It’s been widely assumed that the financial crisis spread from the United States to the rest of the world because foreign institutions held dangerous amounts of Wall Street’s sub-prime mortgage paper. But a startling paper by Federal Reserve Board economists Steven B. Kamin and Laurie Pounder DeMarco concludes the contagion was indirect – that the collapse of the U.S. housing market was the trigger, not the cause, of the global meltdown. They put the blame on some (other) sources of bank instability: “the opacity of their balance sheets; excessive dependence on short-term funding; vicious cycles of mark-to-market losses driving fire sales of MBS; the realization that financial firms around the world were pursuing similar (flawed) business models; and global swings in risk aversion.”
