Australian Dollar Dips as RBNZ Rate Hike Looms

The Australian Dollar (AUD) has weakened against the New Zealand Dollar (NZD) as investor confidence wanes. The Reserve Bank of Australia (RBA) raised its cash rate to 4.60% in 2026, the highest since 2011, while the Reserve Bank of New Zealand (RBNZ) sits at 2.75%. This gap pushed the AUD/NZD exchange rate to nearly 1.2500 on September 22, its highest since early 2013, with the Kiwi losing about 3% to the Aussie between late August and late September.

Money markets fully expect an RBNZ rate hike by December, with the RBNZ set to decide on October 28, six days before the RBA meets on November 3. A single RBNZ hike could narrow the interest rate gap until the RBA's next meeting. Key economic data releases include the Australian Industry Group (AiG) index for August, out on Tuesday at 22:00 GMT, and October consumer inflation expectations on Thursday at 00:00 GMT. RBNZ Governor Breman will also speak on Thursday.

A reading above 4.9% in consumer inflation expectations could support another RBA hike on November 3, pushing AUD/NZD back toward 1.2450. A softer reading would leave the exchange rate reliant on RBNZ actions. Technical analysis shows resistance at 1.2450 and 1.2500, with support at 1.2400, 1.2350, and 1.2300. The daily Stochastic Relative Strength Index (Stoch RSI) suggests downward momentum.
