Fiduciary vs. suitability, the standard that determines whose interests come first

"Financial advisor" is not a protected title. Anyone can use it. Two people who both call themselves financial advisors can operate under fundamentally different legal standards, one requiring them to act in your best interest, the other only requiring that their recommendations be "suitable" for you.

This distinction is not academic. It determines what recommendations you receive and what conflicts of interest your advisor is allowed to have.

The fiduciary standard

A fiduciary is legally obligated to act in the client's best interest. This means:

• Recommending what is best for the client, not what earns the highest commission
• Disclosing all material conflicts of interest
• Avoiding conflicts where possible, managing them where not
• Keeping client information confidential

Registered investment advisors (RIAs), firms and individuals registered with the SEC or state securities regulators to provide investment advice, are held to the fiduciary standard under the Investment Advisers Act of 1940.

Certified Financial Planners (CFPs) are required by their certification body to act as fiduciaries when providing financial planning services.

The suitability standard

Broker-dealers and their registered representatives are regulated by FINRA under a suitability standard. Under suitability, a recommendation is acceptable if it is suitable for the client given their financial situation, objectives, and risk tolerance.

"Suitable" is a wide lane. A commission-heavy annuity product might be "suitable" for a 55-year-old investor approaching retirement even if a lower-cost index fund would produce better outcomes. The question isn't "is this the best option for this client?", it's "can this recommendation be defended as appropriate?"

Regulation Best Interest

In 2020, the SEC adopted Regulation Best Interest (Reg BI), which raised the standard for broker-dealers above basic suitability. Under Reg BI, brokers must act in the "best interest" of retail customers and disclose conflicts of interest.

This sounds similar to the fiduciary standard, but there are meaningful differences in how conflicts of interest are handled. Under the fiduciary standard, an advisor must manage or eliminate conflicts. Under Reg BI, a broker must disclose conflicts but can continue the conflicted practice after disclosure.

Form CRS (the relationship summary document) was introduced alongside Reg BI and is supposed to disclose the standard that applies to a given firm. If you've received a Form CRS, the section "what are your legal obligations to me" tells you which standard applies.

Fee-only as a proxy for fiduciary

The cleanest way to identify a fiduciary advisor: look for fee-only advisors. A fee-only advisor receives compensation exclusively from client fees, no commissions from product sales, no revenue sharing from fund companies, no trailing payments from insurance products.

Fee-only is not the same as fee-based. A fee-based advisor charges fees and may also earn commissions. Both "fee-only" and "fee-based" sound similar; only fee-only eliminates commission-based conflicts.

NAPFA (the National Association of Personal Financial Advisors) maintains a directory of fee-only fiduciary advisors. The Garrett Planning Network lists hourly fiduciary planners.

Why it matters in practice

Consider an advisor who is deciding whether to recommend a mutual fund with a 0.05% expense ratio and no commission versus a different fund with a 1.2% expense ratio and a 3% sales load (commission paid to the advisor at purchase).

A fiduciary advisor recommends the low-cost fund. The suitability standard allows the advisor to recommend the high-cost fund if it's suitable for the client, and collect the commission.

Over a 30-year investment horizon, the difference between these two funds compounded on a $200,000 portfolio is substantial. Which standard your advisor operates under has real, long-term consequences for your outcomes.

The question to ask

"Are you a fiduciary, at all times, for all advice you provide me?"

A yes or no answer, not a hedged response about fiduciary capacity in certain contexts. Then ask to see the Form CRS or ADV Part 2 that confirms it in writing.
