T o their critics central-bank digital currencies ( CBDC s) are a fad—a solution in search of a problem. To their supporters CBDC s are a necessary response to a digitising world. Central bankers everywhere are studying the idea. Recently several have signed up to an argument in their favour: that CBDC s will be needed to anchor the value of money in a cashless financial system. It is a notion that could prompt governments to rebuild their banking and payment systems. But does it withstand scrutiny?
他们的批评家中央银行数字货币（CBDC）是一种时尚，这是一个解决问题的解决方案。对他们的支持者，CBDC是对数字化世界的必要回应。各地的中央银行家都在研究这个想法。最近，一些人签署了一个有利的论点：将需要CBDC S以固定无现金金融体系中的货币价值为基础。这是一个可能促使政府重建其银行和支付系统的概念。但是它可以承受审查吗？
