Table of Contents
Our attorneys have thoroughly reviewed public records, including the FINRA BrokerCheck report for Sabrina Siou as of September 24, 2026. The key findings are presented below:
- CRD Number: 8011952
- Former Position: Registered Representative at JPMorgan Chase Bank, N.A.
- Registration Dates: First registered with FINRA in 2005; with JPMorgan since 2014
- City/State: New York, NY
Red Flag: Employment Separation Disclosure
The primary concern on Sabrina Siou’s regulatory record is an employment separation disclosure. On July 16, 2026, JPMorgan Chase Bank, N.A. filed a report stating that Siou was discharged. According to the disclosure, Siou, serving as an affiliate bank employee, accessed the profile of a customer she knew personally, without authorization or a business purpose.
This is a significant disclosure for investors, as unauthorized access to a customer profile can raise material concerns about professional standards, firm supervision, and adherence to industry best practices.
Regulatory Standards Implicated
Although Sabrina Siou has not been subject to customer dispute claims, lawsuits, or regulatory actions, the circumstances surrounding her separation are noteworthy under critical FINRA rules and securities regulations:
- FINRA Rule 3110 (Supervision): Requires firms to maintain a system that reasonably supervises personnel, including enforcement of written supervisory procedures.
- FINRA Rule 2010 (Commercial Honor): Mandates that member firms observe high standards of commercial honor and just and equitable principles of trade, especially when customer data is involved.
- Regulation Best Interest (Reg BI): Enhances the standard of broker conduct, requiring that advisors put their clients’ interests first, disclose all material information, and mitigate conflicts.
Unauthorized access to client profile information may reflect a breakdown in one or more of these regulatory duties, impacting investor trust and potentially the safety of client data.

Why a Separation Disclosure Signals Caution for Investors
Separation for unauthorized account access is a red flag that can affect investor confidence in an advisor’s integrity and judgment. Even in the absence of broader complaints, such issues may point to lapses in judgment or weaknesses in supervisory structures at major institutions like JPMorgan Chase Bank, N.A.
- Unauthorized access to client information can expose investors to privacy risks.
- It may indicate potential violations of a firm’s internal controls or industry regulations.
- Departures of this kind may warrant further review by counsel if you have concerns about account activity or related losses.
When regulators or employers identify misconduct involving client data or trust, investors may wish to seek clarity, particularly if they believe they experienced financial losses or irregular account activity.
The Importance of Regulation Best Interest (Reg BI) and Your Rights
Reg BI requires that advisors and broker-dealers act in a retail customer’s best interest at the time of any recommendation. Firms like JPMorgan Chase Bank, N.A. are expected to maintain robust internal controls and provide transparent disclosures. Even in cases where complaints are not on file, any indication of a potential breach may deserve careful review to help protect your assets and legal rights.
