NZD/USD rose for a third day after dipping to 0.5700 in Asia and then climbing to a near two-week high on Wednesday after US-Iran ceasefire news. It held above 0.5800 and changed little after the Reserve Bank of New Zealand (RBNZ) decision.
The RBNZ kept the Official Cash Rate at 2.25% for a second meeting in a row, as expected, citing uncertainty around economic and inflation prospects linked to the Iran war. The decision had limited impact on the NZD, with attention turning to Governor Dr Anna Breman’s press conference.
Ceasefire Headlines Lift Risk Sentiment
US President Donald Trump said planned military strikes on Iran would be paused for two weeks if Tehran agrees to an immediate and safe opening of the Strait of Hormuz. Iran’s Foreign Minister Seyed Abbas Araghchi said Iran would stop defensive operations if attacks on the country end.
Araghchi also said safe passage through the waterway would be possible for two weeks, which led to a sharp fall in crude oil prices and reduced inflation concerns. This lowered expectations of a US Federal Reserve rate rise and weighed on the US dollar, supporting NZD/USD.
We recall from last year the brief risk-on rally in NZD/USD that followed the temporary US-Iran ceasefire in 2025. The market reaction pushed the pair towards the 0.5800 level, but the fundamental picture today is vastly different. The Reserve Bank of New Zealand’s Official Cash Rate is no longer 2.25%, but has been held at a restrictive 5.50% for over a year.
This high interest rate environment is a response to persistent domestic inflation, which, according to data from Stats NZ, was still running at an annualized 3.8% in the first quarter of 2026, well above the RBNZ’s target. Therefore, any strength in the kiwi is now more closely tied to this attractive yield differential rather than fleeting risk sentiment. This makes long NZD positions against lower-yielding currencies a fundamentally sounder play than it was in 2025.
Competing Central Bank Policy Keeps Pair Range Bound
Similarly, the situation for the US dollar has changed dramatically, as the Federal Reserve has also maintained its funds rate above 5% to manage its own inflation issues. This contrasts sharply with the conditions in 2025, when the ceasefire news tempered rate hike expectations. The high US interest rate provides a floor for the dollar, suggesting the NZD/USD pair is more likely to be range-bound by competing central bank policies.
The geopolitical landscape offers another key difference, as the temporary dip in oil prices we saw in 2025 is a distant memory. Ongoing tensions in the Middle East have kept Brent crude prices elevated, hovering around $90 a barrel through early 2026, which continues to fuel global inflationary concerns. This backdrop supports a cautious stance and reinforces central banks’ commitment to keeping rates higher for longer.
Given this, traders should consider using options to trade the volatility around key inflation data releases for both New Zealand and the United States. A straddle on the NZD/USD could be an effective way to profit from a significant move in either direction following a CPI announcement, without betting on the direction itself. The market is now driven by hard data, unlike the geopolitical headline reactions of 2025.
