The global nickel market will maintain an operational surplus through 2027. This trend is driven by recovering Indonesian output and cheaper intermediate input costs. Japan’s top smelter, Sumitomo Metal Mining, released its latest half-year outlook on Tuesday. Global supply will continue outpacing demand through the forecast period. Meanwhile, demand grows across electric vehicle batteries, stainless steel, and AI data centers.
Indonesian Supply Rebound Eases Class 2 Tightness
SMM forecasts a global nickel surplus of 34,000 metric tons in 2027. This represents a slight narrowing from 38,000 metric tons in 2026. Rebounding Indonesian nickel pig iron (NPI) production drives this persistent oversupply. SMM expects low-grade NPI output to surge 11.9% to 1.88 million tons. This recovery follows a temporary 2.3% contraction in 2026 due to government mining quota cuts. Indonesia produces over 60% of global nickel. Higher mining quotas should ease near-term supply bottlenecks for Class 2 nickel.
Cheaper Inputs and AI Demand Shift Market Fundamentals
Intermediate production like mixed hydroxide precipitate (MHP) is also set to expand. Lower costs for sulfur and sulfuric acid support this output growth. Global nickel demand will expand 6% to 3.92 million tons in 2027. Meanwhile, total supply will increase 5.8% to 3.96 million tons. Stainless steel remains the primary demand driver for global nickel. However, specialty steel for AI data centers is emerging as a key growth area. Electric vehicle battery manufacturing also maintains steady demand expansion.
Bifurcated Dynamics Across Class 1 and Class 2 Segments
The balance between refined nickel categories is shifting rapidly. Rebounding Indonesian NPI output will ease tight conditions for Class 2 nickel. Concurrently, Chinese cathode production is softening. This trend will help reduce the structural surplus of high-purity Class 1 nickel. Battery sector demand continues its strong upward trajectory. Battery nickel consumption will reach 620,000 tons in 2027, up from 560,000 tons in 2026. Expanding EV sales in China remain the primary engine of this growth.

SuperMetalPrice Commentary:
Sumitomo Metal Mining’s projection highlights key structural shifts in the nickel market. Rebounding Class 2 supply caps upside pricing for stainless steel inputs. Meanwhile, lower MHP intermediate costs offer margin relief to battery cathode producers.
Market participants should watch AI data center construction closely. This sector could absorb significant volumes of specialty nickel. If Chinese cathode production slows further, Class 1 surpluses may narrow faster than expected.
