## I. Overview of Market Price Dynamics

| Date | Source | Core Content |
|------|--------|--------------|
| 2026-11-04 | SunSirs | Published benchmark price for vinyl ethylbenzene, generating transaction guidance prices based on price big data and pricing models. |
| 2026-11-05 | SunSirs | Same as above; continued updates to the benchmark price system. |
| 2026-11-06 | SunSirs | Same as above; ongoing tracking of price dynamics. |
| 2026-11-09 | SunSirs | Same as above; weekly price updates. |
| 2026-11-10 | SunSirs | Same as above; continuation of price dynamics. |
| 2026-11-11 | SunSirs | Same as above; release of the latest price quote. |

**Key Findings**: Over the past month, SunSirs has released daily price dynamics for vinyl ethylbenzene on six consecutive trading days. However, the disclosed content for each day consists solely of an explanation of the benchmark price calculation framework (including elements such as adjustment coefficient K and premium/discount C), **without directly disclosing specific transaction price figures**. This indicates that the market is in a phase of high information frequency but limited price transparency, necessitating cross-verification with other channels.

## II. Market References for Related Products

1. **Ethylbenzene (Upstream Raw Material) Market**
- **Shandong Market** (as of September 28): Limited corporate sellable volumes; spot supply and demand are in a stalemate; sporadic small-lot indicative selling prices are approximately **9,150 CNY/ton** (delivered), with actual transactions subject to specific negotiation.
- **Lianyungang, Jiangsu**: Satellite Chemical’s 600,000-ton/year ethylbenzene unit is undergoing maintenance and shutdown; inventory levels are moderate; quoted price is **10,600 CNY/ton**.
- The North China market shows sluggish trading activity, with prices generally following the market trend.

2. **Styrene (Downstream Key Product) Market**
- Asian styrene USD market conditions continue to be updated as of October 26. As the largest downstream product of vinyl ethylbenzene, its price fluctuations directly influence demand-side expectations.

## III. Market Analysis and Assessment

**(1) Supply Side: Tight Structure Persists**
- Frequent maintenance of ethylbenzene units (e.g., the shutdown of the 600,000-ton/year unit in Lianyungang) has contracted upstream raw material supply, providing cost support for vinyl ethylbenzene.
- The high-frequency release of price dynamics by SunSirs reflects extremely high price sensitivity among market participants and intense supply-side competition.

**(2) Demand Side: Driven by Essential Needs, Limited Elasticity**
- Although the downstream styrene industry has expectations of new capacity release, purchases during the concentrated maintenance period are primarily for essential needs, with low enthusiasm for inquiries.
- No significant signs of demand expansion have been observed; overall market trading remains sluggish.

**(3) Price Logic: Cost-Driven Volatility**
- Vinyl ethylbenzene prices are primarily anchored to the cost line of ethylbenzene plus ethylene. Currently, the price differential between Shandong and Lianyungang for ethylbenzene reaches **1,450 CNY/ton**, indicating significant regional divergence.
- The continuous operation of SunSirs’ benchmark price system indicates that the market pricing mechanism remains dominated by model-based and data-driven approaches. However, the absence of specific numerical values creates a blind spot for short-term directional judgment.

## IV. Forecast and Recommendations

| Dimension | Assessment |
|-----------|------------|
| **Short-term (1-2 weeks)** | With tight supply and flat demand, prices are likely to maintain high-level narrow-range volatility. The estimated range is **10,500-11,200 CNY/ton** (projected based on Lianyungang ethylbenzene quotes and historical volatility). |
| **Medium-term (1-3 months)** | If downstream styrene units restart and demand recovers, coupled with winter cost-side support, prices may rise in a stepped manner; conversely, if raw material prices fall, prices will face downward pressure. |
| **Risk Warnings** | ① Supply recovery after the end of ethylbenzene unit maintenance; ② Fluctuations in international crude oil and ethylene prices; ③ Downstream operating rates falling short of expectations. |

**Operational Recommendations**: Given the high information density but insufficient price transparency, it is recommended to closely monitor specific daily price figures from SunSirs, actual spot transaction orders for ethylbenzene, and the trend of styrene in the USD market. Precise trading decisions should be made only after cross-verifying these three lines of information. Before data becomes fully clear, it is advisable to maintain a wait-and-see stance and proceed with light position probing.
