“NEARLY five years after the bankruptcy of Lehman Brothers touched off a global financial crisis, we are no safer. Huge, complex and opaque banks continue to take enormous risks that endanger the economy. From Washington to Berlin, banking lobbyists have blocked essential reforms at every turn. Their efforts at obfuscation and influence-buying are no surprise. What’s shameful is how easily our leaders have caved in, and how quickly the lessons of the crisis have been forgotten.

“We will never have a safe and healthy global financial system until banks are forced to rely much more on money from their owners and shareholders to finance their loans and investments. Forget all the jargon, and just focus on this simple rule.

“Mindful, perhaps, of the coming five-year anniversary, regulators have recently taken some actions along these lines. In June, a committee of global banking regulators based in Basel, Switzerland, proposed changes to how banks calculate their leverage ratios, a measure of how much borrowed money they can use to conduct their business.”
