Middle East Tensions Drive Sharp Surge in Asia PE Prices

Polyethylene (PE) prices in Asia surged sharply at the start of March as escalating geopolitical tensions in the Middle East triggered concerns over supply disruptions, rising crude oil costs, and increasing freight rates. The market reacted quickly to the rapidly changing situation, with buyers anticipating tighter supply and higher production costs across the petrochemical chain.

On February 28, the United States and Israel reportedly launched a large-scale coordinated strike against Iran, resulting in the death of Iran's Supreme Leader Ayatollah Ali Khamenei. Iran responded by firing missiles at neighboring Middle Eastern countries hosting U.S. military bases, significantly heightening regional tensions.

Amid this geopolitical escalation, Asian PE markets opened sharply higher on March 2. According to ICIS price data, the import price of linear low-density polyethylene (LLDPE) delivered to China jumped 13% compared with the previous working day, reaching $890 per tonne. During the same period, domestic low-density polyethylene (LDPE) prices in China rose by 7% in yuan terms.

Market participants widely expect PE prices to rise significantly throughout March. However, the premium of product prices over raw material costs, as well as price spreads between different PE grades, will depend heavily on how geopolitical tensions evolve and on the supply-demand dynamics within individual markets.

While spot PE prices reacted immediately to the escalation involving Iran, analysts believe that price trends among regions and product grades will diverge further as March progresses. The Southeast Asian market may experience a stronger impact than China due to its higher sensitivity to raw material costs, greater dependence on imported supply, and more direct transmission of freight and insurance costs into product pricing.

China's market, by contrast, may experience slightly less immediate volatility. Stronger domestic supply and inventory buffers could help mitigate some of the rapid price increases despite sustained cost pressures.

Among different PE grades, LDPE is expected to be the most sensitive to the current geopolitical situation. Global supply of LDPE remains relatively tight, substitution options are limited, and supply disruptions can quickly lead to scarcity-driven pricing. As a result, although all PE grades face upward price pressure, price gaps between different products may widen further. If supply disruptions in the Middle East persist, LDPE is likely to outperform LLDPE and high-density polyethylene (HDPE) in the market.

Systemic Risk of Middle East PE Supply Disruptions

Iran is the second-largest polyethylene producer in the Middle East and plays a crucial role in the global PE market. During the conflict, risks to Iranian production facilities and the suspension of operations at the Port of Bandar Abbas could significantly disrupt Iranian PE exports.

Even if the conflict ends quickly — assuming military tensions between the United States and Iran ease within one month — ongoing political instability in the region may keep buyers cautious about sourcing Iranian material in the short term.

Iran is one of China's key PE suppliers. In 2025, imports from Iran accounted for 16% of China's total PE imports. The impact on LDPE could be particularly significant, as Iran is one of the largest Middle Eastern suppliers of LDPE to China. In 2025, Iranian LDPE shipments represented 26% of China's total LDPE imports.

The potential closure of the Strait of Hormuz would further amplify the impact of Middle East tensions on Asian PE markets. As a critical transport corridor linking Middle Eastern energy and chemical exports with Eurasian markets, any disruption to shipping through the strait would significantly reduce regional supply availability. Several global shipping companies have already instructed their vessels to avoid passing through the Strait of Hormuz due to security concerns.

Rising Feedstock Costs Intensify Supply Pressure

In Asia, continued increases in feedstock prices combined with limited upstream supply could further constrain PE production.

The Middle East remains a key supplier of crude oil and naphtha to China. Restrictions on shipping through the Strait of Hormuz increase the risk of energy supply disruptions from the region. Once existing feedstock inventories at Chinese steam crackers are depleted, maintaining stable operations could become challenging. Some producers are already considering lowering operating rates to maintain flexibility in case the situation deteriorates.

Olefin and PE producers in South Korea and Japan face similar challenges. Customs data from 2025 show that Middle Eastern naphtha accounted for more than 70% of Japan's imports and over 60% of South Korea's imports. Rapid increases in crude oil, naphtha, and LPG prices are expected to significantly compress margins for Asian crackers relying on these feedstocks.

'Average operating rates of steam crackers in Asia outside China fell to 75% in February, down three percentage points from January,' said ICIS senior analyst He Xiaoyang. 'With rising risks of production cuts or shutdowns, we expect cracker operating rates to decline further in March.'

However, producers with access to non-Middle Eastern feedstock sources may find opportunities to increase operating rates if rising PE prices offset higher raw material costs.

Chinese coal-based PE producers could benefit most from the current high oil price environment. Coal-to-chemicals facilities may gain a stronger competitive advantage and potentially run at full capacity.

China's Domestic Supply Growth May Not Offset Import Losses

China's polyethylene capacity expanded significantly during the country's 14th Five-Year Plan period (2021–2025). By the end of 2025, effective capacity had increased by 71% compared with 2020, reaching 36.9 million tonnes.

Despite this expansion, China's dependence on PE imports remains around 30%. For LDPE, the import dependence ratio reached approximately 50% in 2025.

In 2026, China is expected to add about 3.73 million tonnes of new PE capacity. However, most new projects are scheduled to start operations in the second half of the year.

As a result, domestic supply growth is unlikely to fully offset reduced imports, particularly because nearly half of China's PE imports originate from the Middle East. With Middle Eastern LDPE supply potentially disrupted and prices rising rapidly, some Chinese producers operating flexible LDPE/EVA units may adjust production plans to prioritize LDPE in order to capture higher market margins.

Global Polyethylene Trade Flows Likely to Reshape

Disruptions to Middle Eastern supply are expected to reshape global PE trade flows in the short term.

If the regional conflict lasts more than a month, demand for U.S. PE cargoes is likely to increase despite longer shipping times and higher overall costs. Buyers may turn to alternative suppliers to secure material amid tightening availability.

For LDPE in particular, capacity expansions in Southeast Asia combined with rising domestic output in China could help partially offset supply shortages in the global market. However, the extent to which these additional supplies can stabilize prices will largely depend on the duration of geopolitical tensions and the scale of disruptions to Middle Eastern exports.
