Lincoln to the Rescue
The five biggest Wall Street banks have had the derivatives market (derivatives are bets on whether the price of certain assets will rise or fall, bets thereby “derived” from asset prices) almost entirely to themselves. Last year their revenues from derivatives trading totaled a whopping $22.6 billion. Their advantage comes from their large size, plus government insurance of their commercial deposits that allows them to raise money more cheaply than other financial institutions.

Derivatives lie at the point where the basic saving-and-lending function of commercial banking meets the private casino of Wall Street investment banking. You and I subsidize the biggest players in the casino who, precisely because we subsidize them, have grown too big to fail. The Glass-Steagall Act once prevented the casino from using commercial deposits, but since 1999, when Glass-Steagall was repealed, the game has exploded. That’s part of the reason the giants on Wall Street could make wild bets that ended up threatening the entire economy, costing millions of Americans their jobs and savings, and requiring a massive taxpayer-financed bailout.
