Competitive dynamics in the banking sector

The Treasury presentation earlier in the week to the Senate inquiry on competition in the banking sector drew attention to a number of significant developments which have, collectively, altered the competitive dynamics of the retail banking sector in recent years.

There has been further consolidation in the Australian banking sector since the global financial crisis.

A consequence of these factors is that the four major banks have expanded their collective market share across a range of loan and deposit products.

This is illustrated in the home loan market (Chart 5). The share of total housing loan credit for the five largest banks — the four major banks (Commonwealth Bank, NAB, ANZ and Westpac) plus St George — has increased from around 60 per cent before the onset of the GFC in mid-2007 to around
73 per cent.
