Changes in supply and demand, macroeconomics, etc. The fluctuation of iron ore futures price is influenced by many factors, including market supply and demand, macroeconomic situation and so on. If the market supply increases or the demand decreases, the price of iron ore may fall, and some large iron ore producers increase production, resulting in oversupply in the market, which leads to price decline. Macroeconomic factors such as domestic and international economic situation and inflation level also affect iron ore prices, leading to fluctuations in commodity prices.
