New Delhi, July 4 (NationPress) Zerodha’s co-founder and CEO Nithin Kamath commended the Securities and Exchange Board of India (SEBI) for its decisive action against the US-based trading firm Jane Street. He highlighted that India’s strong regulatory environment prevents the adoption of market practices prevalent in Western countries.
In a post on the social media platform X, Kamath stated: "None of these practices would be permitted in India, thanks to our regulators," referring to US market structures like dark pools and payment for order flow—mechanisms frequently criticized for benefitting hedge funds at the expense of retail investors.
Kamath’s remarks followed SEBI’s interim order, which accused Jane Street and its associated entities of manipulating the Bank Nifty index through intricate intra-day strategies.
The regulator discovered that the firm garnered substantial profits exceeding Rs 43,289 crore between January 2023 and March 2025, primarily through options trades, by artificially inflating and then lowering the index, particularly on expiry days.
Kamath emphasized the gravity of the alleged manipulation, stating: "Kudos to SEBI for targeting Jane Street. If the claims hold true, it’s a clear case of market manipulation."
He expressed concern regarding the potential repercussions of this action, noting that proprietary trading firms like Jane Street account for nearly 50 percent of India’s options trading volumes.
If these firms decide to withdraw in response to SEBI’s enforcement, the retail investor participation—currently around 35 percent—may also suffer.
"This could spell trouble for both exchanges and brokers," Kamath asserted.
He further mentioned that the forthcoming days would be crucial in assessing the Indian market’s dependency on large proprietary trading firms.
“F&O volumes might illustrate just how reliant we are on these trading giants,” he concluded.
