The Bank for International Settlements (BIS) on Wednesday launched the 11th edition of its triennial central bank survey on the global foreign exchange (FX) and over-the-counter (OTC derivatives markets.

The survey “aims to increase the transparency of OTC markets and to help central banks, other authorities and market participants monitor developments in global financial markets,” the BIS says in its announcement.

Data on daily turnover in OTC markets for FX and interest-rate derivatives will be collected in April, and data on the value of OTC derivatives will be collected at the end of June.

The preliminary results of the survey will be published in early September, and the results will be published in December.

More than 1,200 financial institutions located in 52 countries, including Canada, will contribute to the survey, which is co-ordinated by the BIS.

Participating central banks survey the financial institutions in their jurisdiction and submit national aggregates to the BIS, which calculates and publishes global totals.
