Asian Petrochemicals Face Demand Pressure After Oil Price Drop

The easing of tensions between the United States and Iran and growing expectations that the Strait of Hormuz will fully reopen have raised hopes of a recovery in Middle Eastern energy supplies, prompting optimism across Asian petrochemical markets.

Crude oil prices have fallen sharply, easing imported inflation pressures for Asia's energy-importing economies and improving access to petrochemical feedstocks. At first glance, the development appears overwhelmingly positive for the region's chemical sector.

However, the pricing dynamics of the energy and petrochemical industries are far more complex. From a full supply-chain perspective, the transition from geopolitical conflict to industry recovery may not be as straightforward as many expect.

More accurately, the market is shifting from pricing driven by supply fears to pricing determined by weak demand fundamentals. The temporary war premium that supported prices during the conflict did little to alleviate profitability pressures across Asia's petrochemical sector and may ultimately make operating conditions even more difficult.

Industry participants may face four distinct phases in the months ahead.

Phase One: Rapid Disappearance of the War Risk Premium

Following the framework agreement reached between the United States and Iran in mid-June, expectations have grown that navigation through the Strait of Hormuz will gradually normalize. Crude oil prices have already declined significantly, while spot prices for Middle Eastern crude, naphtha and refined petroleum products are expected to move back toward pre-conflict levels.

The Asian naphtha market has even shown instances where forward prices exceed spot prices, while naphtha margins relative to Brent crude have fallen sharply.

These developments indicate that the cost support previously generated by shipping disruptions, supply concerns and panic buying during the conflict is being repriced.

As war-related premiums are removed from crude oil and naphtha markets, upstream cost support weakens substantially. Petrochemical product prices across Asia are therefore likely to adjust downward, bringing profit-margin pressures back to the forefront for producers.

Phase Two: Physical Supply Recovery Will Take Longer Than Price Adjustments

Even if the Strait of Hormuz fully reopens, restoring Middle Eastern oil and gas production, restarting refineries, recalibrating shipping insurance arrangements and rebuilding inventories will require time.

Infrastructure damaged during the conflict — including oilfields, refineries and ports — may take considerably longer to return to pre-war conditions, and some facilities may never fully recover.

Yet commodity markets typically react faster than physical supply chains. Feedstock prices can decline rapidly and transmit through the value chain well before logistics and production systems return to normal.

This creates a period of mismatch in which prices have already fallen while physical supply conditions remain constrained.

For petrochemical producers, simultaneous volatility in both feedstock and product prices makes it difficult to maintain profitability in the short term.

Although this mismatch affects markets globally, its impact is particularly significant for Asia.

During the conflict, cracker operators across the region were forced to reduce operating rates because of feedstock shortages. Surging naphtha prices drove up costs for ethylene, propylene, butadiene, aromatics and their downstream polymer chains.

The key issue is no longer whether feedstock supplies will return. Instead, it is how markets will transition from scarcity-driven pricing to pricing based on actual demand. As supplies normalize, premiums generated by geopolitical risks, panic buying and substitution effects must be removed.

The result is a more challenging market environment: feedstock supplies have yet to fully recover, prices have already fallen sharply and downstream demand remains weak.

Phase Three: Demand Remains the Industry's Core Weakness

China remains both the world's largest producer and consumer of petrochemical products, making it the most important demand variable for the global industry.

Based on current consumption and investment trends, end-user demand appears insufficient to absorb the large volume of new production capacity added in recent years.

As a result, exporting chemical products has become an increasingly necessary strategy for Chinese producers.

While exports may create opportunities for Chinese manufacturers in the short term, they also increase competitive pressure across regional markets by introducing larger volumes of lower-priced products.

Although overseas sales can help absorb excess capacity, they do not necessarily improve profitability. Instead, they may lower the overall pricing benchmark across Asian markets.

Should Middle Eastern chemical production fully recover and return to export markets, competition throughout Asia is likely to intensify further.

Phase Four: Lower Feedstock Costs Do Not Guarantee Higher Margins

From a macroeconomic perspective, lower oil prices benefit net energy-importing economies such as Thailand, the Philippines, India, South Korea and Japan.

These countries experienced rising import costs and inflationary pressures during the conflict. As crude oil prices retreat and supply conditions improve, inflation and import costs are expected to ease.

For the petrochemical sector, however, lower oil prices do not automatically translate into improved profitability.

Demand remains weak, inventories are elevated and buyers continue to expect further price declines.

When feedstock costs fall sharply, product prices often decline first rather than margins widening.

Producers therefore face a situation in which cost support disappears while product prices fall even faster, increasing the likelihood of margin compression.

Compared with the second quarter, when wartime premiums supported pricing, profit margins for many companies could decline significantly during the third quarter following the conflict.

For supply chains already suffering from severe overcapacity, lower oil prices may actually deepen losses, forcing producers to reduce operating rates or temporarily halt production.

For many manufacturers, the greatest concern is not high oil prices themselves, but the risk of uncontrolled declines in product prices once cost support disappears.

Key Indicators to Watch

The end of the conflict should not be viewed as a straightforward positive development for the petrochemical industry. Rather, it represents a broad repricing process across the value chain.

Meaningful improvement will likely require several conditions to occur simultaneously: logistics normalization, inventory reduction, price stabilization and a recovery in end-market demand.

Over the next three to six months, market participants should closely monitor four indicators:

• Whether shipping through the Strait of Hormuz remains consistently stable rather than temporarily restored.

• When Middle Eastern supplies of crude oil, naphtha, methanol and aromatics fully recover.

• Whether Asian petrochemical producers continue reducing operating rates, delaying restarts or shutting down facilities.

• When downstream buyers shift from waiting on the sidelines to actively rebuilding inventories.

The expected end of the conflict has fundamentally altered pricing dynamics across Asia's petrochemical industry.

During the war, markets focused on supply security and the ability to absorb rising costs. In the post-conflict environment, attention is returning to shrinking premiums, recovering supply and underlying supply-demand balances.

Feedstock supply pressures are likely to ease gradually in the coming months, but product prices and industry profit margins may come under increasing pressure.

The end of the conflict is not necessarily a signal of industry recovery. Instead, it marks a return to the structural challenges that existed before the crisis began.
