# SEBI enforcement against JPMorgan unit and Mansi Share > Live situation record from CLSTR: https://clstr.news/situations/sebi-enforcement-against-jpmorgan-unit-and-mansi-share > Updated: 2026-08-25T13:29:08.000Z. Sources: 6. Developments: 2. The Securities and Exchange Board of India (SEBI) has issued interim orders banning Copthall Mauritius Investment Ltd., a unit associated with JPMorgan Chase & Co., and Mansi Share and Stock Broking Ltd. from participating in Indian securities markets. The regulator alleges the entities engaged in market manipulation during the Closing Auction Session (CAS) on August 13, 2026. SEBI claims the firms used order spoofing tactics—placing large buy and sell orders and subsequently canceling them—to distort the indicative equilibrium price of the BSE Sensex Index to benefit derivatives positions. In some instances, these orders reportedly accounted for over 90% of all orders. SEBI has impounded approximately Rs 3.68 crore in alleged wrongful gains, with Copthall accounting for roughly Rs 29.6 million and Mansi Share for about Rs 7.2 million. The enforcement action follows the recent implementation of the CAS mechanism, which replaced the Volume-Weighted Average Price method on August 3, 2026. ## Timeline ### 2026-08-25: SEBI bans JPMorgan entity and Mansi Share for market manipulation SEBI has banned a JPMorgan Chase entity and Mansi Share from Indian markets following alleged manipulative trading during a new closing auction session in August 2026. 2 sources. https://clstr.news/cluster/sebi-bans-jpmorgan-entity-and-mansi-share-for-market-manipulation ### 2026-08-19: SEBI bars JPMorgan unit and domestic broker for market manipulation SEBI has barred a JPMorgan-linked unit and a domestic brokerage from Indian markets for allegedly manipulating the new Closing Auction Session to benefit Sensex derivative positions. 5 sources. https://clstr.news/cluster/sebi-bars-jpmorgan-unit-and-domestic-broker-for-market-manipulation --- Cite as: SEBI enforcement against JPMorgan unit and Mansi Share.
