On Monday, the US Dollar (USD) strengthened significantly against major currencies, including the Australian Dollar (AUD), New Zealand Dollar (NZD), and British Pound (GBP), as heightened geopolitical tensions and cautious central bank outlooks fueled risk aversion in global markets [1][2][3]. US President Donald Trump dominated headlines with warnings that the US could target Iran’s energy infrastructure if Iran does not agree to a ceasefire on Washington's terms, and further threatened escalation if the Strait of Hormuz is not reopened to commercial traffic [1][2][3]. These comments intensified concerns over global oil supply, driving oil prices higher for the fourth consecutive trading day and supporting demand for the USD, which is the primary currency for global crude transactions [2][3].
The AUD/USD pair traded with a bearish bias around 0.6850, with technical analysis showing persistent selling pressure and oversold conditions, as the pair remained below key moving averages and pressed into recent troughs [1]. Immediate resistance was noted at 0.6866, with support at 0.6852, 0.6848, and a stronger floor at 0.6834 [1]. Meanwhile, NZD/USD fell sharply to its lowest level since November, trading around 0.5715, down 0.60% on the day, as the US Dollar Index (DXY) hovered near ten-month highs at 100.54 [2]. GBP/USD also collapsed to a four-month low at 1.3184, down more than 0.50%, as oil prices surged and the UK economic outlook dimmed [3].
Central bank commentary reflected a cautious approach. The Reserve Bank of Australia (RBA) is expected to hold rates unchanged at its upcoming meeting, maintaining a hawkish outlook due to persistent inflation above target and risks tilted to the upside [1]. The Federal Reserve (Fed) also left rates unchanged, with Chair Jerome Powell stating that monetary policy is "in a good place to wait and see" and emphasizing a data-dependent approach [2][3]. Powell reiterated the Fed’s commitment to bringing inflation back to 2% and acknowledged that supply shocks, including those from geopolitical events, could complicate the outlook [2][3]. According to the CME FedWatch tool, markets now expect the Fed to keep rates unchanged through this year, reversing earlier expectations of further hikes [2]. However, [3] notes that traders have increased the chances for a rate cut by the Fed by the end of 2026, highlighting some discrepancy in forward-looking expectations.
In the UK, economists pointed to vulnerabilities due to dependence on imported natural gas and persistent inflation above the Bank of England's target, painting a gloomy outlook as downside risks rise [3]. Recent data showed British business activity at a six-month low, rising input costs, and declining retail sales [3]. Upcoming economic releases in New Zealand and China, as well as US consumer confidence and job data, are expected to provide further direction for markets [2][3].
CONCLUSION
The US Dollar's surge was driven by escalating Middle East tensions, rising oil prices, and cautious central bank stances, resulting in sharp declines for AUD/USD, NZD/USD, and GBP/USD. Persistent inflation and geopolitical risks have led markets to expect steady rates from the Fed and RBA, while the UK faces economic vulnerabilities. Investors will closely monitor upcoming economic data for further market direction.
