Simon Johnson thinks that the recently passed Dodd-Frank Financial Reform Bill is not unlike the Sherman Antitrust Act of 1890. It includes a provision where federal regulators have "the right and the responsibility to limit the scope of big banks and, as necessary, break them up when they pose a 'grave risk' to financial stability." Johnson thinks that if just one regulator uses these extraordinary powers to break up too-big-to-fail banks just once, it will send a powerful message.
