Jane Street's India trading unit achieved a 494% year-over-year surge in trading gains during the fourth quarter of 2025, marking one of the most significant performance spikes in the firm's regional operations. The results reflect a strategic expansion in local market access, increased order flow from institutional clients, and optimized execution algorithms tailored to Indian equity and derivatives markets. The sharp rise in profitability coincided with the firm's intensified investment in local infrastructure, including the deployment of low-latency trading systems and expanded on-the-ground support teams. Trading volumes in Indian equities and currency futures increased by 312% and 287% respectively during the same period, contributing to the substantial gains. Regulatory authorities introduced new restrictions on foreign proprietary trading activities in early January 2026, prompting Jane Street to reassess its operational model in the region. The curbs, which limit the size of proprietary positions and mandate greater transparency in order routing, became effective immediately after the quarter’s close. Market participants noted that the pre-curb performance highlights the competitive advantage of high-frequency trading firms with deep technological integration in emerging markets. The sharp gain has prompted internal reviews at other global hedge funds evaluating similar expansions into India’s rapidly evolving financial landscape.
