The New Zealand dollar climbed 0.4% on Friday to reach $0.5778, marking a three-week high against the US dollar.
The kiwi's advance followed a 1% overnight jump, driven by growing market conviction that the Reserve Bank of New Zealand (RBNZ) has further policy tightening to deliver.
35%—marking its third consecutive increase to combat persistent inflation—markets appear to be pricing in a more limited path for future hikes in Sydney.
This repricing highlights a sharp divergence in regional monetary policy expectations, with traders increasingly betting on a more aggressive stance from Wellington compared to its southern neighbor.
The kiwi's outperformance stands in contrast to the Australian dollar, which has lagged in recent sessions.
While the Reserve Bank of Australia (RBA) recently raised its benchmark interest rate to 4.35%—marking its third consecutive increase to combat persistent inflation—markets appear to be pricing in a more limited path for future hikes in Sydney.
The RBA's move, which aligned with market expectations, failed to generate the same sustained currency momentum seen in New Zealand, where the potential for additional tightening remains a key driver of FX flows.
