SYDNEY, 27 November 2025 — Australia may be running out of room for further monetary easing after recent activity and inflation data, prompting warnings that the RBA may soon consider raising interest rates instead of cutting them. Key economists highlight that the country’s economic “speed limit” might already be in sight.
Economic Signals Turning Cautionary
According to a recent report by Commonwealth Bank’s chief economist, strong growth, a resilient labour market, rising home prices and a surprise inflation uptick in the September quarter have complicated the outlook. The result: the RBA’s window for further rate cuts has likely closed, with the next move potentially being a hike.
Though the RBA lowered its cash rate multiple times in 2025, bringing it down to 3.60%, the full effect of those rate cuts is still filtering through the economy, particularly into housing credit and property markets.
At the same time, inflation has rebounded, pushing underlying price pressures above the RBA’s comfort zone. This inflation persistence, coupled with a tight labour market, is seen by some economists as a sign that the economy is operating close to or beyond its sustainable capacity, the so-called “speed limit.”
What “Speed Limit” Means for Policy
The concept of an economic “speed limit” refers to the maximum rate of growth an economy can sustain without triggering overheating, manifesting as rising inflation, asset bubbles (e.g. in real estate), or labour shortages.
If the economy is truly near that threshold, continuing with low interest rates risks stoking further inflation and other imbalances. For regulators and the RBA, this creates a delicate balancing act: attempting to support growth and employment, while safeguarding price stability and financial stability.
CBA’s view suggests that should economic momentum continue, the RBA could pivot to a “hiking bias”, potentially as soon as early to mid-2026.
Implications for Households, Businesses & Markets
- Homebuyers & mortgage holders: A rate hike cycle would raise borrowing costs, cooling demand for new mortgages and putting pressure on households with variable-rate debt.
- Property and construction sector: Rising financing costs could slow housing demand and dampen home-price growth, potentially easing inflationary pressure on rents and construction costs.
- Consumers and businesses: Higher rates may slow overall consumer spending and business investment, particularly in interest-rate sensitive sectors.
- Financial markets: Bond yields could rise, and equity valuations, especially of highly leveraged or rate-sensitive firms, may come under pressure. On the flip side, banking and financial firms might benefit from improved net interest margins.
- Monetary & fiscal tensions: The RBA’s likely policy shift will need to align carefully with government fiscal stance and cost-of-living pressures, especially as inflation affects households.
What to Watch Next
- Next RBA moves: The upcoming months will be crucial. Watch for RBA communications, labour-market data, inflation prints, and housing-market signals for clues on possible rate changes.
- Housing credit & property-price trends: Continued growth in housing credit or rapid home-price inflation could tilt the balance further toward tightening.
- Global headwinds: External factors, global economic slowdown, commodity price swings, or geopolitical risks — may influence Australia’s economic trajectory and constrain how far interest rates can rise without hurting growth.
- Policy coordination: As Australia heads potentially into a rate-hike phase, coordination between monetary and fiscal policies will be vital to manage cost-of-living pressures and maintain economic stability.
Overall, the message from economists: after a period of monetary easing and pro-growth policy, Australia’s next monetary pivot may be toward tightening, heralding a shift in the macroeconomic landscape as the nation navigates rising inflation, a strong labour market, and capacity constraints.
