Jane Street faced a ban, highlighting regulatory risks and adding obstacles to the path of listing on India's top stock exchange.

The temporary trading ban imposed on Jane Street Group LLC by the Indian securities regulator has sparked concerns among investors. They fear that trading volume in the country's busy derivatives market may decline, which could harm the business of India's top exchange. The stock price of the National Stock Exchange of India has already dropped nearly 10% in the unlisted market from its recent highs. This exchange dominates over 90% of the stock derivatives market. According to Umesh Chandra Paliwal, co-founder of the trading platform UnlistedZone, the trading price for these stocks is around 2100 to 2150 Indian Rupees per share. Before the decline in the stock of the National Stock Exchange of India, there was a remarkable surge since October, mainly driven by external hopes for the listing of the world's largest stock derivatives exchange. After the exchange sought a settlement in a long-standing legal dispute with the Indian securities regulator, the stock briefly climbed to 2400 Indian Rupees as this move was seen as clearing a key obstacle for its IPO. At this price, the exchange's valuation is estimated at around 69 billion US dollars, ahead of global peers like Deutsche Brse and Nasdaq. Paliwal stated: "The issues with Jane Street have raised concerns about the potential impact on derivative trading volume, which will directly affect the National Stock Exchange of India."
