Once upon a time, those who made loans would profit only if the loan were paid back. If the borrower defaulted, the lender would suffer.
That idea must have seemed quaint in 2005, as the mortgage lending boom reached a peak on the back of mushrooming private securitizations of mortgages, which were intended to transfer the risk away from those who made the loans to investors with no real knowledge of what was going on.
Less well remembered is that there was a raft of real estate securitizations once before, in the 1920s. The securities were not as complicated, but they had the same goal — making it possible for lenders to profit without risking capital.
The Dodd-Frank Act of 2010 set out to clean that up. Now, there would be “risk retention.” Lenders would have to have “skin in the game.” Not 100 percent of the risk, as in the old days when banks made mortgage loans and retained them until they were paid back, but enough to make the banks care whether the loans were repaid.
