Caustic Soda

Caustic Soda Market Dynamics Intelligence, Analysis, and Forecast

I. Market Dynamics Intelligence
(A) Price Trends
- In July 2026, the spot price of caustic soda overall remained weak. On July 1, the reference price stood at RMB 667.00 per ton; by July 27, the benchmark price stabilized at RMB 643.00 per ton—reflecting a downward trend throughout the month, with an overall decline of approximately 3.6% in July.
- The main futures contract price for caustic soda closed at 1,866.0 on July 21; prior to the market holiday on July 24, it opened at 1,878.0, reaching a high of 1,925.0 and a low of 1,875.0—indicating some intraday volatility, yet still remaining within a broadly weak trend.

(B) Supply Situation
- Persistent overcapacity pressure remains. Domestic caustic soda capacity surpassed 53 million tons in 2025, and over 2 million tons of new capacity are scheduled for commissioning in 2026. Although growth has moderated, absolute incremental capacity remains substantial. Annual output is projected to exceed 43 million tons, sustaining a structurally oversupplied market.
- Chlor-alkali co-production intensifies supply pressure. With liquid chlorine prices holding relatively high, chlor-alkali enterprises enjoy attractive profitability, reinforcing their “chlorine-to-compensate-for-alkali” operational strategy. Although integrated chlor-alkali plant profitability has declined somewhat, it remains above the threshold that would trigger widespread proactive production cuts. Since May, the industry has entered its concentrated maintenance period: operating rates dropped to ~81.2%, and weekly output fell to ~800,000 tons—yet current output remains elevated year-on-year.

(C) Demand Situation
- Oxidized aluminum sector demand support weakening. As the largest downstream consumer of caustic soda, the alumina industry saw new capacity additions in 2026; however, constrained by poor profitability, actual operating rates remain around 80%, and new capacity ramp-up has lagged expectations. Purchasing remains strictly demand-driven, with strong downward pricing pressure from buyers.
- Non-alumina demand remains modest. Viscose staple fiber (VSF) operating rates hover around 87%; hardwood pulp operating rates stand at ~70%. While overall operating rates remain acceptable, no concentrated restocking activity has occurred—purchasing continues to be demand-driven, offering insufficient support for caustic soda demand. In the new energy sector, lithium hydroxide operating rates continue recovering, currently at ~46%, contributing modest incremental demand for caustic soda—but this remains inadequate to reverse the broader weak demand trend in the near term.
- Export support shifting from strength to weakness. In March, amid Middle East geopolitical tensions causing overseas plant shutdowns, export expectations for Chinese caustic soda rose. However, actual exports in March were flat month-on-month, failing to show significant growth. As regional tensions eased and overseas facilities gradually resumed operations, global supply increased, eroding China’s competitive edge. New inquiries declined month-on-month in April–May.

(D) Inventory Status
As of mid-May 2026, sampled liquid caustic soda producers’ factory inventories totaled ~572,300 tons—a YoY increase of 47.36%, reaching a multi-year high for this period. Sluggish downstream resumption of operations post–Spring Festival, coupled with weaker-than-expected inventory drawdown during the traditional “Golden March/Silver April” peak season, led to persistently elevated inventories. Despite reduced supply due to maintenance in May, inventories continued rising—notably underscoring sustained high-inventory pressure.

II. Analysis and Judgment
(A) Short-Term Weakness Unlikely to Reverse
The caustic soda market faces multiple headwinds: oversupply, soft demand, and high inventory pressure. In the near term, expectations of new capacity commissioning, limited upside potential in downstream operating rates, and persistent inventory digestion challenges will keep prices under pressure, sustaining a weak trading environment.

(B) Regional Market Divergence
Market performance may vary across regions. For instance, trading activity improved in Inner Mongolia on July 15, whereas Shandong Province experienced repeated downward adjustments to liquid caustic soda quotations throughout July—potentially attributable to local supply-demand imbalances, downstream industrial concentration, and transportation cost differentials.

III. Forecast
(A) Price Trend
We anticipate that the caustic soda market will maintain its oversupplied, capacity-excess structure throughout Q3 2026, with prices oscillating weakly at the bottom range—lacking catalysts for any sustained upward momentum. Should excessively low prices prompt increased maintenance at high-cost facilities, short-term supply tightening could offer temporary price support. Nevertheless, given ongoing new capacity rollouts and persistently sluggish demand, the fundamental oversupply will persist—and the overall price center may drift lower.

(B) Supply-Demand Outlook
On the supply side, newly commissioned capacity will sustain structural oversupply in the near term unless large-scale production cuts or industry consolidation occur. On the demand side, neither the alumina sector, non-alumina sectors, nor export demand are expected to improve significantly in the short run—keeping overall caustic soda demand subdued.

(C) Industry Consolidation
In the longer term, intensifying market competition and stricter environmental regulations may accelerate industry consolidation. Smaller-scale, technologically less advanced producers may exit the market, while larger players expand market share via mergers, acquisitions, and strategic reorganization—thereby enhancing industry concentration, efficiency, and competitiveness.
