NSE Clearing has developed a comprehensive risk containment mechanism for the Currency derivatives segment. The most critical component of a risk containment mechanism for NSE Clearing is the online position monitoring and margining system. The actual margining and position monitoring is done on-line, on an intra-day basis. NSE Clearing uses the SPAN' (Standard Portfolio Analysis of Risk) system for the purpose of margining, which is a portfolio based system.
NSE Clearing collects initial margin up-front for all the open positions of a CM based on the margins computed by NSE Clearing-SPAN'. A CM is in turn required to collect the initial margin from the TMs and his respective clients. Similarly, a TM is required to collect upfront margins from his clients.
Initial margin requirements are based on 99% value at risk over a one day time horizon. However, in the case of futures contracts, where it may not be possible to collect mark to market settlement value, before the commencement of trading on the next day, the initial margin is computed over a two-day time horizon, applying the appropriate statistical formula. The methodology for computation of Value at Risk percentage is as per the recommendations of SEBI from time to time.
Initial margin requirement for a member:
- For client positions - is netted at the level of individual client and grossed across all clients, at the Trading/ Clearing Member level, without any setoffs between clients.
- For proprietary positions - is netted at Trading/ Clearing Member level without any setoffs between client and proprietary positions.
For the purpose of SPAN Margin, various parameters are specified from time to time.
IIn case a trading member wishes to take additional trading positions his CM is required to provide Margin deposit to NSE Clearing. MD can be provided by the members in the form of Cash, Bank Guarantee, Fixed Deposit Receipts and approved securities & Government securities.
