Answer in brief
The Reserve Bank of Australia made a fourth rate increase this year, citing persistent inflation and new energy pressures while acknowledging slower activity.
The decision and its timing
The Reserve Bank of Australia raised its cash rate target by 25 basis points to 4.60% on 29 September 2026. The board said the vote was unanimous. Its statement describes this as a further tightening after three earlier increases in the year; Reuters reported that the four moves together amount to one percentage point. The announcement changes the policy target, not every household's loan contract at once. Lenders still set customer rates and reset dates under their own terms.
Why the board tightened again
The RBA said inflation remained too high and that several risks flagged in August were materialising. It pointed to higher global energy prices and domestic capacity pressure, with firms reporting rising costs or plans to raise prices. The bank also said recent growth and inflation had been stronger than expected at its previous meeting. Those are the board's assessments, rather than a claim that any single oil-price move mechanically determines Australian inflation.
The trade-off for households and businesses
The same statement noted easing consumer spending, falling housing prices in most capital cities and a noticeable decline in new housing loans. Higher policy rates can restrain demand through borrowing and saving decisions, but the impact varies with fixed-rate terms, debt levels and bank pricing. Governor Michele Bullock acknowledged the difficulty for mortgage holders and businesses with loans at her media conference. The board is choosing tighter conditions despite those costs because it judges persistent inflation to be the larger risk to its mandate.
What is known and what comes next
The RBA said it could raise the target further if needed, but it did not announce another increase or a fixed endpoint. Future decisions depend on incoming inflation, demand and labour-market evidence. For readers comparing the next data release with this decision, the important distinction is between an observed price reading and a forecast of where inflation will settle. As of the 30 September evidence cutoff, the verified news is the 4.60% target and the board's stated reasoning, not a guaranteed path for mortgage costs.
Questions and answers
What did the RBA decide in September 2026?
On 29 September, its monetary policy board unanimously raised the cash rate target by 25 basis points to 4.60%.
Does a 25-point increase automatically change every mortgage rate?
No. The cash rate is an overnight market target. Banks set their own lending and deposit rates and decide when any change reaches customers.
