Where do conflicts of interest hide in a fee structure?

Educational content, not legal or compliance advice. Permitted fee models differ sharply by jurisdiction — some of the arrangements below are banned outright in certain markets and routine in others.

A conflict of interest is any situation in which your own interest, your firm's, or another client's could reasonably influence a judgement you owe to a client. Note the word could. A conflict is a structural fact, not an accusation: it exists the moment the incentive exists, whether or not anyone acts on it.

This matters because the naive model of misconduct — bad people doing bad things — explains almost none of the real damage. The reliable producer of poor outcomes is good people inside bad incentives, each making individually defensible decisions that happen to lean, consistently, in the same profitable direction.

The fee map

Every compensation model rewards a behaviour. Read each one by asking what it pays you to do.

• Commission per transaction → rewards activity. Its failure mode is churning: a portfolio that is always being improved.
• Percentage of assets under management → rewards gathering and keeping assets. Better aligned on performance, but quietly hostile to any advice that shrinks the pot — paying off a mortgage, funding a business, buying an annuity, giving to family.
• Flat fee or hourly → rewards billable time. The least conflicted on product selection; not conflict-free.
• Trail or distribution commissions → rewards selecting the product that pays, which is a different question from the one the client asked.
• Performance fees → reward asymmetric risk: you share the upside and not the downside. Hence high-water marks and hurdle rates, which exist specifically to blunt this.
• Proprietary products → the firm earns on advice and on manufacture. The temptation is structural and permanent.
• Bundled research and order-flow arrangements → the cost is paid out of the client's execution rather than the firm's profit and loss, which makes it invisible on any invoice.
• Sales targets, revenue shares, referral fees → the conflict sits inside the organisation chart, where the client cannot see it at all.

The same portfolio, three prices

A €300,000 portfolio, rebalanced eight times a year, roughly €30,000 traded each time.

• Commission model at 1% per trade: €300 × 8 = €2,400 a year — 0.8% — and every one of those eight rebalances was individually justifiable.
• AUM model at 0.5%: €1,500 a year, with no reward for trading and a mild reward for discouraging withdrawals.
• Flat fee: €2,000 a year, unchanged whether the client trades, holds, or is advised to spend the money on something else entirely.

Three sets of incentives, three different portfolios likely to result — from advisers of identical honesty.

The test worth memorising

For any fee arrangement, yours or someone else's, ask two questions:

1. Whose behaviour does this fee reward?
2. What would this fee make me want to do that the client would not want?

Then, as a client: who pays you, and for what? An adviser who cannot answer that in one clear sentence has told you something important.

What to do with a conflict you have found

The hierarchy — developed in the next lesson — runs avoid, then mitigate, then disclose. Avoiding means declining the arrangement or the mandate. Mitigating means structural separation: independent review of the recommendation, removing the person's exposure to the payment, capping or standardising compensation across products. Disclosure comes last, and it is the weakest of the three.

In the data

One layer of this is published for every fund: its own annual fee. An index fund and an actively managed one:

The fee line is the fund's charge and nothing else. The platform's cut, the adviser's trail and any revenue shared between them, which are what this lesson is about, sit in no fund's published figures; they are in the platform's and the adviser's own documents, or nowhere a client will look.

Try it now

1. Find out exactly how every intermediary you use is paid — platform, fund, broker, adviser. Write one sentence each: who pays them, for what behaviour.
2. Take your own work, in any field. Name one incentive in it that could reasonably bend a judgement someone relies on you for. Everyone has one; the exercise fails if you find none.
3. Compare the ongoing charge of two funds: the expense ratio line in each record below. Then work out who receives the difference.
