NEW YORK (TheStreet) -- During the Occupy Wall Street protests last fall, it was not unusual to see signs urging the return of the 1933 Glass-Steagall Act.
But according to panelists at the Securities Traders Association of New York on Thursday, the landmark Depression-era law that separated commercial banks, securities firms and insurance companies, undone in 1999 by legislation known as the Gramm Leach Bliley Act, is now effectively back on the books.

Of course the major business these banks will exit, if they haven't done so already, is proprietary trading. Many prop traders at Goldman, JPMorgan, Morgan Stanley and Citigroup have already anticipated the rule and left the company to set up hedge funds.
More surprising and controversial, however, is the argument that these institutions will exit fixed income market making.

A market maker is merely a go-between: buying a bond or some other product from one party and selling it to another. A proprietary trader, on the other hand, takes a directional bet on which way the market is headed.
