- High-grade Indonesian nickel matte barely moved, at $15,478/mt Ni on August 21 versus $15,490/mt Ni on August 19, with SMM describing its supply as tight and seller offers as firm.
- SMM linked the MHP payable pressure to weak nickel sulphate and cobalt sulphate prices, which have reduced how much Chinese battery-material plants are willing to pay for MHP feedstock.
- LME refined nickel rose about 0.45% on August 21 to around $17,000 a tonne, moving in the opposite direction to MHP's cobalt payable.
Indonesian MHP cobalt payables slid from 80% to 78% between August 19 and 21 on weak sulphate demand, while nickel payables and nickel matte prices held nearly flat.
Analysis 73% confidence
Nickel's battery-material supply chain is really several linked markets, and the two trading sessions to August 21 showed them moving at different speeds rather than in lockstep. MHP, the intermediate nickel-cobalt hydroxide Indonesian processors produce by leaching laterite ore in sulphuric acid, is priced two ways at once: a nickel component and a cobalt component, each set as a "payable" — a discount against a separate finished-product benchmark. The nickel side held up reasonably well. MHP's FOB nickel price eased only modestly, to $14,850 per tonne of contained nickel from $14,945, and its payable against the SMM battery-grade nickel sulphate index was essentially flat, 83-84% against 83-84.5% two days earlier.
The cobalt side told a different story. MHP's FOB cobalt price dropped to $40,287 per tonne of contained cobalt from $41,267, and more tellingly, its payable against SMM's Rotterdam refined cobalt benchmark fell two full percentage points, to 78% from 80%. A payable is the mechanism by which weak demand for a finished product gets transmitted back to the raw-material producer: when Chinese salt plants that buy MHP to make nickel sulphate and cobalt sulphate see softer prices for what they sell, they push back harder on what they'll pay for the MHP they buy, and that pushback lands first and hardest on whichever component — nickel or cobalt — is under more demand pressure. SMM's own reporting points to weak nickel sulphate and cobalt sulphate prices as the direct cause, but the two-percentage-point cobalt payable slide against a comparatively steady nickel payable shows that pressure wasn't spread evenly.
High-grade nickel matte sat almost entirely outside this dynamic. Its FOB price, at $15,478 per tonne of contained nickel, was barely changed from $15,490 two days earlier — a move of less than a tenth of a percent. SMM described matte supply as tight, with sellers keeping offers firm, and noted that matte offers buyers stronger cost-effectiveness than MHP at current pricing. That resilience isn't just a coincidence of timing: matte functions as an alternative feedstock route into the same battery supply chain, competing with MHP for buyers who need contained nickel units, so when one route's economics come under pressure, buyers with the option to switch add support to the other. SMM's analysts went further, describing high-grade nickel matte payables as unlikely to decline given expected tightening in MHP supply ahead and matte's role as a substitute raw material.
The backdrop matters too. Benchmark refined nickel on the LME rose roughly 0.45% on August 21, to around $17,000 a tonne, moving in the opposite direction from MHP's cobalt payable on the same day. That gap is the clearest evidence that the headline nickel price and the feedstock economics feeding into it are not the same market: a trader watching only the LME ticker on August 21 would have seen a small gain and missed that, one rung down the supply chain, cobalt-linked payables for Indonesian raw material were sliding on soft Chinese demand for the finished battery chemicals.
Why This Matters 63% confidence
Battery-material buyers and Indonesian nickel producers watch payable rates, not just the headline nickel price, because payables are where weak demand for finished battery chemicals shows up first — and the fact that MHP's cobalt payable slid two points while its nickel payable and high-grade nickel matte barely moved shows that pressure in this supply chain is landing unevenly, not uniformly, across nickel, cobalt and feedstock grade.
Price Impact
The nickel battery-feedstock complex sent mixed signals over the two sessions to August 21: MHP's cobalt payable fell two points on weak sulphate demand while its nickel payable and high-grade nickel matte held nearly flat, and LME refined nickel itself ticked up slightly — a genuine divergence within the supply chain rather than a single clear directional move for nickel overall.

Fundamental Analysis
Demand Drivers 70% confidence
Weak prices for nickel sulphate and cobalt sulphate, the finished battery-precursor materials Chinese salt plants make from Indonesian MHP, have reduced how much those plants are willing to pay for MHP feedstock, pushing MHP's cobalt payable down to 78% from 80% between August 19 and 21, while its nickel payable held closer to steady at 83-84%.
Supply Drivers 66% confidence
Sulphur arrivals at Indonesian ports have concentrated recently, letting some MHP production lines recover output schedules and improving overall available volume for external sale, while high-grade nickel matte supply remains comparatively tight, with sellers keeping offers firm and prices barely moved between August 19 and 21.
Refinery Output 60% confidence
Indonesian MHP is produced by leaching nickel-bearing laterite ore in sulphuric acid; improved sulphur availability at port has allowed some MHP production lines to recover output, even as the payable rate producers receive for the cobalt portion of that output has come under clearer pressure than the nickel portion.
Country Impact 66% confidence
| Country | Impact | Reason |
|---|---|---|
| Indonesia | High | Indonesia is the source of the MHP and high-grade nickel matte feedstock whose FOB prices and payable rates moved unevenly between August 19 and 21, directly affecting the revenue producers realize from the same underlying tonnage. — Indonesian FOB MHP cobalt payables fell to 78% from 80%, while nickel payables held near-flat at 83-84% and high-grade nickel matte prices barely moved, from $15,490/mt Ni to $15,478/mt Ni. |
| China | Medium | Chinese battery-material salt plants are the buyers converting Indonesian MHP into nickel sulphate and cobalt sulphate, and it is weakness in the prices they sell those finished materials for that SMM linked to the lower MHP payable rates. — SMM said weak nickel sulphate and cobalt sulphate prices reduced salt plants' price acceptance for MHP, pressuring nickel and cobalt payables downward. |
Industry Impact 58% confidence
| Industry | Effect | Reason |
|---|---|---|
| Battery Manufacturing | Neutral | Lower MHP cobalt payables reduce feedstock costs for the battery-material supply chain in principle, but the same weak nickel sulphate and cobalt sulphate prices driving that payable decline also reflect soft demand conditions for the finished precursor materials battery makers ultimately rely on. |
| Mining | Negative | Indonesian MHP producers are realizing a smaller share of the benchmark cobalt index for the same contained-cobalt tonnage, directly reducing revenue per tonne on the cobalt side even as nickel payables and production volumes held comparatively steady. |
Timeline
2026-08-19: SMM assesses Indonesian FOB MHP at $14,945/mt Ni (83-84.5% nickel payable) and $41,267/mt Co (80% cobalt payable), with high-grade nickel matte at $15,490/mt Ni.
2026-08-21: SMM assesses Indonesian FOB MHP at $14,850/mt Ni (83-84% nickel payable) and $40,287/mt Co (78% cobalt payable), with high-grade nickel matte nearly unchanged at $15,478/mt Ni; LME refined nickel rises about 0.45% to around $17,000/mt.
Market Sentiment
Bullish Factors 58% confidence
- High-grade nickel matte supply remains tight, with sellers holding offers firm and prices barely moved over the two sessions to August 21.
- MHP's nickel payable held nearly flat at 83-84%, showing the pressure was concentrated on the cobalt side rather than spread across the whole feedstock.
- LME refined nickel rose about 0.45% on August 21 to around $17,000 a tonne.
- Better sulphur availability at Indonesian ports is letting some MHP production lines recover output.
Bearish Factors 62% confidence
- MHP's cobalt payable against SMM's Rotterdam refined cobalt benchmark fell to 78% from 80% between August 19 and 21, on weak cobalt sulphate demand.
- MHP's FOB cobalt price dropped to $40,287/mt Co from $41,267/mt Co over the same two sessions.
- Weak nickel sulphate and cobalt sulphate demand has reduced Chinese salt plants' willingness to pay up for MHP feedstock generally.
Alternative Scenarios 53% confidence
- If cobalt sulphate prices stabilize or recover, Chinese salt plants could regain willingness to pay higher MHP cobalt payables, reversing part of the recent slide toward 78%.
- If MHP supply tightens again as SMM's analysts anticipate, high-grade nickel matte's role as an alternative feedstock could keep its payables firm even if MHP's stay under pressure.
- If sulphur availability at Indonesian ports continues improving, MHP output could keep recovering, which could extend rather than ease payable pressure if downstream demand doesn't recover alongside it.
Who Benefits, Who Loses
| Party | Stance | Reason |
|---|---|---|
| Chinese nickel sulphate and cobalt sulphate producers | Bullish | Lower MHP cobalt payables mean these battery-precursor producers are paying less for the cobalt content of their main raw material relative to the finished-product benchmark, supporting their margins during a period of weak sulphate prices. |
| Indonesian MHP producers | Bearish | A lower cobalt payable rate against the Rotterdam benchmark means these producers are earning less for the cobalt portion of the same MHP tonnage, even as the nickel portion and high-grade nickel matte held comparatively steady. |
Investor Watchlist 60% confidence
Educational items to monitor — not investment advice.
- Whether cobalt sulphate prices stabilize, which would affect Chinese salt plants' willingness to pay higher MHP cobalt payables
- MHP nickel and cobalt payable rates against SMM's benchmark indices in coming daily reviews
- High-grade nickel matte payable rates and prices, to see whether tightness continues holding them firm relative to MHP
- Sulphur availability at Indonesian ports and its effect on MHP production recovery
Price Risks 54% confidence
- Continued weak cobalt sulphate prices could keep pressuring MHP's cobalt payable lower even if the nickel payable and matte prices stay comparatively steady.
- A rebound in downstream battery-material demand could lift MHP payables back toward recent higher levels if Chinese salt plants regain pricing power to pay up for feedstock.
