The central bank aims to keep inflation in a 2 per cent to 3 per cent range on average, and the third-quarter consumer-price index report is due on October 26. Recent changes to CPI data by the statistics bureau showed underlying inflation figures were "lower than those previously published," the minutes said.
RBA staff estimated that underlying inflation over the year to the June quarter would have been 2.25 per cent to 2.5 per cent, rather than 2.5 per cent to 2.75 per cent.
The RBA noted the reweighting took account of changing spending patterns, including consumers switching their expenditure toward goods and services whose relative prices had fallen, such as computing equipment.
Another difference was the exclusion of the interest margin measure in the deposit-and-loan facilities category of CPI, "which had been a source of volatility in inflation outcomes over recent years," it said.
The Australian dollar pared gains immediately after the release of the minutes from $1.0202 before the announcement and $1.0157 yesterday in New York. It bought $1.0208 at 12.43pm in Sydney, up 0.5 per cent from late yesterday in New York.
The minutes showed officials viewed the pace of near-term economic growth as "unlikely to be as strong as earlier expected," reflecting global and local factors.
Traders bet there is a 76 per cent chance Stevens will reduce borrowing costs by 50 basis points by year end, up from 72 per cent before release of the minutes, interbank cash-rate futures showed. The RBA has relied on the Australian dollar's strength to temper gains in consumer prices. The local currency reached $1.1081 on July 27, the highest level since it was freely floated in 1983.
