Australian shares are set to open higher as global stock markets climb and oil prices decline, driven by renewed expectations of a potential agreement between the United States and Iran. Multiple outlets report that trading sentiment improves as the prospect grows that a deal could allow tankers to resume delivering crude from the Persian Gulf to international customers. The fall in oil prices is described as a key factor accompanying the market rally, suggesting traders are pricing in the possibility of increased supply or reduced disruption to shipping routes. The articles link the positive move in equities to broader market gains overseas, rather than company-specific news. All three sources frame the development as “deal hopes,” indicating uncertainty around timing and terms. Overall, the coverage describes a risk-on shift in share markets paired with easing energy prices, reflecting expectations for improved conditions in regional oil supply and trade. The reports present the US-Iran negotiations as the central catalyst behind the day’s market movement.
