Chemical Industry ETF Penghua rises over 1.3%, with net subscriptions during the trading session expanding to 500 million shares. The previously affected refining and chemical fiber sectors in the industry chain have shown significant rebounds.

The U.S. and Iran reached a ceasefire agreement, with negotiations lasting 2 weeks. Iran opened the Strait of Hormuz for 2 weeks. Oil prices plunged, and major refining and polyester filament products that were affected earlier in the upstream industrial chain rebounded significantly.

In addition, since the Middle East conflict broke out more than a month ago, global key petrochemical bases such as the Jubail Industrial City have been hit. The region’s annual output accounts for 6%-8% of global petrochemical products; damage to facilities and the repair cycle will significantly extend the time for chemical supply recovery. Combined with the restricted transportation through the Strait of Hormuz, the global chemical supply chain is shifting from being driven by “demand concerns” to being dominated by “supply instability.” For multiple industrial chains such as pure benzene, butadiene, and PDH, plant turnarounds have already been reduced or production has been suspended. The disruption strength and duration on the supply side are both greater than what was expected in the earlier period.

Guotai Junan Securities said that, based on the current situation, the Strait of Hormuz, because of its special geographic location, still effectively controls the key energy and materials supply chains. However, as the increase in energy prices gradually takes effect and translates into tighter supply, the impact from the industry chain alliance has begun to extend to inventory risk, the supply restoration cycle, and the spread of planting cycles, as well as the investment cycle, and so on. Due to restrictions on oil and gas supply and transportation, production facilities in multiple locations have clearly shown reduced startup rates or shutdowns one after another. Refining industry chain products such as pure benzene and butadiene, as well as PDH production facilities, are all facing supply and startup adjustments. This forms multi-dimensional supply adjustments across industrial chains such as the nylon industry chain, polyurethane industry chain, and polyolefin industry chain. Even if strait transportation is restored, facility restart adjustments and the return of inventories occur, and damaged facilities are gradually repaired, the resulting extended impacts will continue. Therefore, the impact on the chemical supply side is higher than expected.
