The Securities and Exchange Board of India (SEBI) has initiated strict proceedings against two entities following allegations of price manipulation in the Sensex Cash Settlement (CAS) process during expiry.

  • SEBI has targeted two entities regarding suspicious price spikes in the Sensex CAS.
  • The investigation revealed artificial price surges through three large orders on expiry day.
  • The regulator aims to protect market integrity and prevent unfair gains.

In a decisive move to safeguard the integrity of the Indian capital markets, the Securities and Exchange Board of India (SEBI) has launched a major investigation into alleged manipulation within the Sensex Cash Settlement (CAS) mechanism. The action follows reports of irregular trading patterns observed during recent index expiry sessions.

According to regulatory findings, a significant 'price spike' was detected in the CAS during Sensex expiry. This surge was reportedly driven by three massive orders that appeared to deviate from standard market volatility. SEBI is currently scrutinizing the involvement of two specific entities suspected of orchestrating these movements to gain an unfair advantage.

Why This Matters

BozokMedia analysis shows that any perceived weakness in the settlement process of a benchmark index like the Sensex can have far-reaching consequences. Such manipulations not only jeopardize retail investor wealth but also threaten the global reputation of India as a transparent and stable investment destination.

Ensuring the sanctity of the settlement process is paramount to maintaining investor confidence in the derivatives segment.

Historically, SEBI has maintained a zero-tolerance policy toward market abuse, particularly involving algorithmic irregularities and high-frequency trading tactics. To further bolster market stability, the regulator is also looking into expanding the scope of SLBM (Stock Lending and Borrowing Mechanism) to provide a more robust framework for cash settlements.

While SEBI has emphasized that the CAS process must not be unfairly maligned, the regulator remains committed to uncovering any systemic vulnerabilities. This crackdown serves as a warning to market participants that the era of exploiting expiry-day volatility through coordinated large-scale orders is being met with unprecedented regulatory scrutiny.
