How did SEBI uncover Jane Street's ₹36,500-crore scam?
SEBI banned Jane Street from Indian markets for allegedly making illegal gains totalling ₹36,500 crore. This followed 15-month-long trail of regulatory scrutiny, caution letters and firm's repeated disregard. SEBI's probe into the firm's trade was triggered by media reports referencing a legal dispute. It observed abnormally high or low volatility on weekly index options expiry days during probe.
