We know the U.S. is a big and liquid (though not really very transparent) market. We know that the rest of the world — led by Europe’s myriad issues, and China’s bursting housing bubble — is teetering on the edge of a precipice, and without a miracle will fall (perhaps sooner, rather than later). But we also know that America is inextricably interconnected to this mess. If Europe (or China or both) disintegrates, triggering (another) global default cascade, America will be stung by its European banking exposures, its exposures to global energy markets and global trade flows. Simply, there cannot be financial decoupling, not in this hyper-connected, hyper-leveraged world.
All of this suggests a global crash or proto-crash will be followed by a huge global money printing operation, probably spearheaded by the Fed. Don’t let the Europeans fool anyone, either — Germany will not let the Euro crumble for fear of money printing. When push comes to shove they will print and fiscally consolidate to save their pet project (though perhaps demanding gold as collateral, and perhaps kicking out some delinquents). China will spew trillions of stimulus money into more and deeper malinvestment (why have ten ghost cities when you can have fifty? Good news for aggregate demand!).
