(14)Before regulatory technical standards adopted pursuant to Article 5(2) of Regulation (EU) No 648/2012 enter into force, counterparties cannot foresee whether the OTC derivative contracts they conclude would be subject to the clearing obligation on the date that obligation takes effect. This uncertainty has a significant impact on the capacity of market participants to accurately price the OTC derivative contracts they enter into since centrally cleared contracts are subject to a different collateral regime than non-centrally cleared contracts. Imposing forward-clearing to OTC derivative contracts concluded before the entry into force of this Regulation, irrespective of their remaining maturity on the date on which the clearing obligation takes effect, could limit counterparties' ability to hedge their market risks adequately and either impact the functioning of the market and financial stability, or prevent them from exercising their usual activities by hedging them by other appropriate means.
