Proprietary trading firms in India saw their aggregate derivatives profits drop to roughly $5 billion for the fiscal year ended in March, down from $7 billion the previous year.

In July 2025, SEBI temporarily barred US-based proprietary trading giant Jane Street Group from Indian securities markets over alleged market manipulation linked to the Bank Nifty index.

Indian retail traders suffered estimated losses of $12.5 billion during the same period, a 41% year-over-year increase.
