On a private forum, I just listed possible outcomes and probabilities as:
US leaves Persian Gulf and Eurasian powers work with Iran to establish new economic and security order there, 10%
Islamic Republic falls and is followed by new Eurasian democracy crusade ultimately aimed at Russia and China, 60%
Regime falls but no broader democracy crusade OR regime stays but strait is reopened, 30% combined
These are political scenarios and you’re asking about economics. My intuition is that there could be a world recession but not a world depression.
I suggest contacting the International Society of Solipsists, they may have some relevant organizational experience…
