The factors triggering the interest rate cut by the Reserve Bank of Australia may come earlier than anticipated. Ben Jarman, an economist at national australia bank limited sponsored adr, stated that, based on a range of indicators, Australia's inflation rate has returned to a level consistent with the central bank's target. However, he also mentioned that the Reserve Bank of Australia needs to be assured that this is sustainable and has used the adjusted trimmed mean inflation rate as the best way to exclude any noise. This adjusted trimmed mean inflation rate is already approaching the target level, and he believes that calculated on a seasonally adjusted annualized six-month basis, the next published data will be within the range of 2%-3%. Jarman stated that this should convince the Reserve Bank of Australia that the inflation target has been reached.
