The White Law Group Reviews the Regulatory History of Jefferies LLC

The White Law Group is investigating potential securities claims involving Jefferies LLC (CRD: 2347) , a global investment bank and broker-dealer headquartered in New York. Despite its reputation as a leading Wall Street firm, Jefferies has faced multiple regulatory sanctions and broker misconduct cases that raise concerns for investors.

FINRA Sanctions and Settlements

September 10, 2025 – FINRA fined Jefferies $1,000,000 for inaccurate reserve formula calculations that caused significant customer and broker-dealer reserve deficiencies. Regulators also found that the firm failed to maintain adequate supervisory systems to ensure compliance with reserve requirements.

December 27, 2024 – Jefferies reached a $250,000 global settlement with FINRA and multiple exchanges over Regulation M violations. Regulators found that the firm filed inaccurate restricted period notifications and lacked adequate supervisory procedures to prevent improper trading.

Broker Misconduct – Nicholas Stephen Coubrough

Former Jefferies broker Nicholas Coubrough (CRD#: 4678755) was barred from the securities industry by FINRA after refusing to cooperate with a regulatory investigation. Coubrough had previously been discharged from Jefferies in 2024.

Investor Risks
