial Instruments Directive II, EU, in force 2018) tightened inducement rules across Europe. The intent: stop hidden distributor payments that biased advice.
The effect on value capture was real. Advisers moved to explicit fees paid by the client (say 1% a year for advice), and fund managers could no longer bundle distribution into the product fee as easily. Value did not disappear, it became visible and unbundled. A UK client now often sees three lines: the fund (maybe 0.20%), the platform (maybe 0.25%), and the adviser (maybe 0.75%). Same total cost, clearer split. The FCA's Retail Distribution Review pages document the original aims.
Two supplier groups punch above their weight.
Index providers. S&P Dow Jones Indices, MSCI and FTSE Russell form a near-oligopoly in flagship benchmarks. Their margins are high because switching is painful: an ETF that tracks the S&P 500 cannot casually re-badge to a rival index without confusing investors and triggering tracking differences. MSCI's emerging-markets and ESG indices are similarly entrenched. As passive assets grew, so did the toll these providers collect. They are the arms dealers of the index wars.
Data and analytics. Bloomberg terminals, MSCI's risk models, and increasingly ratings and ESG data feeds sit as fixed costs every manager pays. These do not appear in the client's expense ratio directly, but they eat the manager's slice.
Custodians are the opposite: enormous scale, thin margins per dollar, and fierce competition. BNY, State Street and Northern Trust compete hard on basis points for custody, then try to earn more from securities lending (lending out portfolio holdings to short-sellers for a fee) and foreign-exchange execution. Custody is a volume utility; the extras are where the margin hides.
The passive giants (BlackRock's iShares, Vanguard, State Street's SPDR) dominate index products and compress fees toward zero. Vanguard's mutual-ownership structure lets it treat low fees as the strategy, not a sacrifice.
Challengers fight where fees cannot go lower:
The pattern: fee pressure is brutal on plain products, and the survivors either win on scale (passive) or escape to where scale does not commoditize them (private markets, advice, alternatives).

A client invests $1,000,000 through a UK adviser into a passive global equity portfolio.
Now split the fund's $2,000:
So of $12,000 the client pays, the asset manager keeps roughly $1,000, about 8%. The adviser and platform together take $10,000, over 80%. (Figures illustrative, based on typical 2026 UK fee ranges.)
That single calculation is the whole lesson: on mainstream products, the client relationship (distribution and advice) captures the lion's share, the manufacturer captures a sliver, and the supplier (index) quietly takes a reliable toll.
