According to former key architect of Walls Street's 2008 bailout, Neel Kashkari, US banks are still "too big too fail". In a recent speech in Washington, he called for the break-up of these institutions and imposing a tax leverage to reduce systematic risks. If what Kashkari says is true, how will policymakers be able to avoid a wide chain reaction if one or more institutions struggles in the near term? The Minneapolis Fed is working on a new proposal to handle the possible return of "too big too fail". With elections coming up this issue will for sure be on the table.
