Greenland bans deep-sea mining

The ban blocks prospective extraction of seabed minerals, constraining future supply of mining inputs from Greenland.

The trace

How it reaches your house.

Starting from Neo Performance Materials, we walked the supply graph hop by hop to the goods you buy and the companies you own. Each step is the engine’s reasoning, scored for confidence and cited where a source backs it.

First impact
Rare-earth elements (NdPr) →Shortage risk
Rare earth magnets
Rare earth magnets are a critical downstream use of NdPr, so constraining Greenland-linked NdPr supply should tighten magnet availability.
96% confidence
Rare-earth elements (NdPr) →Stands to benefit
China
China supplies 70% of NdPr, so a tighter global supply outlook should disproportionately favor the dominant incumbent supplier.
62% confidence
Rare-earth elements (NdPr) →Stands to benefit
MP Materials Corp.MP
MP Materials has a 12% NdPr supply share and can benefit as alternative supply becomes more valuable, though substitutes still exist.
57% confidence
Rare-earth elements (NdPr) →Stands to benefit
Lynas Rare Earths Ltd.
Lynas supplies 8% of NdPr and could gain from tighter supply conditions, but the smaller share keeps the effect modest.
54% confidence
PGM Sulfide Ore — Russian Arctic (Norilsk/Taimyr) →Prices rise
Palladium and platinum group metals
Greenland's deep-sea mining ban trims prospective seabed mineral supply, tightening the broader PGM market and pushing prices higher for the metal basket this ore feeds.
48% confidence
PGM Sulfide Ore — Russian Arctic (Norilsk/Taimyr) →Stands to benefit
MMC Norilsk Nickel (Nornickel)GMKN
As the sole qualified supplier of this PGM ore stream, Nornickel stands to gain from less future Greenland competition and firmer PGM pricing.
44% confidence
Hop 2
MP Materials Corp. →Prices rise
Neodymium-Praseodymium (NdPr) Oxide/Metal
Greenland's mining ban tightens prospective rare-earth supply, which should lift prices for MP Materials' NdPr oxide/metal output given its 15% share, low substitutability, and 24-month replacement lead time.
63% confidence
China →Prices rise
Terbium (Tb) Metal
Terbium is a rare-earth metal, and China accounts for about 95% of its supply, so a ban that tightens prospective rare-earth output from Greenland should support terbium prices by making alternative supply scarcer.
58% confidence
Rare earth magnets →Shortage risk
Rare-earth elements (NdPr)
Hop 3
Terbium (Tb) Metal →Shortage risk
Rare earth magnets
Terbium metal is a critical input to rare earth magnets, so a supply constraint in Tb metal would likely tighten magnet availability and production.
