The annual inflation rate in Australia decreased to 4% in the year through May, a reduction from 4.2% in the year through April, according to the Australian Bureau of Statistics. Concurrently, the trimmed mean measure of inflation rose to 3.6% in the year to May, up from 3.4% in the preceding period.

Fuel prices saw a decrease of almost 12% in May. However, home building costs increased by 0.9% during the month, with the annual rate of home building cost increases reaching 5.6%. Food and drink inflation accelerated to 3.3% in the year to May, an increase from 2.8% in April. Restaurant and takeout meal prices also rose by 4%.

Treasurer Jim Chalmers addressed the inflation data, stating, "We know that there are still inflationary pressures in our economy. But these numbers today are much better than the market expected, much better than forecast, and that's obviously a very good thing."

Sally Auld, chief economist at NAB, commented on the inflation figures. "This lower inflation print combined with further evidence the economy is slowing a bit more than thought means the RBA may take a less hawkish tone when they next meet," Auld said.

Shane Oliver, chief economist at AMP, indicated that potential future price increases could influence the Reserve Bank of Australia's decisions. "There's probably still more impact to come to food prices from higher fertiliser prices, and that's going to worry the RBA," Oliver said.

Financial markets have assigned a 32% probability to an interest rate hike on August 11, with a 56% chance of an increase by the end of the year.
