Is Stifel Nicolaus a Fiduciary? What Its Own Form CRS Says (2026)

Guides › Financial Advisor Fees

Updated September 22, 2026. Quick answer: It depends which hat Stifel Nicolaus is wearing. As your investment adviser, Stifel Nicolaus owes you a fiduciary duty under the Investment Advisers Act of 1940. As your broker-dealer, Stifel Nicolaus owes you Regulation Best Interest, a real and enforceable standard, but not a fiduciary duty. Stifel Nicolaus’ own Form CRS states: “When we provide you with a recommendation as your broker-dealer or act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours.”

How it’s registered

From Stifel, Nicolaus & Company, Incorporated Form CRS (Effective April 21, 2025): “Stifel, Nicolaus & Company, Incorporated is registered with the Securities and Exchange Commission (“SEC”) as a broker-dealer and an investment adviser.”

The standard of conduct, in its own words

“When we provide you with a recommendation as your broker-dealer or act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours.”

On commissions: “In brokerage, you will pay Stifel a “commission” or other “transaction-based” fee for each transaction that is executed.”
