For example, just two financial centers, London and New York, dominate international finance, and only 22 players conduct 90% of all global foreign-exchange trading. Such concentration is very efficient, but it also contributes to greater systemic risks, because, if the leading hubs fail, the whole system can collapse.
与其他供应链一样，在当今金融结构中，相互依存的网络集中汇聚于强大的中心。比如，两大金融中心——伦敦和纽约主导着国际金融，而22家主要机构控制着90%的全球外汇交易。如此集中具有相当高的效率，但也造成了更大的系统性风险，因为如果主要中心倒闭，整个体系都得崩溃。
