Equities of prominent capital market institutions and brokerage entities recorded gains of up to 3% following a regulatory circular issued late on a Thursday evening. The policy update focuses on the closing auction session mechanism across domestic trading platforms.
Global financial analysis providers noted that the updated regulatory structure aims to decrease volatility specifically on contract expiry days. Market observers pointed out that while order volumes for certain brokers remain below historical metrics, exchange turnover has recovered.
The market authority previously established the closing auction framework in January to enhance price discovery transparency. Following a review period, the regulator published a consultation paper that attracted more than 20,000 public responses.
The restructured ten-minute session will function daily from 3.30 pm to 3.40 pm, structured into three distinct phases. Implementation timelines vary, with most adjustments taking effect on December 7, 2026, and specific order-transfer protocols scheduled for February 8, 2027.
Operational modifications include revised calculation methodologies for derivative settlement prices utilizing volume-weighted average metrics over the final half-hour of continuous trading. Additionally, pending orders from continuous sessions will transition into the auction under newly defined priority rules.
Stock exchanges and clearing houses must now update their operational procedures in alignment with the regulator within a seven-day window. Institutions are also required to deploy necessary technological architecture to support the transition.
