• Is This Normal? The Cost of Assuming that Derivatives Have Normal Returns

  Staff Working Paper 2024-46 Radoslav Raykov

  Derivatives exchanges often determine collateral requirements, which are fundamental to market safety, with dated risk models assuming normal returns. However, derivatives returns are heavy-tailed, which leads to the systematic under-collection of collateral (margin). This paper uses extreme value theory (EVT) to evaluate the cost of this margin inadequacy to market participants in the event of default.
