China PP starts week firmly as crude spike, tight supply outweigh constrained demand

China’s PP markets moved in mixed directions over the past few weeks, with bullish and bearish forces repeatedly changing the course of prices even within the same week. Sharp daily and intraday swings in crude oil futures, fueled by an unstable geopolitical environment in the Middle East, kept cost expectations highly volatile, while weak off-season demand continued to cap the upside.

With supply broadly supported by low inventories and ongoing maintenance, sellers adopted divergent pricing strategies, ranging from discounts to stimulate buying to firmer offers aimed at passing through elevated costs.

So far this week, however, stronger cost support and tighter availability have gained the upper hand, pushing the market toward a firmer stance despite lackluster demand.

Crude gains keep the floor firm

Upstream cost pressure has strengthened considerably this week as geopolitical developments in the Middle East sent crude oil futures sharply higher. Brent crude oil futures settled above $87/bbl on Tuesday, August 10, up nearly 11% from the same-day settlement a week earlier and remained around this level during intraday trading on August 11. Despite the pronounced volatility in crude, CFR China spot propylene prices have shown a more measured response, remaining broadly at the same level for the past two weeks and so far this week, according to the ChemOrbis Price Index.

Meanwhile, September PP futures on the Dalian Commodity Exchange took the lead of the crude oil, gaining CNY199/ton ($29/ton) in the first two days of the week although weekly comparison points to a softening.

The combination of higher crude oil and supported feedstock costs has strengthened the cost floor for PP, giving producers greater incentive to resist aggressive discounts. A trader said that domestic and import PP prices rose this week on the back of firmer crude and futures, while logistics disruptions caused by the typhoon and temporary production shutdowns added to supply-side boost. However, another trader highlighted that feedstock prices remained “unusually high for the season,” squeezing downstream margins and reducing buyers’ enthusiasm.

In the meantime, market players have increasingly focused on potential disruptions to energy flows, particularly amid heightened concerns surrounding the Strait of Hormuz. As one producer source confirmed, “Tensions involving the Strait, Yemen and Saudi Arabia, alongside the lack of an agreement between the US and Iran, have continued to complicate the picture.”

Tight availability meets sporadic buying interest

Supply-side conditions have provided an important counterweight to weak demand. The temporary shutdown of the Phase 2 unit at Ningbo Donghua Energy, a slight increase in PP maintenance activity and typhoon-related disruptions have restricted availability in some areas, while further plant shutdowns are expected to temporarily reduce output. A trader also remarked the market was receiving additional support from “low inventory levels across the industry chain,” while a producer source noted that maintenance remained concentrated nationwide, keeping industry operating rates low and availability for certain grades tight. These factors have allowed spot prices to remain relatively firm even as buyers continue to purchase mainly on a need basis.

Demand, however, remains the key obstacle to a sustained rally. Several players said downstream factories have yet to increase operating rates significantly, with inventories still not fully digested and active restocking largely absent despite the approaching Golden September peak season. An end-product manufacturer complained “we have yet to see any signs of demand recovery,” while another manufacturer similarly reported no meaningful improvement in end-user consumption.

Still, selected downstream sectors have shown slight improvement, and with cost support intact and supply relatively tight, one trader expects the market to remain firm with narrow fluctuations; overall, the conflicting forces suggest that China’s PP market may continue to fluctuate within a narrow range rather than establish a clear directional trend in the near term.
