The read

BSE has given its Designated Market Makers more breathing room. For SENSEX, BANKEX, and Focused IT Index Futures, the maximum permissible bid-offer spread has been increased from 0.10% to 0.25% of the bid price. The move eases the quoting obligation on DMMs, especially in volatile conditions, but comes at a cost: end-investors face wider spreads. This is a moderate operational adjustment, not a structural shift. All other DMM provisions remain intact.
