Why do rising oil prices affect the RBA’s decision?

Higher oil lifts petrol and freight costs, which flows into headline inflation and can spill into services. If that keeps inflation above target for longer, the RBA may lean to tighter policy. Persistent fuel-driven pressure can also raise inflation expectations, making it harder to ease interest rates later.

How could a second RBA rate hike affect Australian mortgage rates?

If lenders pass through the change, variable mortgage rates would rise, lifting minimum repayments and lowering borrowing power. Fixed-rate borrowers remain insulated until their terms expire. The impact varies by lender and product, but a higher cash rate usually tightens credit conditions across new and existing home loans.

Which ASX sectors tend to react most to a higher-rate outlook?

Banks can benefit early from wider margins, though funding costs and competition matter. Utilities and staples often hold up as defensives. Rate-sensitive areas like tech, small caps, and property can underperform if bond yields rise. Miners may face cost pressure from diesel and a stronger dollar, even when commodities support revenue.

What should investors watch in today’s RBA statement?

Focus on language around services inflation, wages momentum, household demand, and any reference to energy costs. Guidance on the policy path matters as much as the headline move. A softer tone could ease bond yields and support growth stocks, while a firmer tone would likely lift yields and favour defensives.
