Lead: Recently, crude oil and pure benzene prices have weakened in tandem, dragging down caprolactam and downstream PA6 market prices. However, tight caprolactam supply has effectively limited the decline, while PA6 chips have seen more pronounced price drops due to ample supply and the off-season for end-use consumption. The current supply chain is characterized by a structural mismatch—tight caprolactam supply versus loose PA6 supply—with cost fluctuations and supply-demand contradictions intertwined, keeping market dynamics in a state of tug-of-war.
In 2026, crude oil prices have continued to fluctuate widely, with geopolitical uncertainties leading to frequent volatility on the cost side of the supply chain. As of August 6, WTI stood at $77.29/barrel, down 8.72% from July 31; Brent was at $82.49/barrel, down 8.47% from July 31. The decline in crude oil prices exerted bearish pressure on pure benzene, which followed the weakening trend. This week, Sinopec cut its pure benzene listed price twice, for a cumulative reduction of 550 yuan/ton to 7,350 yuan/ton. Against the backdrop of synchronized declines in upstream crude oil and pure benzene prices, the bearish cost signals have transmitted downstream, pulling down prices of most products in the caprolactam supply chain.
Given the high uncertainty and frequent wide fluctuations in upstream product prices, cost factors have had a significant impact on caprolactam and downstream product prices. Recently, under the bearish influence of falling pure benzene prices, caprolactam prices have also declined accordingly. However, as the caprolactam industry continues to implement anti-involution production reduction strategies, the overall operating rate across the sector has remained below 70% recently. The overall caprolactam supply pattern in 2026 remains tight, which has somewhat limited the scope of price declines. This week, spot supply of caprolactam has remained persistently tight, with limited spot availability across all regions. Despite falling raw material prices, caprolactam has shown a narrower decline. As of now, spot caprolactam prices in the East China market have dropped to 11,800 yuan/ton on an acceptance-payment, delivered basis.
The downstream PA6 segment remains under sustained pressure. Although PA6 polymerization operating rates are currently at a historic low of only around 60%, the large total production capacity base and the dispersed distribution of producers mean that even with individual enterprises running at low rates, the overall industry supply has not declined significantly. This has kept PA6 chip supply in a persistently loose state, while at the same time supporting rigid demand for caprolactam as feedstock. As a result, the market is experiencing tight caprolactam supply but loose PA6 chip supply, with competitive pressure in the PA6 chip segment remaining high. Meanwhile, the end-use sector is in its consumption off-season, and with raw material prices falling, downstream sentiment has turned bearish. Chip purchasing slowed this week, and PA6 chip prices continued their downward trend with even larger declines. As of now, regular spinning PA6 chips in the East China market are priced at 12,000–12,100 yuan/ton on a cash-payment, delivered basis, while high-speed spinning PA6 chips are around 12,600 yuan/ton on an acceptance-payment, delivered basis.
Looking ahead, cost factors will remain the core driver of supply chain pricing. With geopolitical uncertainties persisting, crude oil and pure benzene prices remain susceptible to news-driven fluctuations, and caprolactam and PA6 prices will continue to move in line with pure benzene trends. On the supply-demand front, the tight caprolactam supply pattern is expected to persist. Lunan Chemical's planned maintenance shutdown at the end of August will further reduce spot supply, providing support for caprolactam prices. However, persistently weak end-use demand, fierce competition in the PA6 chip market, and the narrow spread between PA6 chips and caprolactam mean polymerization enterprises face the dual pressure of "tight feedstock supply and difficult product sales," and further operating rate cuts cannot be ruled out. In summary, with cost volatility coexisting alongside supply-demand mismatch, the tug-of-war between supply and demand in the caprolactam market is set to continue.
