Nickel Market Fundamentals: A Quick Primer

Nickel feeds two large systems that you must track together. Stainless steel absorbs about seven tenths of primary nickel. Batteries take a rising share that moved from low single digits a decade ago to the mid teens. Class 1 is high purity metal. NPI is an iron rich feed for stainless. The link between them tightened because midstream plants can turn lateritic material into battery intermediates. Your daily job is to compare routes in dollars per nickel unit and secure the cheapest compliant ton.

Class 1 Nickel vs. NPI: Definitions, Specifications, and Use Cases

Class 1 includes cathode, briquette, and powder above roughly 99.8 percent purity. It suits sulfate plants and high grade alloys. NPI carries 5 to 15 percent nickel and feeds stainless furnaces. Technology lets you convert NPI or laterite leach products into matte, MHP, and sulfate if you manage impurities. That is why NPI discounts and Class 1 premia now move together more often.

Price Benchmarks and Market Structure

Exchange prices reference Class 1 metal. Physical premia and private indices bridge you to the real delivered cost. NPI pricing lives off exchange and is often converted to a nickel unit basis for clean comparison. Policy, freight, and liquidity shift these links quickly.

3.1 LME and SHFE Mechanics

LME sets a global reference for Class 1. Prompts run daily nearby, then weekly, then monthly. SHFE anchors domestic China pricing. If you hedge on LME while buying NPI or MHP, you carry basis risk. Treat that basis as a managed exposure, not noise.

3.2 Physical Premia and Discounts

Premia reflect location, form, credit, and logistics. They rise when inventories fall or when freight tightens. NPI trades at a discount to the LME equivalent on contained nickel. The discount narrows when stainless margins are firm or when conversion capacity is tight. It widens when stainless slows or when conversion runs well.

3.3 Liquidity, Inventories, and Warehouse Rules

On warrant stocks and load out rules shape near date stress. Thin inventories lift premia and amplify spikes. Off warrant holdings slow response time. Build governance that assumes trading can be disorderly and that margin calls can jump in hours.

Global Supply, Demand, and Regional Splits

Laterite heavy growth in Indonesia and ore supply from the Philippines set the pace for NPI and midstream. Sulfide routes in Russia, Canada, and Australia still anchor much of Class 1. Demand splits into stainless, batteries, and smaller industrial uses. Regional splits matter because scrap intensity, tariffs, and logistics differ.

4.1 Production by Country and Form

Indonesia leads primary output and hosts integrated parks that can switch between NPI, matte, MHP, and sulfate. China dominates stainless and midstream processing. The Philippines exports ore into Indonesian and Chinese systems. Sulfide producers supply a large share of Class 1 units.

4.2 Demand by Stainless, Batteries, and Other Uses

Stainless follows construction, white goods, and machinery. Batteries follow EV sales, storage additions, and chemistry choices. Other uses are steady but can tighten balances when supply is stressed.

4.3 Regional Stainless Cycles

China and Indonesia drive volume. India is adding melt capacity. Europe and Turkey lean more on scrap and swing imports quickly. The United States is smaller in tonnage but important for premia and trade rules.

Technology and Conversion Pathways

You win on specification control and yields. Know the routes and the math or you give away margin.

5.1 RKEF NPI

RKEF turns laterite ore into hot metal. Power tariffs, ore grade, reductants, and refractory life set cash costs. Moisture raises energy use. Port and inland logistics finish the picture.

5.2 HPAL, Matte, MHP, Sulfate

HPAL leaches ore with acid under pressure and yields MHP or similar intermediates. Some parks convert NPI into matte for onward refining. Sulfate plants take Class 1 or MHP to make battery grade chemicals. Route choice swings with power costs, acid prices, premia, and recovery.

5.3 Conversion Yields, Moisture, and Impurity Control

Work in nickel units. One tonne of 10 percent NPI carries 0.10 tonnes of nickel. At 90 percent recovery from NPI to MHP, you need 11.11 tonnes of that NPI to deliver one tonne of nickel in MHP. Moisture and impurity penalties apply when assays drift. Put sampling methods, labs, and reconciliation clocks into every contract.

Cost Curves and Margin Drivers

Think in bands with two or three key sensitivities. Example only. If LME Class 1 is 18,000 dollars per tonne of nickel and 10 percent NPI trades at 75 percent of LME on contained nickel, NPI costs 1,350 dollars per tonne. At 90 percent recovery you need 11.11 tonnes, so NPI input equals about 15,000 dollars per tonne of nickel in MHP. Add 2,500 dollars for conversion and 500 dollars for logistics. Your implied MHP nickel cost lands near 18,000 dollars. If the NPI discount widens to 65 percent, MHP undercuts Class 1 plus sulfate conversion. If power or acid spikes, the advantage can flip inside a week.

Carbon, Power Mix, and ESG Verification

Power mix sets most of the footprint. Coal heavy grids raise carbon intensity versus gas or hydro. HPAL footprints depend on energy and acid sourcing. Buyers now ask for verified energy mix, carbon ranges, and audit rights. Many contracts include a narrow price band tied to verified emissions. If you sell into battery chains, expect mandatory reporting.

Scrap and Recycling Dynamics

Scrap is your pressure valve. Europe and Turkey run high scrap shares. China's share rises but sits lower. When demolition and collection rise, mills lift scrap ratios and cut NPI spot buys. That caps primary price spikes. When scrap tightens, primary units carry the load, and prices move faster.

Policy and Trade

Policy changes move more tonnes than normal cycles. Indonesia's ore rules forced capital into local refining. Royalty or export tweaks can redirect flows within a quarter. US critical mineral rules and EU carbon reporting reshape premia and credit eligibility. China can adjust export or VAT rules that affect midstream shipments. Keep a quarterly policy calendar with the price channel each lever hits.

Scenario Analysis: Crosswinds and Stress Paths

Fast EV uptake lifts the share that must meet chemical specs. If conversion keeps up, premia stay contained. If it lags, Class 1 tightens and premia rise. A stainless upcycle lifts NPI first, then pulls intermediates if margins justify conversion. A scrap surge softens both markets and narrows spreads. A policy or freight shock lifts premia and forces near term product switches. Pre write your response for each path.

Case Studies

Real behavior shows what works.

11.1 Stainless Led Cycle Europe

A mill faced weak scrap intake and rising NPI premia. Output was trimmed to protect margins. Six months later, demolition and appliance replacement waves lifted scrap flows. The mill locked quarterly scrap with quality tracking, cut NPI spot purchases, and recovered spreads.

11.2 Battery Led Contracting North America

An automaker using high nickel chemistries signed multi year Class 1 offtake from a low carbon producer and added a tolling option to receive MHP if conversion lines met impurity targets. The mix reduced exchange exposure and kept credit eligibility intact while preserving flexibility.

11.3 NPI to Midstream Switch Indonesia

An operator toggled from pure NPI to more matte and MHP when stainless margins compressed. Reagent changes lifted nickel recovery from 88 to 91 percent. Implied nickel cost per tonne fell and more units flowed into battery chains at better netbacks.

Procurement and Hedging Playbook

Write rules before the market tests you. Keep optionality across forms in every term sheet. Allow settlement or delivery in NPI, matte, MHP, or sulfate within impurity and moisture windows. Specify assay labs, moisture handling, and reconciliation timelines. Separate logistics from commodity pricing so you can change load ports without reopening value.

Hedge both markets together. Set target hedge ratios by quarter. Define acceptable basis bands between your physical exposure and the exchange. Hold cash buffers sized for severe margin calls. Name who can pause trading during stress and document the steps. Add carbon and data clauses with a small price band tied to verified improvement. Keep modest safety stocks of key intermediates at neutral hubs.

Monitoring Dashboard and Weekly KPIs

Track Chinese stainless output by grade and region. Track Indonesian shipments of NPI, matte, and MHP by park. Track EU and Turkish stainless scrap prices and collection signals. Track EV registrations and chemistry shares in China, the EU, and the United States. Track LME inventories, on warrant versus estimated off warrant. Track regional premia, power tariffs, and acid prices. Maintain a live chart of the NPI discount to LME on a nickel unit basis. If several indicators flash red in the same week, slow purchases and add hedges.

FAQs

What breaks the link between Class 1 and NPI?

Conversion capacity and recovery. If recovery falls or reagents tighten, Class 1 premia rise and the link weakens.

Why did scrap mute a rally?

Scrap surged after a lull in demolition and collection. Mills cut NPI spot buys and capped nickel unit prices.

How do you compare NPI and MHP offers fast?

Convert both to dollars per tonne of nickel content. Add recovery, conversion, freight, and working capital. Choose the lowest compliant all in nickel unit.

Do you need LFP in your model?

Yes. LFP growth lowers nickel intensity per vehicle in some segments. High nickel chemistries still anchor performance and long range.

What is a practical carbon clause?

Ask for verified energy mix and carbon ranges plus audit rights. Tie a narrow price band to those numbers.

When should you switch from NPI to Class 1?

Switch when the NPI discount narrows below your conversion and recovery threshold or when carbon adjustments lift the implied cost above Class 1 plus sulfate conversion.
