In 2010 the Financial Stability Board delivered a Report “Implementing OTC Derivatives Market Reforms” where it sets 21 recommendations to improve the functioning, transparency and regulatory oversight of over-the-counter (OTC) derivatives markets. Concerning transparency the report recommends that the authorities must have full and timely access to the data on all OTC derivatives transactions, which must be reported to trade repositories (TRs). The comprehensive record of derivative transactions in Banco de México, in particular OTC transactions, was a key element to determine that the Central Bank would perform the information role of a trade repository. For that purpose it was necessary to update data requirements to accommodate new developments in the markets and instruments, include information recommended for TRs and to improve the management of data. In particular it was necessary to improve information on collaterals, netting agreements, platforms, standardization, and central counterparties.
