The global Styrene Butadiene Rubber (SBR) market moved higher during the second quarter of 2026. The increase was mainly connected with tighter supply, higher raw material costs, and difficulties in moving products and feedstocks through important trade routes. The conflict in the Middle East and disruption around the Strait of Hormuz created uncertainty for producers, traders, and buyers. As a result, many market participants became more careful about securing material.

SBR is widely used in tires, automotive components, and different industrial rubber products. Because these industries require regular supplies, demand remained fairly steady during the quarter. At the same time, the availability of important feedstocks such as styrene and butadiene became more difficult in some markets. This combination of steady demand and tighter supply created upward pressure on the market.

Crude oil costs also played an important role. Higher crude oil prices during the beginning of Q2 increased the cost of several petrochemical raw materials. Producers had to manage these higher expenses while also dealing with increased freight and insurance costs. The situation supported higher selling offers during April and May.

Toward the end of the quarter, the market started to calm. The easing of geopolitical tensions and the reopening of the Strait of Hormuz helped improve shipping conditions. Feedstock availability also began to recover. These developments reduced some of the pressure seen earlier in the quarter and resulted in corrections in June.

Supply Conditions Remain Tight During the First Half of Q2

The first two months of Q2 were particularly strong for the SBR market. Supply concerns became an important factor as disruptions around the Strait of Hormuz affected international trade flows.

South Korean material was particularly important in this situation. Disruptions to supply from South Korea reduced the availability of SBR and related feedstocks for some overseas buyers. With fewer cargoes available, buyers had to compete for material or consider alternative supply sources.

Freight costs added another challenge. Shipping through uncertain routes became more expensive, while marine insurance costs also increased because of geopolitical risks. These additional expenses increased the overall cost of imported SBR.

For buyers, the market became more difficult to manage. Companies that needed regular supplies could not simply wait for prices to fall because production requirements continued. Some buyers therefore purchased material earlier to avoid the possibility of further supply shortages.

This type of cautious procurement supported the market and allowed producers to maintain firmer offers during the strongest part of the quarter.

Feedstock Costs Add Further Pressure

The cost of raw materials was another major factor behind the Q2 increase. SBR production depends on styrene and butadiene, so changes in the availability and cost of these feedstocks can have a direct effect on production economics.

During the early part of Q2, crude oil prices moved sharply higher. This increased the cost base across the petrochemical sector. Producers were therefore dealing with more expensive inputs at a time when supply conditions were already becoming tighter.

Butadiene availability was also affected by changes in naphtha supply. This was especially important for the Indian market, where restrictions affecting South Korean naphtha flows reduced the availability of material needed for butadiene production.

The combination of higher crude costs and tighter feedstock availability created a strong cost-based reason for SBR suppliers to increase their offers.

The US Market Rises by Around 28%

The US SBR market recorded an increase of approximately 28% during Q2 2026.

The market faced supply pressure at the beginning of the quarter because shipments from South Korea were disrupted. This reduced the availability of imported SBR and created uncertainty among buyers.

Higher sea freight and marine insurance costs made the situation more difficult. Importers had to consider not only the supplier's price but also the additional expenses involved in bringing material into the country.

Despite higher costs, demand remained steady from industries using synthetic rubber. Buyers continued to procure material for their regular requirements, helping keep the market firm.

The Styrene Butadiene Rubber (SBR) Price Trend during the quarter therefore remained strongly upward through April and May, supported by limited supply and higher replacement costs.

US Market Corrects in June

Conditions improved during June. The late-Q2 ceasefire and reopening of the Strait of Hormuz helped reduce some of the uncertainty surrounding international shipments.

Crude oil and feedstock costs also began to soften. At the same time, South Korean supply and logistics conditions improved, giving US buyers better access to material.

With supply becoming more comfortable, buyers had less reason to purchase aggressively. The earlier urgency to secure cargoes began to disappear.

As a result, the US market recorded a correction of around 8% in June.

This decline did not completely remove the gains made earlier in the quarter. Instead, it indicated that the market was moving away from the extreme supply pressure seen during April and May.

India Records a Stronger Increase

India experienced an even sharper movement during Q2 2026. The domestic market increased by more than 55% during the quarter.

Several factors contributed to this significant rise. Higher crude oil costs pushed feedstock values upward, while restrictions on South Korean naphtha exports affected India's supply situation.

Lower naphtha availability placed pressure on butadiene production. With less feedstock available, domestic SBR production faced additional limitations.

Import costs also became more important. The Indian rupee reached a record low during the period, making imported material more expensive. Since India relies on imports to supplement domestic availability, currency weakness added to the overall replacement cost.

This created a difficult environment for buyers. Domestic suppliers had to consider the higher cost of replacing their stocks, while buyers had to pay more to secure available material.

Demand Keeps the Indian Market Firm

The Indian SBR market also benefited from steady demand. Tire manufacturing and automotive industries remained important consumers during the quarter.

SBR is commonly used in tire production, so regular requirements from the tire sector can provide a stable base for consumption. Other automotive and industrial rubber applications also contributed to demand.

Even as prices moved higher, manufacturers still needed material to continue their production schedules. This meant that purchasing did not stop completely.

The combination of steady demand, restricted supply, higher import costs, and expensive feedstocks kept the Indian market firm through most of Q2.

June Brings a Correction in India

The situation changed somewhat during June. Feedstock availability began improving, and supply pressure became less severe.

Better material flows reduced some of the concerns that had affected buyers earlier in the quarter. International logistics also improved as conditions around major shipping routes became more stable.

The Indian market consequently corrected by approximately 13% in June.

The decline was significant but remained much smaller than the increase recorded over the full quarter. Therefore, the market continued to sit at an elevated level compared with the beginning of Q2.

The correction also showed that buyers were becoming more cautious. After purchasing additional material during the period of supply uncertainty, some companies were able to reduce their immediate procurement requirements.

Freight Costs Influence International Markets

Transportation costs were an important part of the Q2 story. SBR is traded internationally, so shipping expenses can have a noticeable impact on the final cost paid by buyers.

When freight rates rise, imported material becomes more expensive even if the basic producer quotation does not change significantly. Marine insurance costs can also increase when shipping risks become higher.

This was particularly important for buyers sourcing material from South Korea. Disrupted trade routes increased the cost and complexity of moving cargo.

As shipping conditions improved toward the end of the quarter, some of these additional expenses began easing. This contributed to the price corrections seen in June.

What Could Influence the Market Ahead

The SBR market in the coming months will depend on how supply and demand develop after the Q2 disruption.

If shipping routes continue operating normally and feedstock availability improves, suppliers may face less cost pressure. This could encourage further price corrections or a period of stabilization.

However, the market remains sensitive to crude oil and petrochemical feedstock movements. Any fresh disruption affecting styrene, butadiene, naphtha, or international shipping could quickly increase production and replacement costs again.

India will also remain sensitive to currency movements because imported material plays an important role in the domestic supply chain. A weaker rupee could increase import costs even if international market conditions remain relatively stable.

Conclusion

Q2 2026 was a strong quarter for the global SBR market. The combination of geopolitical uncertainty, restricted feedstock availability, higher crude oil costs, expensive freight, and steady downstream demand pushed the market significantly higher.

The US market increased by around 28%, while India's domestic market rose by more than 55%. Both markets then experienced corrections in June as supply conditions improved and international logistics became easier.

The key issue for the next period will be whether the improvement in supply continues. If feedstock and shipping conditions remain stable, the market could move toward greater balance. However, renewed supply disruptions could quickly bring back upward pressure.

For buyers, producers, and traders, monitoring feedstock availability, crude oil costs, freight conditions, currency movements, and demand from the tire and automotive industries will remain important. Styrene Butadiene Rubber (SBR) Prices are likely to remain sensitive to these factors as the market moves into the second half of 2026.
