The Australian dollar hit three-month highs against the US currency on Monday, boosted by expectations the central bank will raise domestic interest rates this week to curb strong inflation pressures. The Aussie had moved up to $0.9046/50, from $0.8952/54 late on Friday.
It had risen to $0.9053, the highest since November 14, extending its rebound from a five-month low struck on January 22 when a wave of risk aversion saw investors dump the currency.
