SEBI’s temporary trading ban on global trading firm Jane Street is rippling through India’s capital markets, not just by denting expiry day turnover at the NSE, but also by pulling down the exchange’s private market valuation. According to UnlistedZone, NSE shares are now trading between 2,100 rupees and 2,150 rupees apiece, nearly 10% below recent highs. The curbs on the global trading firm have raised concerns that derivatives trading volumes may take a hit, which directly affects NSE’s core business, according to Umesh Chandra Paliwal, co-founder of the trading platform.
