Banks shifted from long-term lenders to intermediaries, losing the incentive to verify borrower creditworthiness.
Collateralized Debt Obligations recycled low-rated mortgage tranches into securities falsely labeled as Triple-A investments.
Rating agencies incorrectly assumed that local housing market defaults would never happen simultaneously across the nation.
Non-agency mortgage volume reached one point four eight trillion dollars by twenty-six, bypassing traditional federal oversight.
Credit Default Swaps allowed companies like AIG to insure global debt without holding sufficient cash reserves.
The crisis peaked when subprime teaser rates reset, causing defaults that climbed the waterfall to senior tranches.
