New Zealand Dollar Tumbles After Australia's Rate Hike

The New Zealand Dollar (NZD) has fallen to its lowest level since June after Australia's Reserve Bank raised interest rates for the fourth time in 2026. The RBA hiked its cash rate to 4.60%, a move that was seen as less aggressive than markets had expected, with RBA Governor Bullock signaling no further tightening.

The decision sent shockwaves through currency markets, causing the Australian Dollar to fall and the NZD/USD exchange rate to break below 0.5650 for the first time in its slide. The Kiwi has been under pressure since Australia's previous rate hike on September 22, when RBA Governor Bullock warned that higher crude oil prices could push near-term inflation above the RBA's assumptions.

The Reserve Bank of New Zealand (RBNZ) has kept its Official Cash Rate (OCR) at 2.75%, a full point below the low end of the Fed's range, and the odds of an October hike have since climbed to about 80% after Governor Breman's warning on September 22.

The RBNZ may sound firmer than it did in its previous statement, but with the hike already priced in, only the guidance can surprise anyone. New Zealand's week holds a permits count and a mood survey, which could impact the NZD/USD exchange rate.
