If we consider past global conflicts like WW2 they were often preceded by global economic collapse. Once people starve, things become unstable and hawkish hardliners may step in to replace more moderate doves. War is then a way to deflect from leadership failures. Hence WW3.
I have no idea how it would be triggered, but do you people think this global economic collapse has set the stage for global war?

Market reflects uncertainty and fear (or their exact opposite: hope and confidence) it doesn’t cause them to begin with. So, no.
Could a poorly thought-out and poorly applied economical and radical geopolitical policy change bring the world closer to some kind of war(s)? Sure. It already did so in only 3 months.
For the first time in almost 80 years I see moderate people in my country, France, not radical anti-americans, real moderates, considering the USA as the real threat to our security and to world peace (and I may include myself in that count)… I would not be surprised the feeling was kinda similar, if not much worse, for Canadians, Greenlanders and, quite obviously, for Ukrainians.
