Hedge funds are increasing their bullish bets on the Australian dollar against the New Zealand dollar, anticipating that the Reserve Bank of Australia (RBA) will raise interest rates while political risks weigh on the kiwi. This sentiment is driven by recent Australian inflation data for July 2026, which surprised markets with stronger-than-expected figures across both headline (1.0% monthly, 3.5% annual) and core measures (0.5% monthly trimmed mean, 3.6% annual). This data has significantly increased the probability of a 25 basis point rate hike by the RBA at its September meeting, moving market expectations away from a potential pause in tightening.
Conversely, the New Zealand dollar faces headwinds. The Reserve Bank of New Zealand (RBNZ) recently provided hawkish guidance, which initially sparked a short squeeze against the Australian dollar. However, analysts at Goldman Sachs and Barclays suggest that interest rate differentials between the two economies may have peaked. Additionally, hedge funds have begun to temper their expectations for aggressive RBNZ rate hikes, with some betting that a weakening economic backdrop in New Zealand will force the central bank to undershoot the five quarter-point rate increases currently priced into swaps markets. This indicates a potential divergence in monetary policy paths between the two central banks.
Bank of America analysts also favor shorting the AUD/NZD pair, citing an expected widening policy gap where the RBNZ is seen maintaining a more restrictive stance compared to the RBA. They emphasize that if the RBA signals policy easing or a pause, while the RBNZ remains anchored by inflation concerns, the interest rate differential would narrow or reverse, creating a strong fundamental case for the trade. The AUD/NZD cross is also sensitive to real yield differentials and short-term yield spreads between Australian and New Zealand government bonds.
Political factors in New Zealand, such as upcoming elections, are also contributing to the bearish outlook for the kiwi. This uncertainty, combined with a potentially more hawkish RBA and slower RBNZ tightening, creates a compelling scenario for hedge funds to favor the Australian dollar. The current market positioning reflects a rapid reassessment of interest rate differentials, with the Australian dollar strengthening significantly after the inflation data, breaking through key technical levels against the US dollar and likely against the kiwi as well.
