FIA comments on ION Group cyber incident

1 February 2023

FIA is aware of network issues caused by a cyber incident on certain ION Group systems which are impacting the trading and clearing of exchange traded derivatives by ION customers across global markets. We are working with impacted members, including clearing firms and exchanges, as well as market regulators and others, to assess the extent of the impact on trading, processing, and clearing.

FIA is coordinating communication and information sharing, through regular calls with relevant parties assessing the firms impacted, how firms can work together to mitigate the disruption and seeking clarity over concerns about affected regulatory obligations and reporting.

For firms in the derivatives industry looking for assistance, please email:

  • Don Byron, FIA's Head of Global Industry Operations & Execution, at
