There is a special variety in the futures market that we may come into contact with in our daily life, but we don't know much about PTA. There are many factors that affect the price of this futures product. Let's have a look. 1 polyester PTA is mainly used to produce polyester. Production of 1 ton PET requires 0.85-0.86 ton PTA. The development of polyester industry determines the consumption demand of PTA. Among polyester products, polyester has the largest demand for PTA, which determines the consumption of PTA. Polyester is the main raw material of textile industry. In other words, the prosperity and development of textile industry directly affects the consumption of polyester market, and then determines the demand for PTA. 3 The source of oil price PTA is oil. The rise of oil brings costs to the downstream, which directly leads to the increase of PX cost, thus affecting PTA production cost and finally PTA price. Investors should pay attention to oil prices when participating in PTA futures. 4 raw material price PX is the most direct and important raw material for PTA production. More than 90% of PX in the world is used to produce PTA. The price of PTA is largely controlled by raw material PX, especially when the price of PTA is quite close to the cost or even upside down, the force of raw material price is very obvious. 5 cotton price The downstream product of PTA is polyester, which is the raw material for textiles with cotton. The two are an alternative relationship. The price relationship between them will affect their consumption in textile ingredients, thus affecting the demand for PTA. Finally, the supply and demand lever will affect the maintenance of PTA.6 devices at home and abroad. PTA production equipment needs to be overhauled once a year. PTA production enterprises will choose off-season or bad months to arrange equipment maintenance, so as to reduce market risks and have an impact on market supply. 7 RMB exchange rate changes China is the largest textile producer and exporter in the world. The appreciation of RMB reduces the export competitiveness of textiles, and the textile market situation will in turn directly affect the development of chemical fiber industry and upstream PTA industry. Summary: PTA futures prices are greatly influenced by its upstream and downstream products, and its upstream and downstream products in the industrial chain indirectly affect PTA prices through supply and demand leverage. The factors that affect the price are: polyester development, polyester development, oil price, raw material price, cotton price, equipment maintenance at home and abroad and the change of RMB exchange rate.
