Sydney Up 2.6%
In a widely-expected move, the Australian central bank left its cash rate unchanged at 2.75 percent. The RBA maintained its easing bias and stated that the Australian dollar was still at high levels. In reaction, the currency lost nearly 1 percent to fall below the $0.92 handle against the greenback.
"Overall, it seems the RBA is very comfortable with the current policy setting. It feels the AUD will depreciate further over time, which would help foster a rebalancing of growth in the economy," said Stan Shamu, market strategist, IG.
