Gold prices declined as the US dollar strengthened following President Trump's announcement of a new 10% tariff targeting BRICS nations. This move, amid geopolitical tensions and ongoing trade negotiations, caused gold to fall by 0.8% to around 3311 dollars per ounce. Despite recent drops, gold remains up over 25% this year due to ETF inflows and central bank demand. Trump also warned of further tariffs if BRICS countries develop their own cross-border payment system, which could impact global markets and the dollar.
