@LiBoyHey Lithium boy, don't think there is a universally agreed world lithium price. The LME are trying to establish theirs.
(Following extensive consultation with the lithium industry, the London Metal Exchange is partnering with price reporting agency Fastmarkets to promote market acceptance of Fastmarkets’ lithium reference prices. Continued adoption of reference pricing across the industry will pave the way for the launch of an LME lithium futures contract.)
I check the LIT ETF each morning as an indicator,
Global X Lithium & Battery Tech ETF (LIT)
But you probably already know.
If not, hope that helps.
