Open source pageSummary
Check the official recordThe Securities and Exchange Board of India modifies the Z-score requirement for standardized stress testing in the commodity derivatives segment. Clearing corporations must now use a Z-score of 5 to replace extreme price movements that exceed this threshold during peak historical return calculations. This change replaces the previous Z-score requirement of 10. The modification applies to the calculation of mean and sigma of returns over the applicable margin period of risk across a 15-year period. This update aims to facilitate ease of doing business in the commodity derivatives market. The new requirement takes effect immediately.
