The latest release from the Sigmanomics database shows Australian business inventories declined by 0.90% quarter-on-quarter in Q4 2025, a sharp reversal from the modest 0.10% rise in Q3 and well below the 0.30% consensus forecast. This marks the steepest quarterly drop since the 1.90% contraction in Q3 2023. Over the past year, inventories have fluctuated, with notable expansions in Q4 2024 (1.30%) and contractions in Q1 2024 (-1.70%).

Drivers this month

• Slowing consumer demand amid rising interest rates.
• Supply chain normalization reducing the need for excess stock.
• Businesses adopting leaner inventory strategies to preserve cash.

Policy pulse

The Reserve Bank of Australia’s (RBA) restrictive monetary stance, with cash rates steady at 4.10%, continues to tighten financial conditions. This discourages inventory buildup due to higher financing costs. Fiscal policy remains neutral, with no major stimulus announced in the recent budget cycle.

Market lens

Following the print, the Australian dollar (AUDUSD) dipped slightly by 0.15%, reflecting cautious sentiment. Short-term bond yields edged lower, signaling some growth concerns, while equity markets showed muted reaction.

Business inventories are a critical component of GDP and supply chain health. The contraction in Q4 2025 contrasts with the broader economic backdrop where GDP growth slowed to 1.20% annualized in Q3 2025. Retail sales growth decelerated to 0.30% MoM in November, while manufacturing PMI slipped below 50, indicating contraction.

Monetary Policy & Financial Conditions

The RBA’s firm stance to combat inflation, which remains above the 2–3% target band at 3.80% YoY, has increased borrowing costs. Business lending rates rose to 6.50%, pressuring working capital and inventory financing. Credit growth slowed to 2.10% YoY, the weakest since 2022.

Fiscal Policy & Government Budget

Australia’s 2025 budget maintained a neutral fiscal stance, with a slight deficit of 0.40% of GDP. No new incentives for business investment or inventory buildup were introduced. Infrastructure spending continues but with a long-term horizon, limiting immediate impact on inventories.

External Shocks & Geopolitical Risks

Global trade tensions and supply chain disruptions persist, especially with China’s slower growth and ongoing geopolitical frictions in the Indo-Pacific region. These factors contribute to cautious inventory management by Australian firms.

Drivers this month

• Inventory drawdowns in wholesale trade (-1.20%) and manufacturing (-1.00%).
• Retail inventories remained flat, reflecting steady but cautious demand.
• Transport and warehousing sectors reduced stock levels amid cost pressures.

Policy pulse

The inventory decline reinforces the RBA’s view that demand-side pressures are easing, supporting a possible pause in rate hikes. However, inflation risks remain, keeping policy on a cautious footing.

Market lens

Immediate reaction: AUDUSD slipped 0.15% post-release, while 2-year government bond yields fell 5 basis points, reflecting increased growth concerns. Equity indices showed limited movement, indicating mixed investor sentiment.

Looking ahead, business inventories will be a key barometer for Australia’s economic momentum. The current contraction suggests firms are cautious about overstocking amid uncertain demand and higher costs.

Bullish scenario (20% probability)

• Global trade stabilizes, boosting export demand.
• RBA signals rate cuts in H2 2026, easing financing costs.
• Business confidence rebounds, leading to inventory restocking.

Base scenario (60% probability)

• Gradual economic growth with stable but cautious inventory management.
• Monetary policy remains on hold, balancing inflation and growth risks.
• Supply chains normalize, limiting inventory volatility.

Bearish scenario (20% probability)

• Global slowdown deepens, reducing demand sharply.
• Further monetary tightening to combat inflation spikes.
• Inventory drawdowns accelerate, pressuring GDP growth.

Businesses and policymakers should monitor inventory trends closely, as sustained declines could foreshadow broader economic weakness. Conversely, a rebound in inventories would signal renewed confidence and growth potential.

Australia’s Q4 2025 business inventories contraction underscores the cautious stance of firms amid tightening financial conditions and external uncertainties. While not yet alarming, the trend warrants close attention as it may presage slower GDP growth. Monetary policy remains a key influence, with the RBA balancing inflation control against growth risks. Fiscal policy’s neutral stance limits immediate support, while geopolitical tensions add downside risks. Structural shifts toward leaner supply chains continue to restrain inventory accumulation, reflecting a longer-term trend beyond cyclical factors.

Overall, the data suggests a cautious but stable economic environment, with risks skewed slightly to the downside. Market participants should watch for inventory trends as an early indicator of economic shifts in 2026.
