"Legislation claiming to end too-big-to-fail and to address the root causes of the crisis has done just the opposite. Instead of reducing systemic risk, Dodd-Frank has actually encouraged the biggest banks to become larger and more concentrated," Mr. Shelby said during a speech at the conservative Heritage Foundation this week. "It has put in place a structure where Main Street banks and other financial companies that had nothing to do with the crisis are treated as if they caused it ... By comparison, the Financial Regulatory Improvement Act directs regulators to analyze the systemic risk posed by each bank above $50 billion and regulate it based on the bank's individual risk profile. More importantly, it incentivizes financial institutions to reduce risk by giving them a path to shed this designation.I believe that less systemic risk is a good thing. That does not mean, however, that we should have a system devoid of risk."
