Rio Tinto stock (NYSE: RIO) has dropped more than 11% in the last one month and currently trades at $76 per share. The recent drop in the stock has been driven by a sharp decline in global iron ore prices. Iron ore price per dry metric ton dropped almost 35% from more than $220 in July 2021 to less than $145 at the beginning of September 2021, mainly due to lower imports by China following its move to control steel production to meet carbon emission norms. China had asked 20 steel mills in Tangshan city to suspend operations for a week in August in order to reduce emissions as the Chinese steel sector makes up 15% of the country’s total carbon emissions. Also, China’s iron ore imports dropped to 88.51 million metric tons in July 2021 compared to 89.41 million metric tons in June 2021. This was much lower than the 102.1 million metric tons recorded in March 2021. With efforts to control steel production, the demand for the key raw material – iron ore – from China has been hit severely leading to a sharp drop in price levels. However, there has been a slight recovery with Chinese iron ore imports coming in at 97.5 million metric tons in August 2021.
