Between Aug. 1929 – Jun. 1932 The U.S. Market Lost -83.8%. What would happen if the same happened in Aug. 2026 - Jun. 2029?

Obviously, no one has the crystal ball to answer this question but I feel as though there's some value (albeit possibly only entertainment value) in hypotheticals that test the limits of the current state of the U.S. and global economies. On the one hand, we made it through the depression once, why not again? On the other hand, the country and the world is much more fractured while at the same time much more interconnected. One domino the size of the U.S. economy falling nearly 90% would amount to most of the entire global economy falling apart. Not to mention the geopolitical involvement of today is of a much larger kind and the failure of the U.S. economy at such a level might give rise to even more turbulence in that realm.
