EMIR is a European regulation that aims to mitigate risks in over-the-counter (OTC) derivatives markets in response to the 2008 financial crisis. It establishes requirements around clearing, risk mitigation, reporting and oversight of derivatives. Key provisions include mandatory clearing of eligible OTC derivatives, risk controls for non-cleared OTC derivatives, reporting all derivatives trades to repositories, and common regulation of clearing houses and repositories. The regulation's requirements have begun phasing in since 2013 and will continue being rolled out through 2015. It applies to derivatives transactions executed by financial and large non-financial counterparties established in the EU.
