RBA Raises Cash Rate to 4.60% as Inflation Risks Build

The Reserve Bank of Australia raised its cash rate target by 25 basis points to 4.60% on Tuesday, resuming monetary tightening after keeping rates unchanged at its two previous meetings. The move is the fourth quarter-point increase of 2026 and takes the cash rate 100 basis points above the 3.60% level in place at the end of last year. The new target takes effect on September 30.

The Monetary Policy Board’s decision was unanimous. In its September policy statement, the RBA said some of the upside inflation risks it identified in August are now materialising. It pointed to higher global energy prices as the Middle East conflict has broadened, rapid price growth for technology-related goods linked to artificial-intelligence demand, and continuing pressure on the economy’s productive capacity.

The September increase follows rate rises in February, March and May, which took the cash rate from 3.60% to 4.35%. The Board then held at 4.35% in June and August while it assessed how those increases were flowing through the economy. The latest decision marks a return to tightening after that four-month pause.

Inflation risks pushed the RBA back to tightening

Australia’s most recent published inflation figures before the meeting showed some moderation in headline inflation but continued pressure underneath. The Australian Bureau of Statistics reported that the Consumer Price Index rose 3.5% over the 12 months to July, down from 3.8% in June. Trimmed mean inflation, which the RBA watches as a measure of underlying price pressure, was unchanged at 3.6%.

Those figures still left both headline and underlying inflation above the RBA’s 2% to 3% target range. The central bank also said recent inflation outcomes had been stronger than it expected at the August meeting. Its September statement did not rely on August CPI data, which had not yet been released when the Board made its decision.

The shift in tone is important because the RBA had already identified several upside risks in its August Statement on Monetary Policy. At that time, it expected headline inflation to remain elevated in the near term and projected trimmed mean inflation to stay above 3% until the middle of 2027. The August forecasts assumed that conflict-related energy pressures would ease over time and that financial conditions would remain somewhat restrictive.

By September, the Board said global energy prices were much higher than assumed in those forecasts. It also said liaison with businesses showed firms facing cost pressures were either lifting prices or considering doing so, while short-term inflation expectations remained elevated. Higher fuel prices had already been partially passed through to other goods and services. The RBA described that external cost pressure as an additional inflation impulse on top of capacity pressures already present in the domestic economy.

Weak productivity growth remains part of that domestic problem. When the economy’s capacity to produce goods and services grows slowly, demand can run into supply constraints more quickly. The RBA said aggregate demand needs to remain subdued for a period to reduce those pressures and return inflation sustainably to target.

Growth is slowing, but the economy has not weakened sharply

The rate increase comes as Australian economic growth has slowed. Gross domestic product rose 0.4% in the June quarter and 2.1% from a year earlier, according to the ABS. The RBA said the quarter was slightly stronger than it had expected, although the broader pace of output growth remains subdued.

Household demand is also showing signs of cooling. The central bank said consumer spending appears to be easing gradually, housing prices have fallen in most capital cities and new housing lending has declined noticeably. At the same time, business investment and business debt growth remain strong, giving the Board a mixed picture rather than evidence of a broad contraction in demand.

The labour market has softened, but it has not broken sharply. The unemployment rate rose to 4.6% in August from 4.5% in July. Employment increased by about 39,500 people over the month, while the participation rate rose to 67.1%. The RBA said labour-market conditions had eased broadly as expected and that leading indicators were broadly stable.

That mix helps explain why the Board was willing to tighten policy again despite weaker housing conditions and slower growth. It acknowledged that the three earlier rate increases had already tightened financial conditions and that the economy appeared to be slowing. Even so, it judged inflation was still too high and that further restraint was warranted to support a return to target within a reasonable period.

The cash rate is the RBA’s operational target for overnight borrowing between banks, but changes in the target feed through more broadly to financial conditions. Commercial lending and deposit rates are set by individual institutions, so the September decision does not mechanically determine the size or timing of any particular mortgage, business-loan or savings-rate change. The policy direction, however, is tighter than it was at the start of the year.

August CPI and the November meeting are the next tests

The next major data point arrives almost immediately. The ABS is scheduled to release August CPI figures on September 30, one day after the RBA decision. Those numbers will provide the first full inflation reading after July and will be important context for judging whether the stronger price pressures highlighted by the Board are broadening or easing.

The minutes of the September Monetary Policy Board meeting are scheduled for October 13. The RBA’s next policy meeting will run on November 2 and 3, with the rate decision due on November 3. The September statement kept the possibility of additional tightening open, saying the Board would raise the cash rate further if needed, but it did not commit to another increase.

For now, the 4.60% cash rate takes effect on September 30. Between then and the November meeting, the Board will receive another round of inflation, employment and activity data to assess against the higher energy costs, persistent underlying inflation and slowing domestic demand that shaped this decision.
