An Enhanced Initial Margin Methodology to Manage Tail Credit Risk

Speaker: Lucia Cipolina Kun, Morgan Stanley

Location: Warren Weaver Hall 1302

Date: Tuesday, September 24, 2019, 5:30 p.m.


Recently Regulators issued the Uncleared Margin Rules requiring the posting of initial and variation margin for deals traded bilaterally between financial institutions. The use of a standardized initial margin is now widespread in the industry but its simplified approach comes with its limitations. We propose a method to improve the initial margin calculation to capture the credit tail risk arising particularly from lower rated counterparties.

The proposed methodology is fully compliant with the risk-neutral pricing framework, and enables improved risk management for dealers and, subsequently, a route for troubled institutions to access the derivative markets.
