What if Pacific seabed nodule mining wins approval?
ISA approval of nodule extraction threatens a future Ni/Co/Mn wave — but it's a 3-10y option, so spot impact is a sentiment cap on terrestrial miners (Freeport, nickel names), not a price collapse today. Rhymes with the early-2010s deep-sea hype (Nautilus Minerals) that pressured nickel sentiment then fizzled on cost/permitting. Transmission: Indonesia (nickel) and DRC (cobalt) face the eventual share loss. Forward: financing and ESG litigation likely delay first production well past the headline, so fade the immediate bearish read.

What it would mean
If this plays out, it is a mixed shock. The ISA greenlights commercial polymetallic nodule extraction, threatening a future flood of nickel, cobalt, and manganese. The trigger decomposes into signed root‑shocks — Industrial demand ▼ — which propagate through our causal graph to the markets below.
