BNY’s Bob Savage reports a widening gap between the New Zealand dollar (NZD) and Australian dollar (AUD), as markets prefer currencies linked to real assets. He says NZD has not gained flow support even with firm New Zealand soft commodity prices.
He links weaker NZD demand to energy and fuel costs affecting the balance of payments, and to lower nominal and real rates. He also points to concerns that the Reserve Bank of New Zealand (RBNZ) may not tighten enough if inflation risks rise.
Shift In Cross Border Positioning
He says these currencies usually move slowly in cross-border holdings, but the pattern changed after early February. He cites a shift from broad convergence to a 40pp spread, based on current holdings as a share of their rolling 12-month averages.
Savage says AUD is supported by improved terms of trade and less hedging, while NZD has seen the opposite. He notes asset owners have reduced AUD hedges while adding NZD equivalents.
He says large AUD/NZD moves could affect New Zealand’s trade-weighted indices and the outlook for tradables inflation. He adds that if the divergence feeds into spot moves, the RBNZ may need to respond through interest rates.
We are seeing a significant divergence in fund flows between the Australian and New Zealand dollars, creating a clear opportunity. Markets are strongly favoring currencies backed by hard assets, which benefits Australia. This suggests establishing long AUD positions against other currencies, particularly the NZD.
Trade Expression And Risk Framing
Australia’s economic footing appears much stronger, supported by its commodity exports. With iron ore prices recently pushing past $145/tonne, a high not seen since late 2025, the country’s terms of trade have improved by over 2% in the first quarter of 2026. This fundamental strength makes buying AUD futures or call options an attractive strategy.
Conversely, the New Zealand dollar is struggling despite its own healthy commodity prices. The nation’s current account deficit recently widened to 7.8% of GDP due to high energy import costs, and Q1 2026 GDP growth was a sluggish 0.2%. This economic weakness suggests traders should consider shorting the NZD, perhaps through put options to limit risk.
The most direct way to trade this divergence is by going long the AUD/NZD currency pair. The flow data, which showed a 40-percentage-point spread in holdings by February, indicates that large asset owners are already positioned this way by reducing AUD hedges. This trend provides a tailwind for long AUD/NZD spot or futures positions.
There is a risk that the Reserve Bank of New Zealand will be forced to respond to a weakening currency, which could cause a spike in volatility. New Zealand’s inflation remains stuck around 4.5%, but weak growth ties the RBNZ’s hands, a dynamic that began to emerge back in mid-2025. Traders could use options like straddles around RBNZ meeting dates to profit from any surprise policy move.
