The finalisation yesterday of a financial lifeline by the banking syndicate to Babcock & Brown clarifies that, for now at least, foreign banks aiming to blackmail the major Australian banks into taking over small slices of debt will fail.But not only are foreign banks in line, metaphorically speaking, with every other lender to the list of distressed customers (of which the Centro group is the other prominent member).There are also suggestions that foreign banks, with the Australian banks playing a supporting role, aim to be in line, almost literally, with every other supplicant at the door of the Australian Treasury seeking funding and additional credit guarantees.Another issue on the crowded agenda of banks and the Treasury may be the aggregate level of syndicated loans funded by foreign banks and due to roll over in the course of the next six, 12 or 24 months.Whatever this refinancing hurdle is, a number of foreign banks, and with the major Australian banks in support, are in the early stages of canvassing the merit of a Treasury backstop to this refinancing requirement.So even though the foreign banks and domestic banks all enjoy a government guarantee on their liabilities of one form or another there is a still a worry that foreign banks, or other banks, won't roll their loans.The banks' customers may have to deal with this prospect in other ways, including by raising new equity (as the sounder, listed companies are already doing) or by selling assets.And any bank proposals for more Treasury aid are in a lengthening queue (with vehicle financiers and state governments also in line).
