Core Viewpoint - The styrene market has experienced a significant price surge, with East China spot prices exceeding 8000 yuan per ton, driven by macroeconomic improvements and supply constraints, but the sustainability of this increase is questioned due to weak cost support and rising resistance from downstream sectors [1][2]. Supply Dynamics - The recent price increase in styrene is attributed to a recovery from previous overly pessimistic market sentiments, bolstered by unexpected progress in US-China trade talks and a rebound in international oil prices, leading to a notable increase in buying interest [2]. - Supply remains tight in major production areas such as East China, Shandong, Hebei, and Northeast China, which supports market sentiment and reduces the risk of significant price drops [3]. Cost Support - The price of pure benzene, a key upstream raw material for styrene, has fluctuated between 6000 and 6300 yuan, with a recent increase of nearly 500 yuan following improvements in international conditions [4]. - Despite a recent rebound, the momentum in the pure benzene market is expected to slow, leading to a narrow trading range, which may weaken its impact on downstream products [4]. Downstream Resistance - The surge in styrene prices has created challenges for downstream industries such as EPS, ABS, and PS, which are struggling with squeezed profits and rising costs [5][6]. - Downstream companies are exhibiting reduced willingness to purchase high-priced styrene due to increased financial pressure, despite potential benefits from improved US-China trade relations [5][6].
