In other words, it was a black swan that almost no one, including mortgage market insiders, saw coming.
Fact 1: Resets of adjustable-rate mortgages did not cause the foreclosure crisis.
Fact 2: No mortgage was “designed to fail.”
Fact 3: There was little innovation in mortgage markets in the 2000s.
Fact 4: Government policy toward the mortgage market did not change much from 1990 to 2005.
Fact 5: The originate-to-distribute model was not new.
Fact 6: MBS, CDOs, and other “complex financial products” had been widely used for decades.
Fact 7: Mortgage investors had lots of information.
Fact 8: Investors understood the risks.
Fact 9: Investors were optimistic about house prices.
Fact 10: Mortgage market insiders were the biggest losers.
Fact 11: Mortgage market outsiders were the biggest winners.
Fact 12: Top-rated bonds backed by mortgages did not turn out to be “toxic.” Top-rated bonds in collateralized debt obligations (CDOs) did.
