The Reserve Bank of Australia (RBA) recently increased the cash rate by 0.25% to 4.35%. This marks the third consecutive increase, reinforcing what appears to be a front-loaded phase of policy tightening (more rate hikes skewed towards the start of the monetary policy tightening cycle).

While interest rate decisions reflect a range of economic factors, Australia’s current situation stands out relative to global peers.

Across other major economies, central banks such as the US Federal Reserve, the European Central Bank, and the Bank of Japan have taken a more cautious approach in recent months. Many have paused further rate increases as they assess the effects of earlier tightening and monitor the impact of higher global energy prices.

In contrast, Australia’s more acute domestic inflation challenge has led to a different policy path, setting it apart from many of its peers.

A different starting point for inflation

One important factor is the starting point. Australia entered the current global energy shock with inflation already above the RBA’s target range of 2% to 3%. By comparison, several other developed economies had seen inflation moderate closer to their targets before energy prices began to rise again.

Although inflation in Australia eased through parts of 2025, recent data suggest that progress has stalled. Measures of underlying inflation remain above target, indicating that price pressures are still present across the economy.

Trimmed mean inflation (underlying or ‘core’ inflation) was reported at 3.5% year-on-year in the March quarter, remaining above the target band. With energy prices expected to rise further in the near term, inflation risks may be skewed to the upside.

This highlights an important consideration. Inflation does not always follow a smooth downward path. Periods of improvement can be interrupted, particularly when global shocks interact with domestic constraints.

Supply-side constraints and productivity

A key feature of Australia’s inflation outlook is the role of supply-side constraints. This refers to the economy’s ability to grow without generating inflationary pressure.

Productivity growth has been relatively weak, which appears to have lowered the economy’s potential growth rate. In Vanguard’s view, even modest increases in demand may place upward pressure on prices. When growth outpaces the economy’s capacity to supply goods and services, inflation can re-emerge even after periods of easing.

Earlier signs of disinflation (slowing in the rate of inflation) in 2025 appeared to stall as these capacity constraints persisted. This suggests that supply-side factors continue to play a central role in shaping inflation outcomes.

Labour market pressures

Labour market conditions reinforce this picture. Australia’s unemployment rate has remained below estimates of full employment, indicating limited spare capacity [in the labour market].

There are signs the economy may be operating beyond its sustainable capacity. In this environment, competition for workers can intensify, supporting wage growth. While this can benefit households, it may also contribute to inflation if not matched by productivity gains.

There is also a risk that elevated inflation becomes more embedded in expectations. If households and businesses come to expect higher inflation, this may influence wage negotiations and price-setting behaviour, making inflation more persistent over time.

Fiscal policy and the broader economic environment

Fiscal policy may also influence the outlook into FY27. Recent Federal Budget projections point to a modest pullback in government support, partly reflecting stronger revenues linked to commodity exports.

While government spending may continue to rise as a share of GDP, the overall level of support to the economy appears to be moderating.

Higher taxation and reduced fiscal support could weigh on private sector activity, particularly in interest-sensitive sectors such as housing. This may contribute to a gradual slowing in economic growth, although the extent and timing remain uncertain.

More broadly, economic conditions reflect a combination of domestic and global factors, including household spending, business investment, and external demand. While some indicators point to softer momentum, the overall trajectory of growth remains unclear.

Role of global energy markets

The impact of rising energy prices on Australia is more nuanced than in many other countries. As a large net exporter of energy, higher commodity prices may support national income and government revenues.

This may partly offset the drag from weaker global demand and tighter financial conditions. At the same time, higher fuel and energy costs can affect households and businesses directly. Rising prices may reduce disposable income and increase operating costs, potentially weighing on consumption and investment.

As a result, the net effect of an energy price shock may be mixed, with both supportive and constraining influences across the economy.

What this could mean for interest rates

Looking ahead, the path of interest rates will likely hinge on how quickly the economy begins to weaken under the combined effects of higher borrowing costs and rising energy prices.

Recent data points to a sharp deterioration in consumer and business sentiment, suggesting that a downturn in activity may already be underway.

A base case scenario may be that the RBA pauses further rate increases through the remainder of the year, contingent on clearer evidence of slowing demand and some easing in labour market conditions.

However, if the economy proves more resilient than expected, or if inflation pressures persist, the risk of additional interest rate tightening may remain firmly on the table.

Conclusion

Australia’s current outlook highlights how differences in inflation dynamics, economic capacity, and exposure to global commodity markets can lead to divergent policy paths.

While some economies may be closer to stabilising [monetary] policy settings, Australia’s inflation challenge may take longer to resolve, particularly if supply-side constraints persist.

As a result, our domestic interest rate cycle may remain more uncertain than in other developed markets, reinforcing the importance of monitoring underlying economic conditions rather than assuming a uniform global trajectory.
