1. Report Industry Investment Rating - Unilateral: Neutral; Inter - period: PL01 - 02 inter - period reverse spread; Cross - variety: None [3] 2. Core View - Supply - side overall start - up increased month - on - month, PDH device start - up rate rebounded, some major manufacturers had maintenance plans, and the expected reduction in the market supply supported propylene prices. Downstream start - up showed a mixed trend, with the start - up of phenol - acetone increasing rapidly, and the demand had a small - scale phased support. The cost of propylene decreased as crude oil weakened and propane prices declined. Attention should be paid to the geopolitical situation's impact on the crude oil end [2] 3. Summary by Directory 3.1 Market News and Important Data - Propylene: The closing price of the main propylene contract was 6,491 yuan/ton (+40), the spot price in East China was 6,400 yuan/ton (+75), and in North China was 6,540 yuan/ton (+240). The basis in East China was - 91 yuan/ton (+35), and in North China was 49 yuan/ton (+200). The propylene start - up rate was 74% (+1%), the difference between propylene CFR in China and naphtha CFR in Japan was 200 US dollars/ton (+1), the difference between propylene CFR and 1.2 propane CFR was 96 US dollars/ton (-6), the import profit was - 286 yuan/ton (+0), and the in - plant inventory was 34,420 tons (+830) [1] - Propylene downstream: PP powder start - up rate was 38% (+1.48%), production profit was - 160 yuan/ton (-150); propylene oxide start - up rate was 74% (+1%), production profit was - 271 yuan/ton (-162); n - butanol start - up rate was 89% (-7%), production profit was - 267 yuan/ton (-99); octanol start - up rate was 77% (-1%), production profit was 448 yuan/ton (-172); acrylic acid start - up rate was 79% (-1%), production profit was 406 yuan/ton (-53); acrylonitrile start - up rate was 74% (-2%), production profit was - 625 yuan/ton (-210); phenol - acetone start - up rate was 77% (+4%), production profit was - 672 yuan/ton (+0) [1] 3.2 Market Analysis - Supply side: The overall start - up increased month - on - month, PDH device start - up rate rebounded, some major manufacturers had maintenance plans, and the market supply was expected to tighten [2] - Demand side: Downstream start - up showed a mixed trend, the start - up of phenol - acetone increased rapidly, and the demand had a small - scale phased support [2] - Cost side: Crude oil weakened, and the decline in Saudi CP drove down propane prices, leading to a downward shift in propylene cost support [2] 3.3 Strategy - Unilateral: Neutral; Inter - period: PL01 - 02 inter - period reverse spread; Cross - variety: None [3] 3.4 Directory Details - **Propylene basis structure**: Includes figures such as the closing price of the main propylene contract, East China and North China basis, etc. [7][10][12] - **Propylene production profit and start - up rate**: Involves figures like the difference between propylene CFR in China and naphtha CFR in Japan, propylene capacity utilization rate, etc. [17][24][29] - **Propylene import and export profit**: Covers figures such as the difference between South Korea FOB and China CFR, Japan CFR and China CFR, etc. [32][34] - **Propylene downstream profit and start - up rate**: Contains figures like PP powder production profit and start - up rate, propylene oxide production profit and start - up rate, etc. [40][45][50] - **Propylene inventory**: Includes figures of propylene in - plant inventory and PP powder in - plant inventory [67]
