Too Big to Fail: The Inside Story of How Wall Street and Washington Fought to Save the Financial System from Crisis — and Themselves

The issue facing them was this: Unlike a traditional commercial bank, Goldman didn’t have its own deposits, which by definition were more stable. Instead, like all broker-dealers, it relied at least in part on the short-term repo market—repurchase agreements that enabled firms to use financial securities as collateral to borrow funds. While Goldman tended to have longer term debt agreements—avoiding being reliant on overnight funding like that of Lehman, for example—it still was susceptible to the vagaries of the market. That arrangement was something of a double-edged sword. It could bet its own money utilizing enormous amounts of leverage—putting up $1, for example, and using $30 of debt, a practice common in the industry. Bank holding companies like JP Morgan Chase, which were regulated by the Federal Reserve, faced far more restrictions when it came to debt-fueled bets on the market. The downside was that if confidence in the firm waned, that money would quickly evaporate.
