Nixon's decision to abandon the Gold Standard in 1971 shifted the US dollar to a fiat system, allowing more flexibility but potentially weakening trust in its long-term value. Now, the BRICS nations are pushing for alternatives, aiming to reduce reliance on the dollar, which has led to geopolitical tensions and economic shifts. I see this as part of a broader trend of diversification and attempts to regain economic sovereignty, especially in emerging markets. The US dollar's dominance is being challenged by these alliances, signaling changes in global power dynamics.
