Economists do little to promote bank competition

The royal commission into banking, whose public hearings start on Monday, won't get a lot of help from the Productivity Commission's report on competition within the sector. It's very limp-wristed.

The report's inability to deny the obvious - that competition in banking is weak, that the big four banks have considerable pricing power, abuse the trust of their customers and are excessively profitable – won it an enthusiastic reception from the media.

Trouble is, its distorted explanation of why competitive pressure is so weak and its unconvincing suggestions for fixing the problem. It offered one good (but oversold) proposal, one fatuous proposal (to abolish the four pillars policy because other laws make it "redundant") and a lot of fiddling round the edges.

It placed most of the blame for weak competition on the Australian Prudential Regulation Authority, egged on by the Reserve Bank, for its ham-fisted implementation of international rules requiring banks to hold more capital, and for its use of "macro-prudential" measures to slow the housing boom by capping the banks' ability to issue interest-only loans on investment properties.

The banks had passed the costs of both measures straight on to their customers. It amounted to an overemphasis on financial stability (ensuring we avoid a financial crisis like the Americans and Europeans suffered) at the expense of reduced competitive pressure on the banks.

This argument is exaggerated. Even so, it's quite likely that, in their zeal to minimise the risk of a crisis, APRA and the Reserve don't worry as much as they should about keeping banking as competitive as possible.

The report's proposal that an outfit such as the Australian Competition and Consumer Commission be made the bureaucratic champion of banking competition, to act as a countervailing force on the committee that makes decisions about prudential supervision, is a good one.

The report's second most important explanation for weak competition is inadequacies in the information banks are required to provide to their customers. Really? That simple, eh?

See what's weird about this? It's blaming the banks' bad behaviour on the regulators, not the banks. If only the bureaucrats hadn't overregulated the banks, competition would be much stronger.

Why would the bureaucrats in the Productivity Commission be blaming other bureaucrats for the banks' misdeeds? Because this is the prejudiced, pseudo-economic ideology that has blighted the thinking of Canberra's "economic rationalist" econocrats for decades.

Whatever the problem in whatever market, it can never be blamed on business, because businesses merely respond rationally (that is, greedily) to whatever incentives they face. If those incentives produce bad outcomes, this can only be because market incentives have been distorted by faulty government intervention.

Market behaviour is always above criticism; government intervention in markets is always sus.

When the report asserted that the big banks had used the cap on interest-only loans as an excuse for raising interest rates, and would pass the new bank tax straight on to customers, there was no hint of criticism of them for doing so. They were merely doing what you'd expect.

In shifting the blame for these failures onto politicians and bureaucrats, the report fails to admit that the distortion that makes interest-only loans a worry in the first place is Australia's unusual tolerance of negative gearing and our excessive capital gains tax discount.

In criticising the bank tax, the report brushes aside the case for taxpayers' recouping from the banks the benefit the banks gain from their implicit government guarantee, and the case for taxing the big banks' super-normal profits (economic rent), doing so in a way that stops the impost being shunted from shareholders to customers.

Here we see a hint that the rationalists' private-good/public-bad prejudgement​ is only a step away from Treasury being "captured" by the bankers it's supposed to be regulating in the public's interest, in just the way it (rightly) accuses other departments of being captured.

The report's criticism of existing interventions would be music to the bankers' ears. Its fiddling-round-the-edges proposals for increasing competitive pressure have one thing in common: minimum annoyance to the bankers.

The Productivity Commission's rationalists can't admit that the fundamental reason for weak competition in banking comes from the market itself: as with many industries, the presence of huge economies of scale naturally (and sensibly) leads to markets dominated by a few big firms.

Market power and a studied ability to avoid price competition come with the territory of oligopoly. Have the rationalists spent much time thinking about sophisticated interventions to encourage price competition in oligopolies? Nope.

Have they learnt anything from 30 years of behavioural economics? Nope. When you've learnt the 101 textbook off by heart, what more do you need?
