Quick answerRBI has revised the minimum bidding requirement for Primary Dealers in Additional Competitive Underwriting auctions from 3% of notified amount to an amount equal to each PD's Minimum Underwriting Commitment, effective henceforth.

What changed

Previously, each PD had to bid for at least 3% of the notified amount in the ACU auction. Now, the minimum bid in the ACU auction is set equal to the PD's MUC, which is a fixed rupee amount based on the total MUC divided equally among PDs.

What it means for you

This change aligns the ACU minimum bid with the MUC, reducing the total underwriting commitment for all PDs from 5358 crore to 5016 crore in the illustration. It simplifies bidding requirements and may lower the aggregate risk for PDs, as the minimum bid per PD decreases from 150 crore to 132 crore in the example.

What you must do

What is the new minimum bid amount for a PD in the ACU auction?
