SE Asia PP, PE, PVC rally slows after breakneck surge as affordability limits bite

Southeast Asia’s PP, PE, and PVC markets are showing early signs that the breakneck rally seen in recent weeks is beginning to lose momentum. While prices remain elevated, early-week activity suggests that aggressive hikes are no longer gaining the same traction as downstream resistance strengthens across key markets such as Vietnam, Indonesia, and Malaysia.

Buyers, many of whom built inventories during earlier phases of the rally, are increasingly pushing back against fresh increases, citing weak margins in finished products. At the same time, persistent supply constraints and feedstock uncertainties continue to prevent any meaningful correction. The result is a market that remains tight and elevated, but where the pace of increases is clearly slowing after the extraordinary jumps seen over the past two weeks.

Cost pulse slows after a breakneck rally

After two weeks of relentless increases, upstream olefin markets are showing signs of consolidation, offering a potential breather for downstream polymers. CFR China spot ethylene is currently holding at $1300/ton, following a massive cumulative surge of $590/ton over the previous two weeks. Meanwhile, CFR Southeast Asia ethylene posted a $120/ton increase at the start of this week—still upward, but significantly less aggressive than earlier sharp spikes.

Similarly, CFR China and FOB Korea propylene prices have flattened in early-week trading after recording total gains of $320/ton, pointing to a pause in the rapid cost escalation cycle.

Market participants are closely watching this shift. The slowdown in feedstock increases is being interpreted as an early signal that polymer markets may also begin to stabilize, especially after producers aggressively passed on earlier cost surges.

Meanwhile, this relative stability has been largely driven by a daily decline in crude oil prices as some ships passed through the Strait of Hormuz, although intra-day movements continue to signal a strong underlying uptrend. Still, players are now even more focused on crude’s movements, especially after Iran’s declaration of letting ships and tankers, which do not belong to the US, Israel, and their allies, slip through the SoH.

War-driven surge pushed polymers to extraordinary highs

Before the current slowdown in momentum, Southeast Asia’s polymer markets had already experienced an extraordinary rally triggered by the Middle East conflict and severe logistics disruptions around the Strait of Hormuz.

Compared with the week immediately preceding the outbreak of the war, prices had surged dramatically by last week. CIF Southeast Asia LDPE film climbed by roughly 37%, HDPE film by 32%, and LLDPE film by 36%. Other polymers posted similarly steep increases, with PVC K67 up 38%, homo-PP raffia rising 40%, and PP block copolymer injection gaining about 33% over the same period.

These massive gains help explain why further hikes are now encountering stronger resistance from downstream sectors, even though underlying supply and cost pressures remain firmly in place.

“Too high to sustain”: Buyers push back

Across the region, player sentiment this week reflects a market struggling to reconcile high prices with downstream realities. Early-week trading (Monday-Tuesday) has been largely stable, with several participants noting that recent hikes are noticeably smaller than last week’s jumps.

A Malaysian PE trader described the current environment as a “seller’s market,” driven by earlier cost surges, adding that he is offering slightly above a major domestic producer’s levels to test buyer reactions. However, he also warned that “sudden price increases may lead to a quick collapse later,” highlighting growing caution even among sellers. Another Malaysian trader characterized the situation more bluntly as “quite messy,” after receiving higher offers from a key domestic producer.

In Vietnam, the disconnect between resin prices and downstream affordability is becoming more pronounced. A converter noted that “local polyolefin prices are too high,” explaining that buyers quickly cancel earlier orders if lower offers emerge—creating a wide gap between high and low-end prices. Despite relatively healthy end-product demand, margins remain squeezed as end-product prices couldn’t increase as fast as feedstocks.

Inventory cushion strengthens wait-and-see stance

Another Vietnamese converter emphasized that most buyers are reluctant to engage at current levels, especially since many are holding one to two months of inventory. This has reinforced a widespread “wait-and-see” sentiment, with some warning that if the gap between feedstock and finished product prices persists, downstream production cuts or shutdowns may follow. “CIF offers for PP, PE, and PVC are mostly from China and the US this week and prices are very high. We find it risky to replenish now,” remarked the converter.

Elsewhere, supply concerns continue to complicate the picture. An Indonesian trader noted that a major domestic producer has yet to release its weekly offers. “Quotations are for the materials of a major Malaysian producer and they are very high,” added the trader. In the Philippines, offers have reportedly spiked again amid feedstock rallies and force majeure declarations, though many sellers are still withholding quotations.

PVC markets are similarly firm but uncertain. Indonesian and Philippine players reported sharply rising sell indications, while a Vietnamese trader pointed to a wide price range and said he is waiting for a major Taiwanese producer’s April pricing—though many expect that producer may skip offers to Asia altogether. Meanwhile, a Chinese PVC trader reported implementing increases of $195-220/ton on offers to Southeast Asia.

Overall, the market tone has somewhat shifted early this week. Prices remain high, but resistance is building, inventories are cushioning immediate demand, and buyers are becoming increasingly selective. The rally has not reversed—but its momentum is clearly fading, opening the door for stabilization and the possible disappearance of extreme price ranges in the near term.
