Summary of Key Points
In the fall of 2008, prices of polyolefins (such as LLDPE) plummeted by more than 50% within five weeks. However, it weren't the factories that found processing unprofitable that were affected; rather, it was the traders who hoarded inventory and the highly leveraged integrated companies. The collapse was caused by a mismatch between supply and demand (capacity growth far outpaced demand) coupled with the credit crisis triggered by the bankruptcy of Lehman Brothers. The 4 trillion yuan in bailout measures helped prices rebound quickly, but they also sowed the seeds for future overcapacity. Although the industry hasn't seen such a sharp drop since then, a gradual decline can be just as devastating, as both situations are ultimately due to excess supply.
I. A 50% Drop in Five Weeks! How Did Polyolefin Prices Plummet?
In the summer of 2008, polyolefin prices reached record highs: LLDPE at $1,840 per ton at Chinese ports, and crude oil also soared to $147 per barrel. The entire industry was expanding capacity at that time, with no one anticipating a 60% drop in prices just four months later.
The groundwork for the collapse had already been laid:
- Global聚乙烯 production capacity reached its highest level in 26 years (89.3%), leaving little room for flexibility in response to even minor changes in demand.
- Capacity growth outpaced demand by 5.5 percentage points, creating the largest supply-demand gap on record.
Lehman Brothers went bankrupt on September 15th, but polyolefin prices didn't crash immediately. It wasn't until a month later that buyers began to adopt a "wait and see" strategy: if you don't buy today, it will be cheaper tomorrow, so the rational choice seemed to be to never buy at all. Sellers couldn't drive sales by lowering prices and were forced to reduce them week by week. LLDPE prices dropped from $1,275 to $700 within five weeks, with a weekly decline of up to 17.6%, akin to a rollercoaster ride.
II. Counterintuitive! It Wasn't the Processing Plants That Failed, but Those Who Hoarded Inventory and Borrowed Heavy Amounts
You might think that factories with unprofitable processing operations would be the ones to suffer, but the data proves otherwise:
- The processing segment didn't lose money: The production process involves converting crude oil into ethylene (through cracking) and then into polyethylene. Profits in the polymerization phase (the difference between polyethylene and ethylene prices) barely changed, from $395 to $310.
- The real victims were two groups of entities:
- Traders and hoarders: They bought inventory in July, which evaporated by 60% within five weeks. Sinopec suffered a loss of $1.18 billion due to the impairment of its stockpiles, five times more than the previous year's loss.
- Highly leveraged integrated companies: For example, LyondellBasell used $20 billion in leverage for an acquisition, incurring $12 billion in debt. As prices fell, their debts remained unchanged, and the company went bankrupt in 2009 (but later restructured and got rid of its debts, eventually benefiting from the shale gas boom to become a market winner). Dow Chemical borrowed money for the acquisition of Rohm and Haas; however, when the joint venture with Kuwait failed, it had to cut dividends for the first time in 96 years.
III. The 4 Trillion Yuan Bailout Staved Off Immediate Disaster but Created Overcapacity
Prices hit their bottom on November 7, 2008, and the State Council announced ten measures to boost domestic demand on November 5th, followed by the release of a 4 trillion yuan stimulus package on November 9th. The next week, prices rebounded from $700 to $725, an increase of 73% in just seven months. The rapid recovery wasn't due to a surge in demand but rather the return of capital to the market.
Consequences: The bailout prevented the industry from "clearing out" excess capacity, and all the facilities that had been shut down were brought back into operation after 2010. China's true overcapacity in polyolefins didn't begin with the 2008 collapse but rather with the subsequent economic support.
IV. Subsequent Declines: A More Hidden Pain than the 2008 Crash
The decline in 2008 was like a sudden "heart attack" (a 60% drop in five weeks), while later declines were more akin to a chronic illness:
- In April 2020, prices dropped to $650, lower than in 2008, but the decline occurred over two and a half years without being labeled a crisis.
- From 2021 to 2025, prices fell from $1,240 to $740, a 40% decrease, with only a weekly drop of 0.18%. However, the facilities that were shut down never made headlines and didn't return to operation.
Reasons: The supply-demand gap was similar to that in 2008 (capacity growth outpaced demand by 5.1% in 2022, close to the 5.5% in 2008), but the credit environment wasn't as tight, so no one was forced to sell their assets simultaneously. The outcome was the same: excessive capacity remained a problem.
V. Five Lessons Learned from 2008 (In Layman's Terms)
1. Inventory levels are more important than the amount of money invested: In a bull market, holding inventory can be profitable; in a bear market, it's a risk (similar to bonds, where the longer you hold, the more you lose). Traders in 2008 failed not because they bought at high prices but because they held too much for too long.
2. Don't borrow heavily at the peak of a cycle: Facilities can be replaced, and customers can be acquired, but debt is fixed. LyondellBasell's downfall was due to taking on excessive leverage at the peak of the market.
3. Integration isn't always the solution: While it can lead to higher profits during upturns, it exposes more vulnerable parts of the business (such as large inventory and costly cracking processes) during downturns, making the company more vulnerable.
4. Regional price differences can offer opportunities during a collapse: In Asia, prices are quoted weekly, leading to rapid drops; in the Gulf region, contracts are based on monthly prices, resulting in slower declines. You can profit from these differences if you have access to both markets.
5. Bailouts create long-term issues: The 2008 crisis was quickly resolved, but the excess capacity that resulted from the bailout became a persistent problem.
This article highlights that during economic cycles, the most fatal factors are not the sharp price drops themselves but rather excessive inventory accumulation and heavy borrowing. A gradual decline can be just as harmful because it erodes a company's competitiveness over time. 2008 marked the beginning of a new pricing phase for the industry; the ceiling of $1,840 per ton hasn't been reached again in eighteen years.
