1、 Price trend

According to the monitoring of the commodity market analysis system of Shengyi Society, the PVC spot market fluctuated within the range this week (3.17-21), and the price performance was weak. As of Friday, the average price of SG-5 PVC carbide method in China was 4894 yuan/ton, with a price drop of 0.12% during the week.

2、 Market analysis

This week, PVC’s weak consolidation was the main focus, with some manufacturers lowering their prices by around 50 yuan/ton during the week. The main reason is the lack of favorable fundamentals, resulting in weak performance of crude oil prices and a downturn in the futures market. PVC prices continue to show a weak trend, with a slight downward shift in the overall range. From the perspective of supply and demand fundamentals, the spot PVC market has shown loose supply and demand, and most manufacturers are operating stably. The supply pressure has not changed much, dealers’ offers are generally weak, downstream demand performance is insufficient, downstream procurement is mainly based on spot prices, inquiry and procurement enthusiasm is not high, and the market atmosphere is sluggish. The hanging order price is relatively low. Overall, it is still mainly driven by basic needs, and the trading atmosphere is average. As of now, the quotation range for PVC SG5 electric aggregate in China is mostly around 4800-4900 yuan/ton.

In terms of upstream calcium carbide, since March, the market price of calcium carbide has stabilized and risen narrowly. This week, the price increase was weak, and the price has stabilized.

Supply and demand side: Downstream tire production is basically stable, mainly supporting the demand for natural rubber market. As of March 14th, the operating load of semi steel tires in domestic tire enterprises was around 8.30%; The construction of all steel tires by tire enterprises in Shandong region has slightly increased to around 6.9% of the load.

Market forecast: When domestic and international raw material prices stabilize at a high level, but in the later stage, with the opening of some regions at home and abroad, the price of natural rubber raw materials may continue to fall. The downstream construction is gradually increasing, which provides some essential support for the demand for natural rubber, but the inventory of Tianjiao Port continues to grow slightly; Overall, it is expected that the natural rubber market will weaken and consolidate in the short term.

Future expectations

According to the data analyst of Business Society’s octanol product, downstream demand has rebounded, and the supply of isooctanol has increased, causing the price of isooctanol to rise first and then fall.

Analysis of Market Factors

In terms of supply and demand: During the mid week period, n-butanol factories in Shandong Province actively shipped goods to maintain low inventory, while downstream users stocked up on small orders at low prices, resulting in poor overall demand and slow transmission of n-butanol supply and demand. As the weekend approaches, the atmosphere of low-level inquiries in the market has improved, and the transmission of supply and demand has slightly improved.

Market analysis in the future

At present, there are maintenance plans for some facilities in the n-butanol field in Shandong Province, and there are expectations of a decrease in the supply side, which has improved the market’s support expectations. Downstream demand is stabilizing and recovering. The n-butanol data master of Shengyi Society predicts that in the short term, the domestic n-butanol market will mainly maintain stable operation, and specific changes in supply and demand information need to be closely monitored.
