1.2.2 Petrochemical Capacity 1.2 Petrochemical business unit 1.2.1 Petrochemical Market Overview Petrochemical market situation in 2023: The demand for petrochemical products continued to be sluggish being affected by several factors. These included the protracted conflict between Russia-Ukraine, along with significant global economic slowdown due to persistent high inflation leading to continuous interest rate hikes by central banks worldwide. China’s economy was obviously seen not recovered as anticipated following intensification of the property crisis. Even though Chinese government issued various economic stimulus measures, the demand remained unrecovered due to lack of purchasing confidence resulting in more cautious spending, especially those in durable goods sector that led to slowdowns in production and export. Nevertheless, with travel restriction eases by several countries, tourism industry continued to recover boosting demand in certain industries such as food packaging as well as health and medical equipment. On the supply side, there was a pressure from new production capacity, especially those in China, Vietnam, and Indonesia entailing excess supply in the region and pulling plastic pellet prices down. Consequently, some producers decided to reduce their utilization to maintain profit margins and market equilibrium.
