Australian dollar has risen a quarter of one US cent after the release of stronger-than-expected inflation data.

The Australian Bureau of Statistics (ABS) announced the headline consumer price index (CPI) rose 1.4 per cent in the September quarter, for an annual rate of 2.0 per cent.

The median market forecast was for headline CPI to rise by 1.1 per cent in the September quarter for an annual rate of 1.7 per cent, according to an AAP survey of 15 economists, conducted last week.

The Australian dollar was at $US1.0273 and by 11:31pm it had risen to $US1.0304.

The CPI figures are seen as crucial for the Reserve Bank of Australia’s (RBA) interest rate decision at the November board meeting: a cut in the cash rate is more likely if inflation is not too high.

澳洲上季核心消費者物價（CPI）漲幅高於經濟師預期，澳元聞訊攀升，投資人對央行將降息的信心也減少。

統計局今天表示，CPI截尾平均數較前1季上升0.7%，彭博訪調的26位經濟師預估中值為增加0.6%。CPI則較前1季攀升1.4%，分析師預測上揚1%。

在CPI報告出爐後，彭博彙整的數據顯示，交易員認為11月6日降息的機率從昨天的95%降至75%。在歐債危機對全球成長造成威脅及大陸經濟成長趨緩之下，澳洲儲備銀行總裁史蒂文斯（Glenn Stevens）5月、6月和10月祭出降息。

雪梨花旗集團（Citigroup Inc.）資深經濟師布瑞南（Paul Brennan）在報告發布前表示，通膨速度較預估強勁，「恐衝擊11月降息的預期」。
