According to WPB, China’s bitumen futures market surged on the first trading day after the National Day holiday, with the main Shanghai Futures Exchange contract rising by more than 7% during morning trading, even as refinery inventories increased sharply during the market closure. The divergence between futures and physical-market indicators suggests that the October 8 rally reflects a major post-holiday repricing of energy risk rather than clear evidence that China has entered a new immediate physical bitumen shortage.
The Shanghai Futures Exchange had been closed from October 1 through October 7 and officially resumed trading on October 8. Bitumen opened strongly alongside the broader Chinese energy and chemical complex, and by around 9:58 a.m. the main contract had risen approximately 7% to around CNY 5,453 per metric ton. By the morning close, bitumen remained more than 7% higher, while fuel oil had climbed more than 16%, low-sulfur fuel oil more than 9% and domestic crude oil futures nearly 7%.
The synchronized move across fuel oil, crude, LPG, petrochemicals and bitumen is important because it shows that bitumen was part of a broader energy-sector repricing rather than an isolated road-binder rally. Chinese futures had been unable to react during the seven-day National Day closure, leaving multiple days of international energy, shipping and geopolitical developments to be incorporated when domestic trading reopened.
The magnitude of the bitumen move was also facilitated by the wider trading limits in place around the holiday period. SHFE had temporarily set the daily price limit for bitumen futures at ±12% as part of its National Day risk-control arrangements, giving the contract sufficient room to absorb a large reopening adjustment. This technical factor does not explain the direction of the rally, but it is important when interpreting the scale of the first-day move.
The physical market, however, did not reproduce anything close to the same increase. China’s domestic heavy road-bitumen average stood at approximately CNY 6,411 per metric ton at midday on October 8, up only CNY 4 per metric ton, or around 0.1%, from CNY 6,407 before the holiday. Regional prices were mixed rather than uniformly surging, with some southern markets raising quotations while other areas remained unchanged or moved lower.
This divergence provides one of the most important signals in the current market. Futures traders rapidly repriced energy and supply risk after a week-long closure, but refinery gate and regional physical prices did not immediately validate a comparable increase in actual spot scarcity.
Refinery inventory data reinforce that distinction. Chinese bitumen producer inventories reached approximately 420,000 metric tons on October 8, increasing by 45,000 tons from 375,000 tons on September 28. That represents a 12% increase over the holiday period and shows that material accumulated at refineries while normal dispatch activity slowed.
The inventory increase was particularly visible in northeast China, where refinery stocks rose by around 25,000 tons, or 50%. Eastern and southern China each added approximately 17,000 tons. Refiners continued producing during parts of the holiday, while transportation and customer lifting slowed and downstream purchases remained focused largely on immediate requirements, allowing stocks to build.
This does not mean China suddenly has abundant bitumen supply. The same October 8 inventory figure remains around 44.1% below the level recorded a year earlier, demonstrating that the broader 2026 market remains much leaner than normal historical conditions. The correct interpretation is therefore that physical availability improved relative to the end of September, not that the underlying supply constraints of 2026 have disappeared.
Refinery operating data provide further evidence of that distinction. Capacity utilization among 77 Chinese heavy road-bitumen producers fell to approximately 22.2% during October 2–8, down 1.5 percentage points from the previous week and 12.3 percentage points below the comparable level a year earlier. Several refineries stopped bitumen production recently, while others reduced output.
China therefore entered the post-holiday period with an unusual combination of higher refinery inventories and relatively low production utilization. This can occur because inventories are a balance between production and withdrawals rather than a simple measure of refinery operating rates. Even moderate production can create stock accumulation when holiday logistics slow significantly and downstream buyers take only essential volumes.
That distinction is essential when assessing whether the market is genuinely tight. A physical shortage normally becomes more convincing when inventories decline, refinery utilization is restricted, spot availability becomes difficult and physical prices rise together. On October 8, China shows only part of that pattern: production utilization remains low, but refinery inventories have risen and the national physical price average has barely changed.
The evidence therefore does not support describing the 7% futures rally as proof of a new nationwide physical shortage. It is more accurately interpreted as the futures market rapidly incorporating risks and price movements that accumulated while Chinese exchanges were closed.
The contrast becomes even clearer when individual physical markets are examined. Guangdong prices increased by around CNY 80 per metric ton on October 8 and Guangxi gained around CNY 70, but Zhejiang remained broadly unchanged while prices for some grades in Liaoning moved lower. Such differences show that local stock positions, refinery operations, weather and project demand continue to matter more than one uniform national shortage narrative.
Physical demand also remained selective after the holiday. In several regions, buyers were still purchasing mainly according to immediate requirements rather than rebuilding inventories aggressively. High bitumen prices and uneven road-construction activity continued to limit speculative or discretionary buying.
This is particularly relevant because the traditional September–October road-paving season has not produced uniformly strong consumption across China. Weather conditions, project financing and elevated binder prices have restrained demand in some areas even as supply has remained structurally lower than in previous years.
October production plans also show why the market should not become complacent about the inventory increase. Industry tracking of 92 Chinese bitumen producers put planned October output at approximately 1.577 million metric tons, virtually unchanged from the previous month but about 39.1% below the comparable period a year earlier. The current stock build therefore occurred against a production environment that remains substantially weaker on a year-on-year basis.
The market can consequently hold two apparently contradictory conditions at once. China does not appear to face an immediate nationwide shortage on October 8 because refinery inventories rose during the holiday and physical prices remained relatively stable, yet the underlying production base remains restricted enough to keep the market vulnerable if post-holiday demand accelerates.
The next stage will depend heavily on how quickly refinery inventories begin to move after logistics normalize. If road contractors, traders and distributors increase lifting sharply over the next one to two weeks, the 420,000-ton refinery stock level could begin falling again.
If inventories continue rising despite the reopening of transport networks and construction activity, that would indicate that demand is weaker than the futures rally currently implies. Such a development would increase the risk of a correction between futures expectations and physical-market fundamentals.
The relationship between futures and physical prices therefore deserves close attention. A futures rally can influence market expectations, refinery quotation strategies and trader behaviour even before physical supply becomes scarce. Sellers may become more reluctant to offer discounts, buyers may accelerate purchases and traders may rebuild inventories if they expect the futures move to persist.
In that way, a financial-market repricing can eventually affect physical conditions even when it did not begin with a shortage. If futures remain elevated long enough, market behaviour itself can tighten spot availability.
The opposite is also possible. If physical demand remains weak, refinery stocks continue accumulating and spot prices fail to follow futures higher, the gap between the two markets can become difficult to sustain. Futures would then face pressure to reconnect with physical fundamentals.
China’s imported bitumen market adds another layer to this picture. WPB’s first-week October assessment for 60/70 drummed bitumen stands at approximately $715–725 per metric ton CFR across major Chinese destinations, around $20 per metric ton higher than the previous assessment. That increase reflects firmer regional replacement values and tighter imported supply conditions, but it operates on a different commercial basis from domestic SHFE futures and Chinese refinery prices.
The imported CFR increase should therefore not be used as direct evidence that domestic refinery stocks are tight. Imported cargoes incorporate international supply, freight, packaging and destination costs, while SHFE futures reflect domestic expectations and refinery inventories measure actual physical material held at producers.
The three indicators can move in different directions over short periods, and October 8 provides a clear example. Imported values have strengthened, domestic futures have surged, but domestic refinery stocks have also risen and immediate physical prices have moved only marginally.
For the wider Asian bitumen market, this distinction matters because China can act both as a major consumer and, in some southern markets, as an alternative regional source. Southeast Asian buyers have recently been examining South China cargoes as Singapore availability tightens.
A sharp increase in Chinese domestic prices could reduce the commercial attractiveness of exporting South China material if internal values rise enough. However, the current refinery inventory build suggests that physical availability has not yet disappeared, and actual export behaviour will depend on regional price spreads rather than the futures move alone.
The market should therefore avoid translating a 7% futures gain directly into a 7% physical-price increase or an equivalent rise in export replacement costs. Futures and physical markets respond on different timelines and to different variables.
The strongest evidence of genuine physical tightening would come from a reversal in refinery inventories, stronger refinery shipment volumes, broad-based increases in regional cash prices and more aggressive downstream procurement. If those indicators appear together over the coming weeks, the October 8 futures rally could prove to have anticipated a real physical tightening.
If refinery stocks remain elevated and physical prices stay relatively stable, the rally will instead look more like a post-holiday financial repricing that moved ahead of spot fundamentals.
The year-on-year comparison remains important in either scenario. Refinery stocks may have increased 12% since September 28, but they are still more than 44% lower than a year earlier, while utilization remains significantly depressed. China therefore retains an underlying supply vulnerability even though the latest inventory data do not confirm an immediate shortage.
For the Chinese bitumen market, the key indicators to watch now are refinery inventory drawdowns, utilization rates, actual producer shipments, regional physical prices, road-project demand and whether SHFE futures can hold their post-holiday gains once the initial reopening adjustment has passed.
The first trading day after National Day has delivered a strong price signal, but the physical market has not yet delivered the same message. Until refinery inventories begin falling and cash-market prices strengthen more broadly, the more than 7% futures rally should be treated primarily as a sharp post-holiday repricing of market risk rather than proof that China has entered a new physical bitumen shortage.
