The Australian Bureau of Statistics (ABS) is set to release the Consumer Price Index (CPI) for the September quarter on Wednesday at 11:30 a.m. AEDT. This figure is crucial for the Reserve Bank of Australia (RBA) as it will influence the decision on interest rates, particularly ahead of Melbourne Cup Day next week. If the CPI is higher than expected, it may hinder the RBA from cutting interest rates. Conversely, a lower-than-expected CPI could strengthen the case for a rate cut. Currently, market analysis suggests there is just under a 40% chance of a rate cut in November.

The CPI report includes several key figures, with the headline inflation rate and the core inflation rate being the most significant. The headline rate reflects the overall price changes in a basket of goods and services, while the core inflation rate, or "trimmed mean," excludes the most volatile items to provide a clearer picture of inflation trends. The RBA aims for a core inflation target of 2.5%, which is the midpoint of its target range of 2% to 3%.

In the June quarter, core inflation was recorded at 2.7%, slightly above the RBA's forecast of 2.6%. The RBA had previously lowered the cash rate by 0.25 percentage points in August, citing a decline in underlying inflation and stable labor market conditions. However, the bank has expressed concerns about the persistence of inflation in certain areas, particularly in the services sector, which includes healthcare, insurance, and rents.

Despite a rise in the unemployment rate to 4.5% in September, which exceeded the RBA's forecast of 4.3%, the RBA continues to describe the job market as "a little bit tight." This indicates ongoing upward pressure on wages, which are a significant concern for businesses. The National Australia Bank's quarterly report highlighted that wage costs remain the top issue affecting business confidence.

Economists are divided on the inflation forecast for the upcoming CPI data. Predictions range from a low of 0.7% to a high of 1.2% for the quarter. Westpac, one of the banks providing forecasts, anticipates a quarterly inflation figure of 1.1%. Some economists believe that a reading of 0.7% could be sufficient for the RBA to consider a rate cut.

RBA Governor Michele Bullock has indicated that the board will not be swayed by a single data point, such as the recent unemployment figure. The uncertainty surrounding the direction of unemployment adds complexity to the RBA's decision-making process. As the economy navigates these challenges, the upcoming CPI release will be closely watched for its potential impact on monetary policy and economic stability in Australia.
