I have a proposal to strengthen the U.S. financial system by simplifying its structure and making its institutions more accountable for their mistakes. Put simply, my proposal would help prevent another 2008-style crisis by prohibiting banking organizations from conducting broker-dealer or other trading activities and by reforming money-market funds and the market for short-term collateralized loans (repurchase agreements, or repos). In other words, Glass-Steagall for today.
