The European Securities and Markets Authority (ESMA), the EU’s securities markets regulator, is today publishing a study showing how regulatory reporting data can be used to identify risks in derivatives markets, such as occurred in the case of Archegos.

In the study, ESMA finds that the build-up of exposures by Archegos, a US family office whose collapse in March 2021 resulted in more than USD 10bn in losses, can be seen in data reported under the European Market Infrastructure Regulation (EMIR). The high level of concentration and the associated risks posed by the firm are also visible.

These findings show how regulatory data collected under EMIR can be used to monitor leverage and concentration risk arising in derivatives markets, and could foster the development of early warning indicators by supervisory authorities to track different types of risk.

This article is an ex-post analysis of a relevant financial market event and aims to foster further financial stability analysis, as well as to feed into ongoing work on using EMIR, and other regulatory datasets, to identify and monitor risks, including at the international level by the European Systemic Risk Board and Financial Stability Board.


In March 2021, the default of Archegos, a US family office, led to large losses for some global banks. Archegos was able to accumulate large leveraged exposures on equities by entering into derivatives transactions with banks. When the price of the underlying stocks started to decline, the firm was unable to meet variation margins, resulting in the liquidation of the stocks by the banks.
