The damage to S&L operations led Congress to act, passing a bill in September 1981 allowing S&Ls to sell their mortgage loans and use the cash generated to seek better returns. This all made S&Ls eager to sell their loans. The buyers – major Wall Street firms – were quick to take advantage of the S&Ls' lack of expertise, buying at 60%-90% of value and then transforming the loans by bundling them as, effectively, government-backed bonds (by virtue of Ginnie Mae, Freddie Mac, or Fannie Mae guarantees). S&Ls were one group buying these bonds, holding $150 billion by 1986, and being charged substantial fees for the transactions. 

A large number of S&L customers' defaults and bankruptcies ensued, and the S&Ls that had overextended themselves were forced into insolvency proceedings themselves.  A Federal Reserve Bank panel stated the resulting taxpayer bailout ended up being even larger than it would have been because moral hazard and adverse selection incentives that compounded the system’s losses.
