RBA rate hikes may not curb inflation, experts suggest alternatives
Analysts argue that recent interest-rate increases are unlikely to reduce inflation and propose fiscal measures such as a higher GST or increased superannuation contributions as possible alternatives.
The Reserve Bank of Australia's (RBA) planned interest-rate increase is viewed by some economists as unlikely to lower inflation effectively. They note that while higher rates reduce disposable income for mortgage borrowers, they simultaneously increase returns for outright homeowners, potentially offsetting the intended contractionary impact.
Mortgage borrowers represent roughly one-third of Australian adults, a share matched by outright homeowners, who may channel higher investment earnings into discretionary spending. Additionally, housing accounts for about 25% of the consumer price index (CPI) weighting, with construction costs and rents influencing the measure. Higher rates can prompt landlords to raise rents to cover borrowing costs, which may then feed back into CPI calculations and sustain inflationary pressure.
Commentators suggest alternative policy tools, including raising the Goods and Services Tax (GST) to 15% or increasing compulsory superannuation contributions from the current 12% to 14% or 15%. Both options would reduce household disposable income but would require legislative action and broader political support.
The discussion highlights a broader debate over the reliance on monetary policy alone to manage inflation and calls for consideration of additional fiscal levers.
