According to FINRA, Credit Suisse Securities (USA) LLC was censured and fined a total of $7,125,000 (of which $445,312.50 is payable to FINRA) for failing to establish and maintain a supervisory system and procedures reasonably designed to detect and prevent market manipulation and insider trading.

The firm's surveillance failures were extensive and systemic. Credit Suisse's surveillance systems failed to analyze hundreds of millions of trade and order records, leaving enormous gaps in the firm's ability to detect potentially violative trading by its customers. As a result of missing or potentially inaccurate data in its surveillance systems, the firm did not detect and investigate numerous instances of potentially violative trading.

FINRA's analysis revealed that the firm's surveillance reports failed to detect multiple specific instances of potentially manipulative trading by firm customers, including potential spoofing, marking the open, wash trades, and insider trading. Spoofing involves placing orders with the intent to cancel them before execution to create a false impression of market interest. Marking the open refers to executing trades at or near the market open to manipulate opening prices. Wash trades are simultaneous or near-simultaneous buying and selling that creates misleading market activity without actual change in beneficial ownership.

Despite the critical importance of accurate data for surveillance, Credit Suisse had no system or procedure to monitor the accuracy and completeness of data supplied to its surveillance systems. Four separate firm audits found that the database was omitting data and transmitting flawed data, and that the firm lacked controls to compensate for the database's unreliability. The firm retained an outside consultant who recommended replacing the database entirely due to the risks it posed to the firm's regulatory and compliance program.

Despite these warnings, Credit Suisse did not initially make material progress to replace the problematic database and did not substantially complete the replacement until September 2020. This delay meant the firm operated with inadequate surveillance capabilities for an extended period, during which customer misconduct could go undetected.

For investors, this case illustrates the importance of broker-dealer surveillance systems in maintaining market integrity. These systems help detect manipulation and insider trading that can harm market fairness and investor confidence. The substantial fine reflects the severity of these failures.
