Australia’s terms of trade declined again in the June quarter of 2026, highlighting the impact of changing global price conditions on national income.

According to the Australian Bureau of Statistics (ABS), the terms of trade fell 1.6% during the quarter, with the index declining to 94.8 from 96.3 in the March quarter.

The decline occurred as Import prices increased faster than export prices. Import prices rose 3.5% during the quarter, while export prices increased 1.9%.

For Australia, which has historically benefited from strong Commodity export prices, movements in the terms of trade are an important indicator of the country’s purchasing power from international trade.

Understanding the Terms of Trade

The terms of trade measures the relationship between export prices and import prices.

When export prices rise faster than import prices, Australia gains greater purchasing power from its International Trade because it receives more income from selling goods overseas relative to what it pays for imported products.

Conversely, when import prices rise faster than export prices, the country’s purchasing power from trade declines.

The measure does not track the Volume of goods produced or exported. Instead, it focuses on price movements and how they influence national income.

This distinction is important because Australia’s export volumes remained positive in the June quarter. ABS data showed export volumes increased 0.8%, supported by improved coal production.

Why the Decline Matters

Australia has historically benefited from periods of strong commodity prices, particularly across resources such as iron ore, coal and gas.

When commodity prices rise significantly, export Earnings increase, supporting company profits, government Revenue and broader economic activity.

A weaker terms of trade environment can reduce some of that benefit because exporters receive less relative purchasing power from their sales compared with the cost of imported goods.

However, a decline in the terms of trade does not automatically indicate economic weakness. The measure is influenced by global commodity cycles, Exchange Rate movements and changes in import costs.

Import Prices Drive Recent Pressure

The latest decline was largely linked to stronger growth in import prices.

Import prices increased 3.5% in the June quarter, exceeding the 1.9% rise in export prices.

Higher fuel and vehicle costs contributed to increased import expenses. Global energy market movements have become an important factor, with Brent Crude oil prices moving above USD 100 per barrel and increasing concerns about further pressure on energy costs.

Higher fuel prices can influence Australia’s trade position because the country remains dependent on imported fuel products.

The increase in import costs also contributed to broader Inflation concerns, particularly through transport and Business input expenses.

Impact on Mining and Export Industries

Resource companies are closely linked to changes in the terms of trade because export prices directly influence revenue conditions.

A decline in the terms of trade can create pressure on margins if export prices weaken relative to input costs.

However, the June quarter data suggests that export activity itself remained relatively resilient, with export volumes increasing.

For mining companies, the key factors to monitor are commodity prices, production levels, operating costs and global Demand conditions.

A lower terms of trade environment does not necessarily mean weaker export performance, but it can reduce the income generated from those exports.

Impact on Government Revenue

Commodity prices have historically influenced government revenue through company taxes and resource-related income.

During periods of strong commodity prices, higher export earnings can provide support for government finances.

A weaker terms of trade may reduce some of this support, particularly if commodity prices remain under pressure for an extended period.

However, government revenue is influenced by several factors, including economic growth, taxation settings and broader business conditions.

Impact on Households and the Economy

The terms of trade affects households indirectly through its influence on national income.

When export conditions are favourable, higher income generated from trade can support broader economic activity through business investment, employment and government revenue.

When trade conditions weaken, income growth may face additional pressure.

This comes at a time when Australian households are already managing higher borrowing costs and elevated inflation. The ABS monthly CPI indicator showed annual inflation at 3.5% in July 2026, while underlying inflation remained at 3.6%, both above the Reserve Bank of Australia’s 2–3% target range.

Commodity Boom: Slowing or Temporary Adjustment?

The recent decline in the terms of trade does not confirm that Australia’s commodity-driven income gains have ended.

Terms of trade movements are naturally cyclical and can change due to global commodity prices, energy markets and exchange rate movements.

Two consecutive quarterly declines indicate that the strong price advantage Australia previously enjoyed has moderated, but the longer-term direction will depend on future commodity and import price trends.

Global demand for Australian resources, energy prices and international economic conditions will remain important factors influencing the outlook.

Outlook

Australia’s terms of trade remains an important indicator of economic conditions because it reflects the country’s position in global markets.

The June quarter decline highlights the impact of higher import costs, particularly from energy and other imported goods.

While export volumes remained positive, weaker relative export pricing creates a more challenging environment for national income growth.

Future movements in commodity prices, global energy markets and trade conditions will determine whether the recent decline represents a temporary adjustment or the beginning of a longer trend.
