The US Dollar Index (DXY) climbed above 98.00, trading around 98.10 during Asian hours on Tuesday, marking its second consecutive day of gains as geopolitical risks in the Middle East intensified and investors sought safe-haven assets [1]. The Greenback's strength was mirrored across major currency pairs, with GBP/USD dropping to near 1.3590 [2], USD/CAD rising to around 1.3690 [3], and NZD/USD slipping below mid-0.5900s [5]. The US Dollar was the strongest against the Australian Dollar, up 0.32%, and also posted gains against GBP (+0.20%), EUR (+0.20%), JPY (+0.22%), CAD (+0.11%), NZD (+0.23%), and CHF (+0.22%) [5].
The surge in the US Dollar was driven by mounting concerns over deteriorating US-Iran peace prospects. According to CNN, US President Donald Trump has grown increasingly frustrated with Iran's handling of negotiations to end regional hostilities, with aides suggesting a more serious consideration of resuming major combat operations than in previous weeks [1][2][3][4][5]. Iranian Parliament speaker Mohammad Bagher Ghalibaf warned that Iran’s military remains fully prepared to retaliate against any future strikes, further straining the fragile ceasefire [1][2][3][4]. Trump rejected Iran's latest peace proposal as "totally unacceptable" over the weekend [2][4][5]. Fears of a prolonged closure of the Strait of Hormuz, a critical shipping route, have heightened concerns about global energy supply disruptions [4][5].
WTI crude oil prices edged higher, trading around $95.70, as traders reacted to the possibility of supply disruptions and awaited the American Petroleum Institute (API) report due later Tuesday [4]. The spike in oil prices provided a partial safety net for the Canadian Dollar, given Canada’s status as the largest crude exporter to the US, but also reignited inflation concerns, with March’s annual inflation rate hitting 2.4% in Canada [3]. The Bank of Canada recently held rates steady, but a prolonged conflict could force a reassessment of its neutral stance [3].
Market participants are closely watching the US Consumer Price Index (CPI) inflation report for April, expected later Tuesday. Consensus forecasts project headline CPI to rise 3.7% YoY (up from 3.3% in March) and core CPI to increase 2.7% YoY (up from 2.6%) [2]. A hotter-than-expected reading could further bolster the US Dollar and support the narrative of the Federal Reserve keeping rates higher for longer [2][5]. Meanwhile, expectations that the Reserve Bank of New Zealand (RBNZ) may maintain a cautious stance or consider tightening to bring inflation back to the 2% midpoint could offer some support to the NZD/USD pair and limit losses [5].
Political developments in the UK added localized pressure on the British Pound, as Prime Minister Keir Starmer faced calls to set a departure date following massive losses for the Labour Party in recent elections. Rising UK gilt yields and political uncertainty weighed on GBP/USD [2].
Looking ahead, President Trump’s upcoming meeting with Chinese President Xi Jinping later this week is expected to focus on trade, artificial intelligence, and global energy security, with potential implications for global markets [1][4].
CONCLUSION
Escalating US-Iran tensions have triggered a broad flight to safety, propelling the US Dollar higher against major currencies and lifting WTI crude prices amid supply disruption fears. The market is bracing for further volatility as investors await key US inflation data and monitor geopolitical developments. The outcome of upcoming US-China talks and the CPI report will be pivotal in shaping near-term market direction.
