If it walks like a duck, acts like a duck, well then it is a duck. The linked article reeks of manipulation, but at a level that is truly appalling.
If Glencore was betting that Russia’s actions were to stop exports due to the fires, then that is not manipulation. (They were just betting on the likely outcome.) But if they influence the decision while having this trade on, well that just smells really really funny.
The CFTC and other global regulating bodies really need to stops this. It’s absolutely ridiculous.
(I have such distain for those who can not trade honestly.)
