The currency gained for a third day as traders added to bets the Reserve Bank of Australia will increase its benchmark borrowing rate from a 12-year high of 7.25 percent as soon as next month. The local dollar was the second-best performer of the 16 most-active currencies as inflation exceeded the central bank's target and topped a forecast by Governor Glenn Stevens.
The Australian dollar rose to 95.17 U.S. cents, the highest since March 1984, before trading at 94.93 cents as of 4:47 p.m. in Sydney. It gained from 94.63 cents immediately before the report was released and 94.34 cents late in Asia yesterday. Its previous high was 94.98 cents touched on Feb. 29. The currency may climb to 95.20 cents today, Trinh said.
Australia's dollar also gained against Japan's currency, rising to 97.80 yen from 97.34 yen late yesterday. It reached 97.99 yen, matching its April 21 high, which was the strongest level since Feb. 29. The currency may advance to 98 yen today, Trinh forecast.
Consumer prices rose 1.3 percent from the fourth quarter, when they gained 0.9 percent, the Bureau of Statistics said in Sydney. The median estimate of economists surveyed by Bloomberg News was for a 1.1 percent advance. The 4.2 percent annual gain was the fastest since the second quarter of 2001.
The RBA raised borrowing costs a quarter-point in February and March to cool inflation and bring the annual consumer-price index to between its 2 percent to 3 percent target.
Australia's dollar dropped as low as 90.92 cents on April 4 after Stevens said Australia's headline consumer prices probably rose about 4 percent in the first quarter from a year earlier, which may be the ``peak.''
Australia's dollar gained for a seventh day versus the yen, the longest run since July 20, as the odds of an RBA rate increase after its next meeting on May 6 rose to 30 percent from 10 percent yesterday, according to a Credit Suisse Group index based on interest-rate swaps. A similar index showed traders have begun pricing in a rate increase in the next 12 months.
