I do not believe this was coordinated as it is the logical (and predictable) reaction to the radical shift in the energy market and to a lesser extent ongoing fears and impacts about the corona virus.
While I agree with your premise that there are many people who would deliberately tank the economy, I don’t think they anticipated the Saudis would act so boldly in their own interest (against Russia and Iran).
The fundamentals remain very strong in the U.S. and there are many upsides to cheaper oil despite a negative impact on smaller energy companies that need higher prices.
Agreed!!
