Key updates
Bids decline against last auction: Bids for Mn30-32% lumps were at INR 9,690/t ($113/t) in the auction on 5 April, compared to bids on 12 March, which stood at INR 9,960/t ($116/t), down by 3%.
However, bids for Mn20-22% grade were at INR 2,920/t ($34/t) in the latest auction, unchanged from the previous auction. During week 14, silico manganese prices declined by INR 220/t ($3/t), reaching INR 72,280/t ($842/t) exw-Vizag compared to INR 72,500/t ($845/t) in week 13. This decrease likely influenced the dip in bid prices.
Bids remain firm against base prices: In the recent auction, base prices and bids remained stable. For instance, the base price of Mn20-22% lumps was INR 2,920/t ($34/t), while the weighted average of bids for the same remained firm.
Similarly, the base price of Mn18-20% was INR 2,520/t ($29/t), while the weighted average of bids was the same. Another grade of Mn30-32% revealed the same pattern, with the base price at INR 9,690/t ($113/t) and the bid price at the same level.
This month’s stable bids stem from need-based purchases, strategic procurement, and year-end fiscal activities, as players focus on finalising their financial records.
