Australia Budget Deficit Beats Forecast as RBA Weighs 4.6% Rate
Treasurer Jim Chalmers and Finance Minister Katy Gallagher handed down the 2025–26 Final Budget Outcome on 28 September 2026, delivering an underlying cash deficit of $22.3 billion. The audited result marks a significant $6.0 billion improvement against the $28.3 billion shortfall projected in the May 2026 budget, equivalent to 0.8 per cent of gross domestic product. Total receipts landed $4.6 billion above expectations, propelled by resilient individual income tax collections and an unexpected windfall in superannuation earnings taxes, while federal payments finished $1.4 billion lower than forecast. Concurrently, gross debt closed the financial year at $924.2 billion—$10.6 billion below anticipated ceilings—providing the Albanese government with a temporary fiscal cushion.
Yet the celebratory mood inside the Treasury executive wing was quickly overshadowed by macroeconomic reality. While the bottom line outperformed treasury models, the $22.3 billion deficit marks a steep deterioration from the $10.0 billion deficit recorded in 2024–25, decisively ending any expectation of returning to the back-to-back surpluses achieved earlier in the parliamentary term. More acutely, the release landed on the eve of the Reserve Bank of Australia’s monetary policy board meeting on 29 September, where Governor Michele Bullock and board members face persistent services inflation and escalating global oil shocks.
With financial markets and commercial bank economists pricing an overwhelming probability that the RBA will lift the official cash rate by 25 basis points to a 15-year high of 4.60 per cent, the budget outcome underscores the acute friction between fiscal policy and monetary management. As Canberra celebrates a cyclical accounting win driven by bracket creep and superannuation yields, millions of Australian households face compounding mortgage stress. The divergence highlights a growing macroeconomic dilemma: a federal budget running structural deficits that central bankers warn risk stoking inflationary fires in our macroeconomic analysis.
