GameStop frenzy triggered $2 billion margin breach at OCC  

Total initial margin held by the OCC's default fund stood at $114.4 billion in Q1

The Options Clearing Corporation (OCC) incurred a $2.01 billion initial margin (IM) breach in the first quarter, driven by a borrowing position in GameStop shares between January 25 and January 27.  

The peak IM breach in Q1 dwarfed the previous record for the central counterparty (CCP) of $652 million in Q3 2016, according to the latest publicly available figures.
