he argument for preserving Glass-Steagall (as written in 1987):

1. Conflicts of interest characterize the granting of credit – lending – and the use of credit – investing – by the same entity, which led to abuses that originally produced the Act

2. Depository institutions possess enormous financial power, by virtue of their control of other people’s money; its extent must be limited to ensure soundness and competition in the market for funds, whether loans or investments.

3. Securities activities can be risky, leading to enormous losses. Such losses could threaten the integrity of deposits. In turn, the Government insures deposits and could be required to pay large sums if depository institutions were to collapse as the result of securities losses.

4. Depository institutions are supposed to be managed to limit risk. Their managers thus may not be conditioned to operate prudently in more speculative securities businesses. An example is the crash of real estate investment trusts sponsored by bank holding companies (in the 1970s and 1980s).
