Glenn Stevens, governor of the Reserve Bank of Australia, told a parliamentary committee on Friday that "I, personally, am not averse" to a charge for the deposit guarantee.Stevens was responding to a question from Liberal MP Scott Buchholz "that you put a value on it [the guarantee] and charge."Stevens and Buchholz touched on the issue in the context of efforts by the latter to inflate measures of the Australian Government's debt-to-GDP ratio.Phillip Lowe, deputy governor of the RBA, told the Economics Committee of the House of Representatives that around A$620 billion in deposits was subject to the fee-free guarantee under the Financial Claims Scheme. The cap on guaranteed deposits was cut to $250,000, from $1 million, from February this year. Stevens also speculated on the policy option where "you did not have any guarantee at all.""The truth is that, if the financial system got into incredibly big strife and large institutions were on the brink of failure, it is pretty unlikely that a government could stand by and allow that. Something is going to be done."In that sense, there is always the potential for some obligation to come on to taxpayers, I think. It is important to minimise the probability of that, and that is what a lot of the regulatory reform work around the world is about at the moment, but I doubt that you could ever make that go away. "So, even if you did not have an explicit guarantee, you cannot just assume that there would never be any possibility of the taxpayers being on the hook in a big enough crisis. I do not think you could really make that assumption," he said.
