India: BigMint’s billet index rises INR 150/t despite limited buying – 21 July

  • Raw material prices firm up, support billet tags
  • Finished steel demand remains weak in Raipur

BigMint’s billet index increased by INR 150/tonne (t) d-o-d, settling at INR 36,700/t exw-Raipur on 21 July 2025. The upward trend was primarily driven by continued raw material cost pressure, even as buying activity in the semi-finished steel segment remained subdued.

Spot offers in the billet market moved up slightly, supported by firming up of iron ore and sponge iron prices. However, finished steel demand stayed subdued, with a significant gap between billet procurement and finished steel sales.

Commodity snapshots

  • Rebar: Prices stayed range-bound amid cautious sentiments.
  • Wire rod: Prices dropped by INR 100/t with approximately 1,600 t of deals concluded.
  • Sponge iron: Prices increased by INR 150/t backed by supply tightness and rising input costs.

The conversion spread from sponge iron (PDRI) to billets in the Raipur induction furnace steel hub narrowed further to INR 12,850/t, squeezing margins of producers due to rising input costs.
