The Australian dollar declined against the greenback on Tuesday, October 1, 2026, as the Reserve Bank of Australia raised its cash rate by a quarter-point to 4.6%. While the move marked a 15-year high for the central bank’s benchmark rate, it failed to surpass market expectations or provide long-term support for the currency as global foreign exchange markets contended with broader US dollar strength.
The Reserve Bank of Australia implemented its rate hike on Tuesday, moving the cash rate to 4.6%—its highest level in 15 years. According to official reporting, the decision was driven by escalating conflict in the Middle East and persistently high energy prices that continue to fuel domestic inflation pressures. However, the move caught no one by surprise. The adjustment was “largely anticipated” by financial markets, according to Samara Hammoud, an analyst at CBA, who noted that the tone of the central bank’s policy statement “was not hawkish enough to reinforce aggressive pricing for further rate hikes or sustainably support the Australian dollar.”
Foreign Exchange Markets React to US Dollar Vigor
By 10:10 GMT (12:10 Paris time) on Tuesday, the Australian currency had slipped 0.44% to trade at 1.4312 Australian dollars per US dollar. At the same time, the US dollar gained 0.30% against the European single currency, reaching 1.1338 dollars per euro. Ipek Ozkardeskaya, an analyst of Swissquote, pointed out that “the broad-based strength of the US dollar remains the primary market driver against major currencies.” Investors have steadily built up expectations for further monetary tightening from the US Federal Reserve, diminishing the comparative yield appeal of other central banks’ rates.
Upcoming US Economic Data and Geopolitical Risks
Currency traders are also weighing unfolding geopolitical tensions alongside heavy incoming macroeconomic data from the United States. State media reported that Iran anticipates receiving an official US response on Tuesday regarding conditions set for reopening the Strait of Hormuz, though outcomes remain highly uncertain following talks mediated by Qatar on the sidelines of the United Nations General Assembly.

On the domestic economic calendar in the US, Federal Reserve officials including governors Michael Barr, Christopher Waller, and the Fed's vice-president in charge of bank regulation, Michelle Bowman, are scheduled to speak on Tuesday, alongside the release of a consumer confidence indicator for September. Meanwhile, gold prices recovered slightly by 0.81% to trade at $4,149.36 per ounce, regaining a small fraction of the previous session's steep losses.
