[international rating agency Moody's report: U.S. debt crisis and abuse of sanctions threaten the status of the dollar]-according to a recent report by Bloomberg News, analysts from Moody's Investor Service, an international rating agency, predict that although the global monetary system will remain dominated by the dollar in the coming decades, it will become more multipolar. The report points out that the shift towards protectionism and the risk of debt default in the United States will threaten the global dominance of the dollar. Even if the US debt ceiling is resolved, the domestic political environment has become more polarised over the past decade, undermining the predictability and effectiveness of US decision-making. In addition, the abuse of sanctions by the United States has further suppressed the free flow of US dollars in global trade and finance, which will further promote the diversified development of the global monetary system.
