Introduction
The global chemical market has seen sharp volatility at the start of 2026. Renewed geopolitical tensions in the Middle East and the sudden escalation of the situation in Iran have directly driven a surge in crude oil prices, known as the “mother of the chemical industry.”
However, for China’s polyvinyl chloride (PVC) market, this external “fire” has collided with a “cold snap” from domestic policy adjustments. Amid the complex interplay of cost support and the removal of export tax rebates, China’s PVC industry stands at a crossroads filled with uncertainty.
The Upside: Geopolitical Conflicts Ignite Cost Support
The recent escalation in Iran has become the biggest variable in the global energy market. As a key member of the Organization of the Petroleum Exporting Countries (OPEC), tensions in Iran have sparked strong fears over potential crude oil supply disruptions.
Crude oil prices surge: International crude oil prices have risen sharply, with both WTI and Brent crude futures hitting multi-period highs. The spike in oil prices has quickly rippled up the chemical industry chain.
Strong cost floor: For ethylene-based PVC produced from petroleum, rising crude prices directly increase production costs, forming a firm bottom for PVC prices. Market sentiment has reacted swiftly: PVC futures have strengthened consecutively, with main contracts rebounding sharply from lows and lifting spot market quotations.
The Downside: Removal of Export Tax Rebates Pressures Long-Term Demand
Just as the market embraced bullish expectations from cost-side support, a policy announcement brought a sobering reality.
Policy takes effect: Starting April 1, 2026, the export tax rebate policy for PVC will be officially abolished. This will add approximately $75 per ton to the cost of China’s PVC exports.
External demand under pressure: Exports have long been a critical channel to absorb domestic PVC capacity and ease domestic demand pressure. The removal of tax rebates will directly weaken the price competitiveness of Chinese PVC products in the global market. Faced with low-cost competitors from the Middle East and the United States, China’s PVC export orders face downside risks, casting a shadow over a domestic market that relies heavily on exports to balance supply and demand.
Current Status: Sentiment in the Short Term, Supply and Demand in the Long Term
Caught between bullish cost-driven forces and bearish policy constraints, China’s PVC market is showing a complex operating trend.
Short-term logic: sentiment leads: For now, uncertainty from geopolitics and high crude oil prices remain the main trading themes. In the near term, PVC prices are expected to stay strong supported by costs and market sentiment. Any developments in the Strait of Hormuz could trigger sharp volatility in futures markets.
Medium-term concerns: high inventories and weak demand: Domestically, fundamentals remain weak. Social PVC inventories are still at high levels for the same period in history, with slow destocking. Meanwhile, the real estate sector — the main downstream industry — has not seen a clear recovery in construction starts and activity, leaving demand unable to provide strong upward momentum.
Long-term variables: policy and situation evolution: The market’s future direction hinges on two key factors:
Geopolitical developments: whether conflicts expand and the actual impact on crude supply, which will determine how long cost support lasts.
Domestic demand: with export headwinds locked in, whether policy stimulus or industry adjustments can unlock new domestic demand will define the medium-term ceiling for PVC prices.
Conclusion
China’s PVC industry is now caught in a “dual world of fire and ice.” The crude oil rally driven by tensions in Iran has acted as a short-term boost, lifting prices; yet the removal of export tax rebates serves as a reality check, urging market participants to face the severity of tightening external demand.
Amid this tug-of-war between bulls and bears, only by looking beyond short-term noise and accurately grasping the fundamentals of supply and demand can market players navigate the coming turbulence steadily.
