- Policy is only as good as the information at the disposal of policymakers. Few moments illustrate this better than the uncertainty before and after the default of Lehman Brothers and the subsequent decision to stand behind AIG. Authorities were forced to make critical policy decisions, despite being uncertain about counterparties’ exposures and the protection sold against their default. Opacity has been a defining characteristic of over-the-counter derivatives markets – to the extent that they have been labelled “dark markets” (Duffie, 2012). Motivated by the concern that opacity exercerbates crises, the G20 leaders made a decisive push in 2009 for greater transparency in derivatives markets. In Europe, this initiative was formalised in 2012 in the European Markets Infrastructure Regulation (EMIR), which requires EU entities engaging in derivatives transactions to report them to trade repositories authorised by the European Securities Markets Authority (ESMA). Derivatives markets are thus in the process of becoming one of the most transparent markets for regulators. This paper represents a first analysis of the EU-wide data collected under EMIR. We start by describing the structure of the dataset, drawing comparisons with existing survey-based evidence on derivatives markets. The rest of the paper is divided into three sections, focusing on the three largest derivatives markets (interest rates, foreign exchange and credit).

- In this paper, we show both theoretically and empirically that the size of over-the-counter (OTC) markets can be reduced without affecting individual net positions. First, we find that the networked nature of these markets generates an excess of notional obligations between the aggregate gross amount and the minimum amount required to satisfy each individual net position. Second, we show conditions under which such excess can be removed. We refer to this netting operation as compression and identify feasibility and efficiency criteria, highlighting intermediation as the key element for excess levels. We show that a tradeoff exists between the amount of notional that can be eliminated from the system and the conservation of original trading relationships. Third, we apply our framework to a unique and comprehensive transaction-level dataset on OTC derivatives including all firms based in the European Union. On average, we find that around 75% of market gross notional relates to excess. While around 50% can in general be removed via bilateral compression, more sophisticated multilateral compression approaches are substantially more efficient. In particular, we find that even the most conservative multilateral approach which satisfies relationship constraints can eliminate up to 98% of excess in the markets.
