Investigating initial margin procyclicality and corrective tools using EMIR data

Abstract: Initial margin (IM) reduces counterparty credit risk in derivative markets. Notwithstanding efforts to limit potential procyclical effects of IM-setting practices, there is an ongoing debate about whether the current framework sufficiently addresses this concern, in particular when Value-at-Risk (VaR) models are used for setting IM. This article provides further insights into this issue. First, using EMIR data, we provide an overview of outstanding IM in the euro area derivative market and identify the most relevant sectors for the exchange of IM. Second, using a VaR IM model in line with industry practice, we show that aggregate IM can potentially vary substantially over a long-term horizon. Finally, we show that an IM floor based on a standardised IM model could be an effective tool for reducing IM procyclicality. JEL Classification: G10, G23, G28
