ASX eases as RBA decision looms; NAB slides

ASX 200 – Australian shares slip on uncertainty around Iran and a looming RBA call, while NAB shares fall after weaker results.
Australian shares opened the week on a softer note as investors weighed lingering geopolitical uncertainty alongside a key upcoming Reserve Bank of Australia decision.
The S&P/ASX 200 edged down 0.2% to 8712.9, with five of 11 sectors in the green, led by technology. Still, attention remains fixed on Tuesday’s RBA interest rate outcome, where markets are looking for another hike.
This mix of global tension and local monetary policy expectations is shaping sentiment, even as parts of the market try to hold up.
Meanwhile, National Australia Bank fell sharply after its first-half cash earnings came in below expectations.. NAB’s results were weighed by an accounting-related hit tied to changes in software accounting. while the bank said cash earnings rose when excluding that impact.. Management also pointed to a more volatile economic backdrop influenced by geopolitical tensions, alongside higher provisions for bad debts.
Across the big banks, Commonwealth Bank dipped slightly, Westpac moved lower, and ANZ was modestly higher in early trade. The contrast underscores how company-specific fundamentals are still driving stock moves, even when the broader market tone is cautious.
What matters here is the message investors take from earnings: beyond the headline numbers, banks are signaling how they’re adapting to a tougher risk environment.
Outside the financials, oil prices were an important early driver after developments related to the Iran war kept traders alert. With Brent and US crude both easing in early trading, local energy stocks were pulled down, while gold stocks moved higher.
In markets closer to consumers and growth, technology stocks generally held up. Life360 jumped strongly, while Xero and Technology One also rose. Media also saw its own momentum, with Southern Cross Media moving higher following leadership change intentions.
By the close of the news cycle, the pattern is clear: when uncertainty clusters around geopolitics and rates, investors tend to reward resilience and punish surprises, which is why today’s lagging stocks and leading sectors may change quickly into the RBA decision.
