The world is in its most precarious geopolitical environment since World War 2. The big question is whether or not WW3 will go nuclear. And if it does, will it be just some relatively small-yield tactical bombs used against military formations? Or will it get out of control, with strategic weapons used against cities? Either is possible.
Let's just hope NATO doesn't back the Russians into a corner, the Zelensky regime stays out of NATO, and the Israelis don't go nuclear against the Iranians.
As WW3 develops, I don't think there's any question it will have significant cyber aspects as well. The whole world runs on computers. Computers control utilities, transport, the banking system, communications, commerce, distribution, and everything else. If computer networks are massively hacked it could collapse civilization. The result could be mass starvation after a couple of weeks.
And, of course, there's a real possibility of biological warfare. If any of these things happen, it increases the odds of all of them happening. 
So price movements in the commodity and financial markets will likely be the least of our problems (see chart). Let's assume, therefore, that things don't go beyond a regional level.
One current difference in how WW3 is evolving is that almost all of the governments of the world are already bankrupt. Historically, governments only go bankrupt during or after wars; this time they're all bankrupt before the war has really even started. They're all welfare states with huge fixed domestic spending. They already have an unrepayable amount of debt. That's never been the case previously.
