AUDUSD climbs 0.73% as US dollar weakens on ceasefire hopes and soft GDP data

The Australian dollar (AUD) strengthened significantly against the US dollar (USD) on May 29, 2026, with the AUDUSD pair climbing 0.7262% to reach 0.71708. This notable rally was primarily fueled by a broad weakening of the US dollar, which depreciated amid growing hopes for a potential ceasefire agreement between the United States and Iran, alongside softer-than-expected US economic data.

US Dollar Weakens on Geopolitical Optimism

Optimism surrounding a potential ceasefire agreement between the United States and Iran played a crucial role in reducing demand for the safe-haven US dollar. Reports on May 29, 2026, indicated an extension of the truce and an easing of restrictions through the Strait of Hormuz. This de-escalation of geopolitical tensions led to a sharp decline in global oil prices, further diminishing the appeal of the US dollar as a safe haven asset.

Lloyd Chan, Senior Currency Analyst at MUFG Global Markets Research, noted on May 29, 2026, that "Geopolitical risk premia may continue to unwind in the near term." Echoing this sentiment, Massimiliano Castelli, Head of Strategy in the Global Sovereign Markets Team at UBS Asset Management, commented that "It might well be that once this crisis in Iran, in the Middle East, is behind us, we expect the U.S. dollar to remain weak."

Softer US Economic Data Adds Pressure

Further contributing to the US dollar's softness were a series of disappointing US economic indicators released on the same day. The second estimate for Q1 2026 US Gross Domestic Product (GDP) was revised downwards to 1.6% from an initial projection of 2.0%. Additionally, the April 2026 Personal Consumption Expenditures (PCE) Price Index, excluding food and energy, showed a softer-than-expected rise of 0.2%. This data suggested a more modest underlying economic momentum than previously anticipated, prompting a reversal in US bond yields that had initially supported the dollar.

Australian Dollar Finds Domestic Support

On the Australian side, the local currency found robust support from ongoing hawkish sentiment surrounding the Reserve Bank of Australia (RBA) and significant domestic investment. The RBA had previously raised its cash rate to 4.35% at its May 2026 meeting, with economists anticipating rates to remain elevated through 2027. This provided a yield advantage for the Australian dollar, making it more attractive to investors.

Adding to the AUD's strength, a research note from Westpac Banking Corp. on May 29, 2026, highlighted a substantial data-center boom in Australia. The investment pipeline for these projects is projected to exceed A$155 billion, signaling strong domestic economic activity and bolstering confidence in the Australian economy.
