Australia left interest rates unchanged Tuesday after the local dollar recorded the biggest drop among major currencies last quarter, cushioning the impact of lower commodity prices and a weaker outlook in key trading partner China, Bloomberg reported. In a largely unchanged statement, Reserve Bank of Australia Governor Glenn Stevens and his board kept the cash rate at a record-low 2%, as predicted by markets and economists, following reductions in May and February. The currency dropped almost 9% in the June-September period. Australia has so far had little success in stimulating industries with rate cuts outside of real estate as a decade-long mining investment boom unwinds.
