Australian ASX 200 swings from record high to decline amid Rio Tinto earnings and oil price surge

ASX 200 Rio Tinto CSL Group oil price Brent crude

On July 29, 2026 the S&P/ASX 200 index climbed to 9,028 points, its highest level since early March, driven by a 5.3% surge in Rio Tinto shares after the miner posted its strongest half‑year earnings in four years and announced its biggest interim dividend since 2022. Biotechnology firm CSL Group also jumped 7.7% after unveiling trials of a new process to increase immunoglobulin production, lifting healthcare stocks to their highest level since July 10. Traders priced an about 80% chance that the Reserve Bank of Australia would hold rates steady at its August meeting.

The rally was short‑lived. The following day the benchmark fell to 9,006.7 points, down 0.35%, as Middle‑East tensions pushed Brent crude up roughly 9% to around US$87.50 a barrel. Higher oil prices boosted energy stocks, with Ampol up 1.7% after forecasting a 150% earnings lift for the first half of the year. Rio Tinto continued to rise on its earnings backdrop, while fellow miners BHP Group and Fortescue lost ground amid volatile iron‑ore futures.
