The subsidy — not the pump price — is the number to watch. Japan's Agency for Natural Resources and Energy announced on 28 October that the gasoline subsidy for 29 October – 4 November would be ¥52.4/litre, the highest since the scheme launched in 2022 and ¥9.6 above the previous week; the earlier record was ¥51.0 for 17–30 September. The national average retail price of regular gasoline was ¥170.1/litre on 26 October, down ¥0.1 on the week. The subsidy is paid to wholesalers to hold pump prices near ¥170/litre. Adding the two back gives a rough 'unsubsidised cost' reading of around ¥222/litre (170.1 + 52.4, excluding tax structure and distribution margins — a shadow price, not an invoice). In other words: the retail print looks frozen, while the real cost has been pushed up by an entire subsidy step within a year.

Why the subsidy has to keep rising. The agency cited higher crude prices and increased replacement procurement costs. The crude data is unambiguous: on 30 October the NYMEX December contract settled at $104.12/bbl (+$2.12) and Brent December at $117.64/bbl (+$2.76). Japan's crude imports remain heavily Middle East-dependent; with transit constrained, buyers are pushed toward more distant replacement barrels from the US Gulf and West Africa, raising both purchase cost and freight — which is precisely why the monthly replacement-supply adjustment was raised to ¥7.2/litre from 29 October. The subsidy is not conjured out of nothing; it simply parks the increase in international oil and freight costs outside the retail price, with the government carrying the bill.

The phase-out is the real variable. The Japanese government set out on 29 October that from December through the following spring the target pump price will rise ¥5/litre each month and the gasoline subsidy will be gradually withdrawn, while watching crude price trends — alongside subsidies for electricity, gas and water from December to February. This carries three implications. First, price control is shifting from road fuels to power and gas: the burden point in household energy bills moves, which is the other side of the same coin as the record ¥9,738 Tokyo electricity bill we flagged today. Second, a flattened retail price means Japan's current product demand curve is artificial — ¥170 is a policy price, not a market price, and price elasticity will only re-emerge once the subsidy is fully withdrawn next spring. Third, the subsidy breaks the pass-through from retail back to wholesale, quietly compressing refiner and wholesaler margins, which feeds back into refinery run rates and crude purchasing timing — a leading indicator for Japanese crude import volumes.

What it means for SNSUC. Gasoline and diesel are not within our quotable range (hazardous chemicals are excluded across the board), but this data set still has direct value for the categories we can touch. First, when reading Japanese product and energy demand, ignore the retail price and read the two shadow prices instead — the ¥52.4 subsidy and the ¥7.2 replacement-cost adjustment are the marginal price Japan pays to hold pump prices at ¥170, and they reveal the true cost increase far better than the sticker. Second, Japanese industrial buyers are having their energy budgets crowded out by power and gas bills, which lowers tolerance on industrial consumables such as base oils SN150/SN500, lubricants and paraffin wax — a signal of narrowing negotiating room, not of vanishing demand; respond with shorter quote validity, split deliveries, and freight and packaging listed separately. Third, with the phase-out completing next spring, Japanese domestic energy costs will surface in one step; any cross-quarter contract with a Japanese buyer must carry an explicit price-adjustment trigger for subsidy withdrawal, or the supplier absorbs the entire increase.
