BHP and National Australia Bank pull Australian shares lower

what happened

Australian shares finished Tuesday slightly lower, Reuters reported. The S&P/ASX 200 gave up 0.3% to close at 8,816.90 points, recovering part of an earlier 1.1% drop. National Australia Bank shares ended 1.8% lower after sliding nearly 4% earlier in the session. The country's largest business lender expects a pre-tax restructuring charge of about A$300 million in 2027 and plans to cut up to 2,500 jobs. The financial sector fell 0.5% as a result, and only Commonwealth Bank of Australia among the Big Four rose, by 0.1%.

BHP shares dropped as much as 2.6% intraday after the world's biggest copper producer reported a sharp fall in first-quarter output. Bad weather and a deadly incident forced short stoppages at its Escondida site in Chile. Rio Tinto lost 1%, while mining stocks as a group fell as much as 2.2%.

Attention now turns to Wednesday, when Reserve Bank of Australia Deputy Governor Andrew Hauser may be questioned about the possibility of a fifth rate increase this year. Westpac forecasts core inflation rising 0.9% this quarter and annual inflation reaching 3.5%, above the RBA's 3.3% projection. Even so, Westpac analysts expect the central bank to leave rates unchanged. Energy stocks fell 1.3%, while healthcare gained close to 0.9%.

why it matters

Two factors matter here: pressure on miners tied to copper supply, and the possibility that the RBA keeps policy tight, which supports banks but weighs on borrowing-heavy companies. New Zealand's S&P/NZX 50 index slipped 0.2% to 13,631.69 points.

Mining and copper: weaker output pressures BHP and Rio Tinto; Australian banks face drag from NAB restructuring costs.
