India’s National Stock Exchange (NSE) has closed its investigation into Jane Street, a global market-making firm, after concluding it found no impact on cryptocurrency markets. The probe, focused on the company’s index derivatives trading through Nuvama Wealth Management Ltd., involved scrutiny of rapid trade reversals. According to NSE, Jane Street provided satisfactory responses and avoided financial penalties following the investigation. While this closure highlights regulatory vigilance in rapidly changing financial landscapes, it also offers insights into global market making strategies. The investigation centered around potential anomalies in pricing associated with rapid trade reversal patterns, but ultimately did not lead to further action.
