Recently, a sudden escalation of geopolitical conflict in the Middle East drove international oil prices sharply higher, with Brent crude breaching the $90-per-barrel mark once again; chemical product prices also saw significant gains. However, the core reason why chemical prices rose more sharply than crude oil lies in the sector's own robust fundamentals. A "triple resonance" of extremely low inventories, supply contraction, and peak-season expectations amplified the geopolitical risk premium, propelling a broad-based surge in global chemical prices.

Critical Global Inventory Shortages

Low inventory levels have been the key factor amplifying the price surge of chemicals relative to crude oil. According to data from the U.S. Energy Information Administration (EIA), U.S. styrene inventories fell to 315,000 metric tons for the week ending August 22—a 3.7% drop from the previous week and a decline of over 20% year-on-year, marking the lowest level since 2023. Since the second quarter, multiple styrene production units along the U.S. Gulf Coast have operated at reduced rates; strong export demand has prevented effective inventory accumulation, keeping spot market supplies tight.

The situation in the European market is even more severe. Due to the ongoing shutdown of INEOS’s benzene unit in Marl, Germany—triggered by force majeure in early August—European styrene inventories are approximately 25% below the five-year average, leaving very limited supplies available for spot trading. Consultancy data indicates that European benzene inventories are also at historical lows for this time of year, with aromatics stocks in the major storage hubs of Antwerp (Belgium) and Rotterdam (the Netherlands) falling below warning thresholds.

The outlook for the Asian market (excluding China) is equally concerning. Styrene inventories in South Korea’s major petrochemical clusters—Daesan and Yeosu—have dropped to multi-year lows; local producers are prioritizing supplies for contract customers, drastically reducing volumes available to the spot market. Aromatics inventories at facilities operated by Japan’s Idemitsu Kosan and on Singapore’s Jurong Island are also low, maintaining a tight regional supply-demand balance. Low inventory levels imply an extremely tight supply of globally circulating spot goods; any marginal disruption to supply is rapidly reflected in prices—a fundamental reason why the price elasticity of chemical products far exceeds that of crude oil.

Spreading Supply Contractions

Beyond the issue of critically low inventories, the supply side for various global chemical products has also experienced sharp contractions. Butadiene was the standout performer in August; its Asian market price climbed from approximately $1,000 per tonne at the start of the month to over $1,200 per tonne by month's end—a rise of more than 20%. This rally was primarily driven by a wave of scheduled maintenance at Asian production facilities. Major South Korean producers—including YNCC, Lotte Chemical, and LG Chem—successively declared force majeure, causing industry operating rates to drop significantly and making spot supplies extremely difficult to source.

The surge in butadiene prices was not an isolated incident. In mid-July, a sudden fire at BP’s Gelsenkirchen refinery in Germany cut off the supply of benzene feedstock; consequently, INEOS Phenol—a leading global producer—declared *force majeure* on its phenol and acetone production. The affected INEOS plant in Gladbeck houses the world’s largest single-line phenol production unit, with annual capacities of 650,000 tonnes for phenol and 400,000 tonnes for acetone. Its shutdown significantly amplified the impact on the European supply chain, forcing downstream customers to scour the global market for supplies.

Even more concerning is the persistent extreme drought in Europe, which has caused water levels in the Rhine River to drop to historic lows. Chemical giants such as BASF, Covestro, Evonik, and INEOS—all of which have extensive production facilities along the Rhine—faced disruptions in the transport of raw materials and finished products. Some companies declared *force majeure* on specific products, while soaring logistics costs further drove up the landed prices of chemical products in Europe.

The convergence of these multiple supply shocks has resulted in a synchronized contraction of the global chemical supply landscape.

Traditional Peak Season Approaches

Market anticipation of the traditional peak consumption season serves as the third driving force behind this market trend. Historically, the period from the end of the third quarter to the beginning of the fourth quarter marks a seasonal peak in global demand for chemical products, as downstream industries—such as coatings, plastics, and synthetic rubber—typically ramp up procurement. With the manufacturing sectors in Europe and the US showing a moderate recovery this year, and the IMF projecting global economic growth of 3.0%, there is a solid foundation supporting peak-season demand, leading to high market expectations for a rebound.

However, expectations for this year's peak season are facing a reality check. High prices are dampening the willingness of end-users to restock, with downstream enterprises preferring to maintain low-inventory strategies.

Analysts generally believe that the current price surge is driven primarily by a contraction in raw material supplies rather than by a pull from end-user demand. In a recent report, Goldman Sachs noted that current chemical prices already fully factor in geopolitical premiums and peak-season expectations; consequently, should geopolitical tensions show signs of easing or end-user demand data fall short of forecasts, the accumulated risk premium could rapidly unwind, potentially leading to a market correction that exceeds expectations.

In summary, the future trajectory of global chemical markets will hinge on the interplay between the evolving situation in the Middle East and the actual strength of peak-season demand. Market divergence is widening, and investors should closely monitor marginal changes on both the supply and demand sides. (Source: China Chemical Industry News)
