Analysis: a Big Four criticism that won't worry the Big Four

David Walker
Yesterday's "What Price Stability" report from centre-left think tank Per Capita contains one claim the Big Four will like: they should be left in peace to set their rates. And it contains a second that they just won't care about: that the appropriate step for a government concerned by their profitability is to set up a new no-frills, online-only, government-owned bank for low-income Australians.

This is pretty much exactly the one banking reform the Government won't touch with a long pole. Not only would it require a heap of funds the Government doesn't have, but the Per Capita report makes a thin case that it would do anything to reduce the Big Four's fairly impressive margins.

Per Capita's case is founded on three market failures. Its proposed government bank would do remarkably little about any of them.

• The report says that most customers are reluctant to move banks, which is true. It then suggests many low-income Australians would, nevertheless, be eager to move to an online-only government-owned bank, as opposed to getting a cheap, no-frills account from their existing bank or from an internet-centric competitor like ING.

• Echoing the common argument, the report says government provides an implicit guarantee to the banks. The policy argument for providing at least some support to banks in a crisis is relatively straightforward: bank-runs are themselves a form of market failure. As Per Capita points out, global regulators have been increasingly seeking "resolution regimes" which let bank shareholders lose their dough and bank managers lose their jobs while minimising the knock-on effects. But Australia's prudential supervision system pretty much does this already. (Our system is arguably too protective of banks' creditors, but the report pays no attention to this.)

• Per Capita notes the concern over the trade-off between bank competition and bank stability. It doesn't explain how a government bank would help solve this dilemma. You might think the report would mention that our last big failed bank was government-owned - the State Bank of Victoria. You might think that, but you'd be wrong.

Even more peculiar is that the report suggests there is too much capital invested in the Australian banking system - and then argues the best policy would be for the Government to put in yet more capital.

The report's greatest irony, though, is that the Big Four might well be happy to lose their low-income customers to a government-owned bank. These customers are widely believed to be the least profitable.

Per Capita, then, may be proffering an initiative which would make the banks more profitable, not less.
