In late Sept 2023, UBS published a research report on natural graphite1:

  • Natural graphite looks to be preferred inlow-costlower-carbon profile LFP batteries
  • Natural graphite market share in the anode could increase from 30% today to 50% by 2030
  • Forecasting a 6x growth in natural graphite demand by 2030 to 6.3mt

This forecast would require ~5mt of new natural graphite supply by 2030 or around 14 new mines

the size of Syrah's Balama mine (based on a nameplate capacity of ~350ktpa)2.

Given the significant barriers to entry for new natural graphite supply, Black Rock believes this scenario would likely lead to substantial supply deficits and much higher graphite prices.

Based on Benchmark Mineral Intelligence data, Black Rock estimates >50% of global natural graphite mine supply is breakeven/loss making at current prices, which is clearly not sustainable

In addition, there is growing evidence of premium prices for ex China fines due to new US and EU restrictions and US 25% tariffs on graphite sourced from China
