Fastmarkets’ iron ore value-in-use adjustments for iron, silica, alumina and phosphorus are currently weekly indices with a data inclusion cut-off time each Friday at 6pm Singapore local time, and a publication time each Monday at 6.30pm Singapore local time. The chemistry adjustments represent the market-implied value of individual chemistries, calculated from a regression-based analysis of the previous week’s transaction and non-transaction data.

Fastmarkets proposes to increase the publication frequency of its value-in-use indices to daily. They will be calculated and updated every Monday based on a regression analysis using the previous week’s data, before remaining flat from Tuesday to Friday. The proposed daily publication will make it easier for market participants to apply the value-in-use indices to Fastmarkets’ other daily indices. The unchanged calculation method will ensure sufficient liquidity and data points remain for a robust regression-based analysis.

The proposed increase in frequency will be applicable to following indices:
  • Iron ore 62% Fe fines, % Fe VIU, cfr Qingdao, $/tonne MB-IRO-0018
  • Iron ore 65% Fe fines, % Fe VIU, cfr Qingdao, $/tonne MB-IRO-0019
  • Iron ore 62% Fe fines, % Si VIU, cfr Qingdao, $/tonne MB-IRO-0020
  • Iron ore 62% Fe fines, % Al2O3 VIU, cfr Qingdao, $/tonne MB-IRO-0021
  • Iron ore 62% Fe fines, 0.01% P VIU, cfr Qingdao, $/tonne MB-IRO-0024
The consultation period for this proposed frequency increase starts from Monday September 13 and will end on Friday October 29. The change will take place, subject to market feedback, on Monday November 1.
