alt Hacker NewsNo, banks collateralizing mortgages caused it.

> In the early 2000s, the debt underpinning CDOs was generally diversified, but by 2006–2007—when the CDO market grew to hundreds of billions of dollars—this had changed. CDO collateral became dominated by high risk (BBB or A) tranches recycled from other asset-backed securities, whose assets were usually subprime mortgages. These CDOs have been called "the engine that powered the mortgage supply chain" for subprime mortgages, and are credited with giving lenders greater incentive to make subprime loans, leading to the 2007–2009 subprime mortgage crisis.
It's hard to ignore the similarities.

Another factor in that case was that the government regulated, in some cases, the ratings of bonds that entities were allowed to buy (they couldn't be as highly levered with lower rated bonds) and so there was an incentive for bond ratings to be falsely inflated, happily carried out by the rating agencies. Of course collateralized junk is still junk, and many people at the time knew that, but there was money to be made in looking the other way.
It’s also hard to ignore differences. Bubbles gonna bubble, but the consumer is quite healthy this time around. Burry being short doesn’t make it 2008.
No, to be more specific, banks selling the collateralized mortgages that were subprime in risk as if they were prime and these risk ratings being accepted at their word and via collusion with the ratings agencies is what caused this.
There is no issue with collateralized debt as long as the risk is properly assessed, the whole point of securitization is that you can take on higher risk for higher reward of an asset that was previously just one single piece of risk.
