By closely monitoring and investigating suspicious activities, the FCA can hold wrongdoers accountable and deter others from engaging in illicit behavior. This proactive approach is essential in maintaining the integrity and trustworthiness of the financial markets, ultimately protecting the interests of investors and ensuring a level playing field for all market participants.

Furthermore, the publication of this data serves as a transparency measure, allowing the public to gain insights into the prevalence of financial misconduct and the efforts being made to address it. By shedding light on the number of reports related to insider dealing and market manipulation, the FCA demonstrates its commitment to upholding regulatory standards and protecting the integrity of the financial system.

In conclusion, the FCA’s report on suspicious transaction reports in 2025 highlights the ongoing challenges posed by insider dealing and market manipulation in the financial sector. By actively monitoring and investigating these illicit activities, regulators can work towards maintaining a fair and transparent market environment.
