Bitumen fell 3.45% to ¥4,305/t—the second-largest drop among energy commodities today, trailing only fuel oil (-5.64%). This is not a cost-driven correction: the Brent-WTI spread widened to $5.38/bbl, yet bitumen crack spreads did not follow. It is a classic demand collapse signal. The core driver is seasonality: road construction in China, Korea, and Japan has largely concluded by late October. JODI data shows China’s refinery throughput remains high at 13,247 kb/d—but there is no corresponding absorption capacity downstream. Korea’s refinery throughput is 2,977 kb/d, with total refined product stocks at 70,492 kb—including 16,889 kb of diesel and 4,441 kb of jet fuel—above 3-year averages, signaling sluggish terminal flow. Japan’s lamp oil stocks stand at 20,523 kb, and LNG imports remain unreported; the kerosene-LNG switching window is now operationally open, further diverting heavy distillate demand. As a quintessential heavy-end product, bitumen’s de-stocking logic hinges entirely on road project timelines. With no new infrastructure starts announced and multiple projects in East and North China entering final compaction phases, spot demand has contracted sharply. Singapore’s fuel oil stocks are just 6,327 kb (JODI)—among the region’s lowest—yet this offers negligible price support for bitumen, as it is not a direct substitute. Social inventory drawdown has shifted from ‘active drawdown’ to ‘passive accumulation’: several East China storage terminals report outbound loading rates down >30% MoM (qualitative assessment; no quantitative feed). For SNSUC clients, the import hedging window is open: using ESPO crude pricing and current Brent at $92.07, landed CIF duty-paid cost is ~¥4,120–4,160/t—trading at a ¥185–225/t discount to the front-month contract. Immediate physical procurement carries margin safety. Re-exporters should pause restocking; holders should hedge in ¥4,280–4,300/t bands in tranches.
