Understanding the high-grade iron ore market

2021-3-26  Iron ore is a complex commodity made up of a spectrum of different product grades and forms. Conventionally, the 62% Fe sinter fines benchmark is commonly referred to as a simple proxy for iron ore prices overall but in reality most products in the market will fetch different prices based on their individual value-in-use. As well, the price relativities of higher- and lower-grade ores, or of lump or pellet, are highly variable in response to changes in market conditions over time. This section delves into the factors that drive the volatility in price differentials between different iron ore grades
