The RBA's Anti-Inflation Armor

The Big Four banks are in for a more difficult 18 months than they've seen for a little while. The pressure on their margins is building, and then you've got the potential that their bad and doubtful debts will tick up. It's sort of ACD stuff. Is it just me or they turned out the music in this place, honestly? I'm not quite sure why the RBA is not selling from its large holdings of Australian government bonds. They're probably making capital losses along the way.
