币界网报道：The U.S. dollar is confronting unprecedented challenges as global economic dynamics shift, with potential policy changes threatening its long-standing dominance. Analysts highlight increasing pressure from alternative reserve currencies and digital assets, while geopolitical tensions and trade realignments further complicate the dollar's stability. Central banks worldwide are diversifying reserves, reducing dollar exposure amid concerns over U.S. fiscal policies and inflation risks. Meanwhile, the Federal Reserve's potential pivot in monetary strategy could weaken the greenback's appeal. Market watchers warn that sustained dollar depreciation may trigger capital outflows and higher import costs, though some argue a softer currency could boost exports. The evolving landscape underscores growing uncertainty around the dollar's future role in global finance.
