Australia’s annual inflation rate has climbed to 4.3 per cent, increasing pressure on the Reserve Bank of Australia (RBA) to lift interest rates for a fifth time this year, as persistent price pressures raise fresh concerns about housing affordability and borrowing costs.
The latest Australian Bureau of Statistics (ABS) figures show headline inflation increased from 4 per cent in August to 4.3 per cent in September, while annual trimmed mean inflation, which removes extreme price movements, rose to 3.6 per cent from a revised 3.5 per cent.
The figures have intensified expectations of another 0.25 percentage point increase when the RBA meets on 2 and 3 November, a move that would take the official cash rate from 4.6 per cent to 4.85 per cent.
However, Compare the Market Economic Director David Koch has questioned whether further increases are the right response, arguing that mortgage holders are already carrying a disproportionate share of the financial burden.
“The problem is inflation is stuck despite four rate rises. It’s not slowing despite the financial pain inflicted on average Australian households. The challenge is what can we do to break the impasse? Rate rises haven’t worked so far,” Mr Koch said.
“Should homeowners be the ones to carry the full burden? Right now, it’s the only lever the RBA has, but I think governments at all levels need to start picking up the slack.”
According to Compare the Market, mortgage holders with a loan of approximately $731,000 are already paying an additional $464 a month following four 0.25 percentage point increases this year.
The company’s calculations suggest another increase of the same size would add approximately $114 to monthly repayments, bringing the cumulative increase to $578 a month, or almost $7,000 annually.
For the property industry, another rate rise could place further pressure on borrowing capacity and housing affordability, potentially influencing buyer budgets, purchasing decisions and transaction activity.
Inflation complicates the RBA’s next move
The latest figures present a difficult decision for the RBA, which must balance the need to bring inflation back within its 2 to 3 per cent target against the financial pressure already being experienced by households.
The September data showed annual headline inflation rising for a second consecutive month, while underlying inflation also increased, indicating that price pressures remain persistent.
Financial comparison group Canstar has highlighted the financial impact of higher interest rates on Australian borrowers, while economic commentators have pointed to the challenge of controlling inflation without placing additional pressure on household spending.
International financial services firm Ebury has also examined the implications of persistent inflation for monetary policy, with the latest figures adding to expectations that the RBA may need to keep interest rates elevated.
The competing pressures are particularly relevant to the housing market, where changes in interest rates can affect both existing mortgage holders and prospective purchasers.
Mr Koch said the distinction between headline and underlying inflation remained important when considering the RBA’s next move.
“Last week I said 3.6% was the magic number for trimmed mean inflation – if it came in any higher, I would say that a hike was almost a certainty. At 3.6%, we’re still in a bit of a grey area ahead of the RBA’s November meeting, and the Reserve Bank could decide to watch and wait given the equally concerning rise in unemployment.”
He also pointed to fuel prices as a significant contributor to the latest inflation result.
“Headline inflation is clearly troubling – and if you look at the driving forces, there are several factors at play. Fuel remains one of the biggest headaches, with the fuel excise relief having rolled off as oil prices surged.”
Housing costs remain a major inflation driver
Housing remained one of the largest contributors to annual inflation in September, with costs increasing 5.2 per cent over the year, while transport prices rose 8.7 per cent.
The ABS data also revealed differences between capital cities, with annual inflation ranging from 4 per cent in Melbourne to 5.3 per cent in Hobart.
Sydney recorded annual inflation of 4.3 per cent, while Brisbane reached 4.4 per cent, Perth 4.5 per cent and Adelaide 5 per cent.
The figures highlight the uneven nature of inflation across the country, with housing and transport costs contributing to household financial pressures.
For property buyers and existing mortgage holders, the prospect of another interest rate increase adds to the challenge of managing housing costs, particularly where borrowing capacity is already constrained.
What another rise means for real estate
The November decision could have implications beyond higher mortgage repayments, particularly as buyers reassess their borrowing limits and vendors adjust their expectations around demand.
Higher interest rates can reduce the amount prospective purchasers are able to borrow, while existing homeowners considering upgrading may face increased financing costs and tighter household budgets.
Property investors could also face additional holding costs, particularly those with variable-rate loans, potentially influencing purchasing decisions and investment strategies.
However, the impact on individual property markets will depend on local supply, demand and buyer demographics, with the latest inflation figures alone providing no certainty about future property price movements.
With the RBA’s next decision only days away, the central question is whether another increase will meaningfully slow inflation or simply place further financial pressure on households already absorbing the effects of four rate rises this year.
