- Global caustic soda prices showed a mixed trend in Q1’26, with weakness in early January followed by recovery toward the end of the quarter.
- Feedstock and energy costs remained a key driver, with geopolitical tensions increasing production and transportation expenses.
- Downstream demand stayed moderate, with alumina and chemical sectors purchasing mainly on a need basis, limiting stronger price gains.
Asia
In Asia, the caustic soda price graph remained relatively stable with mild upward movement by the end of the quarter. In China, the prices were ~0.69 RMB/kg (Spot, 32% Lye) in January and ~0.69 RMB/kg in March, with caustic soda prices increasing by ~0.69%. Prices declined in January due to ample supply and weak downstream demand, especially from alumina buyers, who procured cautiously. However, post-holiday restocking and lower-than-expected inventories supported a recovery in February. By March, geopolitical tensions in the Middle East and disruptions in the Strait of Hormuz tightened global energy supply, raising production costs and supporting prices. Trade flows showed China exported significantly higher volumes while imports declined, indicating strong overseas demand support. In India, the prices were ~35.14 INR/kg (Spot, 48% lye) in January and ~36.42 INR/kg in March, reflecting an increase of ~1.66%. The Indian market followed a similar pattern, with initial softness due to balanced supply and demand, followed by gradual recovery supported by rising global costs and improved downstream procurement. On the other developments, Indian Peroxide Limited announced a 400 TPD chlor-alkali (caustic soda) plant at Dahej, Gujarat, expandable to 800 TPD, with Nuberg EPC as contractor; the project targets October 2026 commissioning and integration with hydrogen peroxide operations.
Europe
In Europe, caustic soda prices showed a stronger upward movement compared to Asia. The prices were ~0.30 GBP/kg (CIF, Felixstowe) in January and ~0.39 GBP/kg in March, with prices increasing by ~27.50%. The increase was driven by rising energy costs and supply tightening linked to geopolitical tensions. Disruptions in shipping through the Strait of Hormuz increased freight costs and constrained imports, while energy-intensive chlor-alkali production faced cost pressure. Steady downstream demand allowed these higher costs to pass through to prices.
North America
In North America, caustic soda prices largely resembled the Chinese trend, with relatively stable pricing and limited overall movement. The market was influenced by balanced supply-demand conditions early in the quarter, followed by cost-side pressure from rising energy prices and geopolitical tensions. Global logistics challenges and higher transportation costs supported prices toward the end of the quarter, while steady downstream demand maintained overall market stability.
