智库报告周五表示，金砖国家+应推进联合跨境支付机制建设，以减少对美元的依赖，但共同货币将面临重大的经济和制度障碍。
BRICS+ countries should press ahead with a joint cross-border payments mechanism to reduce reliance on the US dollar, but a shared currency would face major economic and institutional obstacles, a think tank report said on Friday.
非营利政策平台“金砖+智库”发布的这份报告，敦促由巴西、俄罗斯、印度、中国和南非领导的扩大后的主要新兴经济体集团，承诺建立此类机制，并采取必要措施使其运行。
The paper, published by non-profit policy platform BRICS+ Thinking, urged the expanded grouping of major emerging economies led by Brazil, Russia, India, China and South Africa to commit to such a mechanism and take the steps needed to make it work.
作者格雷戈里·T·钦、丹尼·夸和吉姆·奥尼尔表示：“他们的央行必须拥抱这一目标，并确保所有技术要求到位，以使该机制能够运作。”奥尼尔是高盛前经济学家，曾创造“金砖国家”这一缩写。
"It is absolutely crucial that their central banks embrace this goal and make sure that all the technical requirements are put in place to allow this mechanism to function," said authors Gregory T. Chin, Danny Quah and Jim O'Neill, the former Goldman Sachs economist who coined the BRICS acronym.
跨境支付长期以来一直在金砖国家议程上，但成员国金融基础设施整合的努力进展有限。
Cross-border payments have long been on the BRICS agenda, though efforts to integrate members' financial infrastructure have made limited progress.
金砖国家领导人在印度举行的9月峰会后发表的宣言中表示，将继续致力于更快、更廉价的跨境支付，包括通过连接支付系统和增加本币使用。
In a declaration issued after their September summit in India, BRICS leaders said they would continue work on faster, cheaper cross-border payments, including by linking payment systems and increasing the use of local currencies.
与此同时，引入共同货币将要求集团内部进行“剧烈改革”，包括更大程度的央行独立性、共同货币当局以及更少的资本流动限制。
Introducing a shared currency, meanwhile, would require "dramatic reforms" across the group, including greater central bank independence, a common monetary authority and fewer restrictions on capital flows.
作者们表示：“金砖+货币的初步前景并不乐观”，并补充称，该货币必须在国内和国际上都能自由兑换，而在现行政策下这是一个难以满足的要求。
"The initial prognosis for the possibility of a BRICS+ currency is not hopeful," the authors said, adding that it would have to be freely convertible both domestically and internationally, a difficult requirement under current policies.
“光是这一点就令人望而生畏，但进一步的重大挑战还包括这些国家在地理上的分散，以及它们对将政策自主权委托给一个共同央行毫无热情。”美国总统唐纳德·特朗普批评了金砖国家货币的前景，并多次威胁称，如果成员国创建共同货币或支持美元的替代品，将对其征收100%关税。
"This is daunting enough but further significant challenges include how these countries are geographically dispersed and how they show no enthusiasm for delegating policy autonomy to a common central bank." The prospect of a BRICS currency has drawn criticism from US President Donald Trump, who has repeatedly threatened 100% tariffs on member states if they create a common currency or back an alternative to the US dollar.
金砖国家没有共同货币，包括俄罗斯和印度在内的成员国都淡化了这一前景。然而，自西方在俄罗斯2022年全面入侵乌克兰后实施制裁以来，全球减少对美元依赖的努力已加快步伐。
BRICS does not have a common currency, and members including Russia and India have played down the prospect. However, efforts to reduce reliance on the dollar have gathered pace globally since Western sanctions were imposed on Russia following its 2022 full-scale invasion of Ukraine.
