GFC effect on Mortgage Market Share
The “Big Four” Banks now hold 73.8% of outstanding mortgages in Australia, up from 56.8% two years ago in August 2007, for Australians the effective dawn of the Global Financial Crisis.
Had the two mergers approved in 2008 - the Westpac takeover of St George and the Commonwealth Bank takeover of Bankwest - not proceeded, the market share of the big four would currently stand at 62.9%.
“Australia’s major banks have shown remarkable stability over the last two years”, said Tony Crossley, head of mortgages and insurance at CoreData-brandmanagement.
“This stability is a significant factor in the mortgage lending growth of big four banks relative to their smaller competitors”.
Commonwealth Bank has a 25.3% of mortgage market share in Australia and Westpac 23.2%. This means that two banks hold almost half (48.5%) by value of all mortgages in Australia.
“The share of mortgages represented by ANZ and NAB has remained constant over this two year period at a little over 25%, although ANZ (12.5% up from 11.8% two years ago) are poised shortly to overtake NAB (12.8% down from 13.4% two years ago), which may be why NAB is now reacting through the purchase of Challenger, which is currently under ACCC consideration”, said Crossley.
Major findings
Big four - pre and post mergers
• The big four banks now hold 73.8% of mortgage market share in Australia, post the Westpac takeover of St George and the Commonwealth Bank takeover of Bankwest, August 2009
• If the ACCC did not approve the two mergers, then combined the big four banks market share would be 62.9%, August 2009
Big four no more
• In allowing the St George and Bankwest takeovers, the ACCC has handed power to two banks, the Commonwealth Bank and Westpac, which combined hold 48.5% of all outstanding mortgages by value in Australia
• In August 2007, as the GFC began, Commonwealth Bank and Westpac only controlled 31.6% of mortgages
NAB did not focus on mortgage growth
• National Australia Bank share of the Australian mortgage industry is shrinking, falling to 12.8% in August 2009 from 13.2% in August 2008 and 13.4% in August 2007
• The other three big banks all increased market share, either organically (ANZ) or takeover (CBA and WBC)
NAB decision to purchase the Challenger broker channel is an attempt to quickly build market share again, with the decision currently pending from the ACCC









Bill October 2, 2009
Government needs to regulate and put some more bite behind their words when you have the Big Four being this BIG! It puts the consumer and smaller lenders at risk of unfair practices.
But we know it won’t happen as the rich hold the power and the government is just a pawn in this Chess game.
Time to brush up on my game to try and keep up…
