The Securities and Exchange Board of India (Sebi) is proposing significant cuts to mutual fund brokerage fees, aiming to reduce investor costs. Cash market brokerage could drop from 12 to 2 basis points, and derivatives from 5 to 1 basis point. To assess this, the Association of Mutual Funds in India (Amfi) is collecting 10 years of transaction data from fund houses. This aims to prevent investors from double-paying for research and control trading expenses, with the feedback deadline extended to November 24.
