Styrene is an aromatic monomer produced from benzene and ethylene through ethylbenzene dehydrogenation, used as the primary raw material for polystyrene, ABS resin, and styrene-butadiene rubber manufacturing. Benzene and ethylene feedstock costs, and polystyrene and ABS demand all feed into the price.
Global styrene prices in Q2 2026 stood at USD 1,320 per MT in the United States, the highest among tracked markets, USD 1,265 per MT in India, USD 1,210 per MT in South Korea, and USD 1,175 per MT in China, the most competitively priced tracked market. The United States held the highest tracked price on elevated domestic benzene and ethylene feedstock costs, while China benefited from ample regional production capacity. Steady polystyrene, ABS, SBR, and unsaturated polyester resin demand continued to underpin consumption across all tracked regions, with plant outages and Gulf shipping conditions remaining key swing factors.
Styrene prices held close to Q2 2026 levels through August 2026, tracking regional benzene and ethylene feedstock cost differentials, as steady polystyrene and ABS resin demand continued to support the market across all tracked regions.
The Styrene market should ease gradually through H2 2026 as the Gulf shipping routes reopen and the units that ran at reduced rates during Q2's wave of unplanned outages and scheduled maintenance come back online. The firm polystyrene and ABS demand across Asia should keep a floor under the market even as the feedstock and operational stories both fade into the background. Because H1 2026 squeezed feedstock costs and unit availability at the same time, a full reversal is not the likeliest path; the retreat should be measured rather than sudden.
Two things could reopen Q2's cost pressure: a renewed Gulf shipping disruption, or another round of unplanned styrene unit outages. Head the other way, though, and a faster than expected return of idled capacity, paired with softer polystyrene and ABS restocking, could pull prices below the forecast range.
| Region | 2026 Price Range (USD/MT) | Outlook |
| Global Average | 1,150 - 1,240 | Easing from the Q2 peak as shipping risk unwinds and idled units restart |
| China | 1,110 - 1,195 | Large domestic capacity keeps a floor under prices as polystyrene demand holds |
| United States | 1,235 - 1,330 | Gulf Coast outage recovery keeps this the priciest market for now |
| South Korea | 1,145 - 1,225 | Integrated producers pass through easing feedstock costs into H2 |
| Saudi Arabia | 1,125 - 1,210 | Netback pricing eases as Gulf loading schedules return to normal |
| India | 1,195 - 1,285 | Recovery lags as import-dependent buyers wait on Gulf cargo flows |
The scheduled maintenance at several domestic units met firmer benzene costs, and the combination took the Chinese prices up about 15.8% in Q2 2026, to close to 1,175 USD/MT from near 1,015 USD/MT in Q1.
Why did the price of Styrene change in Q2 2026 in China?
Benzene, the main feedstock, became more expensive through the quarter, which alone would have lifted prices somewhat. What pushed the increase further was a run of scheduled maintenance turnarounds that trimmed domestic output right as demand stayed firm.
No market moved further than the US this quarter in absolute terms. The unplanned Gulf Coast outages compounded an already firming benzene market, and the prices climbed just above 13.3% to close to 1,320 USD/MT from near 1,165 USD/MT in Q1.
Why did the price of Styrene change in Q2 2026 in the United States?
The unplanned production outages along the Gulf Coast tightened merchant supply sharply. That mattered more than the underlying feedstock move on its own, and steady ABS offtake gave the market little room to absorb the disruption gracefully.
Close to 1,210 USD/MT is where the South Korean prices ended Q2 2026, a climb of about 15.2% from near 1,050 USD/MT in Q1 as the benzene costs firmed and non-Gulf demand strengthened across the region.
Why did the price of Styrene change in Q2 2026 in South Korea?
The firmer benzene raised production costs across integrated complexes. The buyers elsewhere in the region who wanted to avoid Gulf-linked exposure turned increasingly to South Korean suppliers.
The Saudi Arabian prices jumped about 16.6% in Q2 2026, the sharpest move tracked here, as the elevated Gulf freight and insurance costs pushed export netback values up to close to 1,195 USD/MT from near 1,025 USD/MT in Q1.
Why did the price of Styrene change in Q2 2026 in Saudi Arabia?
The shipping disruption around the Gulf raised freight and insurance costs enough to show up directly in export pricing, even for a producer with a natural feedstock advantage.
The disrupted Middle East imports and firm polystyrene demand pushed the Indian prices sharply higher in Q2 2026, up about 15.5% to close to 1,265 USD/MT from near 1,095 USD/MT in Q1.
Why did the price of Styrene change in Q2 2026 in India?
A large share of India's contracted Middle East supply failed to arrive on schedule, pushing buyers toward costlier Northeast Asian cargoes at short notice.
The early Gulf shipping tension and post-holiday restocking lifted benzene and styrene costs together, taking the Chinese prices up about 7.4% to close to 1,015 USD/MT in Q1 2026 from near 945 USD/MT in Q4 2025.
Why did the price of Styrene change in Q1 2026 in China?
The rising Gulf tensions from January onward lifted crude and benzene costs broadly. The post-holiday polystyrene restocking added demand-side support on top, setting up the market for the sharper move that followed in Q2.
Close to 1,165 USD/MT is where the US prices settled in Q1 2026, up about 6.9% from near 1,090 USD/MT in Q4 2025 as firmer benzene costs and steady ABS and polystyrene demand pulled the market back from Q4 softness.
Why did the price of Styrene change in Q1 2026 in the United States?
There was no single dramatic trigger here, more a normalisation after a soft fourth quarter.
The South Korean prices rose about 7.7% in Q1 2026, supported by firmer benzene costs and steady regional export demand, to close to 1,050 USD/MT from near 975 USD/MT in Q4 2025.
Why did the price of Styrene change in Q1 2026 in South Korea?
Firmer benzene raised integrated production costs, while regional offtake held steady rather than accelerating. A fairly unremarkable quarter, on the whole.
The cargo availability out of the Gulf tightened well before the Q2 disruption peak, and the Saudi Arabian prices rose about 7.9% in Q1 2026 to close to 1,025 USD/MT from near 950 USD/MT in Q4 2025.
Why did the price of Styrene change in Q1 2026 in Saudi Arabia?
The cargo availability out of the Gulf tightened even before the shipping disruption turned acute, lifting netback values early.
India did not wait for the worst of it. The early Middle East supply concerns and firm polystyrene demand pushed buyers to secure cargoes early, lifting prices about 7.9% to close to 1,095 USD/MT from near 1,015 USD/MT in Q4 2025.
Why did the price of Styrene change in Q1 2026 in India?
The buyers who read the early Gulf warning signs correctly began forward-securing supply, a decision that proved well timed once the sharper Q2 increase followed.
The Styrene market eased through the second half of 2025 on softer benzene costs and cautious downstream restocking, then reversed hard once the Gulf shipping disruption and a wave of unplanned unit outages hit in 2026. The global average fell from near 1,075 USD/MT in Q2 2025 to about 1,005 USD/MT by Q4, then rebounded to close to 1,085 USD/MT in Q1 2026 and about 1,245 USD/MT in Q2. As we can see, the net gain across the window comes to roughly 15.8%, despite the earlier decline.
| Quarter | Price (USD/MT) | QoQ Change | Direction |
| Q2 2026 | 1,245 | +14.7% | ↑ Rising |
| Q1 2026 | 1,085 | +8.0% | ↑ Rising |
| Q4 2025 | 1,005 | -3.4% | ↓ Falling |
| Q3 2025 | 1,040 | -3.3% | ↓ Falling |
| Q2 2025 | 1,075 | - | - Stable |
| Q3 2026 | In Progress | - | - In Progress |
The year 2025 saw prices ease as softer benzene costs and cautious polymer restocking outweighed early-year firmness. The global average opened near 1,050 USD/MT in Q1 and fell to about 1,005 USD/MT by Q4, a decline of roughly 4.3% driven mostly by measured polystyrene and ABS sector restocking through most of the year.
The Chinese prices eased from near 980 USD/MT in Q1 2025 to about 945 USD/MT by Q4, down close to 3.6%, as softer benzene costs and measured polystyrene restocking weighed on the market.
No market fell further than the US in 2025, down roughly 5.2% from near 1,150 USD/MT in Q1 to about 1,090 USD/MT by Q4 as softer benzene costs met cautious ABS sector restocking.
The South Korean prices eased from near 1,020 USD/MT in Q1 2025 to about 975 USD/MT by Q4, down close to 4.4%, on softer feedstock costs and measured regional export demand.
From near 990 USD/MT down to about 950 USD/MT: that was Saudi Arabia's year, a decline of roughly 4.0% as ample regional supply met softer Asian import demand.
The discounted Northeast Asian imports and measured polystyrene demand weighed on the Indian prices all year, which eased close to 4.2% from near 1,060 USD/MT in Q1 2025 to about 1,015 USD/MT by Q4.

It is mostly polystyrene, acrylonitrile butadiene styrene, and styrene-butadiene rubber production that accounts for most global demand. The unsaturated polyester resins used for construction and marine uses make up the rest.
The Q2 2026 average was close to 1,175 USD/MT in China, about 1,320 USD/MT in the United States, near 1,210 USD/MT in South Korea, roughly 1,195 USD/MT in Saudi Arabia, and close to 1,265 USD/MT in India. The Gulf Coast outage recovery keeps the US the priciest market.
The global average rose from about 1,005 USD/MT at the end of 2025 to near 1,085 USD/MT in Q1 2026, then to close to 1,245 USD/MT by Q2, a combined first-half gain of roughly 23.9%.
Early Gulf shipping tension lifted benzene feedstock costs, while post-holiday polystyrene and ABS restocking added demand-side support ahead of the sharper move in Q2.
Somewhere near the 1,150-1,240 USD/MT range is a reasonable expectation, with an easing likely as the shipping risk unwinds and the idled production units return to normal operation.
The US sits highest on Gulf Coast outage recovery and firm ABS demand, while China sits lowest on its large domestic capacity. South Korea, Saudi Arabia, and India fall in between.

Benzene and ethylene feedstock costs, production unit operating rates, and polystyrene and ABS demand cycles drive most movement, with unplanned outages able to amplify swings sharply, as 2026 has shown.
China, the United States, South Korea, and Saudi Arabia hold the largest capacity, while India remains a significant net importer exposed to any disruption in Gulf trade flows.
Quarterly trends help time polystyrene and ABS contract negotiations, while benzene costs serve as an early floor signal for building forward coverage ahead of anticipated unit outages or Gulf disruption.
