Following a meeting of the G20 Leaders in September 2009 in which a number of commitments regarding the operation of over-the-counter derivatives (OTCD) markets were made, including the statement that all OTCD contracts should be reported to trade repositories (TRs) in order to improve transparency, mitigate systemic risk and protect against market abuse in the OTC derivatives markets, the Financial Stability Board advocated that IOSCO and BIS take forward this project on authorities' access to trade data.

This report has been produced to provide guidance to TRs and authorities on access to TR-held OTCD transaction data, as well as possible approaches to addressing confidentiality concerns and access constraints.
