Regulatory Changes

Price bands are circuit filters that limit the maximum intraday price movement of a scrip. Revisions to lower bands (e.g., from 20% to 5%) restrict volatility and are typically applied under BSE’s surveillance framework (including ESM/GSM measures). The revised bands replace the existing levels for each listed scrip.

Compliance Requirements

• Trading Members: Must note the revised price bands and ensure order placement complies with the new limits from May 19, 2026 onwards
• Risk Management Systems: Firms should update their systems to reflect the new circuit filter levels for affected scrips
• No action required from listed companies directly

Important Dates

• Notice Date: May 18, 2026
• Effective Date: May 19, 2026

Impact Assessment

The tightening of price bands to 5% or 2% for most scrips signals heightened regulatory scrutiny under BSE’s surveillance mechanism. Traders holding positions in these scrips will face restricted intraday movement, reducing speculative activity. Dynamic Cables Ltd is an outlier with a wider 10% band, possibly reflecting a relaxation from a more restrictive prior band.
