UBS Securities LLC has settled enforcement action with Nasdaq over failures in its market access controls that left warrant orders vulnerable to erroneous execution. The settlement, filed under Case No. 2025.03.0456, addresses control deficiencies identified between August 29, 2023 and July 16, 2025, during which the firm’s risk management systems lacked adequate safeguards for warrant trading despite maintaining controls for other securities.
- Review Period: August 29, 2023 to July 16, 2025
- Prior Fine: $90,000 by Nasdaq (May 3, 2022)
- Violation Type: Failure to prevent erroneous warrant orders
- Affected Securities: Warrants not covered by Limit Up/Limit Down (LULD) protections
- UBS Operations: 1,900 registered persons across 25 branch offices
The core issue centered on UBS Securities‘ Order Routing Hub system, which employed anti-redundancy logic that prevented orders from triggering downstream controls once they had been reviewed by firm personnel at the parent-order level. While securities subject to SEC-approved LULD bands received additional automated protection, warrants fell outside this framework. This gap meant that after warrant orders were released following personnel review, they were not subject to additional automated safeguards, creating a control deficiency for an entire asset class.
The settlement requires UBS to accept findings that violated multiple regulations, including Section 15(c)(3) of the Securities Exchange Act of 1934 and SEC Rules 15c3-5(b) and 15c3-5(c)(1)(ii), which mandate broker-dealers establish risk management controls reasonably designed to prevent erroneous orders and manage financial risks associated with market access. The firm neither admitted nor denied the violations as part of the settlement agreement, which includes a provision preventing Nasdaq from bringing future actions based on the same factual findings.
This enforcement action represents the second disciplinary matter for UBS Securities involving market access controls in recent years. The firm, headquartered in New York and a subsidiary of Swiss banking giant UBS AG, has operated as a Nasdaq member since July 2006, providing investment banking, research, and sales and trading services to corporate and institutional clients.
