FCA warning: These Firms are on the list

In 2025, the UK‘s Financial Conduct Authority (FCA) intensified its crackdown on financial misconduct, issuing a series of fines and public warnings against both major institutions and forex brokers. This article provides an updated list of brokers, banks, and financial platforms that have been recently fined, banned, or listed on the FCA’s warning list, highlighting the importance of transparency and investor protection in the UKs financial market.

1. Sigma Broking Limited

• On 1 August 2025, the FCA fined Sigma £1,087,300 for severe and sustained failures in transaction reporting (MiFIR) covering the period 1 December 2018 to 1 December 2023.
• The firm reported ~924,584 inaccurate reports — essentially, nearly all its transactions over that period.
• Note: Sigma is a brokerage/metal-broker active in the UK and was previously subject to enforcement in 2022.

2. Barclays Bank plc (and Barclays Bank UK plc)

• The FCA announced on 16 July 2025 that Barclays (via two entities) was fined a total of £42 million (approx) for failings in its financial-crime risk management: one case relating to WealthTek, another relating to Stunt & Co.
• Barclays Bank UK plc fined ~£3.0936 m (reduced)
• Barclays Bank plc fined ~£39.3147 m (reduced)
• The issues involved: opening client money accounts without adequate checks, poor money-laundering controls, and insufficient due diligence checks.

3. Crispin Odey / Odey Asset Management

• In March 2025, the FCA fined and banned Crispin Odey (founder of Odey AM) ~£1.8 million for a lack of integrity and banned him from the financial services industry.
• The regulator took account of non-financial misconduct (sexual misconduct allegations, internal governance failures) as relevant to “fitness and propriety”.

4. Jes Staley

In July 2025 the FCA finalised a ban on the former CEO of Barclays (Staley) from holding senior roles in the financial services industry due to misleading the regulator about his relationship with Jeffrey Epstein. The fine was ~£1.1 million.

5. Clone / Unauthorised Brokers Warning List

The FCA routinely publishes warnings about unauthorised firms (including broker clones) that are not authorised to carry out or promote financial services in the UK.

Conclusion

The FCA‘s enforcement actions in 2025 underscore its firm stance on market integrity and consumer protection. Investors are urged to verify every platform’s regulatory status on the FCA Register and to avoid clone or unauthorized brokers listed on the FCA warning list.
