Commodity Price Trends - Gold prices initially surpassed $4500 per ounce before slightly retreating to $4485, marking a significant increase of over two-thirds this year [3][8]. - Silver prices rose nearly 1% to $72.11 per ounce, driven by both investment and industrial demand [11]. - Platinum prices reached a historical high above $2300 per ounce, influenced by supply shortages from major producing countries [14]. - London copper prices hit a record high, surpassing $12224 per ton [17]. - Chicago wheat futures continued to rise for five consecutive trading days, driven by supply concerns due to geopolitical issues and adverse weather conditions in the U.S. [18].
