Australia Commodity Prices YoY: December 2025 Analysis and Macro Outlook
Key Takeaways: Australia’s commodity prices declined by 1.70% YoY in December 2025, a sharper drop than the -1.30% recorded in November but better than the -2.00% consensus estimate. This marks a continued easing from the severe contractions seen earlier in 2025, with prices recovering from a low of -11.90% in February. The moderation in commodity price declines signals stabilizing external demand amid persistent global uncertainties. However, risks from geopolitical tensions and tightening financial conditions remain. The data suggests a cautiously optimistic outlook for Australia’s resource sector, with implications for monetary policy, fiscal planning, and market sentiment.

Australia’s commodity prices YoY fell by -1.70% in December 2025, according to the latest release from the Sigmanomics database. This decline is a slight deterioration from November’s -1.30% but remains an improvement compared to the steep drops earlier this year. The commodity price index has rebounded from a trough of -11.90% in February 2025, reflecting easing pressures on Australia’s key export sectors.
Drivers this month
- Iron ore and coal prices softened amid weaker Chinese industrial output.
- Base metals stabilized, supported by supply constraints and infrastructure demand.
- Energy commodities saw mixed performance due to volatile global oil markets.
Policy pulse
The current reading remains below the long-term average decline of -4.80% seen over the past 12 months but above the lows of early 2025. This suggests commodity price pressures are easing but still weigh on inflation and growth expectations. The Reserve Bank of Australia (RBA) is likely to maintain a cautious stance, balancing inflation control with growth support.
Market lens
Immediate reaction: The AUD/USD pair dipped 0.30% following the release, reflecting concerns over export earnings. Meanwhile, 2-year government bond yields edged down 5 basis points, signaling a modest risk-off sentiment in fixed income markets.
Commodity prices are a critical barometer for Australia’s macroeconomic health, given the country’s heavy reliance on resource exports. The YoY decline of 1.70% contrasts with the -11.90% plunge recorded in February 2025 and the -6.10% in May, indicating a gradual recovery trajectory.
Monetary Policy & Financial Conditions
The RBA’s recent tightening cycle has been influenced by inflationary pressures partly driven by commodity price volatility. The moderation in commodity price declines may ease input cost pressures, potentially allowing the central bank to pause rate hikes. However, ongoing global financial tightening and elevated bond yields continue to constrain credit conditions.
Fiscal Policy & Government Budget
Australia’s fiscal outlook remains sensitive to commodity price trends. Lower prices reduce export revenues, impacting government receipts and budget surpluses. The December print suggests some relief from the sharp revenue contractions earlier in 2025 but underscores the need for prudent fiscal management amid external uncertainties.
External Shocks & Geopolitical Risks
Geopolitical tensions in the Indo-Pacific and trade disruptions remain key downside risks. Any escalation could further depress commodity demand, particularly from China, Australia’s largest trading partner. Conversely, easing tensions or new trade agreements could boost commodity prices and export volumes.
Comparing the current print to the previous months, the commodity price index has shown a clear recovery from the mid-year slump of -7.70% in June and -9.00% in August. The November figure of -1.30% suggested a near-stabilization, but December’s slight dip signals ongoing fragility. The data aligns with global commodity price trends, where supply constraints and demand fluctuations have created a mixed outlook.
This chart reveals a commodity price trend that is trending upward from severe declines but remains vulnerable to external shocks. The recent moderation in price drops suggests a base for potential growth, though volatility persists.
Market lens
Immediate reaction: Following the release, the Australian dollar weakened modestly, reflecting concerns over export earnings. Commodity-linked equities such as BHP saw a slight pullback, while bond yields softened amid risk-off sentiment.
Looking ahead, commodity prices in Australia face a range of scenarios shaped by global demand, supply dynamics, and geopolitical developments. The baseline forecast anticipates a gradual return to positive growth in commodity prices by mid-2026, supported by infrastructure spending and supply constraints.
Bullish scenario (30% probability)
- Global economic recovery accelerates, boosting demand for metals and energy.
- Geopolitical tensions ease, improving trade flows.
- Supply disruptions persist, supporting higher prices.
Base scenario (50% probability)
- Commodity prices stabilize around current levels with modest upward momentum.
- RBA maintains steady monetary policy to balance inflation and growth.
- Fiscal policy remains cautious but supportive of key sectors.
Bearish scenario (20% probability)
- Global slowdown or recession reduces commodity demand.
- Escalating geopolitical risks disrupt trade and investment.
- Financial tightening pressures commodity-linked sectors.
Structural & Long-Run Trends
Long-term, Australia’s commodity prices are influenced by decarbonization trends, shifting global supply chains, and technological innovation. The transition to green energy may reshape demand for certain minerals, while climate policies could affect production costs and export patterns.
The December 2025 commodity prices YoY data from the Sigmanomics database highlights a cautiously improving outlook for Australia’s resource sector. While the -1.70% decline signals ongoing challenges, the trend away from the severe contractions earlier this year is encouraging. Policymakers must navigate a complex environment of global uncertainty, financial tightening, and structural shifts. Markets will closely watch commodity price trajectories as a key input for inflation, currency valuation, and fiscal health.
