Australian equities surrendered most of their early gains on Tuesday, as optimism around a potential de-escalation in Middle East tensions faded and investors reassessed persistent geopolitical risks.
The S&P/ASX 200 Index ended the session just 13.5 points, or 0.2% higher at 8,379.4, with four of the index’s 11 sectors finishing in positive territory.
Markets had initially rallied sharply at the open after United States President Donald Trump said he would postpone military strikes on Iranian energy infrastructure for five days following what he described as productive talks with Tehran aimed at ending hostilities.
However, the Iranian government denied that any discussions had taken place, dampening investor confidence and prompting a pullback from intraday highs.

Energy stocks delivered a mixed performance, with the sector finishing lower overall. Ampol and Beach Energy rose 1.2% and 1.9%, respectively, while Santos shed 2.6% and Woodside Energy eased 0.2%.
Financial stocks were also mixed. Commonwealth Bank dipped 1.8%, National Australia Bank shed 4.5%, and Westpac lost 1.6%, while ANZ ticked 0.5% higher after an upgrade from JPMorgan to “overweight”.
