Treasury Defends Inflation Strategy Amid Fourth Rate Rise

Core Event: Fourth RBA Rate Hike and Treasury’s Response
The Reserve Bank of Australia (RBA) raised the cash rate to 4.60 % in its September-29, 2026 meeting, marking the fourth increase this year and the highest level since 2011. Treasurer Jim Chalmers defended the government’s fiscal approach, emphasizing that the rise reflects global oil price pressures from the Middle-East conflict rather than domestic spending. He reiterated the Treasury’s focus on “inflation” while acknowledging “substantial pressure” on households.
Background & Context
Labor entered its second term promising a shift from inflation-focused policy to productivity-driven growth. The government has simultaneously announced cost-of-living measures—free TAFE, bulk-billing GP visits, cheaper medicines, and student-debt relief—while asserting that spending cuts elsewhere create fiscal “room.”
Data & Statistics
- Cash-rate trajectory in 2026: 3.60 % (start of year) -> 3.85 % (Feb) -> 4.10 % (Mar) -> 4.35 % (May) -> 4.60 % (Sept).
- Annual headline inflation: reported at 3.5 % and 4 % for August.
- Underlying (trimmed-mean) inflation: 3.6 % (Australian Bureau of Statistics).
- Government spending: 26.9 % of GDP in 2025-26, the highest in four decades outside COVID.
- Budget deficit: $22.3 billion (0.8 % of GDP), $6 billion better than the May forecast.
- Revenue share of GDP: 24.1 % (tax receipts) rising to 26.1 % total receipts.
Criticism & Opposition
- Richard Holden, UNSW economics professor, accused the Treasury of “gaslighting the Australian public” and urged Chalmers to curb spending.
- Dr Phil Lowe, former RBA governor, argued that “government spending has been adding to demand progressively over time, and that’s putting upward pressure on inflation.”
Conflicting Reports & Gaps
Sources differ on the headline inflation rate for August: ABC reports 4 % while The Conversation cites 3.5 %. Both agree the underlying trimmed-mean figure stands at 3.6 %. No source provides a definitive breakdown of how much of the inflation surge is attributable to domestic demand versus global oil shocks, leaving the precise causal balance unresolved.
