Regulatory Changes

The price band mechanism is a surveillance tool used by BSE to control excessive volatility in securities. By revising price bands:

  • Trading in affected securities will be restricted to the specified percentage movement (up or down) from the previous closing price
  • Tighter bands (1-5%) indicate higher concern about price manipulation or excessive speculation
  • Wider bands (10-20%) allow greater price discovery while maintaining some control
  • This is part of BSE’s ongoing surveillance and market integrity measures

Compliance Requirements

  • Trading members must adhere to the revised price bands for all 36 listed securities
  • Orders exceeding the price band limits will be rejected by the trading system
  • Members should update their risk management systems and inform clients about the revised bands
