Market Monitoring Data and Indices

The Market Surveillance Committee (MSC) is mandated to develop and adopt a list of market monitoring indices to analyze the monitoring data or other information collected in connection with market surveillance.

 

In accordance with this mandate, the MSC developed the Catalogue of Market Monitoring Data and Indices (CMMDI), which was promulgated in May 2006. The CMMDI is used as an assessment tool to assess competition and facilitate the determination when a market design, or market rule or sector structure impedes competition, or produces or promotes inefficient or anti-competitive behavior or outcomes, or leads to distortions.

 

With the implementation of Retail Competition and Open Access in the WESM in June 2013, the MSC also developed the Catalogue of Retail Market Monitoring Data and Indices (CRMMDI). The catalogue provides a guide in the monitoring and assessment of the performance of the Retail Market and the activities conducted by the Retail Market Participants, with the end view of ensuring the effective functioning or overall efficiency of the integrated WESM and Retail Market. Said catalogue contains a list of monitoring indices which provide indication of market trends, performance, and circumstances which may require further assessment and enhancements in the Retail Rules. The CRMMDI is complementary with the CMMDI.
