BNY’s Head of Markets Macro Strategy Bob Savage reports a growing split between the New Zealand Dollar (NZD) and Australian Dollar (AUD), with market flows favouring currencies linked to real assets. New Zealand commodity prices are strong, but NZD has seen little flow support.
He says energy and fuel costs may affect New Zealand’s balance of payments, while NZD lacks underlying nominal and real rates that tend to support inflows. He also points to concerns that the Reserve Bank of New Zealand (RBNZ) may not move enough on interest rates given inflation risk.
Policy Divergence Between Aud And Nzd
By contrast, recent flows have favoured AUD, supported by terms-of-trade gains and reduced currency hedging. Asset owners have reduced AUD hedges while adding NZD equivalents, based on differences in policy messaging.
Savage notes that these currencies typically shift slowly in cross-border holdings. He reports a move from broad convergence in early February to a 40pp spread, measured as holdings versus rolling 12-month averages.
He adds that AUD/NZD moves affect New Zealand’s trade-weighted indices and could change tradables inflation. If the divergence feeds into spot rates, the RBNZ may respond through interest rates.
We are seeing a clear divergence between the Australian and New Zealand dollars, as markets prefer currencies backed by hard assets. The AUD is gaining from its strong commodity export position, while the NZD is failing to attract similar interest despite healthy prices for its own goods. This trend has created a 40-percentage-point spread in our currency holdings since early February 2026.
Implications For Positioning And Inflation
This policy difference has been growing since late 2025, when the inflation pictures began to separate. The Reserve Bank of Australia is holding firm with its cash rate at 4.35% to combat persistent inflation, which was last reported at a stubborn 3.6% for the first quarter of 2026. In contrast, the Reserve Bank of New Zealand has sounded less aggressive as their own inflation has cooled more quickly to 3.1%.
The divergence is also fueled by Australia’s stronger trade position, as iron ore prices have climbed 8% this year to over $125 per tonne. We have seen asset owners react by reducing their hedges on the AUD, showing confidence in its strength. At the same time, traders are adding hedges on the NZD, expecting it to weaken further.
For derivative traders, this points toward positioning for a higher AUD/NZD exchange rate, which has already broken through the 1.0950 resistance level seen last year. One strategy could be buying AUD/NZD call options to gain from further upside while defining the maximum risk. This allows traders to benefit if the divergence continues as we expect.
A major move in the AUD/NZD rate could impact New Zealand’s inflation outlook through its trade-weighted index. This creates a risk that the RBNZ might have to respond with an unexpected rate hike to support its currency. Traders should therefore watch the RBNZ’s upcoming statements closely for any change in tone.
