Australia is grappling with a significant slump in labour productivity, a trend that Reserve Bank of Australia (RBA) Governor Michele Bullock has identified as a core driver of persistent inflation and a major impediment to improving living standards. The RBA’s latest forecasts predict a decline in labour productivity, raising concerns about the nation’s economic trajectory and its ability to achieve sustainable growth without stoking inflationary pressures.

Understanding Australia’s Productivity Challenge

Labour productivity, a measure of economic output per unit of labour input, is fundamental to wealth creation and rising living standards. Historically, improvements in productivity have allowed economies to produce more goods and services with the same or fewer resources, leading to lower costs, higher wages, and increased prosperity. For instance, the invention of the heavy plough in Northern Europe around a thousand years ago dramatically increased food production per farm worker, driving down costs and enabling wage growth and the accumulation of surplus wealth.

However, the RBA’s updated forecasts indicate a concerning reversal of this trend. The central bank now projects Australia’s labour productivity to fall by 0.5 per cent in the second half of 2026. Governor Bullock has voiced apprehension, stating, “We’re concerned because the productive capacity of the economy is not growing. As long as the productive capacity of the economy isn’t growing, we cannot grow very fast without running into inflationary pressures.” This means that even with existing demand, a failure to increase output per worker will likely lead to higher prices for goods and services.

The Link Between Productivity, Inflation, and Interest Rates

The implications of declining productivity are far-reaching. For the RBA, it complicates the task of managing inflation and setting interest rates. If the economy’s capacity to produce goods and services is not expanding, any increase in demand can quickly outstrip supply, leading to price increases. This dynamic makes it riskier for the central bank to lower interest rates, as doing so could further stimulate demand and exacerbate inflation without a corresponding increase in productive capacity.

Essentially, weak productivity acts as a brake on economic growth. It limits the economy’s ability to expand without hitting capacity constraints, which then translate into higher prices. This situation means that achieving faster economic growth and tangible improvements in real living standards becomes significantly more challenging.

Factors Contributing to the Productivity Slump

Economists point to several factors that may be contributing to Australia’s productivity woes. One significant area of concern is the scale of government spending, which AMP chief economist Shane Oliver notes has reached record levels, accounting for approximately 28 per cent of gross domestic product (GDP). Oliver argues that this substantial government expenditure, particularly when directed towards the public sector, may be less efficient in generating output compared to private sector investment.

Furthermore, changes to investment tax policies have also raised concerns. An increase in taxes on capital gains, with rates potentially reaching between 30 and 47 per cent, could disincentivise the private investment crucial for productivity gains. Historically, investments in new technologies and equipment, such as advanced machinery or, in the modern era, high-tech manufacturing and artificial intelligence, have been key drivers of productivity growth. Policies that dampen investment may therefore hinder the adoption of innovations that could boost efficiency.

Oliver suggests that the economic landscape has shifted since the Global Financial Crisis (GFC) and the pandemic, with a growing expectation that government intervention is the primary solution to economic challenges. This trend, he believes, has led to policies that may inadvertently stifle private sector dynamism and innovation.

The Impact on Wages and Living Standards

The disconnect between inflation and wage growth, exacerbated by productivity issues, directly impacts the cost of living for Australians. Since 2021, consumer prices have risen by approximately 25 per cent, while average wages have only increased by about 19 per cent. This gap means that many households are experiencing a decline in their real purchasing power, making it harder to maintain or improve their living standards.

As Shane Oliver explains, when an economy is less efficient at increasing the supply of goods and services to meet demand, any uptick in spending is more likely to result in higher inflation rather than increased output. This was observed when private sector demand picked up, leading to an acceleration in price growth that outpaced wage increases.

Policy Pathways to Boost Productivity

Addressing Australia’s productivity slump requires a strategic policy focus on restoring incentives for investment and innovation. Shane Oliver proposes several measures:

• Limit Government Spending: Capping government expenditure at around 25 per cent of GDP and ensuring any additional spending is offset by cuts elsewhere.
• Tax Reform: Revising tax policies, particularly those affecting capital gains, to encourage rather than discourage private investment and entrepreneurship.
• Labour Market Deregulation: Implementing reforms to enhance labour market flexibility and efficiency.
• Incentivise Investment: Creating stronger incentives for businesses to invest in new technologies and adopt productivity-enhancing innovations.

While the recent government budget included some modest measures to encourage investment, critics argue that more substantial reforms are needed to counteract the negative impacts of tax changes and high levels of government spending.

The Path Forward

The RBA’s concern over declining productivity underscores a critical challenge for the Australian economy. Without a concerted effort to boost the nation’s productive capacity, achieving sustainable economic growth and meaningful improvements in living standards will remain elusive. While interest rates and inflation capture significant public attention, productivity is arguably the most fundamental driver of long-term wealth and prosperity. Addressing this issue is paramount for securing Australia’s economic future.
