The Securities and Exchange Board of India has proposed tighter circuit limits and longer trading suspensions to contain extreme price movements in shares on which futures and options trade. The proposals come in the wake of the massive decline in the stock prices of Adani group companies after the release of activist short-seller Hindenburg Research’s report accusing the conglomerate of various irregularities, including stock price manipulation.

In a consultation paper released on Saturday, India’s market regulator has proposed suspending trading for an hour, as opposed to the current 15 minutes, if a share in the futures and options segment falls or rises by 10% in a day, and then allowing it to move only a further 2%, against the current 5%.

“Cooling off period allows information to flow to a wider set of investors and provides them a window to assess the developments when the price of the scrip/contract is subject to temporary floor/ceiling. If after the cooling-off period, price keeps moving in one direction, requiring multiple rounds of flexing, it may be more appropriate to provide a higher cooling off period of more than 15 minutes for market participants to assess the situation before subsequent rounds of flexing of price band,” SEBI said, explaining its rationale.

SEBI’s consultation paper, released on Saturday, follows the clean chit given by a Supreme Court-appointed expert committee set up to probe regulatory failures with regards to related-party transactions and alleged manipulation of Adani group stocks. The panel looked into four broad areas: market volatility due to the price movement of Adani group stocks following the Hindenburg allegations, compliance with minimum public shareholding requirements, disclosure of transactions with related parties and stock price manipulation.

In its report—submitted to the SC earlier this month but made public last week—the committee has avoided giving any tangible conclusions, instead saying it won’t be able to establish at this stage if SEBI failed in dealing with the alleged contravention of security market laws.

Meanwhile, Adani stocks lost a combined $10 billion in market value last week, weighed down by MSCI’s move to exclude Adani Total Gas and Adani Transmission from its India gauge and concerns over potential dilution of the conglomerate’s fundraising plans. The 24 January release of the Hindenburg report had spurred a rout that at one point wiped out more than $150 billion from the group’s market cap.
