Introduction

The securities market in India has become systematically important and dominantly retail in  aspects and is now the center of risk transfer and price discovery. It leads us to a well-known case  which occurred in 2012 amidst the streets of London and one of the questions most frequently  posed today as to how we keep liquidity without introducing the failure modes that created the  infamous so-called London Whale at JP Morgan (“Whale”) where it remains the best illustration  of where ambiguous so-called portfolio hedging and laissez-faire optimistic valuation in thin  markets. With Parliament thinking about the Securities Market Code, 2025 (“SMC”) and with  surveillance being remodeled by the Securities and Exchange Board of India (“SEBI”) in equity  derivatives, we have a chance to study and internalize it into law and supervisory practice. 

What happened with the CIO? 

Outsizing synthetic credit positions, the Chief Investment Office, London desk of JP Morgan sold  an unprecedented number of credit default swaps (“CDS”) in a brief period of time at a stress point  to defend the book. Value at risk (“VaR”) model was modified by traders such as Bruno Iksil such  that they understated risk, accepted the repeated excision of risk limits as measurement artifacts  which almost caused losses of up to 6 billion USD. This was described by the Commodities Futures  Trading Commission as reckless under Dodd-Frank §6(c)(1) and Rule 180.1, and resulted in a  penalty of $100 million, with confessions to named facts, in the first settled case by the agency  under its post crisis anti manipulation authority. In parallel, coordinated U.S. and UK settlements  of approximately 920 million faulted (i) a VaR model change that underpriced exposure, (ii)  multiple instances of risk limits being breached explained as artefacts, and (iii) valuation controls  condoning picked marks on broad spreads. The final notice of UK’s Financial Conduct Authority is explicit on governance failures from the desk through senior management.  

The Whale re-shaped the U.S Doctrine as it added the Volcker Rule in which it tightened the  exemption in risk mitigating hedging by requiring that a hedge be explicitly linked to a particular,  quantifiable risk when it is established. It should also be periodically reviewed as circumstances  evolve and backed up with an in-depth documentation that it is actually meant to mitigate risk and  not to take advantage of the profit opportunities. Indian jurisprudence also tends in the same way.  Whether a position lowers risk in fact, not by name and that is the norm of our exchanges, clearing 

corporations, and brokers can observe when we insist on the right artifacts. Justice Kurian in SEBI  v. Rakhi Trading, pointed out the parity, integrity and transparency as the litmus test to Prohibition  of Fraudulent and Unfair Trade Practices (“PFUTP”) in securities market demonstrable market  wide price impact is not necessary when trading is detrimental to a fair market. This is in line with  the emphasis on conduct and controls of the Whale authorities. 

Indian Regulatory Movement 

The SMC arrives at a very opportune time as on 18th December 2025 it was tabled in Lok Sabha  and referred to the standing committee, it aims to consolidate The Securities and Exchange Board  of India Act, Securities Contract Regulation Act and Depositories Act to unify and modernize  India’s securities laws so that regulation becomes clearer, faster, and more coherent especially in  investigations, adjudication, governance, and market integrity. This organizational simplification  is capable of bringing down procedural fragmentation cases in market-abuse cases without  compromising the due process. These measures, with the Code and in parallel to SEBI 2024  circular upgrading stress-testing regime of equity derivatives core Settlement Guarantee Fund  (“SGF”) and the introduction of filters such as filtered historical simulation using exponentially  weighted moving average to stabilize index-derivative microstructure which will be followed by  2025 circular where SEBI introduces the package to strengthen risk monitoring and disclosure of  equity F&O. Taken together, these steps amount to a realistic path to “Whale-proof” our markets  without chilling legitimate hedging and liquidity provision. 

Whale Lessons For Indian Law And Microstructure 

VaR methodology which minimized measured risk in the middle of the crisis with no mechanism  of strong validation was tolerated in the Whale-era and is a textbook case of model drift. The Indian  analogue is where SEBI purchased the modifications associated with stress testing and the sole  lacking connection is a member-level model-change protocol. Any change of pricing or risk model  that reduces measured exposure by over 25% or switches breach to compliance would be subject  to a 90-day parallel run with T+1 notification to MII (Market Infrastructure Institution) risk and  temporary concentration add ons until independent validation clears. This aligns with the spirit of  exposing tail risk and then the reduction in capital cover.

Second, India ought to seal the escape hatch of a “portfolio hedge” by embracing a documentary  discipline because Volcker tightened hedging by insisting on a particular risk connection and  persisting effectiveness and it does not require a structural prohibition to achieve the same result.  MIIs may need a file of risk-factor mapping of ex-ante hedge effectiveness, correlation windows  and scenario ladders and periodic checks. When the book begins to create asymmetric P&L which  is not related, then it could be stated as proprietary with regards to risk with stricter margins and  limits.  

Third, valuation in illiquidity needs codified prudence. One lesson from the Whale was how easy  it is to pick a mark inside wide spreads to dampen reported losses, particularly when liquidity is  episodic and the trader’s book dominates the order book. The FCA results on valuation controls,  coupled with the U.S. settlements that refer to inadequate internal accounting controls, highlight  the fact that boards should look behind the scenes of the price formation in the concerned venue.  Indian implementation can be easy since it would need independent price sources or liquidity  valuation adjustments (“LVAs”) every time there are two-sided quotes, but concentration reserves  where a member has a large portion of open interest or displayed depth and request quarterly audit  committee certification of valuation procedures of illiquid derivatives books. 

Fourth, senior-manager accountability must become visible in derivatives risk and valuation. The  Senior Managers & Certification Regime in the UK refined the line of sight between the function  and individual, so that it is clear who is to do what. India is not required to transplant certification  on wholesale basis but the conflict of interest and governance provisions of SMC allow a pragmatic  equivalent since it demands significant derivatives intermediaries to submit named responsibility  statements of market risk and valuation, which have an escalation obligation. Lack of compliance  should be punishable as an act of conduct violation and not a failure of procedure only.  

At the microstructure level, a mass dump is overwhelming the legitimate supply and demand and  thus we must have market-infrastructure guardrails that prevent this defensive dumping becoming  a strategy. Exchanges should run Indian trades via SMC should incorporate dynamic concentration  bands based on top five participant open interest, throttle order to trade ratios when bands are  violated, and pre announce closing auctions in case of top of book depth collapses particularly now  where options market now is dominated by short tenor contracts and expiry day spikes.

Lastly and most crucial adjudication at trading speed. The SMC isolates inspection, investigation  and adjudication, specifies who may be an officer and directs disgorgement/restitution to injured  investors and this framework must be supplemented by a regulatory obligation to issue transparent,  well-grounded, orders written in plain language that quantify illegal gain or harm and sanctions  that relate to governance failures. The NSE co location proceedings must be mentioned in any  discussion of surveillance and due process in India when in September 2024, SEBI dismissed charges against the exchange and seven former officials, although it continued to prosecute a  broker which was an outcome underscoring the importance of evidentiary standards and reasoned  adjudication to lasting outcomes. The moral of the story is not that the surveillance overstepped  the mark, but that the discipline of a process is important by addressing issues that are objective in  architecture, explicitly testing the hypotheses of benefits or conspiracy, and reporting the findings  in a way that can withstand scrutiny in an appeal. By providing role clarity and role conflicts  protection through codification, a consolidated Code can provide precisely that. 

Conclusion

Where does this leave boards, risk committees, and desk heads in practice? They should consider  any paperwork as possible evidence at a later stage. When the change in models reduces the  measured exposure, the reasoning ought to be documented prior to the change. The evidence on  the effectiveness of hedges in reducing risk, and periodically revalidating the hedge should be  supported. As liquidity becomes weak, valuation should be based on independent data and reserves  need to be defensible in front of an audit committee that is knowledgeable on liquidity stresses.  Where position size connotes market effect, dynamic limits and auction should be anticipated to  be automatic. These practices do not belong to the administrative load, but the working part of the  promise of India to good market practices.  

The London Whale was never a scandal rather it was an evidentiary look about how complex  books fail. The securities policy path of India after 2024 demonstrates that we have learned the  technical lesson, and it will become even stronger as the SMC approaches and provided that the  discipline of the model-change is coded the derivatives market will flourish when the size will be  sensibly reflected by a market-mechanism and no longer will there be any nuisance of the size. We  can retain India as one of the most liquid derivative destinations in the world without having to 

imbibe the infirmities of the Whale where it is not going to be statue upon mere governance  account but a foundation of trust in the market.
