Standardization Working Group


This Working Group’s purpose is to focus on the ISSA participants’ standardization journey – understanding the challenges, as well as the opportunities available – so that ISSA is able to offer best practice guidance and to promote standardization. This will have a positive impact on the Securities Services (post-trade) industry through increased efficiency and reduced risk, as well as an improved investor experience.


The Standardization agenda is broad and covers overall industry standardization as well as local market practices.

In scope topics under consideration include:

  • DLT standards and market adoption  
  • ESG Standards
  • ISO 20022
  • API standards 
  • Data standards which are not covered under other topics (e.g. Private Markets, FIX)

For each topic, the Working Group will review what specific areas should be focused on depending on the needs of the Securities Services industry. The plan will be to adopt an agile approach focusing on one area at a time. In addition to this primary focus, the Standardization Working Group will also engage with other ISSA Working Groups to seek and provide input to the broader discussion on standards and to maintain a holistic view over the progress being made on the Standardization agenda.
