(2)Given the agreement reached by the parties to the G20 in Pittsburgh on 25 September 2009 to move trading in standardised OTC derivative contracts to exchanges or electronic trading platforms, it is appropriate to provide for a suitable range of eligible venues on which trading contemplated by that commitment can take place. Regulation (EU) No 600/2014 underlines, moreover, the need to establish a single set of rules for all institutions in respect of certain requirements and to avoid potential regulatory arbitrage. Therefore, when designating the standardised OTC derivative contracts that will be subject to a trading obligation, it is appropriate that the Union also encourages the development of a sufficient number of eligible venues to allow the trading obligation to be complied with, including in the Union.
