“Booming Government Spending” Will Force RBA to Hike Again

Key Takeaways

• RBA lifted cash rate 0.25% in February amid high inflation.
• Governor Bullock cites government spending as key inflation driver.
• UBS forecasts another rate hike to 4.6% by August.
• Fiscal stimulus and tight monetary policy create “burnout economy” risk.

Pulse Analysis

Australia’s inflation trajectory has been shaped by a potent mix of supply constraints and surging demand, the latter amplified by aggressive fiscal outlays. Even before the February 2026 Middle‑East conflict, underlying price growth hovered above the Reserve Bank of Australia’s 2‑3% comfort zone, prompting a modest 0.25 percentage‑point rate increase. Governor Michele Bullock’s recent testimony underscored that expansive government programs—particularly broad cost‑of‑living support—have added measurable pressure to the economy’s capacity limits, setting the stage for tighter monetary policy.

The prospect of a second RBA hike, projected by UBS chief economist George Tharenou to lift the cash rate to roughly 4.6% by August, carries concrete implications for the Australian financial landscape. Higher rates translate into more expensive mortgages, elevated corporate borrowing costs, and a likely slowdown in residential and commercial investment. Equity markets may react to the tightening signal with increased volatility, while the Australian dollar could appreciate as yield differentials rise. For consumers, the cost‑of‑living squeeze intensifies, prompting a shift toward discretionary spending cuts that could further dampen GDP growth.

Policymakers now face a delicate balancing act. While the federal and state budgets remain expansionary—described by analysts as a “boom” in spending—such fiscal vigor runs counter to the RBA’s brake on demand. This misalignment risks a “burnout economy,” where growth stalls under the weight of high rates and persistent fiscal stimulus. Coordination between the Treasury and the central bank will be crucial to avoid a prolonged period of elevated inflation and subdued growth, and to restore confidence that monetary tightening will be effective without triggering a sharp economic contraction.
