FCA fines Citigroup’s international broker-dealer £12.6m

The regulator says Citigroup Global Markets failed to properly implement the Market Abuse Regulation (MAR) trade surveillance requirements relating to the detection of market abuse.

By failing to properly implement requirements, Citigroup Global Markets could not effectively monitor its trading activities for certain types of insider dealing and market manipulation.

MAR was introduced in 2016 and expanded requirements to detect and report potential market abuse. It introduced a requirement to monitor both orders and trades to detect potential and attempted market abuse across a broad range of markets and financial instruments.

However, the FCA found that Citigroup Global Markets failed to properly implement the new requirement when it took effect, and took 18 months to identify and assess the specific market abuse risks its business may have been exposed to and which it needed to detect. Citigroup Global Markets’ flawed implementation resulted in significant gaps in its arrangements, systems, and procedures for additional trade surveillance.

Citigroup Global Markets agreed to resolve this case and qualified for a 30% discount. Without this discount, the fine would have been £17,934,030.

Mark Steward, executive director of enforcement and market oversight at the FCA, commented: "The framework for market integrity depends on the partnership between the FCA and market participants using data to detect suspicious trading. By not fully implementing the new provisions when required, Citigroup Global Markets did not carry its full weight in this partnership, impacting market integrity and the overall detection of market abuse."
