The Depository Trust & Clearing Corporation has begun to collect trading data across all the major US over-the-counter derivatives markets for the first time, marking a key milestone in the G20's efforts to reform financial markets after the 2008 financial crisis.

The US post-trade provider said in a statement last night that major US swaps dealers were submitting data for their credit, interest rate, equity, foreign exchange and commodity derivatives trades into its US trade repository.
