How is market abuse enforced differently across regulators?

The SEC and DOJ pursue market abuse criminally and civilly, with penalties including imprisonment. The FCA uses both civil penalties and criminal prosecution for insider dealing and market manipulation. The AMF and BaFin enforce under the EU Market Abuse Regulation (MAR). SEBI and SFC use administrative penalties and market bans. The SESC investigates in Japan but the FSA adjudicates, creating a distinctive split-function model.

How does the SEC enforce securities law in the United States?

The SEC enforces US securities law through civil and administrative proceedings, with penalties regularly exceeding $100 million for major cases. It pursues insider trading, fraud, market manipulation, and registration violations across 1,700+ tracked enforcement actions. The SEC can also refer criminal matters to the Department of Justice for prosecution.

Market Abuse Enforcement: How the FCA, SEC, AMF, SEBI and SFC Compare

Market Abuse Enforcement: Global Comparison

Market abuse enforcement is one of the most internationally coordinated areas of financial regulation, yet enforcement approaches vary dramatically across jurisdictions. The FCA, SEC, AMF, SEBI, and SFC each bring distinct powers, penalty frameworks, and prosecution strategies to insider trading and market manipulation cases.

How Regulators Compare

Criminal vs Civil Enforcement

The SEC primarily pursues civil enforcement, referring criminal cases to the DOJ. The FCA has its own criminal prosecution powers for insider dealing and market manipulation. The AMF operates through a Sanctions Commission with judicial independence. SEBI uses administrative penalties, while the SESC investigates and recommends FSA action.

Penalty Frameworks

SEC penalties can include disgorgement of profits plus civil penalties up to three times the profit gained. FCA penalties use a five-step framework based on revenue from the relevant activity. AMF penalties reach €100 million or ten times profit. SEBI penalties are calculated on a per-breach basis.

Detection Capabilities

All major regulators invest heavily in surveillance technology. The SEC's Market Abuse Unit uses data analytics to detect suspicious trading patterns. The FCA operates market surveillance through its Intelligence and Oversight division. ESMA coordinates cross-border market abuse detection across EU markets.

Enforcement Trends

Market abuse enforcement is evolving through enhanced data analytics, cross-border cooperation via IOSCO, increased personal accountability for traders and compliance officers, and growing attention to new market manipulation techniques including social media-driven schemes.

Practical Implications

Firms operating across jurisdictions face compound market abuse risk — the same conduct can trigger enforcement in multiple jurisdictions simultaneously. Cross-border information sharing means regulators can pursue parallel investigations with shared evidence.
