SEBI Cuts Commodity Derivatives Stress Test Threshold to 5
SEBI is like a referee for India's financial markets, making sure they run safely.
Companies that trade commodities, like gold, oil, or wheat, have to follow special rules.
One rule is called a stress test, which is like a pretend game of 'what if prices jump wildly?'
The Z-score is a measuring stick that shows how far a price move is from what usually happens.
Before, the stress test included very extreme price jumps equal to a score of 10.
Now the referee has lowered that to 5, meaning the test uses smaller extreme jumps.
This does not mean prices can only move 5 percent — prices can still jump more in real life.
It just means the test no longer counts the most enormous historical shocks.
Because the test is less scary, companies may not need to keep as much safety money set aside.
The money they save can be used for other things while still keeping the market well protected, since a score of 5 still covers more than 99.9999 percent of normal market conditions.
SEBI has reduced the Z-score threshold for commodity derivatives stress tests from 10 to 5, effective immediately.
The change aims to ease compliance requirements and improve capital efficiency for market participants.
The Z-score is calculated using the mean and standard deviation of returns over the Margin Period of Risk (MPOR), based on 15 years of historical data.
The revised threshold caps historical price shocks at five standard deviations, potentially lowering the capital Clearing Corporations must maintain.
A Z-score of 5 covers more than 99.9999% of normal market conditions, with the impact varying across commodities based on their historical price shocks.
