The Reserve Bank of Australia has issued a fresh warning that the booming data centre industry may stoke inflationary pressures across the economy, complicating its path for interest rate decisions. The central bank's caution comes as energy-intensive data centres multiply nationwide, driven by surging demand for cloud computing and artificial intelligence.

Analysts say the infrastructure boom—while vital for digital growth—risks overwhelming electricity grids and driving up business costs that could be passed to consumers. The RBA's observation adds a new dimension to the inflation debate, which has already been roiled by housing market softness and tax policy changes.

Auction clearance rates in Sydney and Melbourne have weakened, with some forecasts predicting house prices could fall by more than A$100,000 in those cities. Treasurer Jim Chalmers defended the government's approach, arguing that proposed capital gains tax adjustments are designed to reduce distortions rather than create new ones.

The RBA's focus on data centres underscores how technology growth is creating unexpected economic headwinds. Policymakers now face the delicate task of supporting digital infrastructure expansion while ensuring it does not reignite the inflation that central banks have worked for months to tame.

Critics contend that the government's housing policies, rather than data centre demand, remain the primary driver of inflation uncertainty. The Coalition has accused Labor of mismanaging the economy, while the Greens argue that tax reforms do not go far enough to address housing affordability.
