Hosted by Katie Martin and Robin Wigglesworth of the Financial Times & Pushkin Industries

Introduction

In the July 11, 2025 episode of Unhedged, hosted by Katie Martin and Robin Wigglesworth, the conversation delves into a recent scandal involving Jane Street—a prominent yet lesser-known trading firm. This episode unpacks the allegations of market manipulation in the Indian stock market, explores the inner workings of modern trading firms, and examines the broader implications for global financial markets.

Jane Street: An Overview

Katie Martin introduces Jane Street, highlighting its role and stature within the financial markets. Unlike traditional trading floors bustling with human activity, Jane Street operates with a minimal number of human traders, relying heavily on technology and algorithms.

"[...] these firms are like the world's biggest trading firms that don't have any human traders or have very few comparatively actual human traders doing this stuff." (04:41)

Robin Wigglesworth elaborates on Jane Street's operations, describing it as a market maker that facilitates buying and selling in the stock markets. He emphasizes the firm's significant growth, noting that its trading revenue soared from approximately $2 billion in 2018-19 to over $20 billion in the previous year.

"In the first quarter of this year, in fact, Jane Street made more money in markets than Morgan Stanley and within touching distance of Goldman, which has frankly been the powerhouse of financial markets for several generations now." (05:44)

The Indian Market Scandal

The core of the episode revolves around allegations made by the Indian stock market regulator against Jane Street. The regulator accused the firm of engaging in a sinister scheme to manipulate the market, resulting in the impounding of over half a billion dollars in what they termed as illegal gains.

Robin Wigglesworth provides context, explaining that Jane Street was accused of market manipulation through index arbitrage. The firm reportedly took large positions in Indian bank stocks and simultaneously shorted derivatives, particularly options. By dumping the stocks in a less liquid market, they artificially inflated the value of their substantial options positions, leading to significant profits.

"They took advantage of the fact that you had this massive, highly traded options market and this frankly, slightly decrepit, crappy actual stock market. And they made sure that those prices were more closely linked and they happened to make lots of money doing so." (12:24)

Notable Quote:

"It's all trading normally has an impact on the market. Are you manipulating that market? If I buy a stock of Apple, like realistically, it's going to have a very small impact." – Robin Wigglesworth (11:38)

Implications for Modern Trading Firms

The scandal shines a spotlight on the evolving landscape of trading firms. Robin Wigglesworth discusses how firms like Jane Street, Citadel Securities, Hudson River Trading, and others have become dominant forces in global markets, often surpassing traditional giants like Goldman Sachs and Morgan Stanley in trading revenue.

He highlights the intellectual allure of these firms, noting that internships at Jane Street are highly coveted and considered a mark of exceptional intelligence and prowess in the financial sector.

"Jane Street is the best of the best [...] having a Jane Street internship on your CV is a cool, sexy thing to have these days." (13:21)

Regulatory Scrutiny and Future Outlook

The allegations have sparked a debate on the thin line between sophisticated trading strategies and market manipulation. Robin Wigglesworth points out the gray areas inherent in trading practices, where actions taken to exploit market inefficiencies can sometimes be misconstrued as manipulative.

There is concern within the industry that this case might lead regulators to scrutinize other high-frequency and algorithmic trading firms more closely. While Jane Street maintains its innocence, the episode underscores the potential for increased regulatory interventions in the trading sphere.

"It's all a duck-rabbit situation [...] What they did was what they call index arbitrage." – Robin Wigglesworth (12:24)

Despite the significant role Jane Street plays in global markets, Robin Wigglesworth believes that even if Jane Street were to face severe repercussions, the presence of other large trading firms would prevent any catastrophic disruptions in the financial markets.

"There are enough rivals that would gladly see the back of Jane Street that would step in and pick up everything. So actually this wouldn't be a downfall happened by big financial catastrophe." (17:43)

Conclusion

The episode of Unhedged titled "The Secret Giant of Finance" provides an in-depth analysis of Jane Street's alleged market manipulation in India, shedding light on the complexities and challenges of regulating modern trading firms. Through engaging dialogue and expert insights, Katie Martin and Robin Wigglesworth navigate the intricate balance between innovative trading strategies and the ethical boundaries that govern financial markets.
