Jane Street’s Market Manipulation Tactics Revealed in Indian and Crypto Markets

Jane Street’s financial operations have come under scrutiny due to numerous allegations that suggest their business model is designed to manipulate markets and profit from artificial crashes. This is not an isolated incident, as multiple instances of such behavior have been reported.

One clear example of Jane Street’s modus operandi is demonstrated in their activities in the Indian stock market. They utilized an algorithm that mimicked a market crash at 10 a.m., generating a staggering $4.23 billion in profits before being caught and temporarily banned by the Securities and Exchange Board of India (SEBI).

The intricacies of how Jane Street manipulated the market are quite fascinating. Between January 2023 and March 2025, Jane Street amassed approximately ₹365.02 billion in net gains through their operations in India. SEBI identified ₹48.4357 billion of this as suspected illegal proceeds, leading to a trading ban and the deposit of disputed funds into an escrow account pending further investigation.

The ban itself is not the crux of the matter; rather, it is the underlying mechanisms at play that are of concern. Jane Street operates through a complex web of entities, including Jane Street Singapore Pte Ltd, Jane Street Asia Trading Ltd, JSI Investments Pvt Ltd, and JSI2 Investments Pvt Ltd, allowing them to separate their visible trading activities from their profitable ventures.

One method employed by Jane Street involves manipulation of expiration dates. By strategically buying and selling stocks and futures related to key indices, they create scenarios where fluctuations in the index value on expiration dates result in significant gains from options trading. SEBI details the strategy, describing how Jane Street’s Indian entity would engage in heavy buying during the morning session, driving up the index, only to reverse their positions in the afternoon, causing the index to drop and profiting from options trading.

The same tactic of triggering market movements to capitalize on derivative positions was observed in the case of Bitcoin. At 10 a.m. Eastern Time, significant selling pressure was consistently applied, leading to forced liquidations of leveraged long positions and subsequent market stabilization. This strategy exploited the high leverage in the cryptocurrency market to create cascading effects of price drops and subsequent rebounds.

The collapse of Terra’s UST stablecoin and the subsequent lawsuit against Terraform Labs shed light on another aspect of market manipulation. Allegations suggest that Jane Street may have exploited the liquidity crisis surrounding UST to acquire Bitcoin reserves at discounted prices, further weakening Terra’s position and potentially profiting from the turmoil.

In conclusion, the intricate web of financial manipulation orchestrated by Jane Street, particularly in markets like India and cryptocurrency, highlights the need for greater regulatory oversight to prevent such exploitative practices. The revelations surrounding their activities serve as a cautionary tale about the complexities and risks inherent in the world of high-stakes finance.
