Key Takeaways

1.The RBA hiked the cash rate by 25bps to 4.6%—the highest level in 15 years—due to domestic capacity constraints, Middle East tensions, and the AI boom.
2.Global equities closed lower as rising bond yields dampened risk appetite, with the US 30-year Treasury yield hitting its highest level since 2002.
3.CBA forecasts Australian headline CPI to accelerate to 4.0%/yr in August with trimmed mean steady at 3.6%/yr; a 1.0%/qtr Q3 outcome could prompt another RBA hike in November.
