Seoul: South Korea will ban hoarding of key petrochemical feedstocks starting Wednesday, the government said, as the Iran war raises the risk of supply disruptions. The industry and finance ministries announced in a joint statement Tuesday that they will issue and enforce the ban from midnight. According to Yonhap News Agency, supply disruptions are already starting to hit parts of the petrochemical market, as rising naphtha prices driven by Middle East tensions push up costs, squeeze production, and heighten worries about hoarding. The measure covers seven naphtha-derived base feedstocks - ethylene, propylene, butadiene, benzene, toluene, xylene, and other light oil fractions. Businesses handling these materials will be barred from holding inventories exceeding 80 percent of the levels from the same period last year in the 30 days before an inspection begins. The government said it may expand the restrictions to items derived from the base feedstocks if they are additionally deemed at risk of supply disrup tions. Officials stated that they may also order emergency adjustments to production, shipments, and sales of the affected items if supply concerns persist despite the measures.
