Multiple Drivers: Polyester Bottle Flakes Market Sees a Strong Surge This Week

March 13th News

This week (March 9-13), the polyester bottle chip market in China experienced a strong rally, with the largest single-day price increase reaching 13%, and the cumulative weekly price increase approaching 30%. The intensity and rapid pace of the market movements caught all parties by surprise. Currently, PET bottle chips are in a complex situation driven by multiple factors — high crude oil prices providing support, major manufacturers reducing production to tighten supply, and steady demand release during the traditional peak season. These three forces, rarely aligned, have simultaneously pushed the market into a typical structural upward trend, characterized by "upstream raw material shortages forcing prices up and downstream players following passively." As of March 13, according to price data, the mainstream average price of polyester bottle chips in East China was 8,965 CNY per ton.

I. Cost Side (the most critical reason)

• Geopolitical "black swan" triggers a cost bomb, crude oil/PX/PTA/MEG soar across the board in China

The near-disruption of the Strait of Hormuz has served as the “spark” and core cost driver behind this round of market volatility. This is no ordinary oil price fluctuation—it’s a “supply crisis” in which 20% of the world’s oil supply faces the risk of disruption, and the resulting surge in costs is both rigid and dramatic.

The latest data show that the spot price of WTI crude oil is currently $92.70 per barrel, with a price increase exceeding 6%. This cost hurricane originating at the source is rapidly spreading downstream along the industrial chain, indicating that cost pressures are swiftly being passed on to downstream sectors.

• The processing fee for bottle chip factories has been severely squeezed, leaving them no choice but to follow the price increases and halt sales to protect their profits.

II. Supply Side (Driving a Sharp Rise)

• The bottle chip operating rate is low (about 66-68%), with a significant drop in production in February compared to the previous month. Spot inventory is low, and there are few low-priced goods in China.

•Several major factories in China have halted sales and continuously adjusted prices, further tightening the supply of goods in the market.

•Red ocean freight cost surges, export quotations increase, and both domestic and international markets rise in tandem.

Revised for clarity: •Red ocean freight costs have surged, leading to an increase in export quotations, with both the Chinese and international markets experiencing a synchronized rise.

III. Demand and Emotions (Amplifying Price Increase)

• The peak season for beverages and packaging has kicked off, with stable essential demand and strong buying sentiment. Downstream buyers are rushing to place orders and stock up.

The traditional peak season for stocking up on beverage ingredients, which begins in March, has provided a certain level of demand support and time buffer to absorb the current high prices. The existence of strong seasonal demand has temporarily increased downstream industries’ tolerance for price hikes, giving midstream traders the confidence to “buy at higher prices,” thus creating a short-term positive feedback loop. According to price data, the price of water bottle flakes in East China has surged from 7,030 CNY/ton on March 6 to 7,800 CNY/ton on March 11, and is now approaching 9,000 CNY/ton today—a staggering week-on-week price increase. Such a substantial price hike has been made possible precisely within the context of the peak season, partly confirming the supportive role of seasonal demand. Currently, we are in the midst of the traditional March procurement peak season, during which downstream beverage manufacturers are stockpiling ingredients in preparation for the upcoming summer consumption boom, thereby providing a solid demand base for the elevated prices.

•Futures capital pushed up the prices, leading to a daily limit-up and consecutive surges, which in turn boosted the sentiment in the physical market.

Future Market Prediction

In the short term (1-2 weeks), before the crude oil situation becomes clear and the tightness in spot supply eases, PET bottle chip prices will remain strong, with a higher likelihood of increases than decreases. However, high prices have already accumulated significant risk.

Mid-term (late March–April): Be wary of a rally followed by a pullback.

• Risk point:

◦ Crude oil/raw material prices have fallen, weakening cost support.

◦ Bottle flake facilities restart (Sanfangxiang, China Resources, etc.), supply recovers

◦High downstream prices lead to resistance, with rigid demand weakening and the enthusiasm for price chasing cooling down.

• Trend: If raw materials weaken, there is a high probability that bottle chips will retreat from their high levels and undergo consolidation.
