Fiduciary Duty vs Suitability Standard
A legal obligation to act in the client's best interest. A recommendation must be appropriate given the client's profile.
What is the difference between Fiduciary Duty and Suitability Standard?
Fiduciary = must be the client's best option. Suitability = must merely be appropriate. The gap is where most conflicted advice lives.
| Fiduciary Duty | Suitability Standard | |
|---|---|---|
| In one line | A legal obligation to act in the client's best interest. | A recommendation must be appropriate given the client's profile. |
| Example | Between two comparable funds, a fiduciary cannot choose the one paying them more without disclosure and a best-interest rationale. | A suitable but expensive fund could once be recommended over a cheaper identical one. |

What is Fiduciary Duty?
The highest standard of care in financial advice. It comprises a duty of loyalty (put the client first, disclose and manage conflicts) and a duty of care (competent, diligent advice). Registered investment advisers owe it under the Investment Advisers Act of 1940.
What is Suitability Standard?
The historical broker-dealer standard: recommendations must fit the client's objectives, risk tolerance, and circumstances, but need not be the best available option. Largely superseded for retail recommendations by Regulation Best Interest in 2020, though the concept still frames the analysis.
