I agree with you on the limitations of the article, and I can see the rise in nickel prices due to the war as "real macroeconomic phenomena", but the short squeezes on nickel produces clearly created a positive feedback loop that pushed the price way higher than the fundamentals justified.

If the LME had a circuit breaker (and I'm sure they'll be getting one soon), this wouldn't have even come up.
