ASX rises as investors await RBA interest rate decision

The Australian sharemarket advanced its gains on Tuesday, August 11, 2026, according to reporting by the Financial Review, even as investors braced themselves for a pivotal monetary policy decision from the central bank. The S&P/ASX 200 Index climbed during the morning session, building on a modest opening gain as market participants weighed domestic corporate earnings alongside shifting global economic conditions.

Across the wider business landscape, attention remained firmly fixed on Sydney, where the Reserve Bank monetary policy board met to determine the path forward for borrowing costs. Following multiple rate hikes earlier in the year, financial markets widely anticipated that the central bank would keep the cash rate steady, according to the Australian Broadcasting Corporation. At the same time, the monetary authority prepared to release its quarterly Statement on Monetary Policy, updating forecasts for inflation, economic growth, and the unemployment outlook.

Local equities shrugged off a weak lead from international markets. Overnight trading sessions saw Wall Street indices weighed down by surging crude oil prices, which climbed toward $US88 a barrel. Capital.com senior financial market analyst Kyle Rodda noted that the upward pressure on oil stemmed from a lack of progress on a diplomatic deal between Oman and Iran regarding the Strait of Hormuz, coupled with escalating hostile rhetoric between Washington and Tehran.

Energy counters pushed higher on the local bourse in response to the tightening commodity market. Santos shares advanced after shipping hundreds of thousands of barrels of crude from its Pikka phase 1 project in Alaska, while Woodside also recorded notable gains. Conversely, technology shares lagged behind after Life360 posted a steep drop following its earnings announcement, despite narrowly beating consensus forecasts.

Corporate earnings reports heavily influenced individual stock movements throughout the session. Industrial conglomerate SGH dropped after its full-year earnings before interest and tax missed expectations, offsetting strong profits from its Boral division. Meanwhile, mortgage insurer Helia added ground despite posting a significant decline in half-year net profit, as investors sought out its special dividend. Austal surged after trading resumed following a temporary halt, disclosing a multi-billion-dollar takeover offer from Hanwha Defence USA for its American operations.

Market analysts warned that local asset prices could experience heightened volatility depending on the central bank's messaging.

Financial markets continued to price in a line-ball probability of one additional move upward in borrowing costs before the conclusion of the year, keeping traders on edge as the afternoon schedule approached.
