白宫关门那日，中国突然停买美元铁矿，全球市场懵了！

Core Viewpoint - China is shifting its iron ore purchasing strategy by indicating it will no longer buy from BHP in US dollars, suggesting a move towards using the Chinese yuan for transactions, which reflects a broader strategy to reduce reliance on the US dollar in international trade [1][4]. Group 1: China's Strategy - China has been gradually decreasing its purchases of US Treasury bonds and is now extending this strategy to iron ore, which is critical as over 70% of its iron ore needs are met through imports [4]. - BHP is the largest supplier of iron ore to China, and controlling iron ore prices is crucial for the steel industry, indicating that this move could significantly impact pricing dynamics [4]. Group 2: Market Reactions and Implications - Despite concerns, the majority of global iron ore transactions (85%) are still conducted in US dollars, with the yuan accounting for less than 5%, suggesting that the transition may face challenges [5]. - The Australian market, particularly BHP, has not reacted severely to the news, indicating that supply chains remain intact while awaiting China's next steps [5]. - This initiative aligns with China's long-term goal outlined in a 2025 government white paper to promote the use of the yuan in commodity pricing, potentially leading to a shift in pricing power from established indices to China [5].
