The data center construction boom may increase inflationary pressure, and the Reserve Bank of Australia may be forced to maintain high interest rates.

According to information from Zhihui Finance APP, James McIntyre, the Bloomberg Economics economist responsible for the Australian market, stated that the data center construction boom in Australia could result in demand outstripping the economy's supply capacity, leading to higher inflation and forcing the Reserve Bank of Australia to maintain higher interest rates.

In a research report, James McIntyre mentioned that the surge in data center spending may drive capital expenditure (Capex) above 2% of Australia’s gross domestic product (GDP) in fiscal year 2026-27. He believes the development of large-scale data center projects will intensify competition for construction capacity and attract skilled workers away from renewable energy development, infrastructure projects, and housing construction.

Capital expenditure forecasts show a surge in investment

He said: “As with other investment booms in Australia, this current expansion is crowding out activity in other areas, especially in non-residential construction. Electricity production, including renewable energy and transmission, data centers, and public infrastructure investment are exerting enormous pressure on other parts of the economy.”

After inflation and GDP data came in stronger than expected, the Reserve Bank of Australia is under renewed pressure to resume rate hikes, with its policy meeting only three weeks away. The central bank has consistently emphasized the need to return the economy to a balanced state, and between February and May had raised the cash rate three times in a row, to 4.35%, then paused rates afterwards.

According to data released last Wednesday by the Australian Bureau of Statistics, Australia's GDP grew by 0.4% quarter-on-quarter in the second quarter, higher than the expected 0.3%; and by 2.1% year-on-year, also beating forecasts of 1.8%. This data indicates that the Reserve Bank of Australia's previous measures to curb inflation and cool the economy have yet to significantly suppress economic activity, and will form an important basis for the central bank's assessment of whether to further tighten policy.

Meanwhile, Australia’s persistently high inflation has led economists from Goldman Sachs to Commonwealth Bank of Australia to forecast that the Reserve Bank could raise interest rates as early as this month, abandoning previous expectations for steady rates through the rest of the year. Commonwealth Bank of Australia stated that the inflation data will cause the Reserve Bank to “lose patience,” predicting a 25-basis-point rate hike to 4.6% in November, and also noting a possible move at the September 28-29 meeting. Economists from ANZ and Goldman Sachs also expect a November hike, with Goldman likewise seeing a risk of a rate increase in September. Deutsche Bank forecasts a September rate hike, characterizing underlying inflation as “unacceptably high.”

Ivan Colhoun, chief economist at CreditorWatch Pty Ltd., also expressed some of the same concerns as James McIntyre. He stated that the data center boom will put pressure on material prices, labor demand, and wages, “which means the softness in residential approvals and house prices is of lesser importance to monetary policy than it would usually be.”

However, James McIntyre pointed out that over time, these investments will ultimately bring productivity gains. He said: “The ongoing integration of drones and remotely operated heavy machinery may eventually replace some manual jobs in Australia’s capital-intensive mining and agriculture sectors.”
