Where is CPL market heading after the price correction?

Key Takeaways

- CPL spot prices fell 1,100yuan/mt (8.5%) since 8 April. Drivers: crude oil correction + selective downstream resistance.

- Demand is not uniformly weak. Commodity chips face margin pressure, but exports, DTY, engineering plastics and films remain resilient.

- Active destocking has pushed downstream inventories to historically low levels. This creates a trigger: any supply cut could spark a sharp rebound.

- CPL operating rates are already restrained–producers have maintained discipline since Q4 2025. Expect precautionary production cuts after Labor Day, driven by high benzene costs and June supply risks.

- Outlook: Near-term softness limited. Substantive supply cuts will trigger a rapid rebound. Downstream buyers face material shortage risks in May–June.

I. Diverging demand pulls CPL lower

The above chart shows that both CPL and nylon 6 prices declined since Apr 8, but with CPL spot falling slightly more than chip.

CPL RMB spot dropped more than 1,100 yuan/mt (8.5%) since 8 April. By month-end, prices were testing 12,300 yuan/mt–a clear correction. Price bargains were unusually tense. Sellers waited early week. Bargaining intensified mid-week. Deals only closed on Friday. This reflects both rising market tension and hesitation on direction.

Macro driver: The CPL/PA6 correction mirrors broader chemicals. The March oil rally built mid?downstream inventories. Then sentiment cooled. High prices + murky geopolitics (US?Iran) made buyers cautious. The inventory digestion shifted pressure to suppliers. Prices fell broadly.

Micro driver: The downward pressure came from downstream. Some chip factories encountered difficulties in sales. In particular, the prices of integrated CS chip plants continued to fall, and since the week before last they had been promoting sales at levels below CPL prices, creating a serious price inversion. This put enormous operational pressure on the main CPL buyer group - single polymerization plants. Consequently, during last week's price negotiations, downstream buyers strongly resisted CPL offers around 13,000yuan/mt.

The persistent inversion forced some integrated plants to cut polymer production, while leading to a month?on?month increase in CPL merchant sales, which gave downstream buyers greater leverage in price negotiations. In addition, with the approaching May Day holiday, sellers also took into account the pressure of product delivery during the holiday period, ultimately leading them to relent on prices.

However, demand is not weak across the board; some segments still show considerable resilience.

For example, nylon DTY and chip export markets are active. According to feedback from some chip producers, overseas export orders are being actively inquired about, even outstripping supply.

The operating rates of high?end engineering plastics and films also remain stable at relatively high levels. Although prices have adjusted in line with the market, processing margins are relatively steady and product flows smoothly.

These resilient segments support CPL consumption. But they cannot reverse the trend.

Broader picture: The whole chain is in active destocking. Prices typically stay weak in this phase. CCFGroup tracking shows downstream raw material and product inventories compressed to low levels–some at historical lows. Implication: If prices keep falling and trigger supply cuts, a rebound opportunity will emerge.

II. CPL producers face a test

Since Q4 2025, CPL producers have successfully limited output to support prices. After Lunar New Year, operating rates rose gradually from the 70% baseline. But overall discipline held–due to unit instability and deliberate smoothing. Even during the April weakness, average operating rates stayed restrained.

However, CPL prices continued to fall before the May Day holiday, gradually testing the 12,300yuan/mt level, and the market became increasingly concerned about the huge uncertainty stemming from geopolitical factors - fearing a collapse in oil prices due to US?Iran negotiations.

As a result, most mid?stream and downstream segments (from polymer to downstream) adopted an extremely cautious approach, with a clear and resolute attitude toward active inventory reduction, in both raw material and product.

Pressure shifted to the supply side: In mid?late April, crude was still high. But facing inventory build, the chain "blinked first". Sellers began difficult active destocking via production cuts and price cuts.

III. The dilemma under high raw material costs: how will CPL producers respond?

In the above chart, CPL plant operating rate is already at year-to-date low levels. Facing the sharp decline in CPL-benzene spread, CPL makers were in difficult choice.

Benzene has no near?term systemic downside. The strait remains closed. US?Iran talks are widely seen as "theatrical delay". For the US, the closure now looks welcome–potentially a tool to harvest global interests. US energy supplier interests are becoming visible.

Result: Benzene is destocking significantly in Q2. Prices remain firmly high. Sulphur is also elevated. Supply security pressure is real.

So why is CPL weak? From a supply?demand view, underlying pressure is not large. The extra CPL volume comes only from a few chip producers cutting polymer–not from broad CPL capacity. Major spot suppliers still hold low inventories. But in a weak sentiment environment, even marginal supply increments set the price direction.

Now the key question: Falling CPL prices + narrowing CPL?benzene spread. CPL producers already run low operating rates. Should they wait for post?holiday sentiment to recover? Or act preemptively?

Two short?term hurdles:

- Material balance is hard to adjust quickly.

- Plant changes right before a holiday face high resistance.

But after Labor Day (1–5 May), the situation may change. Given the foreseeable challenges in ensuring material supply in June, it is not impossible for CPL producers to follow the trend and implement precautionary production cuts. After all, faced with persistently high raw material prices, continuing to operate at current loads would entail greater cost pressure.

IV. Outlook: watch for a rebound and shortage risks triggered by production cuts

In summary, the current CPL market is in a stage where "active destocking" and "demand divergence" coexist. Short-term pressure may continue. But two key variables argue against a major downside.

1. Supply can contract: Post?holiday precautionary cuts are likely. Current operating rates are low. Raw material costs are high. Producer willingness to cut is rising.

2. Downstream inventories are already low: Many mid?downstream segments have squeezed raw material and finished product stocks to historical lows. If CPL cuts further while buyers enter restocking (May–June), shortages will emerge. The rebound could be faster and larger than expected.

View and risks:

- Short term (1–2 weeks): CPL remains under mild pressure. But downside is limited–historically low inventories and firm benzene provide a floor.

- Once post?holiday supply cuts materialize (likely by mid-May): CPL will bottom and rebound. The upside could be sharp given the destocked chain.

- For downstream buyers: The current extreme destocking strategy is risky. Reassess now. Building modest safety stocks in early May is prudent. Over the next two months, "no material to buy" is a real risk.
