The EPDM Rubber Price Trend in Q2 2026 has been shaped by a combination of geopolitical tensions, feedstock shortages, higher energy costs, and supply chain disruptions. EPDM rubber prices moved higher across several important markets during the quarter, particularly during April and May, as disruptions around the Middle East and the Strait of Hormuz affected the movement of naphtha and other important raw materials. By June, the market began showing signs of stabilisation as geopolitical concerns eased and feedstock flows gradually improved. However, prices remained relatively firm in most markets because supply conditions were still tighter than normal.

EPDM Rubber Price Trend in Q2 2026

The second quarter of 2026 was a good example of how developments outside the rubber industry can quickly influence the cost of industrial materials.

EPDM rubber depends on important petrochemical feedstocks, including ethylene and propylene. These materials are closely connected to crude oil, naphtha, energy costs, and refinery operations. When the supply of these feedstocks becomes restricted, manufacturers generally face higher production costs. That pressure can eventually move through the supply chain and affect EPDM Rubber Prices.

During the beginning of Q2, geopolitical tensions in the Middle East created concerns around the movement of naphtha through important trade routes. The situation around the Strait of Hormuz added another layer of uncertainty. At the same time, crude oil values moved higher, increasing feedstock and energy-related costs.

As a result, the global EPDM market started the quarter on a stronger note. The EPDM Rubber Price Chart reflected this upward movement during the first two months of Q2.

However, the market story changed somewhat toward June. Geopolitical concerns began to ease, feedstock availability improved, and supply conditions slowly became more manageable. This did not mean that prices immediately returned to earlier levels. Instead, the market moved toward stabilisation, with some regions recording small corrections while others continued to see modest increases.

South Korea EPDM Rubber Prices

South Korea recorded an increase of around 27% in Q2 2026. The market was affected by restricted naphtha availability and disruptions in the supply chain.

The availability of ethylene and propylene became an important factor for EPDM production. With feedstock availability under pressure, manufacturing costs increased. Production constraints also affected material availability, which made the domestic market tighter.

EPDM prices remained firm during most of the quarter. In June, prices increased by around 1%, showing that supply pressure had not completely disappeared. Although conditions improved gradually, feedstock costs remained supportive.

The South Korean market was also important for other Asian markets because restricted production and export availability affected the flow of EPDM material to countries such as China and Thailand.

USA EPDM Price Trend

The US market recorded an increase of around 18% during Q2 2026.

At the beginning of the quarter, disruptions around the Strait of Hormuz created concerns about feedstock availability. Higher crude oil and energy costs also increased the expenses associated with ethylene and propylene production.

For EPDM manufacturers, higher upstream costs generally mean higher production costs. When these pressures occur alongside tighter material availability, sellers have greater support for maintaining higher prices.

EPDM prices in the US remained firm through much of Q2. However, June brought a small change in direction. Prices corrected by around 2% as feedstock costs eased slightly and supply conditions improved.

This June correction is an important part of the EPDM Rubber Price Index story for Q2 because it indicates that the strongest cost pressures were beginning to moderate.

Netherlands EPDM Price Trend

The Netherlands recorded one of the strongest increases during the quarter, with the EPDM price trend rising by around 28% in Q2 2026.

European markets faced pressure from higher energy costs and concerns about feedstock availability. Middle East-related disruptions affected energy and raw material flows, while low gas storage levels added to the cost pressure in the region.

Higher gas and crude-related costs increased the overall cost of producing EPDM. At the same time, limited availability of ethylene and propylene created additional pressure on the supply side.

Prices remained strong during the quarter, although the situation became more stable toward June. EPDM prices in the Netherlands increased by around 2% in June, suggesting that the market was still tight even as broader supply conditions started improving.

Japan EPDM Price Trend

Japan also recorded an increase of around 28% during Q2 2026.

The main pressure came from restricted feedstock availability and supply chain disruptions linked to the Middle East situation. Reduced naphtha flows affected the availability of important raw materials such as ethylene and propylene.

For buyers, this created a difficult market environment because production costs were rising while the availability of material was becoming less predictable.

EPDM prices remained firm throughout the quarter. In June, prices increased by around 1%, indicating that supply constraints and feedstock costs continued to provide support.

China EPDM Price Trend

China recorded an increase of around 28% in Q2 2026.

Unlike a market that depends mainly on domestic production, the Chinese EPDM market was also affected by supply disruptions from South Korea. Since South Korea is an important source of EPDM material for the Chinese market, production and shipment constraints had a direct effect on availability.

Restricted naphtha flows affected the production of ethylene and propylene, which increased manufacturing costs in the supply chain. Lower availability of EPDM shipments then added further pressure in China.

As a result, EPDM prices remained firm during Q2. In June, prices increased by around 1%, showing that the market had not yet fully relaxed despite gradual improvements in supply conditions.

India EPDM Price Trend

India recorded the largest increase among the markets covered, at around 30% in Q2 2026.

The Indian market was affected by restricted material inflows from Asia as disruptions around the Strait of Hormuz affected feedstock and supply chains. Limited naphtha availability put pressure on the production of ethylene and propylene, while reduced material availability made competition among buyers stronger.

When buyers compete for limited material, prices can remain firm even if demand itself has not changed dramatically. This was an important factor behind the increase in EPDM Rubber Prices in India during Q2.

By June, the market showed some relief. EPDM prices corrected by around 1% as feedstock availability improved and supply pressures gradually eased.

Thailand EPDM Price Trend

Thailand recorded an increase of around 27% during Q2 2026.

The market was affected by restricted EPDM supply from South Korea. Feedstock availability concerns, higher manufacturing costs, and disruptions in export volumes combined to create tighter market conditions.

With fewer materials available for shipment, buyers faced increased competition for supply. This supported higher EPDM prices throughout much of the quarter.

In June, prices increased by around 1%. The continued increase showed that supply limitations had not completely disappeared, even though broader market conditions were starting to stabilise.

What the EPDM Rubber Price Chart Shows

Looking across the Q2 2026 markets, the EPDM Rubber Price Chart shows a clear common pattern.

Prices moved higher during the early part of the quarter as geopolitical tensions, higher crude oil values, restricted naphtha flows, and higher production costs came together.

The increases were different from one market to another:

• South Korea: around 27%
• USA: around 18%
• Netherlands: around 28%
• Japan: around 28%
• China: around 28%
• India: around 30%
• Thailand: around 27%

India recorded the strongest increase among these markets, while the USA recorded the lowest increase.

The differences highlight how local supply conditions, import dependence, energy costs, and regional supply chains can influence the final EPDM price.

EPDM Rubber Price Index and June Market Movement

The EPDM Rubber Price Index for Q2 2026 reflects a market that moved sharply upward before beginning to stabilise.

June was particularly important because several markets showed either smaller increases or corrections. The USA recorded a 2% correction, while India recorded a 1% correction. South Korea, Japan, China, and Thailand each recorded increases of around 1%, while the Netherlands increased by around 2%.

This mixed movement suggests that the market was moving away from the sharp upward pressure seen earlier in the quarter.

Still, stabilisation should not be confused with a complete return to normal conditions. Feedstock costs remained supported in several markets, and supply limitations continued to influence pricing.

EPDM Rubber Price Forecast: What Could Happen Next?

Based on the Q2 2026 market situation, the near-term EPDM Rubber Price Forecast points toward a more balanced market compared with the strong price increases seen during the early part of the quarter.

The biggest factor to watch is feedstock availability. If naphtha, ethylene, and propylene flows continue to improve, production conditions could become more comfortable and price pressure could gradually reduce.

Geopolitical developments will also remain important. Any renewed disruption to major energy or shipping routes could quickly increase feedstock and transportation costs again.

On the other hand, continued improvement in supply chains could limit further price increases and encourage greater market stability.

Therefore, the most reasonable outlook from the Q2 information is not necessarily a sharp fall in EPDM prices, but rather a market that could remain firm while gradually becoming more stable.

The EPDM Rubber Price Trend in Q2 2026 clearly demonstrates how closely the rubber market is connected to the wider petrochemical and energy supply chain. Geopolitical tensions, disruptions around the Strait of Hormuz, restricted naphtha flows, higher crude oil values, and limited availability of ethylene and propylene all contributed to higher prices during the quarter.

Among the markets covered, India recorded the strongest Q2 increase at around 30%, followed by the Netherlands, Japan, and China at around 28%. South Korea and Thailand increased by around 27%, while the USA recorded an increase of around 18%.

June brought some signs of relief, with selected markets showing small corrections while others continued to rise modestly. This indicates that the market was gradually moving toward stabilisation, although supply and feedstock costs remained important price-supporting factors.

For buyers, manufacturers, traders, and other market participants, the main lesson from Q2 2026 is simple: EPDM Rubber Prices can change quickly when energy, feedstock availability, and international supply routes are disrupted. Monitoring the EPDM Rubber Price Chart and EPDM Rubber Price Index alongside feedstock and geopolitical developments can therefore provide a better understanding of where the market may be heading next.
