最新报道:Economist Barry Eichengreen expresses skepticism about the feasibility of a BRICS currency by 2026, citing persistent challenges to dollar dominance. Russia proposed a blockchain-based payment platform using central bank digital currencies to bypass the U.S. banking system, though governance and regulatory issues remain unresolved. A gold-backed strategy faces practical hurdles, such as high transaction costs and limitations reminiscent of the gold standard. Previous attempts to rival the dollar, including the euro and renminbi, have struggled due to structural and governance constraints. BRICS members acknowledged the need for monetary system improvements but set no concrete timeline for a common currency.
