The collapse of the Bretton Woods system in 1971 led to the end of the gold standard, with the US dollar devaluing and the introduction of floating exchange rates. The US turned to oil as a new value anchor through the 1974石油美元协定. Gold, no longer used for currency valuation, became a stable store of value. The 1976牙买加协议 marked the beginning of its non-monetary status and fueled a surge in gold prices, making it a key driver of price fluctuations in the international market.
