But in a world with such huge infrastructure needs, the problem is not a surplus of savings or a deficiency of good investment opportunities. The problem is a financial system that has excelled at enabling market manipulation, speculation, and insider trading, but has failed at its core task: intermediating savings and investment on a global scale.
当还担任美联储主席的时候，本·伯南克（Ben Bernanke）错误地将这一问题定义为“全球储蓄过剩”。但在一个拥有如此巨大基础设施建设需求的世界上，真正的问题不在于储蓄过剩或是缺乏良好的投资机会，而是我们的金融体系极为擅长操纵市场，投机和内幕交易，却无法完成自身的核心任务：在全球层面上撮合储蓄和投资。这也是为什么亚投行可以为全球总需求产生一点微小但急需的推动。
