On January 8, the CFR Japan price of naphtha was $540.75 per ton, with the ethylene-naphtha processing spread at -$55.75 per ton, a decrease of $18.00 per ton month-on-month. PriceSeek analysis on naphtha, sentiment score: -1. The article indicates that the ethylene-naphtha processing spread decreased by $18 per ton month-on-month to -$55.75 per ton, suggesting that the cost of naphtha as a feedstock for ethylene production has risen relative to ethylene revenue, leading to a deterioration in processing margins. This may result in downstream producers reducing their demand for naphtha procurement, thereby exerting downward pressure on naphtha spot prices. The score is -1 (generally bearish), as the risk of weakening demand is significant, though no extreme supply-demand shifts are involved.

Ethylene, sentiment score: 1. The ethylene-naphtha spread has widened negatively to -$55.75 per ton, with a month-on-month decrease of $18 per ton, reflecting a further deterioration in ethylene production economics and deepening losses. This may prompt producers to reduce output or adjust supply, leading to a contraction in ethylene spot supply and supporting price increases. The score is +1 (generally bullish), as the expectation of reduced supply is favorable, though attention should be paid to whether subsequent changes in demand offset this effect.
