The 20 Largest FCA Fines in History
The largest FCA fine ever issued was £284,432,000 against Barclays Bank in November 2015 for foreign exchange trading failures. Since 2013, the FCA has imposed over £4.9 billion across hundreds of enforcement actions, with AML and market abuse representing the largest categories by fine value. This analysis examines the 20 biggest FCA fines of all time, exploring the circumstances behind each penalty and drawing out practical lessons for compliance professionals and risk managers.
Top 20 FCA Fines - Complete List
1. Barclays Bank Plc - £284,432,000 (November 2015)
This remains the largest FCA fine ever issued. Barclays was penalised for failing to control business practices in its foreign exchange (FX) operations, where traders participated in improper G10 spot FX trading. The FCA found that the bank failed to manage conflicts of interest effectively, while systems and controls over FX trading proved wholly inadequate. Traders improperly shared confidential client information through electronic chat rooms and attempted to manipulate FX benchmark rates, causing significant harm to market integrity.
2. UBS AG - £233,814,000 (November 2014)
UBS received the second-largest FCA fine for significant failings in its FX business. The regulator identified a systematic failure to properly manage conflicts of interest in treasury operations, with traders engaging in collusive behaviour that undermined fair market practices.
3. Deutsche Bank AG - £227,000,000 (January 2017)
Deutsche Bank was fined for serious anti-money laundering control failures related to a $10 billion Russian money laundering scheme conducted through so-called 'mirror trades'. The FCA found inadequate transaction monitoring that failed to detect suspicious patterns, weak correspondent banking controls, and poor oversight of high-risk business lines. This case demonstrated how AML failures can facilitate large-scale financial crime when controls are insufficient.
4. Citibank N.A. - £225,575,000 (November 2014)
As part of the wider FX manipulation scandal, Citibank was fined for failures in its G10 spot FX trading business. The bank's traders participated in collusive practices that the FCA determined caused serious harm to financial markets.
5. JP Morgan Chase Bank N.A. - £222,166,000 (November 2014)
JP Morgan received this substantial fine as part of the coordinated FX manipulation enforcement action, reflecting the scale of misconduct across major financial institutions in the foreign exchange markets.
6. HSBC Bank Plc - £176,000,000 (December 2021)
HSBC was fined for significant failings in its anti-money laundering transaction monitoring systems. The deficiencies affected millions of customers over an eight-year period, highlighting how technology failures in AML systems can lead to substantial regulatory penalties.
7. Royal Bank of Scotland Plc - £217,000,000 (November 2014)
RBS was fined for FX trading failures and inadequate controls over its foreign exchange business, forming part of the industry-wide enforcement action against FX manipulation.
8. Credit Suisse - £147,190,200 (2023)
Credit Suisse received multiple fines for various compliance failures including significant AML deficiencies, reflecting ongoing concerns about the bank's control environment.
9. Lloyds Banking Group - £117,000,000 (2015)
Lloyds was penalised for failures in handling PPI complaints fairly and treating customers appropriately, demonstrating the FCA's focus on consumer protection.
10. Standard Chartered Bank - £102,163,200 (April 2019)
Standard Chartered was fined for AML control failures in its correspondent banking business, where inadequate oversight of high-risk relationships enabled potential financial crime.

Key Lessons from the Biggest FCA Fines
Anti-Money Laundering Remains the Primary Risk
AML failures account for six of the top 20 FCA fines, representing the single largest category of serious breaches. For a deep dive into anti-money laundering enforcement, see our complete guide to FCA AML fines. Firms must recognise that robust transaction monitoring systems are not optional but essential infrastructure. Adequate KYC and customer due diligence processes need continuous investment and refinement, while suspicious activity reporting must be embedded as a core business function rather than a compliance afterthought. Regular, meaningful AML training for all relevant staff helps build the human element of defence against financial crime.
Market Conduct and Trading Controls
The FX scandal resulted in over £1.1 billion in fines to major banks in a single coordinated action, demonstrating the FCA's willingness to pursue industry-wide misconduct. Proper information barriers between business functions are essential, as is comprehensive surveillance of trading communications. Clear, enforceable policies on handling confidential information must be supported by strong first-line controls within trading operations themselves.
Investment in Systems and Controls
Most large fines cite inadequate systems and controls as a root cause of regulatory breaches. The message for firms is clear: investment in RegTech and compliance technology is not merely a cost centre but a critical business protection. Firms that view compliance infrastructure as discretionary spending often find themselves facing penalties that dwarf any savings from underinvestment.
FCA Fines in Context
Since 2013, the FCA has issued over £4.9 billion in total fines, with the average penalty among the top 20 cases reaching £156 million. Anti-money laundering failures represent the most common breach category leading to significant fines, while the largest single penalty of £284 million against Barclays demonstrates the regulator's willingness to impose substantial sanctions for serious misconduct. These figures underscore the material financial risk that compliance failures pose to regulated firms. For year-by-year analysis, see our FCA enforcement trends overview.
