The Australian dollar skidded to a fresh three-month trough on Wednesday after a softer reading on core inflation snuffed out speculation interest rates would have to rise again and boosted the bond market.
Data showed the headline consumer price index rose at an annual 3.8% in the second quarter, matching market forecasts. Crucially the key core reading slowed to a two-year low of 3.9%, when analysts had looked for a steady 4.0%.
Data on retail sales were more mixed but a drop in quarterly volumes showed consumption remained subdued overall.
Investors had feared much higher inflation numbers and quickly reined back the probability of a rate hike at the Reserve Bank of Australia's (RBA) policy meeting on Aug. 6.
"The upshot is that although underlying price pressures are running uncomfortably high, we suspect that the RBA will take some comfort from the fact that demand and supply are moving closer into balance," said Abhijit Surya, an economist at Capital Economics.
"Accordingly, we're sticking to our view that the Bank is done tightening policy."

More volatility is likely after the Bank of Japan policy meeting later in the session as markets speculated the central bank could raise rates by as much as 15 basis points, and cut the amount of government bonds it buys.
The Aussie has already slid 9% to 99.65 yen AUDJPY=R in the past three weeks as speculation built about a BOJ tightening.
The U.S. Federal Reserve is also due to meet and investors are wagering heavily it will lay the groundwork for a policy easing as soon as September.
