The road between arbitrage and market manipulation has lengthy been one of many grayest areas in monetary markets — and India’s current motion in opposition to high-frequency buying and selling large Jane Avenue has introduced this murky boundary into sharp focus.
Arbitrage, at its core, is like recognizing a mismatch and making an attempt to make a revenue out of it — and it’s completely authorized. It refers back to the simultaneous shopping for and promoting of an asset in several markets to use value variations.
Market manipulation, against this, is an unlawful act designed to deceive or distort the free and truthful operation of markets — sometimes by influencing costs or deceptive appearances of provide and demand for unfair benefit.
However when does arbitrage edge into illegality?
Based on consultants whom CNBC spoke to, the excellence hinges on intent and market affect.

On July 3, India’s Securities and Change Board (SEBI) quickly blocked Jane Avenue Group from collaborating within the nation’s securities markets, accusing the U.S. high-frequency buying and selling agency of large-scale market manipulation. This contains ways to govern India’s Nifty 50 index in an effort to revenue from sizable positions in index choices.
Based on SEBI’s 105-page interim order, the agency allegedly purchased giant volumes of shares and futures tied to the Nifty Financial institution Index, which tracks the efficiency of India’s banking sector, throughout the early hours of buying and selling. It then positioned vital wagers anticipating a decline within the index later within the session.
SEBI added that Jane Avenue subsequently bought off these earlier purchases, pushing the index decrease and growing the profitability of its choices positions. The regulator argued that this was a part of a “deliberate technique to govern indices” for the good thing about its bigger and extra profitable choices bets.
SEBI stated that the depth and sheer scale of the intervention, coupled with the fast unwinding of positions “with none believable financial rationale,” was deemed manipulative.
Jane Avenue disputed the findings of SEBI’s interim order, informing staff in an inside electronic mail that it deliberate to problem the ban whereas claiming that its actions have been “fundamental index arbitrage buying and selling.”
The buying and selling agency would later deposit $567 million into an escrow account on July 14, as directed by SEBI, not earlier than requesting permission to renew buying and selling within the nation and the lifting of restrictions.
The important thing: mens rea
Because the authorized back-and-forth commences, business veterans stated the distinction between authorized arbitrage and unlawful manipulation is not all the time clear-cut.
The intention behind wrongdoing in trades — referred to as mens rea, which suggests “responsible thoughts” in Latin — is vital to figuring out manipulation, stated Pradeep Yadav, finance professor on the College of Oklahoma. He additionally identified that creating an arbitrage alternative by influencing costs in a much less liquid market is what crosses the road into illegality.
“Arbitrage turns into market manipulation if you end up creating the arbitrage by manipulating the much less liquid facet of the market,” he stated, explaining that the choices market in India may be very liquid due to the massive quantity of consumers and sellers. Nevertheless, the nation’s spot and futures markets are much less so, which renders it simpler to push costs by inserting giant sufficient trades.
This sort of arbitrage, whereas aggressive, is authorized and sometimes useful to market effectivity.

SEBI’s case hinges on two claims. First, Jane Avenue deliberately distorted the much less liquid money market to revenue on the extra liquid choices market. Certainly, SEBI, in its interim order in opposition to Jane Avenue, cited an earlier judgement from a case, “No person deliberately trades for loss. An intentional buying and selling for loss per se, will not be a real dealing in securities.”
Second, that its income got here solely from choices, with constant losses in shares and futures, suggesting the trades have been designed to maneuver costs slightly than replicate real market views.
“Mens rea is the demonstration of in poor health intent to govern the market… if costs are already misaligned, arbitraging them is okay. However should you’re the one pushing costs out of alignment — particularly in much less liquid markets — to revenue on the opposite facet, then that is manipulation,” stated the professor, who added that in a standard arbitrage state of affairs, the dimensions of 1’s inventory commerce and their choices commerce could be proportional. The imbalance, in his view, steered it was not a case of basic arbitrage.

Different consultants additionally emphasised that the fantastic line between market manipulation and arbitrage lies in intent.
Nevertheless, V Raghunathan, a former SEBI major market board member, believes that Jane Avenue’s actions have been inside the authorized realm. Jane Avenue thrives in exploiting minute inefficiencies — for instance, in ETF pricing versus underlying securities, or between exchanges, he stated.
“This sort of arbitrage, whereas aggressive, is authorized and sometimes useful to market effectivity,” he informed CNBC.
He cited the instance of latency arbitrage — the place corporations revenue from tiny time delays in market knowledge throughout venues — as being criticized as parasitic or predatory, however hardly unlawful.
That stated, Raghunathan famous that the broader concern is whether or not Jane Avenue’s methods got here near manipulation — in both intent or the letter of the regulation.

Like different consultants whom CNBC spoke to, Raghunathan established market manipulation as intentionally deceptive or influencing costs and buying and selling volumes to create synthetic tendencies or unfair benefits, reminiscent of pump-and-dump schemes and wash buying and selling.
“In brief, until Jane Avenue is discovered to be inserting misleading orders, like spoofing, abusing confidential data, or manipulating costs to create synthetic strikes — none of which it has been accused of — it might not be thought of to have engaged in market manipulation,” he stated.
Paul Rowady, director of analysis at Alphacution Analysis, stated that the strains between manipulation and arbitration additionally rely on the regulator’s tooth. Within the U.S., comparable allegations would hinge on whether or not a agency engaged in spoofing or deception.
“Buying and selling aggressively will not be a criminal offense,” he stated.
Market watchers additionally echoed that the Jane Avenue case spotlights the vulnerabilities of India’s market construction — together with liquidity imbalances between spot and choices markets — which refined gamers can legally exploit however which regulators could now search to tighten.

As a former U.S. SEC litigator, Howard Fischer places it, arbitrage is akin to ” one’s neighbor’s home, seeing he retains stacks of newspapers and lit candles in all places, and taking out fireplace insurance coverage on his house.”
“Manipulation is giving him a July 4th current of firecrackers and propane tanks,” Fischer, who’s now a associate at regulation agency Moses & Singer, stated.
The excellence lies in intent: arbitrage exploits inefficiencies; manipulation tries to fabricate them.
