CAMBRIDGE – America’s long-controversial Glass-Steagall Act of 1933, which separated deposit-taking commercial banks from securities-trading investment banks in the United States, is back in the news. This separation long symbolized America’s unusual history of bank regulation – probably the most unusual in the developed world.&nbsp;
纽约—长期饱受争议的1933年格拉斯-斯蒂格尔（Glass-Steagall）法案——规定吸纳储蓄的商业银行与交易证券的投资银行必须分业经营——再一次进入了新闻中心。分业经营曾经是美国不同寻常的银行监管史（大概是发达世界中最不同寻常的一段监管史）的象征。
