India's SEBI Accuses Jane Street of Stalling Investigation by Demanding Excessive Documents
nashnova research
India's securities regulator SEBI accused Jane Street of delay tactics in court, as the quant giant faces a trading ban and a $503 million disgorgement order — the case's outcome will reshape how global quant firms assess regulatory risk in India.
What happened in court?
SEBI's lawyer Gaurav Joshi opened with a Hindi proverb meaning "the thief lectures the policeman" — implying Jane Street is trying to put the regulator on trial instead.
His core argument: SEBI only needs to share documents behind its interim order. Handing over more could compromise the ongoing investigation.
Joshi added that Jane Street has successfully stalled for a year and a half. Its real job is to explain why its trading strategy is not manipulation — not to challenge the regulator's process.
What is Jane Street accused of?
SEBI issued an interim order on July 3, 2025, banning Jane Street from trading on Indian securities markets and demanding disgorgement of ₹48.4 billion (roughly $503 million) in alleged illegal gains.
The core allegation: Jane Street manipulated pricing of stocks in the NSE Nifty Bank Index — one of India's most actively traded derivatives benchmarks — to rig the options contracts built on that index.
This means → SEBI believes Jane Street was not merely trading, but systematically distorting the pricing mechanism for profit.
How does Jane Street push back?
Jane Street cited reports from SEBI's own surveillance arm and the National Stock Exchange (NSE), claiming neither found evidence of manipulation.
SEBI's lawyer countered: the NSE report was "preliminary," and SEBI's earlier review was a "pre-investigation" stage — neither carries the weight of a final finding.
He also noted that NSE had sent Jane Street a warning letter, which the firm ignored. In plain terms = it is not that no one flagged the problem — Jane Street chose not to respond.
Why does this case matter?
Jane Street has deposited the full disputed amount into an escrow account, yet it still cannot trade in India — This means → even with the money set aside, the ban's freezing effect continues.
The outcome will directly shape how global quantitative trading firms assess regulatory risk in India's derivatives market.
Put simply = if SEBI wins, other quant giants will think harder about the real reach of cross-border enforcement before entering India; if Jane Street prevails, SEBI's enforcement credibility takes a hit.
