Amar Bhide says it is time for banks to go back to their basic functions of taking deposits and making traditional loans, and to restrict risk taking activites, so that the U.S. can return to stable sustainable growth without recurring financial crises. He suggests a simple rule- activities that the average examiner cannot understand should not be allowed, which would restrict many of the activities of banks that lack transparency and pose systemic risks. He says the Dodd-Frank reforms have not tackled the dangers of risk-taking by banks and new leadership is required.
