“G20 Leaders agreed in 2009 that all over-the-counter (OTC) derivatives contracts should be reported to trade repositories (TRs) as part of their commitment to reform OTC derivatives markets in order to improve transparency, mitigate systemic risk and protect against market abuse. Aggregation of the data reported across TRs is necessary to help ensure that authorities are able to obtain a comprehensive view of the OTC derivatives market and activity. Following the 2014 FSB Feasibility study on approaches to aggregate OTC derivatives data, the FSB asked the CPMI and IOSCO to develop global guidance on the harmonisation of data elements reported to TRs and important for the aggregation of data by authorities, including Unique Transaction Identifier (UTIs) and Unique Product Identifiers (UPIs). This consultative report is one part of the CPMI-IOSCO Harmonisation Group’s response to its mandate. It focuses on the harmonised global UTI, whose purpose is to uniquely identify each OTC derivative transaction required by authorities to be reported to TRs. The final objective is to produce clear guidance as to UTI definition, format and usage that meets the needs of UTI users, is global in scale, and is jurisdiction-agnostic, thus enabling the consistent global aggregation of OTC derivatives transaction data. The report seeks general and specific comments and suggestions from responders by 30 September 2015, to be sent to both the CPMI secretariat and the IOSCO secretariat.”
