• NZD/USD weakens amid a tense geopolitical backdrop in the Middle East.
• The US Dollar remains supported by expectations of a restrictive monetary policy stance.
• New Zealand’s central bank adopts a cautious tone in response to supply shocks.

NZD/USD trades around 0.5868 on Monday at the time of writing, down 0.52% on the day. The pair remains under pressure amid an environment marked by heightened geopolitical uncertainty, which typically supports safe-haven assets and the US Dollar (USD).

Tensions between the United States (US) and Iran continue to fuel risk aversion. Tehran warns it will respond forcefully to any US intervention in the Strait of Hormuz, a strategic chokepoint for global Oil transport. Recent incidents, including drone attacks and reported missile strikes, according to some sources, have intensified fears of military escalation, although Washington denies any direct hit on its vessels. In this context, potential disruptions to energy supply are keeping Oil prices elevated, reinforcing global inflation risks.

This dynamic is also supporting US Treasury yields and strengthening the US Dollar, driven by expectations of a tighter monetary policy stance. Markets are increasingly pricing in the possibility that the Federal Reserve (Fed) will keep interest rates higher for longer, or even raise them further if inflationary pressures persist. According to the CME FedWatch tool, the chance of a rate hike early next year has risen notably in recent days.

On the New Zealand side, the Reserve Bank of New Zealand (RBNZ) maintains a cautious stance. Monetary Policy Committee member Prasanna Gai emphasizes that supply shocks linked to the Strait of Hormuz do not automatically justify monetary tightening. He favors a conventional “look-through” approach to temporary disruptions, noting that the conditions required for pre-emptive tightening are not currently in place. This accommodative stance contrasts with that of other central banks and weighs on the New Zealand Dollar (NZD).

Analysts at BNY echo this view, highlighting that the RBNZ remains mindful of the fragility of the domestic economy following a series of aggressive rate cuts in 2025. While the neutral rate is seen as higher, the priority remains supporting economic activity rather than responding immediately to inflationary pressures deemed temporary.

Overall, the combination of a resilient US Dollar and a cautious New Zealand central bank continues to exert downward pressure on NZD/USD.
