Taking a longer-term perspective for the years 1970–2011 shows that financial crises were followed by output losses relative to GDP of 26 % for emerging economies and 33 % for advanced economies (Laeven and Valencia 2012).
After giving multiple extensions to banks in this regard, it was recently decided that the potential risk on T+1 would be reckoned at 50% of the settlement amount. Also this amount would be reckoned as CME at the end of T+1 if margin payment / early pay in does not come in. IPC would also be reckoned for the purpose of capital adequacy.
