Global petrochemical markets are rapidly tightening as escalating tensions in the Middle East disrupt key supply chains, pushing the sector out of a prolonged glut and into a sudden deficit. The impact is already visible across core products: ethylene and propylene markets are coming under pressure as supply from major producing hubs weakens, with China and Saudi Arabia – two of the world’s largest players – both facing constraints.
Around 13% of global ethylene capacity and roughly 20% of methanol production are currently offline due to their exposure to the conflict zone, highlighting the scale of disruption. If the Strait of Hormuz remains blocked through the end of April, the market could lose up to 20-25 million tons of ethylene, along with significant volumes of paraxylene and ethylene glycol. Saudi Arabia has already begun curbing feedstock production and downstream output, while China – heavily reliant on Middle Eastern supplies of naphtha, condensate and methanol – is grappling with tightening feedstock availability.
The pressure is being compounded by domestic policy decisions in China. Refiners have been instructed to prioritize fuel production to stabilize gasoline and diesel prices, reducing naphtha output – a key input for steam cracking. At the same time, domestic LPG prices have surged to a 12-year high, further increasing costs for petrochemical producers.
Prices across the value chain have moved sharply higher. Naphtha in Singapore climbed to around $1,000 per ton by the end of March from roughly $780 earlier in the month, while ethylene and polyethylene prices have roughly doubled. Freight rates have also increased amid higher bunker fuel costs, adding another layer of pressure on margins.
The speed of the shift has been striking. Only recently, the petrochemical sector had been weighed down by structural oversupply, driven by large-scale capacity additions in Asia and the Middle East. That surplus has now effectively disappeared under the strain of geopolitical disruption.
Looking ahead, the market is likely to face sustained shortages of polyethylene and polypropylene, with downstream industries such as construction, packaging and automotive manufacturing expected to feel the impact. At the same time, persistently high feedstock costs are eroding margins: with naphtha prices near $1,000 per ton, cracking spreads have turned negative, raising the risk of shutdowns among smaller Asian producers and accelerating consolidation in favor of larger, integrated players.
China’s methanol-to-olefins (MTO) sector is also under pressure. Many plants rely on Iranian methanol and are now being forced to either seek alternative supplies or reduce operating rates, further tightening domestic availability of ethylene and polypropylene.
In response, major Asian economies including China, India, South Korea and Japan are increasing purchases of alternative feedstocks such as ethane, LPG and naphtha from the United States, Canada, Australia, West Africa and Russia. However, these volumes are expected to cover only a fraction of the flows that typically transit through the Strait of Hormuz, suggesting that supply constraints – and elevated prices – may persist in the near term.
