The stock of Rio Tinto (NYSE: RIO) has lost more than 5% in the previous month and is now trading at little under $84 per share. During this time, commodities prices were often sluggish, which contributed to the drop. Metals prices had previously soared in response to China’s strong recovery following the pandemic, and authorities suspect that speculative activities are being used to maintain prices high. As a result, China has said that it will crack down on stockpiling and monopolies while focusing on attempts to bring commodity prices down. China’s National Food and Strategic Reserves Administration has declared that metal from its stockpile will be released in phases in the near future. In addition, despite Republican resistance, US President Joe Biden has recommended reducing his spending proposal from $2.25 trillion to $1.7 trillion. This has caused instability in global commodities markets, causing some of the world’s largest mining companies, such as Rio Tinto, to lose value. Will RIO stock continue to fall in the coming weeks, or is a rebound more likely?
