The capital markets regulator, the Securities and Exchange Board of India (Sebi), has revised the cut-off timings to determine the net asset value (NAV) when repurchasing or redeeming units in overnight mutual fund schemes. The changes are set to take effect from June 1, 2025 onwards. The regulator had said in its circular dated December 12, 2023, that this revision will allow stock brokers and clearing members to “un-pledge units of overnight schemes and place repurchase or redemption request with mutual funds, after the close of market hours.”
