AUD/USD Plunges 0.50% as Inflation Data Sparks Dovish Repricing
The Australian dollar experienced a decline of 0.50% against the US dollar on September 30, settling at $0.69487. This loss in value came as a result of a softer-than-expected monthly inflation reading, which led to a rapid unwinding of hawkish Reserve Bank of Australia policy expectations by institutional investors.
The RBA had delivered a widely anticipated 25-basis-point interest rate increase to 4.60% just a day earlier, but the market's focus quickly shifted to the August Consumer Price Index report. The headline monthly consumer price growth printed below market forecasts, while underlying trimmed mean inflation metrics stabilized.
The modest undershoot in inflation triggered a dovish repricing in Australian short-term interest rate swaps, driving front-end Australian government bond yields lower and eroding market bets for additional monetary tightening in the near term. The US dollar maintained its firm bid across G10 currencies, supported by sustained upward momentum in US Treasury yields and a cautious global risk backdrop.
