Why the blocked amount is unchanged after modifying an IPO bid

The blocked amount staying unchanged after an IPO bid modification is a recurring source of confusion, and in almost every case it is one of two things: the new UPI mandate has not yet been approved, or the modified bid does not require more money than is already blocked. The block is a lien placed on your bank account by the UPI ASBA mandate, valued at the bid quantity times the upper end of the price band , and it changes only when a new mandate raising that value is authorised. A modification that lowers the bid, or one whose new value is already covered, leaves the existing block in place.
