AUD Soars as RBA Hikes Interest Rates

The Reserve Bank of Australia (RBA) interest rate decisions have a significant impact on the Australian dollar. When the RBA raises rates, it makes bank deposits and government bonds more attractive to overseas investors, which tends to push the AUD up. However, if other central banks like the US Federal Reserve are raising rates at the same time, the gap between them may not change much, and the AUD might not move significantly.

The RBA's cash rate is just one of several forces acting on the currency. Firm commodity prices, such as iron ore, and a softer US dollar can also contribute to the value of the AUD. In 2026, the AUD averaged near 64 US cents in 2025 but rose to over 72 US cents by May, its highest level in almost three years.

The size of the move depends on what markets expected, other central banks' actions, and global sentiment. Understanding this relationship makes RBA announcements easier to read for both mortgage holders and holiday planners.
