In readiness for the upcoming federal election, The Greens yesterday unveiled a banking policy that echoes Labor's populist bent toward the sector.The party, which may continue to wield influence in Senate deliberations, yesterday said it "would use a Royal Commission to fully examine the problems associated with the 'vertically integrated' model." This would include "looking at 'breaking up the banks' to separate retail banking from financial advice and investment banking," a step not yet supported by the Labor Party, the principal flag carrier for a Royal Commission.The Greens have stuck with plans to "apply a tax deductible levy of 0.20 percentage points on the asset base" on "institutions worth greater than A$100 billion."They estimated "this measure would raise nearly $15 billion over the forward estimates."The policy document argues that "the rate of the levy is equal to the lower bound of the RBA's estimate of the value of an implicit government guarantee. It is also the value suggested by the IMF based on the average benefit of implicit guarantees throughout the G20."Micro measures include restraints on ATM fees, further limits on charges imposed by payday lenders, and handing ASIC the responsibility to foster bank account portability.
