What went wrong at the Fed? The chief executives of some of the largest banks in America are allowed to serve on its boards. During the Wall Street crisis of 2007, Jamie Dimon, the chief executive and chairman of JPMorgan Chase, served on the New York Fed’s board of directors while his bank received more than $390 billion in financial assistance from the Fed. Next year, four of the 12 presidents at the regional Federal Reserve Banks will be former executives from one firm: Goldman Sachs.

These are clear conflicts of interest, the kind that would not be allowed at other agencies. We would not tolerate the head of Exxon Mobil running the Environmental Protection Agency. We don’t allow the Federal Communications Commission to be dominated by Verizon executives. And we should not allow big bank executives to serve on the boards of the main agency in charge of regulating financial institutions.

If I were elected president, the foxes would no longer guard the henhouse. To ensure the safety and soundness of our banking system, we need to fundamentally restructure the Fed’s governance system to eliminate conflicts of interest. Board members should be nominated by the president and chosen by the Senate. Banking industry executives must no longer be allowed to serve on the Fed’s boards and to handpick its members and staff. Board positions should instead include representatives from all walks of life — including labor, consumers, homeowners, urban residents, farmers and small businesses.

The Fed must also make sure that financial institutions are investing in the productive economy by providing affordable loans to small businesses and consumers that create good jobs. How? First, we should prohibit commercial banks from gambling with the bank deposits of the American people. Second, the Fed must stop providing incentives for banks to keep money out of the economy. Since 2008, the Fed has been paying financial institutions interest on excess reserves parked at the central bank — reserves that have grown to an unprecedented $2.4 trillion. That is insane. Instead of paying banks interest on these reserves, the Fed should charge them a fee that would be used to provide direct loans to small businesses.

Third, as a condition of receiving financial assistance from the Fed, large banks must commit to increasing lending to creditworthy small businesses and consumers, reducing credit card interest rates and fees, and providing help to underwater and struggling homeowners.
