PRICE ASSESSMENT
Platts Iron Ore Index (IODEX) Price Assessment
The world's most-referenced iron ore price index, since 2008.
What is the Iron Ore Price Index (IODEX)?
The iron ore price index is a daily spot price assessment that reflects the tradeable market value of iron ore fines delivered into China. It is expressed in US dollars per dry metric tonne ($/dmt) on a cost-and-freight (CFR) basis to Qingdao, the primary delivery point for seaborne iron ore imports into China.
The most widely used iron ore price index globally is the Platts IODEX (symbol: IODBZ00), published by S&P Global Energy. IODEX is based on a standard specification of iron ore fines with 61% iron (Fe) content. It serves as the primary pricing reference for the seaborne iron ore market and underpins a broad range of spot trades, long-term contracts and financial derivatives including iron ore swaps and futures.
