SEBI’s CAS Rollback Offers Lifeline to Indian Derivatives Market

SEBI’s Rollback of CAS: A Game Changer for India’s Derivatives Market

The recent decision by SEBI to revert to the volume-weighted average price mechanism for derivative settlements could revitalize India’s struggling equity-derivatives market.

Understanding the CAS Rollback

SEBI’s recent rollback of the closing auction session (CAS) mechanism, which was introduced on August 3, has been met with relief from market participants. The regulator will now revert to using the volume-weighted average prices (VWAP) of underlying stocks during the last 30 minutes of continuous trading for settlement on expiration days. This change is expected to reduce the chaos that characterized the market during the CAS period, where price swings became rampant, leading to a significant decline in trading volumes.

Market Implications of the Change

The return to the VWAP system is anticipated to restore clarity and predictability around expiry settlement prices. Dhiraj Relli, managing director of HDFC Securities, emphasized that this move could help rebuild trader confidence and reduce uncertainty-driven trading behaviors. This is particularly significant given that the average daily turnover in equity derivatives had plummeted to an 18-month low following the introduction of the CAS.

Market analysts from Jefferies Financial Group have noted that the rollback could lead to a gradual increase in trading volumes, especially in options and futures. The more predictable settlement mechanism may encourage traders to resume strategies that were disrupted by the CAS, potentially lifting transaction revenues for brokers and exchanges.

Benefits for Brokers and Traders

The rollback is expected to particularly benefit brokers, as lower volatility on expiration days could lead to increased order volumes. Analysts suggest that proprietary trading desks may find it easier to manage expiry risks, while arbitrageurs could benefit from a more stable environment for executing hedging and arbitrage strategies. This shift could attract back traders who had previously stayed away due to concerns over unpredictable settlement prices.

Eshaan Lazarus, CEO of broker 021 Trade, pointed out that the lower liquidity during the CAS period allowed smaller participants to influence closing prices, particularly in thinly traded instruments. The return to the VWAP system is expected to mitigate such swings, making the market more predictable and accessible for a broader range of traders.

Looking Ahead: A Recovery on the Horizon?

As the derivatives market begins to stabilize, market participants are cautiously optimistic about a recovery. The rollback of the CAS mechanism is seen as a crucial step in restoring confidence and encouraging trading activity. While SEBI’s efforts to curb speculative trading remain in place, the expectation is that this change will help revitalize the market and bring volumes closer to pre-CAS levels over time.
