Chemical Prices Today (October 19, 2026): Daily Market Trends & Price Changes

Daily Chemical Market Price Overview — October 19, 2026

The losing streak finally broke. 35 of 79 tracked products moved — 12 higher against 23 lower, the best up/down balance of the week — and 44 lines did not move at all. The front of the board belonged to energy again: WTI Crude Oil rose 3.06% to USD 101/barrel, extending its weekly gain to 5.21% and pushing the tracked line back above the round hundred, while the battery chain delivered the day’s most consequential reversal — lithium carbonate climbed 1.98% to CNY 103,000/ton, snapping the thirteen-session decline flagged in the last edition, and Nickel added 1.62% to CNY 119,283/ton. Against them, Sulfur collapsed 8.64% to CNY 6,077/ton, the deepest genuine decline of the session, Acetic acid fell 4.16% to CNY 4,610/ton, and Cobalt lost a further 2.45% to CNY 242,700/ton. One honesty note up front: like the October 16 edition, this one again carries two base-day artefacts. PTMEG printed an 11.76% gain and Anthracite a 10.0% fall, and both are corrections of anomalous October 18 quotes rather than genuine moves — they are excluded from all headline analysis below.

Three forces shaped the day. First, the basket contracted again, from 106 to 79 tracked products, as a net twenty-seven lines left coverage — including both polyvinyl chloride lines, so last week’s supply-led rebound can no longer be tracked, plus potassium sorbate, silver iodide, mineral oil and most of the specialty book added last week; the two artefacts above instead come from the lines that stayed, which is why the caveat is needed again. Second, crude found a floor and stayed on it: the Hormuz premium kept the physical market above USD 100 and pulled the tracked line back to 101, +5.21% on the week, yet the domestic tape kept decoupling from it — Benzene, Toluene and Propylene all fell the same day oil gained 3%. Third, the battery chain split: lithium carbonate’s bounce and nickel’s recovery came against cobalt’s continued slide, and with lithium still 2.44% below week-start and 15.98% below month-start, today reads as an oversold snap-back inside a downtrend, not the end of one.

WTI Crude Oil prices ↑ 3.06%

WTI Crude Oil rose 3.06% to USD 101/barrel from USD 98/barrel — the tracked line’s return above the round hundred and the largest genuine gain on the board once the artefacts are stripped. The weekly clock now reads +5.21% while the month is still 2.11% negative: the barrel is back roughly where October began, but with a materially higher geopolitical floor underneath it. The mechanics are last edition’s carried forward — Hormuz transit stuck near 70% of pre-war throughput, war-risk premia re-entering freight and inspection costs, and an inventory picture, after the 8.56-million-barrel EIA draw, that leaves no cushion if another vessel is hit. The offsets are the same list the market has been trading against all week: coordinated reserve volumes, product builds and visible demand fatigue in a tape where the domestic chemical board printed red anyway. That divergence is the number that matters to chemical buyers: crude +3.06% today, benzene minus 0.86%, toluene minus 0.86%, propylene minus 1.40% — the cost-push has so far stayed at the wellhead. On the month the tracked line is still 2.11% lower; this is a risk premium, not a demand signal, and it unwinds as fast as headlines do.

Price rose 3.06% today — a second session above USD 100 on the Hormuz premium, +5.21% on the week but still 2.11% below month-start. The tell for chemicals is the decoupling: oil up, the domestic aromatic and olefin chains down. Rising energy cost against flat-to-lower chemical prices is still a margin story, not a demand story.

Lithium carbonate prices ↑ 1.98%

Lithium carbonate rose 1.98% to CNY 103,000/ton from CNY 101,000/ton, breaking the thirteen-session losing streak that carried it through last week’s 18.88% weekly collapse and a year-to-date low below the 100,000 round number. This is the most consequential single print on the board: spot reclaimed the round floor within a week of the futures contract closing at 96,320 yuan last Friday. But the position is fragile. Spot had merely been flat at CNY 101,000/ton on October 18 before today, the weekly reading is still 2.44% negative, the monthly reading 15.98% negative, and the two lithium hydroxide lines that took the worst slots on October 16 (industrial minus 6.82%, battery grade minus 5.88%) have left coverage — so the bounce cannot yet be corroborated across the chain. The split inside the battery complex sharpens the picture: Nickel added 1.62% to CNY 119,283/ton while Cobalt fell a further 2.45% to CNY 242,700/ton, 4.65% on the week and 9.42% on the month, with nothing on the board arguing against it. Read together, lithium’s move has the signature of short-covering at an oversold print rather than a demand turn: cathode offtake has not re-accelerated anywhere in the tracked tape. For buyers the practical translation is to treat CNY 101,000–103,000 as a two-way zone now, not a confirmed floor — and to watch whether the next print holds above 100,000.

Price rose 1.98% today — the first up-print after the thirteen-session losing streak, taking spot to CNY 103,000/ton from an unchanged 101,000 on October 18. But weekly is still -2.44% and monthly -15.98%, and the hydroxide lines left coverage, so this is an oversold bounce inside a downtrend, with nickel firm and cobalt still falling on either side of it.

Sulfur prices ↓ -8.64%

Sulfur fell 8.64% to CNY 6,077/ton from CNY 6,652/ton — the deepest genuine chemical decline of the session, and the clearest failure of a floor the previous edition had marked as formed. The line is now 11.91% lower on the week and 9.37% below month-start, worst on the board once both artefacts are stripped. The downstream chain is where the information sits. Sulfuric acid sat unchanged at CNY 1,558/ton for a second session, but its monthly clock (-7.26%) is acid-plant economics chasing a collapsing feedstock with a lag, and Sodium metabisulfite eased 0.26% to CNY 3,883/ton — the freeze flagged on October 16 held only while sulfur’s own pause held, and that pause failed after one session. The pass-through conversation is no longer theoretical: the first downstream markdown is already in the prints. Sulfur is a by-product commodity — its supply tracks refinery runs and copper-smelter output, not chemical demand — which means there is no orderly producer response to a slide like this; the realistic read is that acid and sulfite lines stay under discount pressure until the weekly clock stops printing double digits. White phosphorus, the other sulphur-adjacent red line, slipped only 0.18% to CNY 28,246/ton, keeping the phosphate complex insulated for now.

Price dropped 8.64% today — the deepest genuine fall of the session, -11.91% on the week, reversing the floor that formed last week. Metabisulfite has already marked down one session after the feedstock moved, sulfuric acid is frozen but its monthly gap is widening: the pass-through is live again.
