Aluminum Prices Remain High Despite Inventory Depletion in 2025

Why Are Aluminum Prices Hovering at High Levels?

The global aluminum market continues to experience elevated price levels, with SHFE aluminum trading between 20,500-21,000 yuan/mt and LME aluminum between $2,550-$2,660/mt. This persistent strength comes despite challenges in downstream demand, pointing to significant structural factors supporting current valuations.

The Current State of Aluminum Pricing

Current aluminum pricing reflects a complex interplay between production economics and market dynamics. With average fully-loaded production costs now reaching 16,550 yuan/mt (an increase of 80 yuan/mt week-over-week), the cost floor continues to rise. This upward pressure stems primarily from increases in spot alumina prices, a critical raw material input for aluminum production.

Despite these elevated market prices, smelter profit margins have actually decreased by approximately 120 yuan/mt over the past week. This profit compression highlights the squeeze producers are experiencing even in a high-price environment, as input costs continue to climb faster than finished product prices.

According to Shanghai Metal Market (SMM) analysis: "The current price levels provide adequate margins for most producers, but the trend of diminishing profitability bears watching as cost pressures mount."

Key Macroeconomic Factors Supporting Prices

China's economic trajectory remains a fundamental pillar supporting aluminum prices. The National Development and Reform Commission (NDRC) recently highlighted that China's economic growth during the 14th Five-Year Plan period is expected to exceed 35 trillion yuan, with 2025's total economic output projected to reach approximately 140 trillion yuan.

This robust growth outlook underpins industrial metal demand across sectors. Additionally, Beijing has implemented new consumer subsidy policies aimed at stimulating domestic consumption, though these measures will require time to fully materialize in terms of metals demand.

On the international front, trade disruptions are creating significant market uncertainty. Recent tariff impact analysis targeting major aluminum-producing countries will take effect on August 1, 2025, with varying rates:

• Brazil facing a substantial 50% tariff
• Libya, Iraq, Algeria, and Sri Lanka facing 30% tariffs
• Brunei and Moldova subject to 25% tariffs
• Philippines experiencing 20% tariffs

These follow earlier tariff implementations (25-40% rates) affecting Japan and South Korea, further complicating global aluminum trade flows and potentially limiting import competition in key markets.

How Is Inventory Depletion Affecting the Aluminum Market?

One of the most significant bullish factors supporting current aluminum prices is the ongoing depletion of inventories across major trading hubs. This drawdown represents a notable shift in market dynamics that has caught the attention of traders and analysts alike.

Current Inventory Trends

As of July 10, 2025, domestic aluminum social inventory stands at 466,000 metric tons, having decreased by 12,000 metric tons just since Monday of the same week. This accelerating depletion marks a critical transition in market patterns from inventory accumulation to consistent drawdowns.

SMM analysis identifies insufficient arrivals of new material as the primary driver behind this inventory reduction: "Despite being in a traditional off-season period, aluminum prices and inventory depletion continue to decline due to the combination of regular shipment schedules and lower-than-expected arrival rates of fresh metal."

This inventory situation creates a fundamental support mechanism for prices. With less metal available in warehouses, spot market dynamics tighten, and price sensitivity to supply disruptions increases significantly.

Production Capacity Dynamics

Contributing to the inventory situation are several structural shifts in production capacity. The liquid aluminum production ratio has fallen to 74.78%, continuing a downward trend that suggests operational adjustments at major smelters. Simultaneously, there has been an increase in ingot casting volume as producers respond to market conditions.

A significant factor in this production landscape is the ongoing Shandong-Yunnan replacement project, which is implementing a "stop first, start later" approach. This methodology involves decommissioning older, less efficient capacity in Shandong province before bringing new capacity online in Yunnan, creating a temporary reduction in overall output during the transition.

As one industry insider noted: "The replacement project creates a deliberate gap in production that, while temporary, coincides with other supply constraints to accelerate inventory drawdowns."

These capacity shifts, when combined with logistics challenges affecting new material arrivals, create a perfect storm for inventory depletion that underpins current price levels despite seasonal demand weakness.

What Supply-Side Factors Are Influencing Aluminum Prices?

The supply side of the aluminum equation remains a dominant force in current market dynamics, with several key factors exerting upward pressure on prices despite seasonal demand lulls.

Production Cost Analysis

A detailed examination of production economics reveals that aluminum smelting costs continue their upward trajectory. The average immediate fully-loaded production cost now stands at 16,550 yuan/mt, representing an increase of 80 yuan/mt week-over-week. This rise stems primarily from increases in spot alumina prices, which comprise approximately 30% of aluminum's total production cost.

The cost structure breakdown indicates that while energy and carbon inputs have remained relatively stable, the alumina component continues to apply upward pressure. This has resulted in profit margin compression for smelters, with margins decreasing by approximately 120 yuan/mt week-over-week despite elevated aluminum prices.

SMM's cost analysis notes: "The spread between market prices and production costs represents the effective floor for aluminum valuations, with current margins still providing adequate incentive for continued production despite recent compression."

This production cost dynamic creates a natural support level for prices around 16,550 yuan/mt, as sustained trading below this threshold would push significant production capacity into unprofitable territory.

International Trade Disruptions

Global aluminum flows face significant disruption from new tariff implementations scheduled for August 1, 2025. These trade barriers create artificial constraints on supply in major consuming markets and redirect global metal flows.

The US-China trade war continues to influence market dynamics, with cascading effects felt throughout the supply chain. Furthermore, the tariff structure varies considerably by country:

These tariffs follow previous measures targeting other major aluminum suppliers and create cascading effects throughout global supply chains. With alternative supply sources limited in the short term, these trade barriers effectively segment the global aluminum market and support regional price premiums.

The implementation timing is particularly significant as it coincides with already tight inventory conditions, potentially exacerbating physical market tightness in the coming months as traders adjust procurement strategies ahead of the August 1 effective date.

How Is Demand Affecting the Aluminum Market?

While supply factors and inventory depletion dominate current price dynamics, demand patterns remain crucial for understanding the complete market picture and future price trajectories.

Seasonal Demand Patterns

The aluminum market currently finds itself in a deep off-season period, traditionally characterized by reduced industrial activity and lower metal consumption. This seasonal lull would typically exert downward pressure on prices, making the current price strength even more remarkable.

High aluminum prices have further suppressed purchasing activity beyond normal seasonal patterns. Buyers facing elevated input costs have adopted a cautious stance, limiting procurement to essential near-term requirements rather than building inventory positions.

SMM market analysis indicates: "The combination of seasonal weakness and price-driven demand destruction creates a concerning demand picture that would typically pressure prices downward, making the inventory-driven price support even more significant."

Operating rates across the aluminum processing sector remain consistently weak, reflecting both seasonal factors and US economic pressures faced by downstream manufacturers grappling with high input costs and uncertain end-market demand.

Sector-Specific Demand Analysis

Drilling into specific demand segments reveals nuanced patterns across aluminum-consuming industries:

The photovoltaic (PV) sector, a significant aluminum consumer for frame components, presents a mixed picture. Module production schedules for July are expected to remain stable month-over-month, suggesting steady underlying demand. However, aluminum border frame manufacturers have begun voluntarily reducing orders due to operating losses caused by high input costs and compressed margins.

Industry Insight: PV frame manufacturers operate on thin margins that become unsustainable when aluminum prices exceed certain thresholds. Current pricing has pushed many producers into loss-making territory, forcing production curtailments despite stable end-market demand.

In the broader aluminum processing sector, spot market premium/discount trends continue to widen, indicating growing imbalances between primary aluminum availability and actual downstream demand. This widening spread serves as a market signal of dysfunction and suggests that current price levels may face eventual downward pressure once inventory dynamics normalize.

These sector-specific challenges underscore that current price strength stems primarily from supply constraints and inventory dynamics rather than robust demand fundamentals.

What Factors Will Drive Future Aluminum Price Movements?

Looking ahead, aluminum market participants are closely monitoring several key factors that will determine whether current price levels are sustainable or due for correction.

Short-Term Price Drivers

The most immediate price determinant is the sustainability of current inventory depletion trends. Market analysts emphasize the need for continued verification of drawdown patterns to confirm this isn't a temporary anomaly. Should inventory levels stabilize or begin rebuilding, a significant price support factor would be removed.

Arrival rates of new material into major warehousing hubs represent another critical short-term variable. The current insufficient arrival situation appears to stem from a combination of production adjustments and logistical constraints. Any normalization in these flows would likely halt the inventory drawdown and potentially reverse recent price support.

Off-season demand recovery timing also bears close watching. The market currently sits in a seasonal trough, but the transition toward autumn typically brings improved consumption patterns. The strength and timing of this seasonal uptick will significantly influence price trajectories through the remainder of 2025.

Market Perspective: "The interplay between inventory trends and seasonal demand recovery will determine whether current price levels represent a new sustainable range or a temporary spike awaiting correction once supply chains normalize." – SMM Analysis

Long-Term Market Outlook

The broader market outlook remains cautiously positive, with several structural factors providing fundamental support for aluminum valuations:

The domestic Chinese macro environment continues to display resilience and growth potential, with NDRC projections suggesting robust economic expansion through the remainder of the 14th Five-Year Plan period. This underlying economic strength provides a floor for industrial metals demand despite short-term fluctuations.

International trade tensions, while creating near-term disruptions, are reshaping global aluminum flows in ways that may support regional premiums and price differentiation across major markets. The August 1 tariff implementations will trigger a significant reconfiguration of trade patterns that will take months to fully materialize.

Production cost trajectory remains on a slight upward incline, with raw material prices and energy costs unlikely to see significant reductions in the coming quarters. This rising cost floor continues to provide fundamental valuation support for aluminum prices.

Environmental policy developments also merit attention, as carbon-related costs increasingly impact aluminum production economics, particularly in regions with strict emissions regulations. This growing cost component adds another layer to the production cost floor supporting prices.

FAQ About Aluminum Market Trends

What is causing aluminum inventory to decrease?

The primary driver behind aluminum inventory depletion is the insufficient arrival of new material into major warehousing hubs, combined with regular shipment schedules continuing to draw down existing stocks. This imbalance stems from:

• Production adjustments including the Shandong-Yunnan replacement project implementing a "stop first, start later" approach
• Shifts in production methodology with decreasing liquid aluminum ratios (now 74.78%) and increasing ingot casting
• Logistical constraints affecting the movement of metal between production centers and consumption hubs

This depletion pattern represents a significant shift from previous inventory accumulation trends and provides fundamental support for current price levels despite seasonal demand weakness.

How are high aluminum prices affecting downstream industries?

High aluminum prices are creating substantial challenges across downstream sectors, with several specific impacts:

• Reduced purchasing activity: Buyers have adopted a cautious stance, limiting procurement to essential near-term requirements
• Operating rate depression: Aluminum processing operations continue to run at reduced capacity due to margin pressures
• Voluntary order reductions: Some manufacturers, particularly in the PV border frame segment, are actively cutting production despite stable end-market demand due to unsustainable input costs
• Widening spot premiums/discounts: Market imbalances are reflected in growing disparities between spot and contract pricing

These downstream pressures create a potential ceiling for aluminum prices, as sustained high input costs eventually force production curtailments that reduce metal demand.

What role do international tariffs play in the aluminum market?

The implementation of new tariffs by major economies (ranging from 20% to 50%) is creating significant disruption in global aluminum trade flows. These measures:

• Create artificial supply constraints in affected markets
• Redirect global metal flows toward non-tariffed destinations
• Support regional price premiums in protected markets
• Force supply chain reconfiguration and procurement strategy adjustments

The August 1, 2025 implementation date serves as a critical market inflection point requiring careful monitoring as these policies take effect and market participants adjust trading patterns accordingly.

How sustainable is the current price level for aluminum?

The sustainability of current aluminum prices depends on several key factors:

• Inventory verification: Continued confirmation of depletion trends is essential for price support
• Arrival normalization: Any resolution of logistical or production constraints could rapidly alter inventory dynamics
• Seasonal demand recovery: The strength and timing of post-summer demand upticks will determine medium-term price trajectories
• Production cost evolution: The rising cost floor (currently 16,550 yuan/mt) provides fundamental support against significant price corrections

While inventory depletion provides solid near-term support for current price levels, the combination of seasonal demand weakness and margin pressure on downstream industries suggests potential vulnerabilities should supply dynamics normalize.

Comparative Analysis: Aluminum vs. Other Metals

Understanding aluminum's position relative to other major metals provides valuable context for current market dynamics and future price expectations.

Aluminum's current strength despite seasonal demand weakness distinguishes it from other industrial metals, highlighting the significance of the ongoing inventory depletion dynamic. While copper benefits from supply disruptions and steel from raw material stability, aluminum's price support stems primarily from the unexpected inventory drawdowns coinciding with production adjustments.

The comparative analysis suggests aluminum may be more vulnerable to correction than copper if inventory dynamics normalize, but likely more resilient than steel due to ongoing production cost pressures and trade disruptions.
