The New Zealand dollar weakened for a second straight session on Friday, slipping below 0.5900 against the US dollar as geopolitical tension near the Strait of Hormuz underpinned demand for the safe-haven greenback.
The kiwi retreated from a weekly high near 0.5925, its strongest level since March 11, and was set to close the week with gains overall, despite the latest pullback.
Tension in strait of Hormuz offsets truce impact
A 10-day truce between Israel and Lebanon has eased some regional pressure, but a continuing US naval blockade of Iranian ports has kept markets on edge. The Strait of Hormuz, a critical chokepoint through which around 20% of global oil consumption passes, remains a key focus for energy and currency markets.
This backdrop has helped the US dollar recover from its weakest levels since late February, as traders shifted toward perceived safety.
Hopes for US–Iran talks temper anxiety
US President Donald Trump said on Thursday that Iran was “close” to a deal with Washington. Reports suggest both sides have agreed in principle to hold new talks, though no date or venue has been set.
Expectations that diplomacy could ease tensions have already led the Bloomberg Dollar Spot Index to give back much of its earlier conflict-driven gains. A firm agreement to de-escalate would likely reduce safe-haven demand for the dollar; a breakdown in discussions could quickly reverse that move.
Fed outlook caps dollar upside
While geopolitical risk is lifting the dollar, expectations for US monetary policy are limiting the scale of the move.
Rate futures currently imply roughly a 30% chance of a Federal Reserve rate cut by year-end, and CME-listed Fed funds futures suggest nearly a 70% probability that rates will stay unchanged through the end of 2026. This outlook curbs the appeal of the dollar by narrowing the expected yield advantage over other currencies.
Recent comments from New York Fed President John C. Williams point to a cautious economic view, with projected US growth of 2.0–2.5% this year amid uncertainty linked to the conflict. Such signals reinforce the case for a steady policy stance.
Global volatility eases but remains elevated
Market anxiety has eased from its peak. A two-week ceasefire that began on April 8 has helped push the CBOE Volatility Index (VIX) down to 19.5, close to its 20-year average, indicating that the initial shock from the conflict has been largely absorbed.
Even so, traders expect elevated swings to persist as developments in US–Iran relations and regional security continue to shape sentiment across currencies, equities, and commodities.
Dollar’s dominant role in currency markets
The US dollar remains the dominant force in global foreign-exchange trading, on one side of more than 88% of all transactions, with average daily turnover of about $6.6 trillion as of 2022.
Its value is primarily driven by Federal Reserve policy aimed at price stability and maximum employment, through interest rate decisions and, in rare situations, tools such as quantitative easing or quantitative tightening. This policy anchor often outlives short-lived geopolitical shocks in determining longer-term currency trends.
Classic push-and-pull on currency valuations
The current backdrop highlights a familiar tension in currency markets: the dollar’s role as a refuge in times of global stress versus the drag from expectations of a stable or lower interest rate path.
Naval activity around the Strait of Hormuz has amplified safe-haven flows into the dollar and away from higher-beta currencies like the New Zealand dollar. At the same time, the perception that the Fed is unlikely to tighten further makes lower-yielding currencies relatively less penalized, limiting how far the dollar can run.
Domestic backdrop for the New Zealand dollar
Local developments are also shaping the kiwi’s profile. New Zealand’s annual food inflation has eased to 3.4%, reducing pressure on the Reserve Bank of New Zealand to raise rates aggressively. A less hawkish stance can weigh on the currency by narrowing its yield appeal versus the US dollar.
That said, reduced domestic inflation risk also softens downside pressure, as it lowers fears of policy-induced economic slowdown.
Focus turns to central bank signals and Middle East headlines
Traders now look to upcoming remarks from Federal Open Market Committee members for clues on the timing and direction of US policy moves. Any shift in tone could quickly alter rate expectations and ripple through currency markets.
At the same time, the outcome of diplomatic efforts between Washington and Tehran remains a key driver. A durable de-escalation would likely erode some of the dollar’s safe-haven bid and could provide breathing room for the kiwi. Conversely, a renewed flare-up or a collapse in talks could revive volatility and push the New Zealand dollar lower again.
