This was because China’s Zero-COVID policy and real estate crisis hampered economic activities affecting petrochemical demand, hence lower demand for Naphtha, a raw material for petrochemical products. Naphtha - Dubai spread in 4Q22 was USD -14.6 per barrel enhancing by 38% from USD -23.4 per barrel in 3Q22. This was owing to rapidly declined crude oil price. In the meantime, Naphtha demand was still pressured by China’s Zero-COVID policy. • ULG95 Spread - Higher: ULG95 - Dubai spread in 2022 was USD 18.8 per barrel increasing by 69% from USD 11.1 per barrel in 2021. The product and crude oil prices fluctuated due to the Russia-Ukraine conflict. Concurrently, Gasoline demand was supported by lockdown eases in several countries throughout the world, while China’s Zero-COVID policy and recession concerns curbed some Gasoline demand in 2H22. ULG95 - Dubai spread in 4Q22 was USD 9.4 per barrel being down by 29% from USD 13.2 per barrel in 3Q22 as Gasoline demand softened seasonally and China’s Zero-COVID policy dampened demand. On the contrary, Gasoline supply increased as Naphtha spread was low, thus more Naphtha blending activities in Gasoline production. 175 Management Discussion and Analysis (MD&A) IRPC PUBLIC COMPANY LIMITED
