Taiwan's Fubon Financial is weighing a bid for Australia and New Zealand Banking Group's 39 per cent stake worth US$612 million in Bank Pan Indonesia (Panin), two sources said. "This is real," one of the sources said. "Some banks have pitched to Fubon for a mandate." ANZ was inviting preliminary bids for its stake in Panin and there was a very short list of bidders, the source said. Officials at ANZ and Fubon declined to comment on the latter's interest, which was first reported by Bloomberg. Spanish lender Banco Bilbao Vizcaya Argentaria (BBVA) was also interested in Panin, Bloomberg said. Reuters reported last month that ANZ had hired Goldman Sachs for the sale, which is expected to attract bidders from China, Taiwan and Japan. Australian banks are scrambling to raise capital and sell assets after a domestic regulator ordered them to set aside more reserves against their oversized mortgage books. Previous talks between ANZ and Japan's Mizuho Financial over the Panin stake stalled, partly because Mizuho's request for Panin board seats was opposed by the Gunawan family, which controls 46.5 per cent of the Indonesian lender, sources said.
