New Zealand Dollar declines as US Dollar rebounds on safe-haven demand

NZD/USD extends its losses for the second successive day, trading around 0.5880 during the European hours on Tuesday. The pair depreciates as the US Dollar (USD) gains on increased safe-haven demand amid heightened geopolitical tensions.

Iran ruled out any future negotiations with United States (US) President Donald Trump, according to Iranian outlets and a X post by an adviser to Parliament Speaker Mohammad Bagher Ghalibaf. Headlines note that Tehran will wait until the US President’s term ends on January 20, 2029, to resume talks. "Trump will not reach an agreement with us. We will accompany him until his term ends," Majid Shakeri, adviser to Ghalibaf, said

This geopolitical tension has driven a sharp rally in crude oil, which in turn has pushed US Treasury yields higher. Concerns are growing that the Federal Reserve (Fed) may feel compelled to raise rates sooner rather than later, even against the backdrop of a cooling labor market. Investors are now closely watching upcoming inflation data this week to gauge the Fed's next move, with the CME FedWatch Tool showing that market-implied odds of a 25-basis-point Fed rate hike in September have climbed nearly 52%, up from 44.4% just a day prior.

Higher oil and rate hike bets weigh on global sovereign bonds

Analysts at Deutsche Bank highlight that the combination of rising energy prices and renewed policy tightening concerns left fixed income markets under pressure, noting that “that backdrop of higher oil prices and rate hike speculation meant it was a tricky session for sovereign bonds around the world.”

Cleveland Fed President Beth Hammack emphasized that the central bank will likely need to execute multiple rate hikes to get broad-based inflation under control. Speaking with Yahoo Finance, Hammack, who notably dissented at the July meeting in favor of an immediate hike, argued that current policy remains insufficiently restrictive. She highlighted the upcoming Consumer Price Index report as a pivotal test that will dictate the Fed's trajectory moving forward.

Rising oil prices have sparked fresh debate on how the Reserve Bank of New Zealand (RBNZ) might approach its September policy meeting. Markets are exercising caution ahead of New Zealand’s third-quarter inflation expectation figures, particularly after the Q2 data showed an unexpected acceleration.

New Zealand Prime Minister Christopher Luxon has called an urgent, in-person caucus meeting for Wednesday morning to confront growing speculation surrounding his leadership. Following a turbulent week marked by reports of MPs receiving calls about a potential leadership challenge, Luxon is acting decisively to suppress internal dissent before it metastasizes into a campaign-defining issue for the National Party.
