Rising energy costs heighten inflation pressures as Australia’s central bank prepares for fourth straight rate hike next week

KUALA LUMPUR, 22 SEPTEMBER 2026 —

The Reserve Bank of Australia is poised to implement its fourth interest rate hike of the year next week, a move driven by rising energy prices that have exacerbated upside inflation risks.

Economists indicate that the central bank will raise its benchmark interest rate in response to persistent inflationary pressures, aligning with a broader global trend of monetary tightening.

This decision shows the urgency for policymakers to contain price growth as energy costs continue to feed into the broader economy, creating a challenging environment for both consumers and businesses.

The anticipated rate increase in Australia is part of a synchronized global response to inflation that has remained stubbornly above target levels in major economies. As the Reserve Bank of Australia prepares to act, it joins a cohort of central banks, including the European Central Bank, the Reserve Bank of New Zealand, and the US Federal Reserve, in raising rates.

This coordinated tightening reflects a shared assessment that inflationary pressures are not yet sufficiently under control, necessitating further monetary policy adjustments to anchor expectations and stabilize prices.

In the United States, the Federal Reserve is expected to raise interest rates by 25 basis points this week, marking its first hike since 2023. This move potentially signals further tightening over the coming months, as policymakers respond to economic data and hawkish guidance. The decision follows a series of strong indicators, including employment data and a hawkish address by Federal Reserve Chair Kevin Warsh at the Jackson Hole symposium.

These factors have strengthened market expectations for a September increase, with US money markets currently assigning a high probability to the hike.

Mark Dowding, chief investment officer for fixed income at RBC BlueBay Asset Management, noted that the hawkish speech from Kevin Warsh at Jackson Hole has cemented expectations for a September rate hike.

He stated that with markets currently assigning a 70 per cent chance of a hike at next week’s Federal Open Market Committee meeting, a consensus-aligned inflation report would push Warsh and the board to hike rates by 0.25 per cent to 3.75-4.00 per cent.

Dowding emphasized that the latest US employment report showed the economy adding 162,000 jobs in August, a figure materially above the consensus estimate and further evidence that US economic activity remains relatively.

Following the release of stronger-than-expected underlying August inflation data, US money markets increased the probability of a 25-basis-point hike to 86 per cent. Markets priced in about 3.5 increases by June next year, reflecting expectations of a sustained tightening cycle. This pricing action indicates that investors anticipate the Federal Reserve will continue to raise rates well into the next year, rather than pausing after the September move.

The shift in market sentiment highlights the significant impact of recent economic data on forward-looking monetary policy expectations.

Shane Oliver, chief economist at AMP, said the Fed was likely to join central banks including the European Central Bank, the Reserve Bank of New Zealand, and the Reserve Bank of Australia in raising rates. He pointed out that inflation remained above the Fed’s 2 per cent target, with core consumer price inflation running at 2.4 per cent annually.

Estimated core personal consumption expenditure inflation stood at about 3.2 per cent, indicating that underlying price pressures remain elevated. These figures underscore the challenge facing the Federal Reserve in bringing inflation back to its target level without causing excessive economic slowdown.

Oliver noted that the Fed’s June meeting showed half of the Federal Open Market Committee’s officials expected an increase this year, while the central bank had dropped its easing bias. He argued that the upside surprise in August inflation was inconsistent with policymakers’ requirement for a declining inflation trend. This discrepancy between data and policy expectations suggests that the Federal Reserve may need to act more aggressively to align inflation trajectories with its targets.

The removal of the easing bias signals a shift in the central bank’s stance, prioritizing inflation control over potential economic support.

Although the Fed was expected to leave the prospect of additional tightening open, AMP’s base case was for only one further increase after September, most likely in December. This projection suggests that while the September hike is certain, the pace of subsequent tightening may moderate. The central bank is likely to assess the impact of the September move on economic activity and inflation before deciding on further actions.

This cautious approach reflects the delicate balance between controlling inflation and maintaining economic stability.

Dowding said higher borrowing costs had not yet caused a material deterioration in economic growth, but their effect on exposed parts of the economy would require closer attention.

He stated, “We continue to see few signs of higher borrowing costs adversely impacting economic growth, but this is something we may need to be attentive towards, particularly with respect to passthrough onto interest rate-sensitive sectors.” This observation highlights the potential lag in the transmission of monetary policy to the real economy, where the full impact of rate hikes may not be immediately visible in growth metrics.

The focus on interest rate-sensitive sectors is as higher borrowing costs can disproportionately affect industries such as real estate, construction, and consumer discretionary spending. These sectors are more vulnerable to changes in interest rates, and any deterioration in their performance could have broader implications for economic growth. Monitoring these areas will be essential for policymakers to gauge the effectiveness of their tightening measures and to adjust their strategies if necessary.

The interplay between monetary policy and sector-specific dynamics remains a key area of analysis for economists and investors.

The European Central Bank’s recent decision to raise rates further illustrates the global nature of the current inflationary challenge. While specific details of the ECB’s move are not elaborated in the source, its inclusion in the list of central banks raising rates underscores the widespread nature of the response. This global synchronization suggests that inflationary pressures are not isolated to one region but are a systemic issue requiring coordinated action.

The actions of the ECB, along with the Federal Reserve and the Reserve Bank of Australia, reflect a unified approach to combating inflation across major economies.

For Malaysia and the wider region, the global tightening cycle presents both challenges and opportunities. Higher global interest rates can lead to capital outflows from emerging markets, putting pressure on local currencies and increasing borrowing costs for businesses and consumers. However, a stable global economic environment, supported by effective inflation control, can also foster long-term growth and investment. Regional policymakers will need to carefully navigate these external pressures while addressing domestic economic conditions.

The interplay between global monetary policy and regional economic dynamics will be a critical factor in shaping the future economic landscape.

The upcoming decisions by the Reserve Bank of Australia and the Federal Reserve will be closely watched by markets and policymakers alike. The outcomes of these meetings will provide valuable insights into the trajectory of global monetary policy and its impact on economic growth and inflation. As the world continues to grapple with the aftermath of the pandemic and ongoing geopolitical tensions, the role of central banks in stabilizing economies and managing inflation remains paramount.

The next few months will be in determining the effectiveness of these measures and their long-term implications for the global economy.
