The Asian ethylene market has been weakening throughout 2025. The monomer has depreciated from $870/t CFR NEA in January by $125/t to $745/t CFR NEA in December primarily because of growing supply from new start-ups in China and flagging demand. Volatile naphtha quotes have also brought uncertainty to the market as well. Some producers are trying to mitigate losses by cutting their output. South Korean ones are doing so with the government support. Others, such as ExxonMobil in Singapore, intend to close down some crackers in 2026.
