Recent FCA data shows that, on average, two-thirds of MiFID firms cancel their transaction reports every year - with each firm cancelling around 502,000 transactions annually.

Cancellations typically occur when reports contain errors or are mistakenly submitted for unreportable transactions. These issues, often driven by poor data quality and weak accuracy controls, amplify the burden of back reporting and expose firms to operational disruption and regulatory risk.

The result? A costly, resource-heavy process that diverts valuable time and resources while inviting greater scrutiny across the business.
