The AI investment boom has arrived in the economic data

Artificial intelligence is moving from the technology headlines into the official economic statistics. New figures from America and Australia reveal substantial increases in investment in computing equipment, data centres and supporting infrastructure.

The latest US durable-goods report illustrates the scale of the expansion. Although total orders were virtually unchanged in August, core capital-goods orders increased 1.6% during the month and 14.1% over the year. Orders for computers and electronic products rose 16.5% annually, while machinery orders increased 15.1%. These broad categories include equipment required for AI infrastructure, alongside other industrial investment.

Australia is experiencing a similar investment surge.

The ABS reports that equipment investment in information, media and telecommunications increased an extraordinary 199.6% in the March quarter, driven by server racks and processing equipment for data centres.

Spending subsequently fell 53.0% in the June quarter as large equipment purchases were completed. Nevertheless, investment remained 93.5% higher than a year earlier. Construction investment in the same industry increased 64.9% over the year, reflecting continued expansion of data-centre capacity.

Across the Australian economy, equipment investment was 18.7% higher than a year earlier and total private capital expenditure was up 10.7%.

But there is an important distinction between capital expenditure and economic growth.

The ABS reports that substantial imports of data-centre equipment have offset much of the initial investment's contribution to Australian GDP. Domestic construction generates economic activity, but installing imported servers does not itself produce an equivalent increase in domestic output.

The larger potential benefits arise when Australian businesses use AI infrastructure to increase productivity.

For Australia, the economic question is therefore shifting from how many data centres are built to how effectively businesses exploit their capabilities.

The investment boom is already measurable. The productivity dividend remains to be demonstrated.
