The Central Bank of Russia has published a concept for disclosing anonymized market transaction data collected through reports from supervised organizations. It is seeking market participants’ views on which information would be useful and their preferred formats and access channels. The proposed disclosures would address information asymmetries and make current market data equally accessible for use in analytical products. Some exchange transaction data are currently available only in aggregated form or for a fee, while information on over-the-counter transactions is fragmented and lacks transparency. Disclosures would preserve confidentiality, potentially using special tags to identify related transactions. The central bank already publishes data on over-the-counter ruble-denominated interest rate swaps. Following discussions with market participants, it may develop uniform approaches to publication and broaden the information disclosed.
