Australia's Westpac Banking Corp unveiled a surprise 15 billion (€9.14 billion) Australian dollar plan to buy smaller rival St George Bank, in a deal that would create the country's biggest bank by market value.
The proposal by Westpac's new chief executive Gail Kelly, who joined the bank less than four months ago after heading up St George for nearly six years, was likely to ignite a wave of consolidation in the country's financial sector.
Westpac said the combined bank would have greater access to funding and generate savings at a time when funding costs have soared because of the global credit crunch.
The deal would skirt restrictions preventing mergers between Australia's four biggest banks - since Westpac is fourth and St George is the fifth largest - but it could provoke large rivals to investigate takeovers of smaller regional banks.
Australian banks have mostly dodged the subprime woes afflicting global banks, but the credit crunch has ramped up their funding costs and their customers are feeling the pinch of higher interest rates.
Westpac and St George put their shares in a trading halt today as they announced they were in confidential merger talks.
Westpac did not reveal a price for the offer, but Citibank analyst Craig Williams said in a note to clients that Westpac could pitch its offer at the equivalent of A$32.50, a premium of 22 per cent to St George's closing share price on Friday.
Trading in the shares of both companies was halted today.
The speculation of industry-wide consolidation sent shares in the sector surging, with potential regional targets Bendigo and Adelaide Bank Ltd up 7.4 per cent and Bank of Queensland up 5.8 per cent.
Westpac said in a statement the all-share deal would lower risks and costs for St George, which has a lower credit rating than its bigger rivals.
