Polystyrene Price Index and Historical Data Trends | IMARC Group

Global Polystyrene Price Trend & Market Outlook – Q2 2026 Polystyrene Price Index & Historical Data indicate that global polystyrene prices recorded a sharp downtrend of approximately 12–14% in July 2026, driven by weak downstream demand and declining styrene monomer costs across key markets. Procurement teams are increasingly leveraging structured intelligence tools such as the Polystyrene Price Data Subscription Service to track real-time pricing benchmarks and optimize sourcing strategies. Across July, Asia-led markets experienced the steepest corrections, while Europe moved counter-trend with price increases due to supply constraints. Insights derived from IMARC Group’s July 2026 price-tracking database and methodology highlight a market under pressure from oversupply conditions, softened packaging demand, and reduced construction activity. The polystyrene price trend reflects a transitional phase where cost-side easing outweighs consumption recovery. Regional Polystyrene Price Snapshot July 2026 Northeast Asia : 1.18 USD/MT (↓ -16.3%) Europe: 62 USD/MT (↑ +8.7%) India: 36 USD/MT (↓ -11.1%) Southeast Asia: 28 USD/MT (↓ -14.7%) South America: 20 USD/MT (↓ -4.8%) The pricing spread highlights a divergent regional pattern , with Europe commanding the highest price due to constrained supply, while Northeast Asia recorded the steepest decline. A gap of over USD 0.4/kg equivalent range reflects differences in feedstock costs, operating rates, and localized demand recovery across global markets. Regional performance in July 2026 shows a clear imbalance between supply and demand. Asia-Pacific markets, including Northeast and Southeast Asia, witnessed significant price corrections due to excess inventory and reduced export orders. India followed a similar trajectory with declining packaging sector demand. In contrast, Europe experienced upward price movement driven by tighter supply and plant operating constraints. South America remained relatively stable, supported by moderate consumption in packaging and consumer goods. Collectively, global markets reflect a demand-driven correction phase, with regional supply dynamics playing a critical role in price differentiation. Regional Polystyrene Price Analysis – Q2 2026 North America (USA) Polystyrene pricing in the USA remained relatively stable with mild downward pressure , aligning with global trends. While specific July pricing is not listed, the region followed a slight decline trajectory due to easing styrene costs and balanced domestic demand. Packaging and construction sectors provided steady consumption, preventing sharper corrections. Asia-Pacific (China, India, Japan) The Asia-Pacific region experienced the most significant price declines , with India at USD 1.36/kg and Northeast Asia at USD 1.18/kg . The trend remained strongly downward , driven by oversupply and reduced export demand. China and Japan also faced similar pressure due to lower downstream consumption and competitive pricing strategies among producers. South America (Brazil) South America, represented by Brazil, recorded prices at USD 1.2/kg , showing a moderate decline of -4.8% . Demand remained relatively stable compared to Asia, supported by local packaging industries. However, lower import costs and global price pressure influenced the regional trend. Supply And Demand Overview – July 2026 Supply conditions in July 2026 were characterized by ample availability of polystyrene across major producing regions , particularly in Asia. Producers maintained high operating rates in anticipation of demand recovery, resulting in inventory accumulation. Feedstock styrene prices declined during the month, further reducing production costs and enabling competitive pricing. On the demand side, consumption remained subdued across key end-use sectors such as packaging, construction, and consumer goods. Asia-Pacific markets experienced weaker export orders, while Europe’s demand remained relatively stable but constrained by...
